Answer:
Rearrange the numbers to their like terms.
which is 2x-x=56-20.
x=36.
Using the p-value method, the decision rule is:
- |z| < 1.645: do not reject the null hypothesis.
- |z| > 1.645: reject the null hypothesis.
<h3>What is the relation between the p-value and 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 a two-tailed test, as we are testing if the mean is different of a value. For a significance level of 0.1, the critical value of z(when a p-value of 0.1 is obtained) is of |z| = 1.645, hence the decision rule is:
- |z| < 1.645: do not reject the null hypothesis.
- |z| > 1.645: reject the null hypothesis.

Answer:
15,300 + 18750 + 13,500 + 23,400 +19500 = 90,450
Step-by-step explanation:
divide all the numbers by 100, then multiplying by 3
The horizontal distance between the base of the ladder and the wall is: 11.8 foot
1/3 is the slope. When you rearrange the equation to be in y=mx+b form, you would subtract 9 and divide by three. x divided by 3 is equal to 1/3 x, so that would be the slope
