Answer:
The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
Find the margin of error for the confidence interval for the population mean with a 98% confidence level.
The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.
8 choose 3 = 8!/(3!*(8-3)!) = 8*7*6/(3*2) = 56
Answer:
4b^-1
Step-by-step explanation:
16a/4 = 4a
4a/a = 4
4/b = 4b^-1
Answer:
A & B
Step-by-step explanation:
A) V = pi×r²×h
= 3.142 × 8² × 5 = 1005.44 cm³
B) V = ⅓ × 18×16 × 12 = 1152 cm³
C) V = ½×5×3 × 7 = 52.5 cm³
Answer:
<h2>510</h2><h2 />
Step-by-step explanation:
30-22=8
22-14=8
14-6=8
then
→ the common difference r = 8
→ the first term = 6
THerefore, (accoriding to the standard explicit formula)
the 64th term = term 1 + (64 - 1)×r
= 6 + 63×8
= 510
