Answer:
"They add up to 180 degrees, because they are a pair of supplementary angles"
Step-by-step explanation:
When parallel lines are cut by transversal, it creates vertical angles (opposite of each other) that are equal AND also supplementary angles (that are adjacent to each other and fall in one line). They add up to 180 degrees.
Looking at the figure, we see angle 1 and 2 fall in one line which is 180 degrees. Thus, angles 1 and 2 are supplementary, they add up to 180 degrees.
The correct choice is "They add up to 180 degrees, because they are a pair of supplementary angles"

Answer:
The probability that the sample mean exceeds $10,000 is 0.8078.
Step-by-step explanation:
The objective of the problem is obtained below:
From the given information, let X denotes the number of used cars which follows normal distribution with mean 10,325 and the standard deviation of 2,880 and sample size is 60 used cars. That is, u=10,325,δ = 2,880 and n=60
are used to estimate the probability that the sample mean exceeds 10,000.
