Answer:
The margin of error for a 90% confidence interval is 16.4
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 25
Standard deviation = 50

Margin of error =

Putting the values, we get,

Thus, the margin of error for a 90% confidence interval is 16.4
Answer:
The answer is 336cm
Step-by-step explanation:
Multiply 24 & 14
We take the value of F in the inequality by taking the inequalities in group. Let the first group be:
(1) -20 ≤ 59(F - 32)
Then, the second group would be,
(2) 59(F - 32) ≤ - 15
Calculating for the values of F,
(1) -20 ≤ 59F - 1888
1888 - 20 ≤ 59F
1868 ≤ 59F
F ≥ 31.66
(2) (59)(F - 32) ≤ - 15
59F - 1888 ≤ -15
59F ≤ 1873
F ≤ 31.75
The values of F are therefore,
31.66 ≤ F ≤ 31.75
Answer && Step-by-step explanation:
7 yards == 4/4
by simple arithmetic remove 3/4 from 7 until you can no longer obtain 3/4 from it
7 => 6*1/4
6*1/4=>5*2/4
5*2/4=>4*3/4
4*3/4=>4
4=> 3*1/4
3*1/4=>2*2/4
2*2/4=>1*3/4
1*3/4=>1
1=>1/4
1/4 remains and 9 bows were made
