The reason why the number of failures and successes in two population proportions must be up to 10 is because it is important to have many of samples from both populations.

<h3>What is a Confidence Interval?
</h3>

This refers to the probability displayed that a parameter will exist between a pair of values around the mean.

It measures the extent to which one can be certain or uncertain about ones sampling method. Confidence Intervals are usually constructed using levels of 95% or 99%.

Which of the following shapes have an area of 48 square feet? Select all that apply.
yKpoI14uk [10]
I think 2,3,4 or B,C,D would be correct.

The area of a triangle is (b•h)/2
And the area of a rectangle and parallelogram would just be b•h

1) 8(6) = 48/2 =24

2) 9(10 2/3) = 96/2 =48

3) 19.2(2.5) = 48

4) 16(3) = 48

Hope this is right and hope it helps. Have a good day
