The volume of a sphere is equal to (4/3)pi*r^3
The volume of your sphere is then (4/3)*pi*r^3 = (4/3)*3.14159265*18^3 = 24429.024 cubic units. That is not one of the answer choices. The closest choice appears to be D.
Answer:
2x+y=−7
Step-by-step explanation:
Answer:
The required P value is 0.0901.
The critical value for the test statistic is 1.645.
Step-by-step explanation:
Consider the provided information.
The test statistic of z=1.34 is obtained when testing the claim that p> 0.1
It is given given that z=1.34 as the claim has greater than inequality so it is a right tailed test.
Part (A) P-value

From the Standard normal distribution table
.
Therefore,

Hence, the required P value is 0.0901.
Part (B) The critical value(s) is/are z=
It is given that the significance level is α=0.05
Using standard z value table we get the critical value for the test statistic is 1.645.
Hence, the critical value for the test statistic is 1.645.
We grapht hem
we see that the base is from (-2,2) and (6,2), 8 units long
the height will be from y=2 to y=8 or 6 units
so then, the area=1/2 times base times height=1/2 times 8 times 6=24 square units
Well, as far as I can tell, the mean (average) is the best representation of the data because there is no outlier (a number a lot higher or lower than the rest of the numbers that throws the data off).
