Answer:
Their welders earn $50,000 annually.
Step-by-step explanation:
Given : 

n = 100

To Find : The ship building association wishes to find out whether their welders earn more or less than $50,000 annually.
Solution :

n = 100
Since n > 30
So we will use z test

Substitute the values


Refer the z table for p value
p value = 0.9599
α= 0.05
Since p value > α
So we accept the null hypothesis .
Hence their welders earn $50,000 annually.
The 2 angles given are vertical angles, which mean they are the same.
So we have: 3x +1 = 64
Subtract 1 from each side:
3x = 63
Divide both sides by 3:
X = 63 / 3
X = 21
The answer is A.
