If the paint is 30% yellow, and you used 72 ounces of yellow, all you have to do is divide 72 by 30% to get the whole amount of ounces of paint made.
72 ÷ 0.30 = 240
In the last batch, you made 240 ounces of melon madness paint.
Answer:
The alternative hypothesis is
.
The critical value is 
Step-by-step explanation:
It is claimed that proportion in favor of proportion A is greater than 60%.
This means that at the null hypothesis, we test if the proportion is of at most 60%, that is:

At the alternative hypothesis, we test if the proportion is more than 60%, that is:

What is (are) the critical value?
The critical value is the value of Z with a p-value 1 subtracted by the standard significance level of 0.05, since we are testing if the mean is more than a value, so, looking at the z-table, 
Answer:
20
Step-by-step explanation:
so we know x+40=3x because opposite angles are congruent so if you solve it out you get x=20
Answer:
The top of the ladder is now at 10 ft.
Step-by-step explanation:
At the start, we have a height H=6, a length L=10 and a base B, that has to be calculated by the Pythagorean theorem:

The base is moved twice the distance the height moves up.
We called this distance x, so we have:

The new height (H+x) is

The base travels 2x=8, so the new base B' is 0.
This means that the ladder is all against the wall (L=H').
15% of 40 is 6
Hope this helps :D
