B. 4 m
C. 12 m
D. 18 m
Find w.
12 m
15 m
area = 114 m²
The missing length is 8m which is option A.
Length calculation.
To find the missing length, we need to use the formula for the area of a rectangle:
area = length x width
We are given the area as 114 m² and the width as 15 m. Let's substitute these values into the formula:
114 = length x 15
Solving for length, we get:
length = 114/15
length = 7.6
Therefore, the missing length is approximately 7.6 m.
However, none of the given answer choices match this value exactly. The closest answer is A. 8 m, which is off by only 0.4 m. Therefore, A. 8 m is the best answer choice.

if a sample of shoppers showed stating that the supermarket brand was as good as the national brand, what is the p-value (to decimals)?
The p-value is 0.046, or 4.6% if a sample of shoppers showed stating that the supermarket brand was as good as the national brand.
To calculate the p-value, we use null and alternative hypotheses, as well as the test statistic and its distribution under the null hypothesis.
By the null hypothesis, we can say that supermarket brands are as good as national brands, and by the alternative hypothesis, we can say that supermarket brands are not as good as national brands.
This hypothesis can be tested by performing a two-tailed z-test for proportions.
In a sample of n shoppers, say that x shoppers say that supermarket brands are as good as domestic brands. The sample percentage can be calculated as follows:
p hat = x/n
in the null hypothesis, the sample proportion is equal to the hypothesized proportion, that is 0.5
The test statistic for a two-sided z-test for proportions is given by:
z = (p-hat - p0) / sqrt(p0(1-p0)/n)
where p0 is the hypothesized proportion under the null hypothesis.
In this case, we have:
p-hat = 0.5
p0 = 0.5
n = sample size
The null hypothesis states that the supermarket brand is as good as the national brand, so we would expect the proportion of shoppers who state this to be 0.5.
If the test statistic z falls in the rejection region (i.e., if |z| > 1.96 for a significance level of 0.05),
we would reject the null hypothesis and conclude that there is evidence to suggest that the supermarket brand is not as good as the national brand.
If the test statistic falls in the non-rejection region (i.e., if |z| <= 1.96 for a significance level of 0.05),
we would fail to reject the null hypothesis and conclude that there is insufficient evidence to suggest that the supermarket brand is not as good as the national brand.
To calculate the p-value, we need to find the probability of getting a test statistic as extreme or more extreme than the one we observed, assuming the null hypothesis is true.
For a two-tailed test, the p-value is twice the observed area of the tails above the absolute value of the test statistic.
Assuming the sample size is large enough, the distribution of the test statistic can be approximated as a standard normal distribution under the null hypothesis.
Suppose in a sample of 100 shoppers, 50 said that supermarket brands are as good as domestic brands. after that:
p hat = 0.5
p0 = 0.5
n=100
The test statistic is:
z = (p hat - p0) / sqrt(p0(1-p0)/n) = 0 / sqrt(0.5 * 0.5 / 100) = 0
The p-value is the probability that the test statistic is extreme or more extreme than 0. This is the probability of getting further away from the 50/100 ratio or 0.5 in either direction.
p-value = P(p hat <= 0.4 or p hat >= 0.6) = 2 * P(p hat <= 0.4) = 2 * P(Z <= ( 0.4 - 0.5) / sqrt (0.5 * 0.5 / 100) ) = 2 * P(Z <= -2) ≈ 0.046
where Z is a standard normal random variable.
Therefore, the p-value is approximately 0.046, or 4.6%.

For each of the figures write an absolute value equation that has the following solution set.
The absolute value equation that has the solution set with digits -18, 0, and X on a number line is :
|X| = X if X ≥ 0
|X| = -X if X < 0
What do you mean by term Equation?An equation is a mathematical statement that shows the equality of two expressions. It typically includes one or more variables (represented by letters) and may also include constants, coefficients, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation.
If the solution set for the absolute value equation has digits -18, 0, and X on a number line, then the equation must have two separate cases: one where X is positive and one where X is negative. We can write the absolute value equation as:
|X| = X for X ≥ 0
|X| = -X for X < 0
To include the values -18 and 0 in the solution set, we need to check each case separately:
|X| = X if X is greater than 0 or zero. The equation X = a must therefore be resolved, where an is either -18 or 0. As X 0 is satisfied by only one value in the solution set, the case's solution is X = 0.
Example 2: X < 0
When X is negative, |X| equals -X. So, we must find a, where an is either -18 or 0, to solve the equation -X = a. This case's solution is X = 18, as it is the only value in the solution set that satisfies the condition X 0.
As a result, the absolute value equation whose answer is represented by the numbers -18, 0 and X on a number line is:
|X| = X if X ≥ 0
|X| = -X if X < 0
or
|X| = 0 if X = 0
|X| = 18 if X < 0

O(0,3) form a triangle. Find the desired slopes and lengths, then fill in the words that characterize the triangle.
Based on the lengths of the sides, we can see that the triangle is scalene. Based on the slopes of the sides, we can see that the triangle is acute since all the slopes are negative or less than 1.
What is triangle?A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed.
To find the desired slopes and lengths of the triangle formed by the points M(-7, 8), N(-1, 9), and O(0, 3), we can use the distance formula and the slope formula.
Distance formula:
The distance between two points (x₁, y₁) and (x₂, y₂) is given by:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
Using this formula, we can find the lengths of the sides of the triangle:
Length of MO:
d(MO) = √((0 - (-7))² + (3 - 8)²) = √(7² + 5²) = √(74)
Length of NO:
d(NO) = √((-1 - (-7))² + (9 - 8)²) = √(6² + 1²) = √(37)
Length of MN:
d(MN) = √((-1 - (-7))² + (9 - 8)²) = √(6² + 1²) = √(37)
Slope formula:
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:
m = (y₂ - y₁) / (x₂ - x₁)
Using this formula, we can find the slopes of the sides of the triangle:
Slope of MO:
m(MO) = (3 - 8) / (0 - (-7)) = -5/7
Slope of NO:
m(NO) = (9 - 8) / (-1 - (-7)) = 1/6
Slope of MN:
m(MN) = (9 - 8) / (-1 - (-7)) = 1/6
Characterization of the triangle:
Based on the lengths of the sides, we can see that the triangle is scalene (no two sides have the same length). Based on the slopes of the sides, we can see that the triangle is acute (all angles are less than 90 degrees) since all the slopes are negative or less than 1. Additionally, we can see that the side MO is the longest side of the triangle, and since the slope of MO is negative, we can conclude that the angle opposite side MO is the largest angle in the triangle.

The probability in question is a right-tail probability because it is asking for the probability that the mean bond percent for the sample will be at least 28 percent, which is greater than the mean of 26.9 percent.
To calculate the probability, first find the z-score:
z = (sample mean - population mean) / (population standard deviation / sqrt(sample size))
z =[tex] (28 - 26.9) / (3.6 / sqrt(35))[/tex]
z = [tex] 1.1 / (3.6 / 5.916)[/tex]
z =[tex] 1.1 / 0.608[/tex]
z ≈ [tex] 1.809[/tex]
Using the z-table, the area to the left of this z-score is 0.965. Since we are looking for the right-tail probability, we need to subtract this value from 1:
Probability = 1 - 0.965
Probability ≈ 0.035
Thus, the probability that the mean bond percent for the sample will be at least 28 percent is approximately 0.035. The correct answers are right-tail probability and 0.035.

Question: The shape below is made of two rectangles joined together. 5 cm 9 cm 8 cm 5 cm Find the total area of the shape.
Please help and show process for any of these questionss
Using equations,
8. The original dimensions of the rectangle are:
Length = 6m and Width = 2m.
9. The meter contains the following:
Value of nickels = 0.63
Value of dime = 2.26
Value of quarters = 0.21
10. Volume of the sphere is V. So, the value of r will be:
r = ∛ (3v/4π)
11. Solving for the linear equation we can get the value of m = -1
Define equations?A mathematical statement that has two expressions with equal values separated by the symbol "equal to" is called an equation.
In the question,
1. Let the length of the rectangle be = x.
Let the width of the rectangle be = w.
Given,
l = 3w
When the width is increased by 4 meters, (w + 4) meters is the width now.
Then, the rectangle becomes a square.
That means length and width are equal.
l = w+4
Using l from the 1st equation,
3w = w + 4
Subtracting w from both sides,
⇒ 3w - w = 4
⇒ 2w = 4
Diving both sides by 2,
⇒ w = 2 meters.
We know, l = 3w
l = 3 × 2
l = 6 meters.
2. Here,
Let nickels be n.
Let dimes be d.
Let quarters be q.
Given,
Triple the number of quarters as nickels, so:
3q = n
Solving this for q,
q = n/3
Dimes is one than double the times of nickels, so:
d = 2n + 1
Total value of coins = $3.10
So, n + d + q = 3.10
Substituting the value of q and d,
⇒ n + 2n + 1 + n/3 = 3.10
⇒ 3n + n/3 = 3.10 - 1
⇒ (9n+n)/3 = 2.10
⇒ 10n = 6.3
⇒ n =0.63.
We can now find,
d = 2n + 1
= 2 × 0.63 + 1
= 1.26 + 1
= 2.26
q = n/3
= 0.63/3
= 0.21
3. Given,
Volume of sphere,
V = 4/3 × π × r³
Solving for r,
Multiply 3/4 on both sides,
⇒ 3v/4 = π r³
Divide both sides by π,
⇒ 3v/4π = r³
Now, taking cube root on both sides we get,
r = ∛ (3v/4π)
4. Now given a linear equation,
[tex]y=-2x^{m+2}[/tex]
As the equation is a linear equation,
The value of (x, y) we can take as (0,0)
So, 1 = m +2
⇒ m = -1

What fraction do you get from putting together 8 copies of the unit fraction 1/2? Explain how you found the numerator.
When you put together 8 copies of the unit fraction 1/2, you are essentially adding 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2.
To add fractions, you need to make sure the denominators are the same. In this case, all the fractions already have the same denominator of 2.
So, we can add the numerators together:
1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 8/2
Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:
8/2 = 4
Therefore, putting together 8 copies of the unit fraction 1/2 gives us a fraction of 4/1, or simply 4.

The vertex of the quadratic function f(x) = -2x^2 + 8x is (2, 8).
Step-by-step explanation:
To find the vertex of the quadratic function f(x) = -2x^2 + 8x, we first need to find the x-coordinate of the vertex using the formula:
x = -b / 2a
where a = -2 and b = 8. Substituting these values, we get:
x = -8 / 2(-2) = 2
Now, to find the y-coordinate of the vertex, we can substitute this value of x back into the equation: f(2) = -2(2)^2 + 8(2) = 8

The problem involves a line segment divided into two parts in a specific ratio. The ratio of the length of the lesser part to the length of the greater part is found to be (√2 - 1).
Let the length of the whole line segment be x, and let y be the length of the greater part. Then the length of the lesser part is (x - y).
According to the problem statement, the ratio of the lesser part to the greater part is the same as the ratio of the greater part to the whole. Mathematically, we can write this as:
(x - y)/y = y/x
Simplifying this equation, we get:
x^2 - y^2 = y^2
x^2 = 2y^2
Taking the square root of both sides, we get:
x = y√2
Therefore, the value of the ratio of the lesser part to the greater part is:
(x - y)/y = (√2 - 1)
So, the answer will be (√2 - 1).

Question: Write the equation of a line parallel to y = x -5 that goes through (7,0).
To find the equation of a line parallel to y = x - 5 that goes through (7,0), we need to use the fact that parallel lines have the same slope.
The slope of the line y = x - 5 is 1, since the coefficient of x is 1. Therefore, the slope of the parallel line we want to find is also 1.
Using the point-slope form of a line, we can write the equation of the parallel line as:
y - y1 = m(x - x1)
where (x1, y1) is the point (7,0) and m is the slope of the line, which we know is 1.
Plugging in the values, we get:
y - 0 = 1(x - 7)
Simplifying, we get:
y = x - 7
Therefore, the equation of the line parallel to y = x - 5 that goes through (7,0) is y = x - 7.
Answer:
y = x - 7
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 5 ← is in slope- intercept form
with slope m = 1
• Parallel lines have equal slopes , then
y = x + c ← is the partial equation
to find c substitute (7, 0 ) into the partial equation
0 = 7 + c ( subtract 7 from both sides )
- 7 = c
y = x - 7 ← equation of parallel line

Sally Brown bought a house with a 10% adjustable rate mortgage for 20 years. She was paying $9.66 monthly per thousand on her original loan. At the end of 4 years she owes the bank $55,000. Interest has now gone up to 12%, the bank can renew the mortgage at this rate or Sally can pay the full $55,000. Sally renews the mortgage and will pay $11.02 monthly per thousand on this loan.
What is the amount of the old and new monthly payment? What is the percent of increase in her new monthly payment (to the nearest tenth)?
old payment = $
new payment = $
% increase
As a result, the percentage decrease in her new monthly payment is 18.1%. (to the nearest tenth).
How to calculate the monthly payment?To begin, we must determine the original loan amount. Using the information provided, we can construct the following equation:
$55,000 = P(1 + 0.10)^4
P denotes the original loan amount.
When we solve for P, we get:
P = $38,574.09
The old monthly payment is calculated as follows:
$38,574.09 / 1000 x $9.66 = $372.64
We must now compute the new loan amount. Because Sally renewed her mortgage at a 12% interest rate, we can apply the same formula as before, but with a new time period of 16 years (since 4 years have already passed):
Now, we need to calculate the new loan amount. Since Sally renewed the mortgage at a 12% interest rate, we can use the same formula as before, but with a new time period of 16 years (since 4 years have already passed):
$55,000 = P(1 + 0.12)^16
Solving for P, we get:
P = $27,703.25
The new monthly payment can be calculated as:
$27,703.25 / 1000 x $11.02 = $305.23
To find the percent increase, we can use the following formula:
percent increase = ((new value - old value) / old value) x 100
Plugging in the values, we get:
percent increase = (($305.23 - $372.64) / $372.64) x 100 = -18.1%
So the percent of decrease in her new monthly payment is 18.1% (to the nearest tenth).

or watch a video clare streams a classical music station while she's doing chores on the weekends. here are the types of musical pieces she has listened to so far this weekend: overture, symphony, sonata, concerto, symphony, sonata, overture, symphony, opera, sonata, concerto based on the data, what is the probability that the next piece clare listens to will be a concerto?
If Clare streams a classical music station while doing chores, then probability that next piece will be a concerto is 2/11.
In order to calculate the probability that the next-piece Clare listens to will be a concerto, we count the number of concertos in the list of pieces she has already listened to and divide by the total number of pieces.
From the given list,
The total number of pieces of music = 11;
The number of concerto is = 2;
So, probability that next piece Clare listens to will be a concerto is:
⇒ P(concerto) = (number of concertos)/(total number of pieces);
⇒ 2/11
Therefore, the required probability is 2/11.

Simon is taking A trip from Orlando Fl, to sacremento, California which is about 2,804 miles. On average his car gets 48.6 miles for every 2 gallons of gas. How many gallons of gas does Simon need for his trip? Round your answer to the nearest tenth.
Simon needs approximately 48.6 gallons of gas for his trip from Orlando, FL to Sacramento, CA.
To calculate the number of gallons of gas Simon needs for his trip, you can use the following formula:
Gallons = Miles / Miles per gallon
First, convert the distance of 2,804 miles to miles per gallon by dividing by the car's average mileage per 2
gallons:2,804 / 48.6 = 57.75 mpg
Then, use this value to calculate the number of gallons of gas Simon needs for his trip:
Gallons = Miles / Miles per gallon
Gallons = 2,804 / 57.75
Gallons ≈ 48.6 gallons
Therefore, Simon needs approximately 48.6 gallons of gas for his trip from Orlando, FL to Sacramento, CA.
The answer should be rounded to the nearest tenth, so the final answer is 48.6 gallons.

we use the definition of supplementary angles again to conclude that ∠3 and ∠5 are supplementary.
To prove that ∠3 and ∠5 are supplementary, we can use the following steps:
Given: w ∥ x and y is a transversal.
∠1 ≅ ∠5 by the corresponding angles postulate.
By definition, ∠3 and ∠1 are a linear pair, so they are supplementary.
Therefore, m∠3 + m∠1 = 180 by the definition of supplementary angles.
Substituting m∠5 for m∠1, we get m∠3 + m∠5 = 180.
Therefore, by the definition of supplementary angles, ∠3 and ∠5 are supplementary.
In step 1, we use the corresponding angles postulate, which states that when two parallel lines are cut by a transversal, the pairs of corresponding angles are congruent. In step 2, we use the definition of a linear pair, which states that when two angles form a line, they are supplementary. In step 3, we use the definition of supplementary angles, which states that the sum of two supplementary angles is 180 degrees. In step 4, we substitute m∠5 for m∠1, since we know that ∠1 ≅ ∠5. Finally, in step 5, we use the definition of supplementary angles again to conclude that ∠3 and ∠5 are supplementary.
