Answer:
All real numbers or (negative infinity, positive infinity)
Step-by-step explanation:
The equation given is a parabola. A parabola has infinite values of x inputs that produce an infinite amount of y outputs. All values of x produce an output, so any number of x would work.
Step-by-step explanation:
First, find the degrees of freedom:
df = n − 1
df = 49
To find the p-value manually, use a t-score table. Find the row corresponding to 49 degrees of freedom. Then find the α column that corresponds to a t-score of 1.421. You'll find it's between α = 0.10 (t = 1.299) and α = 0.05 (t = 1.677). Interpolating, we get an approximate p-value of 0.084. For a more accurate answer, you'll need to use a calculator.
Answer: 1/2 of a sheet
Step-by-step explanation:
2 sheets divided by 4 people
2/4
Simplify to 1/2
4.5 x 10 = 45
4.5 x 2 = 9
9 + 45 = 54
54 + 4.5 = 58.5
1 + 2 + 10 = 13 weeks
13.5 weeks = 3 months
2 months and 4 weeks
