1 mile = 5,280 feet:
9 miles x 5280 feet per mile = 47,520 total feet per hour
1 hour = 3600 seconds.
Divide total feet by seconds per hour:
47,520 feet / 3600 seconds per hour = 13.2 feet per second.
Multiply feet per second by number of seconds for distance traveled:
13.2 feet per second x 15 seconds = 198 total feet.
Answer:
x = -3.5
Step-by-step explanation:
Simplifying
0.4x + 2.9 = 1.5
Reorder the terms:
2.9 + 0.4x = 1.5
Solving
2.9 + 0.4x = 1.5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2.9' to each side of the equation.
2.9 + -2.9 + 0.4x = 1.5 + -2.9
Combine like terms: 2.9 + -2.9 = 0.0
0.0 + 0.4x = 1.5 + -2.9
0.4x = 1.5 + -2.9
Combine like terms: 1.5 + -2.9 = -1.4
0.4x = -1.4
Divide each side by '0.4'.
x = -3.5
Simplifying
x = -3.5

Considering the p-value, the decision is described as follows:
Since the p-value is less than
, we reject
.
<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>
Depends on if the p-value is less or more than the significance level:
- If it is more, the null hypothesis is not rejected.
- If it is less, it is rejected.
In this problem, we have that:
- The p-value is of 0.0739.
- The significance level is of 0.1.
Hence:
Since the p-value is less than
, we reject
.
