Answer:
x = the number
Step-by-step explanation:
15.) 2x + 9 = 25
16.) 3x - 6 = 21
17.) 7x = 12 + 3x
18.) 4x = 18 + x
19.) 2x + 24 = 8x
20.) 30 - x = 4x

Step-by-step explanation:
Answer:
d = 2.2
Step-by-step explanation:
Using the distance formula, you would plug in the numbers into the equation. d = √(5 - 3)^2 + ( -3 + 2)^2. So (5 - 3) is 2, and (-3 + 2) is -1. Then square both of the answers, and the equation becomes, d = √4 + 1. And that equals 5, so then you would find the square root, which would be approximately 2.2
Answer with Step-by-step explanation:
Since we have given that
Mean = 150
Standard deviation = 8.8
An admissions officer at a large graduate school believes the mean is less than 150.
a)Determine the null and alternative hypotheses.
So, hypothesis :
b)Explain what it would mean to make a Type I Error.
As we know that Type 1 error are those errors in which null hypothesis is supposed to be rejected but not get rejected.
So, here, mean is not less than 150 but in actual it is less than 150.
c)Explain what it would mean to make a Type II Error.
As we know that Type II error are those errors in which null hypothesis is not supposed to be rejected but it gets rejected.
So, mean is less than 150 but actually it is not less than 150.
