Joe jumped the farthest at 6 1/4 (6 ft 3 in)
Chelsey jumped the shortest ar 4 1/5 (4 ft 2.4 in)
6-4=2
3-2.4=.6
the difference is: 2 ft and 0.6 in
Answer:
49 eggs.
Step-by-step explanation:
The formula for Margin of Error =
z × standard deviation/√number of samples
z = z score of 98% confidence interval = 2.326
Margin of Error = Half a day = 1/2day = 0.5 day
Standard deviation = 1.5 days
Number of samples = number of eggs he needs to sample = unknown.
Imputing these above values into the formula
Margin of Error = z × standard deviation/√number of samples
0.5 = 2.326 × 1.5/√n
Cross Multiply
0.5 × √n = 2.326 × 1.5
√n = 2.326 × 1.5/0.5
√n = 3.489/0.5
√n = 6.978
Square both sides
(√n)² = 6.978²
n = 48.692484
n ≈ Approximately to the nearest whole number = 49
Therefore, the number of eggs he needs to sample to create the desired interval is approximately to the nearest whole number 49 eggs
V=B*h
To double the volume , we have to double the height
then V2=B*2h=2*V
Answer:
There were 45 pies sold in all.
Step-by-step explanation:
10 + 15 = 25
25 + 20 = 45
Total = 100.00 * (1 + .06/12)^12*20
Total = 100.00 * (1.005)^240
Total = 100.00 *
