Answer:
r = 2 and n = 3
Step-by-step explanation:
9 = r + 3+ 4
9 = r + 7
r = 2
10 = n +2 + 5
10 = n + 7
n = 3
Answer:
r = 2 ft
n = 3 ft
area = 61 ft²
explanation:
total length : 10 fttotal width : 9 ft-------------------------------
n + 2 + 5 = 10 n = 10 - 7n = 3 ft-------------------------------
r + 3 + 4 = 9 r = 9 - 7r = 2 ft-----------------------------
Area of the entire figure:
length * width9 ft * 10 ft90 ft²Area of the missing side:
5 * (3+2) + 2 * 229 ft²So area of the shape:
90 ft² - 29 ft²61 ft²help plsssssssssssssssssssssss

Suppose the monthly charges for cell phone plans in the U. S. Are normally distributed with a mean of $62 and a standard deviation of $10. What is the proportion of cell phone plans charging less than $42 a month for service?
Using the normal distribution, it is found that 0.0228 = 2.28% of cell phone plans charge less than $42 a month for service.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 62, \sigma = 10[/tex].
The proportion of cell phone plans charging less than $42 a month for service is the p-value of Z when X = 42, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{42 - 62}{10}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a p-value of 0.0228.
0.0228 = 2.28% of cell phone plans charge less than $42 a month for service.

4. A cube has a volume of 64 m². What is the cube's surface area?
12 points!!! <333
Answer:
Surface area = 96 m^2
Step-by-step explanation:
Let's cube root the volume to find the length of one side of the cube.
[tex]64^\frac{1}{3} = 4[/tex]
Therefore each side is 4 m.
Surface area of one side = 4x4 = 16
A cube has 6 sides.
Total surface area of the cube = 16*6 = 96 m^2

Answer:
the last one (bottom right)
Step-by-step explanation:
4×pi is the same as twice around the whole circle to the beginning. it is the same as 0°, and cos(0) = 1, and then -2×cos(0) = -2
so, we only need to look, where the function reaches -2.
it should be at x = 0, x = 0.5 and x = 1.

Answer: Choice D
181 grams
======================================================
Explanation:
First we need to find the volume of the tennis ball
Since the diameter is d = 6 cm, it divides in half to a radius of r = 3 cm.
[tex]V = \text{volume of a sphere}\\\\V = \frac{4}{3}\pi*r^3\\\\V \approx \frac{4}{3}*3.14*3^3\\\\V \approx 113.04 \ \text{ cm}^3\\\\[/tex]
This leads to
[tex]\text{density} = \frac{\text{mass}}{\text{volume}}\\\\D = \frac{M}{V}\\\\M = D*V\\\\M \approx 1.6*113.04\\\\M \approx 180.864\\\\M \approx 181 \text{ grams}\\\\[/tex]
