Problem 3: i'm not too sure sorry :(
Answer:
The answer to your question is the second and the last choices.
Step-by-step explanation:
Process
1.- In the first step v₀t subtract d and the result is
d - v₀t = at²/2
2.- In the second step, 2 multiply (d - v₀t), and the result is
2(d - v₀t) = at²
3.- In the third step t² divide 2(d - v₀t), and the result is
a = [2(d - v₀t)]/t²
Answer:
Degree of freedom is 6.
Step-by-step explanation:
A sample of seven infants is randomly selected and their weights at birth are recorded.
Given, Population mean = 6.6 pounds
Sample size = n = 7
Degree of freedom = n - 1
= 7 - 1
= 6
Degree of freedom is 6.
