Answer:
It's A. 28 degrees
Step-by-step explanation:
First, you determine the angle measure directly below x. That is a straight line, so it measures 180 degrees. You can add 38 and 90 degrees, and then subtract from 180 to get the last angle measure. This gives you 52. The right 3 angles measure 90 degrees, because they are on the opposite side of a right angle marker. You can add 10 and 52 and then subtract from 90 to get the missing x value, 28.
Answer: There is convincing evidence at the the significance level that the DMV's claim is incorrect.
Step-by-step explanation:
Since we have given that
Hypothesis:

Probability of teens pass their drivers test on the first attempt = 60% = 0.60
Number of teens = 125
Number of them passed the tests on their first try = 86

So, the value of test statistic would be

At α = 0.05% level of significance, critical value = 1.645
Since 1.645 < 2.01
So, we will reject the null hypothesis.
Hence, there is convincing evidence at the the significance level that the DMV's claim is incorrect.
Rational, or integer. I am not sure sorry
-15m -30 = -12m +6
3m = 36
m= 36/3 =12
30 x 0.05 = $1.5 is the answer
