I believe the answer is V = 216^3
Answer:
The 98% confidence interval for the mean number of car accidents per month at a specific intersection is between 18.58 and 65.42 accidents per month.
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 16 - 1 = 15
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 15 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.602
The margin of error is:
M = T*s = 2.602*9 = 23.42
In which s is the standard deviation of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 42 - 23.42 = 18.58 accidents per month.
The upper end of the interval is the sample mean added to M. So it is 42 + 23.42 = 65.42 accidents per month.
The 98% confidence interval for the mean number of car accidents per month at a specific intersection is between 18.58 and 65.42 accidents per month.
The outer diameter is 1/36*2+1/6
= 1/3 inches
Answer:
27
Step-by-step explanation:
on one face you see 3 x 3 (top face)
3 x 3 = 9
and if you look at another side (right one is what im looking at) you will see 3 x 3 again so that means this will be equal to 3 cubed (3^3) or 3 x 3 x 3
if you do 9 x 3
9 x 3 = 27
that equals the volume of the cube
27 units cubed
9514 1404 393
Answer:
-12, -21
Step-by-step explanation:
Let x represent the first number. Then the second is x-9. The other relation is ...
4x = 2(x-9) -6
2x = -24 . . . . . subtract 2x, simplify
x = -12
x-9 = -21
The first number is -12; the second number is -21.
