Jack would need to buy 2 bags of sand.
To find the answer you first have to find the volume of the rectangular box which can be found using the formula length times width times height (remember that the numbers have to have the same unit so it would look like 3 times .5 times .2 if you convert them all the feet). the volume of the box is equal to .3
Then you could set the volume of the box equal to .15x to find how many boxes he would need. The formula would be .15x=.3
Divide by .15 to get x alone and you get 2 for the answer.
The correct answer is 12
Set up a ratio and then solve. See paper attached. (:
Answer:

Step-by-step explanation:
The Pythagorean Theorem is used to find a missing side length in a right triangle, and the formula
is used to find the missing side, assuming a and b are legs, while c is the hypotenuse.
Answer:0.1446
Step-by-step explanation:
Let p be the population proportion of adults say that cloning of humans should be allowed.
As per given , the appropriate set of hypothesis would be :-

Since
is left-tailed and sample size is large(n=1012) , so we perform left-tailed z-test.
Given : The test statistic for this test is -1.06.
P-value for left tailed test,
P(z<-1.06)=1-P(z<1.06) [∵P(Z<-z)=1-P(Z<z]
=
(Using z-value table.)
Hence, the p-value for this test statistic= 0.1446
