Answer: 
Step-by-step explanation:
The confidence interval estimate for the population mean is given by :-
, where
is the sample mean and ME is the margin of error.
Given : Sample mean: 
The margin of error for a 98% confidence interval estimate for the population mean using the Student's t-distribution : 
Now, the confidence interval estimate for the population mean will be :-

Hence, the 98% confidence interval estimate for the population mean using the Student's t-distribution = 
12*5*4.25=255 cubic in (total vol.)
.25*.25*.25=1/64 (vol. of small cube)
255/(1/64)=16,320 cubes
Answer:
x-2
The choose (1)
Step-by-step explanation:
(x³-3x²+3x-2)÷(x²-x+1)
(x-2)(x²-x+1) ÷ (x²-x+1)
Delete (x²-x+1)
so = (x-2)
T=-9
Negative plus negative is positive.
Hope that helped :))
Your x will be -60 because you subtract 9x from 8x that equal-1 and you divide it by 60 because if you add 42+18 it will be 60 so you divide 60 by -1 and the answer will be -60
