4 pairs of pants for $18.
Divide price by quantity to get the cost of 1 pair of pants:
18 / 4 = 4.50 per pair.
Divide 27 by 4.50 to find number of pairs:
27 / 4.5 = 6
6 pairs of pants can be cleaned for $27.
Answer:
There is not enough evidence to support the executive's claim that the percentage is actually different from the reported percentage of 26%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 100
p = 26% = 0.26
Alpha, α = 0.01
First, we design the null and the alternate hypothesis
This is a two-tailed test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.040267
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Thus, there is not enough evidence to support the executive's claim that the percentage is actually different from the reported percentage of 26%.
In the pattern, the values are increasing by 22 each time so for the 117th term you take 57 + 22 = 79
So, 117= 79
Answer:
The correct answer is choice D.
Step-by-step explanation:
Since the parabola opens sideways, that means the function will feature and not , so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of is positive. Using all of this information, you'll find that the correct answer is D: .
