I would say it’s B because out of ten it makes the mean 1 point higher
Answer: 10
Step-by-step explanation:
The formula to find the sample size is given by :-
Given : Significance level :
Critical z-value=
Margin of error : E=5
Standard deviation :
Now, the required sample size will be :_
Hence, the final sample required to be of 10 .
Answer:
x=4/9
Step-by-step explanation:
We first let 0.4 (4 being repeated) be x.
10x=4.4
10x-x=4.4-0.4
9x=4
x=4/9
This is an example of Pythagorean theorem. The equation for that is and so what you would do is substitute a with 80 and c with 100. That would make it .......anyways....the answer your looking for is 60ft.
Find the scale factor then multiply 3 by scale factor to find m. Scale factor is found by dividing larger side by smaller side. In this example, divide 10 by 6. (10 / 6 = 1.66666...) This means the larger triangle is 1.6x bigger than the smaller one. Then multiply 3 by 1.6666.. to find m. Hope this helps! :)
Btw your answer would be m = 5 but I didn’t want to give that away right away.
