A: 8*9= 72 or 72 because it is the lowest multiple of 8 and 9
B: euclidean theorem (35,63) (35,28) (7,28) (7,0) gcf= 7 or 7 because 7 is the biggest number that goes into both numbers.
C: 7(5+9) or 35 is a factored into 7 and 5 and 63 is factored into 7 and 9 and 9 is factored into 3 and 3
Answer:
Step-by-step explanation:
1.) mean is 4 1,2,3,5,6,7
2.) Four students won 12, 13, 14, 15, 16, or 17 prizes.
A total of 10 prizes were won by all the students.
3.)don't know number 3
The value of alpha is 0.26, assuming a confidence level of 74%.
<h3>What is the margin of error?</h3>
The significance level α is the probability of making the wrong decision when the null hypothesis is true.
Alpha levels which is also called as significance levels are used in hypothesis tests.
Given
When finding the margin of error for the mean of a normally distributed population from a sample.
The confidence interval = 74% = 0.74.
The value of the alpha is given by;
Substitute all the values in the formula
Hence, the value of alpha is 0.26, assuming a confidence level of 74%.

This shows that 76 cookies will be made with the total pounds of cookies
<h3>Ratio and proportion</h3>
Fractions are written as a ratio of two integers. Given the following parameters
Total pounds of cookies made = 4 3/4 pounds
Total pounds of cookies made = 19/4 pounds
If he uses 1/16 pound of dough for each cookie, the total amount of cookies made is given;
Number of cookies = 19/4 ÷ 1/16
Number of cookies = 19/4 * 16/1
Number of cookies = 19 * 4
Number of cookies = 76
This shows that 76 cookies will be made with the total pounds of cookies
