Step-by-step explanation:
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:
The perimeter of the rectangle is calculated using the following rule:
perimeter = 2(length + width)
We are given that:
perimeter = 74 meters ............> given I
length is 5 more that width.
This means that:
length = width + 5 ..........> given II
Substitute with given I and given II to get the width of the rectangle as follows:
74 = 2(width+5+width)
74/2 = 2*width + 5
37 = 2*width + 5
37-5 = 2*width
32 = 2*width
width = 32/2 = 16 meters
If you want to get the length, we can use given II as follows:
length = width + 5
length = 16 + 5 = 21 meters
Based on the above calculations:
width of rectangle = 16 meters
length of rectangle = 21 meters
