Answer:
(A)The sample comes from a population of tires with 60,000 miles where 5% of tires are worn out.
Step-by-step explanation:
The tire manufacturer has a 60,000 mile warranty for tread life. To verify the authenticity of its claim, it picks a sample of 250 tires (out of the population of tires) that have been used for 60,000 miles.
Given the hypothesis:
: The proportion of tires that are worn out after 60,000 miles is equal to 0.05.
: The proportion of tires that are worn out after 60,000 miles is less than 0.05.
It is assumed that 5% of the tires in the sample are worn out and the hypothesis is formulated to prove or disprove this assumption.
Square root of area = (13y + 10) cm = length of each side of the square piece.
perimeter is
p = 4(13y + 10)
= 52y + 40 Answer
when y= 10 p = 560 answer
Option C is the correct one.
Answer:
213
Step-by-step explanation:
the equations for this is y=2x+13
just plug in x to find y
y=2(100)+13
y=213
