Answer:
32°
Step-by-step explanation:
90 - 58 = 32
b = 32°
Answer:
The value of the test statistic z for this hypothesis test is -2.79
Step-by-step explanation:
Consider the provided information.
To calculate the test statistic use the formula:
Where, z is Test statistics, n is Sample size, p₀ = Null hypothesized value and 
= Observed proportion.
p₀ = 0.50
Thus 1-p₀= 0.50
42% responded that if they had a cell phone, thus 
The sample size is 305.
Substitute the respective values in the above formula.
Hence, the value of the test statistic z for this hypothesis test is -2.79
Your answer would be: w(w+2). Hope this helps :)

m - 3 = 3(b - 3)
m - 3 = 3b - 9
m + 6 = 3b
m/3 + 2 = b
5 years from now:
m + 5 = 2(b + 5)
m + 5 = 2b + 10
m - 5 = 2b
m/2 - 5/2 = b
combine:
m/3 + 2 = m/2 - 5/2
1. multiply by 6
2m + 12 = 3m - 15
2. add 15 - 2m to both sides
27 = m

The absolute value equation that represents the minimum and maximum scores is:
|x - 82| = 3.2.
<h3>What is the absolute value function?</h3>
The absolute value function is defined by:
It measures the distance of a point x to the origin.
For this problem, the distance between the minimum and the maximum scores and the mean is of 3.2, that is, the difference between these scores x and the mean of 82 is of 3.2, hence the absolute value equation that represents this situation is given by:
|x - 82| = 3.2.
