New car prices to fall within is $18,300 - $41,900
Interval of prices would we expect at least 95% of new car prices to fall within Suppose that the average price for new cars has a mean of $30,100, a standard deviation of $5,600 and is normally distributed. Based on this information, the interval of prices that we would expect at least 95% of new car prices to fall within is $18,300 - $41,900.How to solve the problem? We know that the average price of new cars is $30,100 and the standard deviation is $5,600. The normal distribution has 95% of the data points within two standard deviations of the mean. Therefore, the interval of prices that we would expect at least 95% of new car prices to fall within is given by:Lower limit: $30,100 - 2 × $5,600 = $18,300Upper limit: $30,100 + 2 × $5,600 = $41,900Thus, the interval of prices that we would expect at least 95% of new car prices to fall within is $18,300 - $41,900.

Amazon uses a box where the volume can be represented by the expression x^3-2x^2-15x. What are the possible dimensions of the box?
Answer:
See below.
Step-by-step explanation:
The volume of the box is given by the expression.
V(x) = x^3 - 2x^2 - 15x
To find the possible dimensions of the box, we need to solve for the values of x that make the volume positive. A box with negative volume is not physically meaningful.
Setting V(x) > 0, we get.
x^3 - 2x^2 - 15x > 0
Factorizing the left-hand side, we get.
x(x^2 - 2x - 15) > 0
Now, we can find the values of x that make each factor positive.
For x > 0, both factors are positive.
For x^2 - 2x - 15 > 0, we can factor it as (x - 5)(x + 3) > 0. This inequality is true when x < -3 or x > 5.
Therefore, the possible dimensions of the box are.
x > 0 and x < -3, or
x > 0 and x > 5.
However, we need to remember that the dimensions of a physical box must be positive. Therefore, the only valid solution is,
x > 0 and x > 5.
So the possible dimensions of the box are.

Small pizzas at Ponnie's Pizza are cut into 6 pieces. The circumference of a small pizza is 12π inches. A large pizza is cut into 8 pieces. The diameter of a large pizza is 16 inches.
Joannie eats 2 slices of a small pizza. Mark eats 5 slices of a large pizza.
How many times greater are the square inches of pizza that Mark ate than the square inches of pizza that Joannie ate?
Enter your answer, rounded to the nearest tenth, in the box.
Answer:
Mark ate 3.3 times the square inches of pizza than Joannie ate.
Step-by-step explanation:
Small pizzaThe formula for the circumference of a circle is C = 2πr (where r is the radius). If the circumference of a small pizza is 12π inches, then its radius is:
[tex]\implies \sf Radius_{small\;pizza}=\dfrac{circumference}{2\pi}=\dfrac{12\pi}{2\pi}=6\;inches[/tex]
The formula for the area of a circle is A = πr² (where r is the radius).
Therefore, the area of a small pizza is:
[tex]\implies \sf Area_{small\;pizza}=\pi \cdot 6^2=36\pi \; in^2[/tex]
If the small pizzas are cut into 6 congruent pieces, the area of one slice of small pizza is:
[tex]\begin{aligned}\implies \sf Area_{small\;slice}&=\sf \dfrac{Area_{small\;pizza}}{6}\\\\&=\dfrac{36 \pi}{6}\\\\&=6 \pi \; \sf in^2\end{aligned}[/tex]
Therefore, the area of one slice of small pizza is 6π square inches.
[tex]\hrulefill[/tex]
Large pizzaThe diameter of a circle is twice its radius.
If the diameter of a large pizza is 16 inches then its radius is:
[tex]\implies \sf Radius_{large\;pizza}=\dfrac{diameter}{2}=\dfrac{16}{2}=8\;inches[/tex]
The formula for the area of a circle is A = πr² (where r is the radius).
Therefore, the area of a large pizza is:
[tex]\implies \sf Area_{large\;pizza}=\pi \cdot 8^2=64 \pi \; in^2[/tex]
If the large pizzas are cut into 8 congruent pieces, the area of one slice of large pizza is:
[tex]\begin{aligned}\implies \sf Area_{large\;slice}&=\sf \dfrac{Area_{large\;pizza}}{8}\\\\&=\dfrac{64 \pi}{8}\\\\&=8 \pi \; \sf in^2\end{aligned}[/tex]
Therefore, the area of one slice of large pizza is 8π square inches.
[tex]\hrulefill[/tex]
If Joannie eats 2 slices of small pizza, the square inches of pizza she ate is:
[tex]\implies \sf Joannie=2 \times 6 \pi = 12 \pi\;in^2[/tex]
If Mark eats 5 slices of large pizza, the square inches of pizza he ate is:
[tex]\implies \sf Mark =5 \times 8 \pi = 40\pi\;in^2[/tex]
To calculate how many times greater are the square inches of pizza that Mark ate than the square inches of pizza that Joannie ate, divide the area Mark ate by the area Joannie ate:
[tex]\implies \sf \dfrac{40 \pi}{12 \pi} = \dfrac{10}{3}=3.3\;(nearest\;tenth)[/tex]
Therefore, Mark ate 3.3 times the square inches of pizza than Joannie ate.

352.74 empty calories did miya consume on this 1-day menu.
Hence option d. 352.74 empty calories is correct.
According to the my plate analysis report, how many empty calories did Miya consume on this 1-day menu.
Empty calories refer to those calories that are devoid of any nutrient and provide only energy.
Miya's 1-day menu needs to be analyzed to determine the empty calories count.
The options provided are:
a. 793.34 empty calories
b. 693.74 empty calories
c. 593.54 empty calories
d. 352.74 empty calories.
Let us understand the concept of empty calories in detail.
Empty calories refer to the calories provided by foods that contain little to no nutrients, like vitamins and minerals. Common sources of empty calories are sugary snacks and alcohol.
Though these foods provide energy, they lack the essential vitamins, minerals, and fiber that the body requires for optimal health.
Therefore, empty calories should be limited in the diet.
To determine the empty calories consumed by Miya, we need to know the nutrient content of her 1-day menu.
Once the nutrient content is known, we can subtract the total calories from empty calories to determine the number of calories that are not empty.
Let us assume that Miya's total calorie intake for the day is 1500 calories. Out of this, the my plate analysis report says that empty calories should not exceed 362 calories.
Therefore, the non-empty calories will be: 1500 - 362 = 1138 calories
From this, we can determine the correct option.
Let us substitute the values given in the options :
a. 793.34 empty calories: 1500 - 793.34 = 706.66
non-empty calories, which is less than 1138.
Therefore, this option is incorrect.
b. 693.74 empty calories: 1500 - 693.74 = 806.26 non-empty calories, which is less than 1138.
Therefore, this option is incorrect.
c. 593.54 empty calories: 1500 - 593.54 = 906.46 non-empty calories, which is less than 1138.
Therefore, this option is incorrect.
d. 352.74 empty calories: 1500 - 352.74 = 1147.26 non-empty calories, which is greater than 1138.
Therefore, this option is the correct answer.
So, the number of empty calories consumed by Miya on this 1-day menu is 352.74 empty calories.

Find the missing dimension of the trapezoid. 8 in. h 12 in. A = 40 in. h=___in
Answer: h=4
Step-by-step explanation:
Write the equation of a line parrallel to y=1/3x+4 and goes through -6,1
The equation of the line parallel to y = (1/3)x + 4 and passing through (-6, 1) is y = (1/3)x + 3.
To find the equation of a line parallel to y = (1/3)x + 4 and pass through the point (-6, 1), we can use the fact that parallel lines have the same slope. The slope of the given line is 1/3, so the slope of the parallel line must also be 1/3.
Now we have the slope (m = 1/3) and a point on the line (-6, 1), so we can use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
Plugging in the values, we get:
y - 1 = (1/3)(x - (-6))
Simplifying, we get:
y - 1 = (1/3)x + 2
Adding 1 to both sides, we get the final equation:

ezra is redrawing the blueprint shown of a stage he is planning to build for his band. by what percentage should he multiply the dimensions of the stage so that the dimensions of the image are 12 the size of the original blueprint? what will be the perimeter of the updated blueprint?
The perimeter of the updated blueprint will be 24 times the sum of the original length and width.
If Ezra wants to multiply the dimensions of the stage by a certain percentage to make the image 12 times larger than the original, he needs to find out what percentage that is.
To do this, he can divide the desired size of the new stage by the original size of the stage, and then multiply by 100 to get the percentage increase. So, if the original blueprint dimensions are x by y, and he wants to make the image 12 times larger, the new dimensions will be 12x by 12y.
To find the percentage increase, he can use the following formula:
Percentage increase = [(new size - original size) / original size] x 100
In this case, the new size is 12 times the original size, so the formula becomes:
Percentage increase = [(12x * 12y - x * y) / (x * y)] x 100
Simplifying this expression gives:
Percentage increase = [(144xy - x * y) / (x * y)] x 100 = 14300%
Therefore, Ezra needs to multiply the dimensions of the stage by 14300% to make the image 12 times larger than the original blueprint.
To find the perimeter of the updated blueprint, he can use the formula for the perimeter of a rectangle, which is: Perimeter = 2(length + width)
In this case, the length and width have been multiplied by 12, so the new perimeter becomes:
Perimeter = 2(12x + 12y) = 24(x + y)
Therefore, the perimeter of the updated blueprint will be 24 times the sum of the original length and width.

The point on the graph represents Ann's location. She is using a metal detector on the beach to see what she can find. Each unit on the graph represents 2 feet. A pile of bottle caps is located at (4, -10). Find the length of the most direct path between Ann and the pile of bottle caps. Round to the nearest whole number.
Answer:
30 feet
Step-by-step explanation:
Coordinates of Ann: (-4,3)
Coordinates of bottle caps: (4,-10)
Distance from Ann to bottle caps can be found out using the distance formula:
[tex]x_2=4, x_1=-4\\y_2=-3,y_1=-10\\Distance=\sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2 } \\=\sqrt{(4-(-4))^2 + ((-10)-3)^2} \\=15.26\\15\text{ is the answer}[/tex]
This quarter, a local gym has 759 members. That is 65% more than it had last quarter, due to a change in rates. How many members were there last quarter?
Answer:
759=165% of last quarters members so you could divide by 1.65(move the decimal place twice to the left) so you get 460 people were there last quarter
Step-by-step explanation:
Lin completes a 5K using a combination of walking and running. Here are four graphs that represent four possible situations. Each graph shows the distance, in meters, as a function of time, in minutes.
Graph 1
Graph 2
Graph 3
Graph 4
Match each description with a graph that could represent it.
A:
Lin starts out running, but then slows down to a jog. After 10 minutes, she stops for a water break. She then runs the rest of the way.
B:
Lin starts the race walking, gradually getting faster and faster.
C:
Lin jogs at a steady pace for the entire race.
D:
Lin starts out walking, then moves to a steady run. After 15 minutes, she stops to stretch a cramped leg. Then, she walks the rest of the way.
.Graph 4: A - Lin initially jogs after starting off running. She comes to a stop for a water break after ten minutes. After that, she continues to run.
what is graph ?A graph in mathematics is a picture of a group of things and the connections or interactions between them. The connections or relationships between the objects in a graph are typically represented by lines or edges, whereas the objects themselves are typically represented by points or vertices. Many different real-world phenomena, including social networks, transportation networks, and financial markets, are modelled and represented using graphs. Also, they can be used to examine and research many traits and qualities of things and interactions, like connectedness, separation, and clustering.
given
Graph 1: Lin begins by walking before gradually transitioning to a steady run. She pauses after fifteen minutes to stretch her strained leg. She continues to walk the remaining distance.
Graph 2: B - Lin begins the race by strolling and then progressively picks up speed.
Graph 3: C - Lin maintains a constant speed throughout the entire race.
Graph 4: A - Lin initially jogs after starting off running. She comes to a stop for a water break after ten minutes. After that, she continues to run.

matrix flipped 3 coins. what is the probability that all three coins will land on the same side
Answer:
When flipping a coin, there are two possible outcomes: heads or tails. The probability of getting heads on any one flip is 1/2, and the probability of getting tails is also 1/2.
To find the probability that all three coins will land on the same side (either all heads or all tails), we can use the multiplication rule of probability, which states that the probability of two independent events occurring together is the product of their individual probabilities.
So, for each coin flip, there are two possible outcomes, and the probability of getting either outcome is 1/2. To find the probability that all three coins will land on the same side, we need to find the probability of getting either all heads or all tails.
The probability of getting all heads is:
(1/2) x (1/2) x (1/2) = 1/8
Similarly, the probability of getting all tails is also 1/8.
So, the probability of all three coins landing on the same side is:
1/8 + 1/8 = 2/8 = 1/4
Therefore, the probability that Matrix will flip 3 coins and all three coins will land on the same side is 1/8 or 0.125, which can also be written as a fraction or percentage.
A boat heading out to sea starts out at Point AA, at a horizontal distance of 787 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 13^{\circ} ∘ . At some later time, the crew measures the angle of elevation from point BB to be 2^{\circ} ∘ . Find the distance from point AA to point BB. Round your answer to the nearest tenth of a foot if necessary.
After answering the prοvided questiοn, we can cοnclude that Rοunding equatiοn tο the nearest tenth οf a fοοt, we get the final answer οf apprοximately 205917.5 feet.
What is equatiοn?An equatiοn is a statement in mathematics that states the equality οf twο expressiοns. An equatiοn has twο sides that are separated by an algebraic equatiοn (=). Fοr example, the argument "2x + 3 = 9" asserts that the statement "2x + 3" equals the value "9". The gοal οf equatiοn sοlving is tο determine which variable(s) must be changed in οrder fοr the equatiοn tο be true. Simple οr cοmplicated equatiοns, regular οr nοnlinear equatiοns, and equatiοns with οne οr mοre factοrs are all feasible. In the equatiοn "x² + 2x - 3 = 0," fοr example, the variable x is raised tο the secοnd pοwer. Lines are used in a variety οf mathematical disciplines, including algebra, calculus, and geοmetry.
Let's first draw a diagram to visualize the problem:

* B
2 degrees
From triangle ABL:
tan(13 degrees) = h/787 feet
where h is the height of the lighthouse above sea level.
[tex]$\begin{array}{l}{\rm{t a n(2^{\circ})=h/(787-x)f e e t}}\\ {{\rm h=787\ f e e t \times t a n(13^{\circ})162.0\ f e e t}}\\ {{\rm x=787 f e e t-h/t a n(2^{\circ})205\ fe e t}}\end{array}$[/tex]
Therefore, the distance between AA and BB is approximately:
[tex]$\begin{array}{l}\rm {\sqrt{(787\ f e e t)^{2}+x^{2})}\\\rm=205917.5\ f e e t\\\rm=39118.2\ m e t e r s \end{array}$[/tex]
Rounding to the nearest tenth of a foot, we get the final answer of approximately 205917.5 feet.
