Answer:
Step-by-step explanation:
Given that a study found that the average stopping distance of a school bus traveling 50 mph was 264 feet.
Sample taken showed the following results
Since population std deviation is known and sample size is large, z test can be used.
(Left tailed test)
Mean difference = 
Std error = 
Z = test statistic = mean diff/std error
= 
p value = 0.00017
Since p < alpha our 0.05 we reject null hypothesis
There is evidence to show that mean is less than 264 feet
(Assumptions:
Sample are randomly drawn
Sample represents the population
They like action not comedy
Answer:B
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Verify each statement</u>
case A)
The statement is True
we know that
The measure of angle A is equal to the angle marked 
by corresponding angles
case B) ∠B and the angle marked 
are alternate exterior angles
The statement is False
Because, ∠B and the angle marked are corresponding angles
case C) because it is a vertical angle to the angle marked 
The statement is True
we know that
------> by vertical angles
case D) ∠B and ∠C are supplementary angles
The statement is False
we know that
---> the sum is less than 
case E)
The statement is True
we know that
and remember that
so
substitute
