2 cake recipes
Step-by-step explanation:
Count the number of Xs in between 1 1/8 and 1 5/8.
Answer:
And replacing we got:
Step-by-step explanation:
For this case we have the following info given:
represent the sample size selected
represent the population proportion
We want to find the standard error and we can use the distribution for the sample proportion and for this case since the sample size is large enough and we satisfy np>10 and n(1-p) >10 we have:
And the standard error is given;
And replacing we got:
A. X>3 due to multiplication of 11 fraction needs to be bigger than 1(4,5,6,....)
B. X<8 due to multiplication of 5 fraction needs to be less than 1(7,6,5,4,3,2,1,0,-1...)
C. X=2 since 2/x needs to equal to 1 you need the denominator to be 2 as well when mutiplying
I divide the numerator by the denominator
