1/25
think of it as 4/100
4 goes into 100 4 times
1/25+1/25+1/25+1/25=4/100
Answer:
the result would be 12
Step-by-step explanation:
(4 + 5) / 3 * 4 =9 / 3 * 4=3 * 4 = 12
Answer: (B)
Step-by-step explanation:
An independent sample test compares two sample means in order to determine the statistical significance of the difference between their population means.
The independent sample test would be the best hypothesis test for this study because:
1. There was a random samples of data from the population
2. There was no relationship between the subjects in each sample. That is;
- subjects in the first group were not also in the second group
- subjects in the first group did not influence subjects in the second group and vice versa.
3. There was independence of observations in this study. Each subject in each group was separately observed and each subject has a given fitness performance score.
4. There are values on both the dependent and independent variables.
- the dependent variable is FITNESS PERFORMANCE and for each subject, it is dependent on either the OLD EXERCISE PROGRAM or the NEW EXERCISE PROGRAM.
5. Our dependent variable her is a continuous variable as we see from the range of fitness scores. The lowest score is 19 and the highest score is 73. This shows that the variable is continuous. All the other scores fall in between.
6. Our independent variable is a categorical variable. Categorized into OLD EXERCISE PROGRAM and NEW EXERCISE PROGRAM.
Answer:
franchise fast-food restaurant located in the Northeast specializing in halfpound hamburgers, fish sandwiches, and chicken sandwiches. Soft drinks and French fries are
also available. The planning department of Bun-and-Run Inc. reports that the distribution of
daily sales for restaurants follows the normal distribution and that the population standard
deviation is $3,000. A sample of 40 showed the mean daily sales to be $20,000. Find the 95%
confidence interval for the population mean.
Answer:
<h2>24 miles</h2>
Step-by-step explanation:
If each lap is 1/8 of a mile, then we have to do 3x8 to get our answer.
8x3=24
So hence, Rex has to go 24 times around his block to ride his bike for 3 miles.
Thanks!
