Answer:
StartFraction 8 Over 25
Step-by-step explanation:
What is the product of StartFraction 4 Over 5 EndFraction times two-fifths?
Mathematically =
StartFraction 4 Over 5 EndFraction = 4/5
Two- fifths = 2/5
Hence,
The product of StartFraction 4 Over 5 EndFraction times two-fifths
= 4/5 × 2/5
= 8/25
The correct option =
StartFraction 8 Over 25 EndFraction
Answer:
The alternative hypothesis being tested in this example is that the tire life is of more than 60,000 miles, that is:

Step-by-step explanation:
A tire manufacturer has a 60,000 mile warranty for tread life. The company wants to make sure the average tire lasts longer than 60,000 miles.
At the null hypothesis, we test if the tire life is of at most 60,000 miles, that is:

At the alternative hypothesis, we test if the tire life is of more than 60,000 miles, that is:

Remember
a²-b²=(a-b)(a+b)
8x²-50y²
2(4x²-25y²)
(2)([2x]²-[5y]²)
2(2x-5y)(2x+5y)
