The Garden B has 76.47% more data than Garden A.

Percentage is a way of expressing a number as a fraction of 100. It is a commonly used method to represent proportions, rates, and percentages in various fields such as finance, economics, and statistics.

Let's first find the actual values of Garden A's and Garden B's data:

For Garden A, we know that 75% of its data is equal to 12.75. We can use this information to set up an equation:

0.75x = 12.75

Solving for x, we get:

x = 12.75 / 0.75 = 17

Therefore, Garden A's total data is 17.

For Garden B, we know that 50% of its data is equal to 15. We can use this information to set up an equation:

0.5x = 15

Solving for x, we get:

x = 15 / 0.5 = 30

Therefore, Garden B's total data is 30.

Now, to find how much more percent Garden B has than Garden A, we can use the formula:

percent difference = |(Garden B - Garden A) / Garden A| * 100

Plugging in the values, we get:

percent difference = |(30 - 17) / 17| * 100 = 76.47%

Therefore, Garden B has 76.47% more data than Garden A.

A and B are complements of each other, so A + B = 90°. It follows that B = 90° - A, meaning sin A = cos(90° - A).

Using the alternate angles theorem,

(a) The measure of angle ABQ is 54°

(b) The measure of angle CDE is 128°

From the question, we are to determine the measure of the unknown angles

First, let us produce line BCD to Z

Then,

m ∠FDZ = m ∠BCP

From the given diagram

m ∠BCP + 148° = 180° (Sum of angles on a straight line)

m ∠BCP = 180° - 148°

m ∠BCP = 32°

Therefore,

m ∠FDZ = 32°

Also,

m ∠EDZ = 84° - m ∠FDZ

m ∠EDZ = 84° - 32°

m ∠EDZ = 52°

m ∠CDE + m ∠EDZ = 180° (Sum of angles on a straight line)

m ∠CDE + 52° = 180°

m ∠CDE = 180° - 52°

m ∠CDE = 128°

m ∠ABQ + m ∠QBD = m ∠CDE (Alternate interior angles)

m ∠ABQ + 74° = 128°

m ∠ABQ = 128° - 74°

m ∠ABQ = 54°

Hence,

m ∠ABQ is 54°

To find the center and radius of the circle, we need to rewrite the equation in standard form, which is: (x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center of the circle and r is the radius. To rewrite the given equation in standard form, we need to complete the square for both x and y terms. Let's start with the x terms: x^2 - 12x = -(y^2 - 2y + 33) To complete the square for x, we need to add and subtract (12/2)^2 = 36: x^2 - 12x + 36 - 36 = -(y^2 - 2y + 33) (x - 6)^2 - 36 = -(y^2 - 2y + 33) Now

To find the center and radius of the circle given by the equation:

x^2 + y^2 -12x + 2y + 33 = 0

We need to rewrite the equation in standard form, which is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center of the circle and r is the radius.

To do this, we need to complete the square for both x and y terms by adding and subtracting appropriate terms inside the parentheses.

(x^2 - 12x) + (y^2 + 2y) + 33 = 0

To complete the square for x terms, we need to add (12/2)^2 = 36 inside the first set of parentheses and subtract it from the equation:

(x^2 - 12x + 36) + (y^2 + 2y) + 33 - 36 = 0

(x - 6)^2 + (y^2 + 2y) - 3 = 0

To complete the square for y terms, we need to add (2/2)^2 = 1 inside the second set of parentheses and subtract it from the equation:

(x - 6)^2 + (y^2 + 2y + 1) - 4 = 0

(x - 6)^2 + (y + 1)^2 = 4

Now we can see that the equation is in standard form, where (h, k) = (6, -1) is the center of the circle, and r^2 = 4, so the radius is r = 2.

Therefore, the center of the circle is (6, -1) and the radius is 2.

Answer:If 104° is a measure of one of the vertical angles formed by the intersection of two straight lines, then the measure of the other vertical angle would also be 104°. This is because vertical angles are always congruent, which means they have the same measure.

Step-by-step explanation:

Matthew's family cannot drive for 25 days without the warning light coming on, and they will need to refill the tank before that point.

If the car uses 0.6 gallons of fuel per day, then in 25 days, it will use:

= 0.6 gallons/day × 25 days

= 15 gallons

This means that if Matthew's family starts with a full tank of 14 gallons, they will not be able to drive for 25 days without running out of fuel.

The question asks if they can drive for 25 days without the warning light coming on. If the warning light comes on when there is 1.5 gallons or less of fuel remaining, then Matthew's family can drive for:

= 14 gallons - 1.5 gallons

= 12.5 gallons before the warning light comes on.

Since they use 0.6 gallons of fuel per day, they can drive for:

= 12.5 gallons / 0.6 gallons/day

≈ 20.8 days without the warning light coming on.

Therefore, they cannot drive for 25 days without the warning light coming on, and they will need to refill the tank before that point.

The probability that a uniformly distributed random variable between 12 and 41 is between 22 and 35 is 41.7%.

Since the random variable is uniformly distributed between 12 and 41, the probability density function (PDF) of the random variable is constant within that interval and zero outside of it. Let X be the random variable between 12 and 41. Then,

f(x) = 1/(41-12) = 1/29, for 12 ≤ x ≤ 41

The probability that the random variable is between 22 and 35 can be found by integrating the PDF over the interval [22, 35]:

P(22 ≤ X ≤ 35) = ∫(22 to 35) f(x) dx = ∫(22 to 35) 1/29 dx

Using the definite integral, we get:

P(22 ≤ X ≤ 35) = [x/29] from 22 to 35

P(22 ≤ X ≤ 35) = (35/29 - 22/29) = 13/29

So, the probability that the random variable is between 22 and 35 is 13/29, which is approximately 0.4483 or 44.8% when expressed as a percentage rounded to one decimal place.

There is no significant difference in the average scores of two groups of SOC 390 students who took Exam 1 in the spring and fall semesters, respectively, as per the two-sample t-test with a p-value of 0.388.

The average score of the spring group of 50 students in SOC 390 on Exam 1 was 80, with a standard deviation of 12, while the average score of the fall group of 52 students was 81, with a standard deviation of 6. To determine if the difference in the means of the two groups is statistically significant, we can use a two-sample t-test.

Assuming unequal variances, the t-value for the two groups is 0.87, with a corresponding p-value of 0.388. Since the p-value is greater than the standard alpha level of 0.05, we fail to reject the null hypothesis that the two groups have equal means.

Will is therefore more likely to choose a blue tile before choosing a yellow tile.

The likelihood or possibility of an event happening is measured by probability. It is represented by a number in 0 and 1, with 0 denoting an impossibility and 1 denoting a certainty. By dividing total number of favourable possibilities by the total number of potential outcomes, one can determine the probability of an occurring. In other respects, it is the proportion between the amount of alternative outcomes to the number of possible ways the event could happen. In many fields, including statistics, mathematics, physics, economics, and the social sciences, probability is used to create predictions and well-informed judgements based on the likelihood that events will occur.

We must take into account the likelihood of each event and then combine them together in order to get the probability of choosing a blue tile first, followed by a yellow tile.

Will picks blue first, then yellow, therefore P(Will) = (6/15) * (5/15) = 2/15

The likelihood that Joan will first choose a blue tile is the same as before: 6/15.

Joan picking a yellow tile on her second pick thus has a 5/14 chance of doing so. Hence, the likelihood that Joan will choose a blue tile first, followed by a yellow tile, is:

Step-by-step explanation:

The total number of marbles in the bag is 3+2+4+1=10.

The probability of pulling a red marble on the first draw is 3/10, since there are 3 red marbles out of 10 total marbles.

Since we are not replacing the marble after each draw, the probability of pulling another red marble on the second draw decreases slightly. After one red marble has been drawn, there are only 2 red marbles left out of 9 total marbles. So the probability of pulling a second red marble is 2/9.

Therefore, the theoretical probability of pulling two red marbles without replacement is:

P(Red, Red) = P(Red on first draw) x P(Red on second draw, given that the first marble was red)

= 3/10 x 2/9

= 1/15

So the theoretical probability of pulling a red marble without replacement is 1/15 or approximately 0.067 or 6.7%.

The value of the theoretical probability of pulling a red marble without replacement is,

= 3/10

= 0.3

= 30%

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

Hence, Total marbles = 3 + 2 + 4 + 1 = 10

Thus, The value of the theoretical probability of pulling a red marble without replacement is,

P = Desired Outcomes / Total number of outcomes.

P = 3 / 10

P = 0.3

The sum of the interior angles of the polygon is 540° by the Sum of angles property of pentagon.

We know that the diagram is a plane figure with five sides, which means it is a Pentagon (Five-sided polygon), when from one vertex a line was drawn to the non-consecutive vertices, we need to find the sum of the interior angles of the polygon:

The total of interior angles in a polygon can be found by multiplying the quantity of triangles by 180°. It is noticeable that the number of triangles is consistently two less than the number of sides.

As a result, we can conclude that the formula for determining the sum of interior angles in a convex polygon with n sides is:

S = (n - 2) × 180°

This formula provides the sum of interior angles for any polygon.

Solution: A pentagon has five sides.

Therefore, by the angle sum formula we know that:

S = (n − 2) × 180°

Here we know that n = 5 as pentagon has 5 sides,

Hence, by the Sum of angles of pentagon = (5 − 2) × 180°

The area of the triangle is approximately 11.524 km²

What is an area?

We can find the area of the triangle using the formula:

Area = (1/2) * a * b * sin(C)

where a and b are the lengths of the two sides and C is the angle between them.

In this case, a = 5 km, b = 7 km, and C = 143°. However, before we can use this formula, we need to convert the angle to radians. We can do this by multiplying by pi/180:

C = 143 * pi/180

C ≈ 2.495 radians

Now we can substitute the values into the formula and calculate the area:

Area = (1/2) * 5 km * 7 km * sin(2.495)

Area ≈ 11.524 km²

Therefore, the area of the triangle is approximately 11.524 km².

What is triangle?

A triangle is a 2-dimensional geometric shape that has three sides and three angles. It is one of the basic shapes in geometry and is used in various fields such as mathematics, engineering, architecture, and art. Triangles can be classified into different types based on their sides and angles, such as equilateral, isosceles, scalene, acute, right, and obtuse triangles.
