Answer:
Mean = 13 kilometer per second
Standard Deviation = 0.4082 kilometer per second
Step-by-step explanation:
We are given the following data set of rocket speed in kilometer per second in the question:
12.7, 13.4, 12.6, 13.3
Formula:
where are data points,
is the mean and n is the number of observations.
Deviations from mean = -0.3, 0.4, -0.4, 0.3
Sum of squares of differences =
0.09 + 0.16 + 0.16 + 0.09 = 0.5
Mean = 13 kilometer per second
Standard Deviation = 0.4082 kilometer per second
Answer:
363
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 92 and d = - 85 - (- 92) = - 85 + 92 = 7 , thus
= - 92 + (65 × 7) = - 92 + 455 = 363
