Kimberly is admiring a statue in Newberry Park from 4 meters away. If the distance between the top of the statue to Kimberly's head is 9 meters, how much taller is the statue than Kimberly? If necessary, round to the nearest tenth.

According to the evidence from graph a and graph b, graph a indicates that the model for the data was a good fit because it is a random.

Hence, the correct option is B.

Based on graph a, the residual plot shows a random scattering of points around the horizontal line at y=0. This indicates that the residuals (the differences between the observed and predicted values) are distributed randomly and do not show any clear pattern. This suggests that the data points are evenly distributed around the regression line, indicating a good fit for a linear regression model.

On the other hand, graph b shows a residual plot with a clear pattern or trend. The residuals are not randomly scattered, but instead show a curved pattern or a fan-like shape. This indicates that the model used to fit the data may not be appropriate, as it is not capturing the underlying relationship between the variables accurately.

Hence, the correct option is B.

The equation of the parabola in factored form is: y = 16(z - 1/2)(z - 8)

What is parabola?

A parabola is a symmetrical plane curve that is shaped like an arch. It is a quadratic function and is defined by the equation y = ax² + bx + c, where a, b, and c are constants.

Ryan's reasoning is justified because the z-intercepts of a parabola are the points where the parabola intersects the z-axis, which are the points where x = 0. Therefore, if the parabola can be expressed in the form y = a(x + 1)(x - 4), then its z-intercepts are at x = -1 and x = 4. This is because when x = -1, (x + 1) = 0 and when x = 4, (x - 4) = 0, which makes y = 0, indicating that the parabola intersects the z-axis at these two points.

To find the value of a, we need to use the given information that the y-intercept of the parabola is at (0, 2). Substituting x = 0 and y = 2 into the equation y = a(x + 1)(x - 4), we get:

2 = a(0 + 1)(0 - 4)

2 = -4a

Therefore, a = -1/2. So the equation of the parabola is y = (-1/2)(x + 1)(x - 4), in factored form.

To find the equation of the parabola in factored form y = a(z-p)(z-g), we can use the given information about its intercepts and symmetry axis. Since the symmetry axis is parallel to the y-axis, the parabola is of the form y = a(z - h)² + k, where (h, k) is the vertex. We know that the a-intercepts are -2 and 3, which means that the points (-2, 0) and (3, 0) lie on the parabola. Substituting these points into the equation, we get:

0 = a(-2 - h)² + k

0 = a(3 - h)² + k

Solving for h and k, we get:

h = 1/2

k = 4

Therefore, the vertex is at (1/2, 4), and the equation of the parabola is:

y = a(z - 1/2)² + 4

We can find the value of a by using the fact that the y-intercept is 4. Substituting z = 0 and y = 4, we get:

4 = a(0 - 1/2)² + 4

4 = a(1/4)

a = 16

Therefore, the equation of the parabola in factored form is:

y = 16(z - 1/2)(z - 8), which is sometimes referred to as intercept form because it explicitly shows the intercepts of the parabola on the z-axis.

The distance between the centers of the two wheels is approximately 11.86 feet.

The length of the conveyor belt is equal to the circumference of the circle formed by each wheel plus the distance between the centers of the two wheels.

Let's call the distance between the centers of the two wheels "d". The circumference of each wheel can be calculated using the formula

C = πd

Since each wheel has a diameter of 1 foot, its radius is 0.5 feet. Therefore, the circumference of each wheel is:

C = πd = π(0.5) = 1.57 feet (approx.)

The length of the conveyor belt is given as 15 feet. So we can write

2C + d = 15

Substituting the value of C, we get

The percent increase in her pay is by 26.06% if she takes the new job.

A quantity's percentage increase is a way to represent how much it has grown in comparison to its starting point. The formula is as follows: take the new value, remove the original value, divide the outcome by the original value, and then multiply by 100%. When comparing two quantities, such as incomes, prices, or test scores, it is common to use the percentage increase to gauge how much has changed. A value rise is indicated by a positive percent increase, whilst a value loss is shown by a negative percent increase.

Given that, the pat increases from $8.25 an hour to $8.25 an hour.

percent increase = [(new value - old value) / old value] x 100%

Substituting the values we have:

percent increase = [(10.40 - 8.25) / 8.25] x 100%

percent increase = 26.06%

The formula for the general term of an arithmetic sequence is:

an = 14 - 3(n-1)

Arithmetic progression (AP) is a sequence of numbers in which each term after the first is obtained by adding a fixed constant value, called the common difference, to the preceding term. For example, 2, 4, 6, 8, 10, 12, 14... is an arithmetic progression with a common difference of 2. The formula for the nth term of an arithmetic progression is given by:

an = a1 + (n-1)d

The given sequence 14, 11, 8, 5, 2 is an arithmetic sequence with a common difference of -3.

The formula for the general term of an arithmetic sequence is:

an = a1 + (n-1)d

where:

an = the nth term of the sequence

a1 = the first term of the sequence

d = the common difference between consecutive terms

n = the position of the term we want to find

Using the values given in the sequence, we have:

a1 = 14

d = -3

To find the general term, we need to determine the value of n. Let's assume that the first term of the sequence corresponds to n = 1.

For the first term (n = 1):

a1 = 14

For the second term (n = 2):

a2 = a1 + d = 14 - 3 = 11

For the third term (n = 3):

a3 = a1 + 2d = 14 - 6 = 8

For the fourth term (n = 4):

a4 = a1 + 3d = 14 - 9 = 5

For the fifth term (n = 5):

a5 = a1 + 4d = 14 - 12 = 2

Therefore, the general term for the given sequence is:

an = 14 - 3(n-1)

The tank is upside down square-pyramid, with sides as 4 meter,

Let the height of water at any time "t" be = "h",

The height of the tank is = 12 meter,

Let, the side of the base of pyramid shaped water at any time "t" be = "b",

So, b = (1/3)h   ...because height of pyramid is 12 and each side is of 4, the ratio is 1/3,

The volume of water at nay time "t" is (V) = (1/3)b²h,

⇒ V = (1/3)(1/3h)²h,

⇒ V = h³/27,

Now, dv/dt = (d/dt)(h³/27),

On simplifying further,

we get,

⇒ dv/dt = (h²/9)(dh/dt),

⇒ dh/dt = (9/h²)(dv/dt),

We know that, when the water is 2 meter deep, and if water is pumped out at rate of 23 m³/sec, it means that h = 2, and dv/dt = 23,

Answer: C. The median of 20 is the most accurate to use, since the data is skewed.

The most accurate measure of center to use in this case is the median of 20. This is because the data is skewed, with a few high-value donations (such as the two donations of 55 dollars) that pull the mean up. However, most of the donations are clustered around 10 to 20 dollars. As a result, the median, which is the middle value when the data is sorted in order, is a better representation of the "typical" donation amount.

In this case, the median is 20, which means that half of the donations were less than 20 dollars and half were more. This is a more accurate representation of the central tendency of the data than the mean of 22.7, which is influenced by the high-value donations. Therefore, the charity should use the median of 20 to accurately represent the typical donations received.

Step-by-step explanation:

To find the length of the third side, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).

So, in this case, we have:

x^2 + 6^2 = 10^2

Simplifying this equation, we get:

x^2 + 36 = 100

Subtracting 36 from both sides, we get:

x^2 = 64

Taking the square root of both sides, we get:

x = 8 or x = -8

Since the length of a side of a triangle can't be negative, the length of the third side is x = 8 cm.

The number 8 is in all shapes

So, D = 8

Number C is the largest

For the blue section, we have

F = Blue

For the triangle, we have

DEF = 48

D + E + F = 15

So, we have

EF = 6

E + F = 7

This means that

(E, F) = (1, 6) or (6, 1)

Number 1 is yellow

So, we have

Since F is not yellow, then

A = Green

A and G add up to 7, and A's number is smaller than G's.

So A and G must be (1, 6), (3, 4) because 2 and 7 are not used

Because of the values of E and F, we have

Greg's backyard is 14 yards and 1 foot wide. To summarize, we can say that 42 feet is equivalent to 14 yards and 1 foot.

To convert 42 feet to yards and feet, we need to know that there are 3 feet in 1 yard. We can divide the total number of feet (42) by 3 to get the number of yards, and then take the remainder to get the remaining feet.

So, 42 feet divided by 3 feet/yard equals 14 yards. This means that Greg's backyard is 14 yards wide.

To find the remaining feet, we can multiply the decimal part of the result by 3. So, 0.333 x 3 = 0.999. Since we cannot have a fraction of a foot, we round up to the nearest whole foot, which gives us 1 foot.
