Answer:
From greatest to least: 5/8, 3/5, 0.07
Step-by-step explanation:
5/8 = 0.625
3/5 = 0.6
0.07 = 0.07
The number of folders and notebooks in the equation is given by 3 and 5 respectively.
<h3>How to find number of folders and notebooks?</h3>
let
- x = number of folders
- y = number of notebooks
The equation:
x + y = 8
0.50x + 1.0y = 6
From (1)
x = 8 - y
Substitute x = 8 - y into (2)
0.50(8 - y) + 1.0y = 6
4 - 0.50y + 1.0y = 6
4 + 0.40y = 6
4 - 6 = -0.40y
-2 = - 0.40y
y = -2 / 0.40
y = 5
Recall
x + y = 8
x + 5 = 8
x = 8 - 5
x = 3

B i think that because there’s no quantity
Answer:
Degree of freedom = 19
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 20
For a t-test hypothesis it was claimed that the population mean is greater than 89 second.
1) df
Df denotes the degree of freedom.
- The Degrees of Freedom refers to the number of values involved in the calculations that have the freedom to vary.
2) Degree of freedom = n - 1
where n is the sample size
Degree of freedom = 20 - 1 = 19
