Answer:
If we examine a sample of tires used for 60,000 miles and determine the proportion that are worn out, how likely is that proportion to be 3.6% or less?
Step-by-step explanation:
First of all, when you want to contrast two hypothesis you need a confidence level p% without which the comparison makes no sense.
In this case, you want to refuse the null hypothesis (the average is 5%) with an alternative one (the average is less than 5%).
You propose a new average (3.6%) based on the evidence.
You cannot prove that the average is actually 3.6%, <em>but if you somehow determine that the probability the average is greater than 3.6% is lower than 100% minus your confidence level p% ,then you can refute the null hypothesis and accept the alternative one as new average.
</em>
So, from the possible choices, the one that fits the best is

Answer:
x = 26
Step-by-step explanation:
1 / 3 (x - 2) = 1 / 5 (x + 4) + 2
1/3x - 2/3 = 1/5x + 4/5 + 2
1/3x - 1/5x = 4/5 + 2/3 + 2
(5x - 3x)/15 = (12 + 10 + 30) / 15
2x / 15 = 52 / 15
2x = 52
x = 52 / 2
x = 26
Answer:
A. 57.2
Step-by-step explanation:
Given: Nelly runs = 10-mile race in 88 minutes. At the same rate but 6.5-mile race
To find: How long it would take him to run a 6.5-mile race
Solution: To calculate the how long;
<u>How to calculate running pace</u>
- Divide your run time by your distance
- If you ran 3 miles in 30 minutes: 30 min ÷ 3 mi = 10 minutes per mile pace
<u>How to calculate run distance</u>
- Divide your running time by your pace
- If your pace is 8 minutes per mile and you ran for 32 minutes: 32 min ÷ 8 min per mi = 4 miles
<u>How to calculate run time</u>
- Multiply your pace by your distance
- If your pace is 9.5 minutes per mile and you ran 3 miles: 9.5 min per mi × 3 mi = 28.5 minutes = 28 minutes, 30 seconds
<u>How to calculate running speed</u>
- Divide your run distance by your run time
- If you ran 2.5 miles and you ran for 20 minutes:
2.5 mi ÷ 20 min = 0.125 miles per minute
Answer:
The equation of the line would be y = 4/9x
Step-by-step explanation:
In order to find the equation, we first need to find the slope. We can do this by using the slope equation with the points.
m(slope) = (y2 - y1)/(x2 - x1)
m = (9 - 0)/(4 - 0)
m = 9/4
Now that we have this, we can use point-slope form along with one of the points to get the equation.
y - y1 = m(x -x1)
y - 0 = 4/9(x - 0)
y = 4/9x
