A) The side length is 5 units since 5*5*5 = 125. You can guess and check to see which value multiplies with itself three times to get 125. Or you can take the cube root of 125 to get 5. You can type in 125^(1/3) to indicate you want the cube root of 125
b) The volume is 64 cubic units. Multiply the side length 4 by itself three times: 4*4*4 = 64.
Answer:
b
Step-by-step explanation:
I believe its b, because1.5 is 10 times 0.15
and 6.3 is 10 times 0.63
Answer:
( x + 2)(2x + 3)
Step-by-step explanation:
Answer:
The factors of 45 are: 1, 3, 5, 9, 15, 45
The factors of 76 are: 1, 2, 4, 19, 38, 76
Then the greatest common factor is 1.
Step-by-step explanation:
There are no common factors other than 1
Using the t-distribution, as we have the standard deviation for the sample, we have that the test statistic is given by:
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if there is no difference, that is:
At the alternative hypothesis, it is tested if there is a difference, that is:
<h3>What is the test statistic?</h3>
The test statistic is given by:
The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
In this problem, 
is tested at the null hypothesis, and the sample is: 20, -40, -40, 0, 20, - 60, -40, hence:
.
Hence, the test statistic is:
