Find the supplementary

weqwewe [10]

Answer:

70 degrees

Step-by-step explanation:

When two angles are supplementary, their measures must add up to 180 degrees. Therefore:

110+x=180

x=180-110

x=70

A survey asks a random sample of 2500 adults in California if they support an increase in the state sales tax from 7.50% to 7.75

Nadusha1986 [10]

Answer:

$E(Y) = 750$

Step-by-step explanation:

Given

Sample Size = 2500

Percentage = 30%

Required

Calculate Mean of Y

Mean or Expected Value is calculated as thus;

$E(Y) = np$

Where E(Y) represents the mean

n represents the sample size (or population)

p represents the success probability

$n = 2500 ; p = 30%$ %

$p = \frac{30}{100} = 0.3$

So,

$E(Y) = 2500 * 0.3$

$E(Y) = 750$

Hence, the mean value of Y is 750

-5(2b + 7) + b < -b - 11

Stells [14]

-5(2b+7) + b < -b - 11
-10b - 35 + b < -b - 11

- 10b + b - 35 < -b - 11

-9b - 35 < -b - 11

- 9b + b < - 11 + 35

-8b < 24

 $\frac{-8b}{-8} \ \textless \ \frac{24}{-8}$

b < -3

he graph shows the distribution of time (in hours) that teenagers spend playing video games per week. A graph titled Video games

Goshia [24]

"The graph shows the distribution of time (in hours) that teenagers spend playing video games per week. ", The statement that best describes the distribution is "The distribution is approximately Normal, with a mean of 14 hours and a standard deviation of 4" Option B.

This is further explained below.

<h3>What is Normal distribution?</h3>

Generally, Data closer to the mean tends to occur more often than data further from the mean, as shown by the normal distribution, also known as the Gaussian distribution. The normal distribution may be represented graphically as a "bell curve."

In conclusion, "the graph illustrates the distribution of the amount of time, in hours, that teens spend playing video games over the course of a week," The statement "The distribution is nearly normal, with a mean of 14 hours and a standard deviation of 4" is the one that gives the most accurate account of how the data was distributed.

Approximately​ ____% of the area under the normal curve is between mu minus sigma and mu plus sigmaμ− σ and μ+ σ.
