Answer:
A
Step-by-step explanation:
100fps=68.182mph
68.182/3.8=17.94
Answer:
The mean of the samples is 21
Step-by-step explanation:
Mean is defined as the average sum of numbers i.e total sum of given numbers divided by the total number.
Given the randomly selected numbers as shown;
7, 100, 1, 3, 7, 10, 15, 12, 17, 38
Total sum of numbers = 7+ 100 + 1 + 3 + 7 + 10 + 15 + 12 + 17 + 38
= 210
Total numbers given = 10
Mean = 210/10
Mean = 21
F(1) = 160 is given to us. We'll use it to find f(2)
f(n+1) = -2*f(n)
f(1+1) = -2*f(1) ... replace every n with 1
f(1+1) = -2*160 ... replace f(1) with 160
f(2) = -320
Now use f(2) to find f(3)
f(n+1) = -2*f(n)
f(2+1) = -2*f(2) ... replace every n with 2
f(3) = -2*(-320) ... replace f(2) with -320
f(3) = 640
Finally, use f(3) to find f(4)
f(n+1) = -2*f(n)
f(3+1) = -2*f(3) ... replace every n with 3
f(4) = -2*640 ... replace f(3) with 640
f(4) = -1280
Final Answer: -1280
