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.
1) 22 + 22 + 22
2) 22 + 22 + 44
3) 22 + 44 + 44
4) 44 + 44 + 44
5) 44 + 44 + 88
6) 44 + 84 + 84
7) 84 + 84 + 84
8) 84 + 84 + 22
9) 84 + 22 + 22
10) 84 + 22 + 38
10 different total scores
Answer: The answer would be 60%
<span>the unit rate corresponds to the proportional relationship
shown in the graph is equivalent to the slope of the line. Which can be solve
using the formula:</span>
m = (
y1 – y2 )/ ( x1 – x2 )
m = (
0 – 9 ) / ( 0 – 6)
<span>m =
3/2</span>
-5x = - 7 because -6x plus x is -5x and use elimination to get rid of the -3y so you end up with -5x = -7
