1.) Which variable did you plot on the x-axis, and which variable did you plot on the y-axis?
x-axis represents people's arms span, y-axis represents their corresponding height

2.) Explain why you assigned the variables in that way.
because you can find the height of people(y) by plugging arm span in x. And i can find people's arm span(x) by plugging height as y

<h2>Volume of Sphere</h2>

1. What is the radius of the stone sphere?

- To know what is the radius divide is by 2.

$\large \tt 6 \div 2 = 3$

Therefore, the radius of the stone sphere is 3in

2. What is the volume of the stone sphere?

- Using the formula in finding the Volume of Sphere $\tt V = \frac{4}{3}\pi r^3$ to get the answer. Where the volume of the sphere is $\tt\frac{4}{3}\:\:\:\:\pi$ multiplied by the cube of the radius.

$\tt V = \frac{4}{3}\pi r^3$
$\tt V = \frac{4}{3}\times 3.14\times 3in^3$
$\tt V = \frac{4}{3}\times 3.14\times 27in$
$\tt V = \frac{4}{3}\times 84.78in$
$\tt V = \frac{339.12in}{3}$
$\tt V = 113.04in^3$

Therefore, the volume of the stone sphere is 113.04in³

3. Another stone sphere for the garden has a diameter of 10 inches. What is the volume of the stone sphere? Use 3.14 for <em>π</em>, and round to the nearest hundredth.

- Using the formula in finding the Volume of Sphere $\tt V = \frac{4}{3}\pi r^3$ to get the answer. Where the volume of the sphere is $\tt\frac{4}{3}\:\:\:\:\pi$ multiplied by the cube of the radius.

$\tt V = \frac{4}{3}\pi r^3$
$\tt V = \frac{4}{3}\times 3.14\times 5in^3$
$\tt V = \frac{4}{3}\times 3.14\times 125in$
$\tt V = \frac{4}{3}\times 392.5in$
$\tt V = \frac{1570in}{3}$
$\tt V = 523.33in^3$

<h3>Explanation</h3>

Therefore, the volume of the stone sphere is 523.33in³

Explanation: A diagonal of a rectangle cuts the rectangle into 2 right triangles with sides equal to the sides of the rectangle and with a hypotenuse that is the diagonal. All you need to do is use the pythagorean theorem: where a and b are the sides of the rectangle and c is the length of the diagonal.

Scores on the GRE (Graduate Record Examination) are normally distributed with a mean of 573 and a standard deviation of 84. Us

harkovskaia [24]

Answer:

The percentage of people taking the test who score between 489 and 573 is 34%.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of 573, standard deviation of 84

Percentage of people taking the test who score between 489 and 573

The mean is 573.

489 = 573 - 84, which means that 489 is one standard deviation below the mean.

The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are below the mean.

So between one standard deviation below the mean and the mean, the percentage is 68/2 = 34%

The percentage of people taking the test who score between 489 and 573 is 34%.

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is

Paladinen [302]

Answer:

i think the answer is 125.66 (or 125.6 if you use 3.14 as pi)

Step-by-step explanation:

First find the area of the blue circle by multiplying pi times the radius squared to get 380.13 (or 379.94 if multiplied 3.14)

Then find the area of the orange circle by doing the same thing to get 254.47

(or 254.34 if multiplied by 3.14)

finally subtract 380.13-254.47 to get 125.66.

(or 125.6)
