Answer:
A) 7
B) 32
C) 39
Step-by-step explanation:
Degree of freedom is a means of checking how many values that are free to vary, while using a statistical method.
a) since the experiment has a single factor with eight critical values. Therefore;
C - F = degree of freedom among the group variation
8 - 1 = 7
b) The degree of freedom can be calculated, if the number of data; Therefore, number of data is;
N = 8 × 5 = 40
Then the degree of freedom in determining within group variation,
N - C Therefore;
40 - 8 = 32
C) The degree of freedom in determining the total variation is,
N - 1
40 - 1 = 39
Answer:
B
Step-by-step explanation:
√256=16
√289=17
Answer:
18
Step-by-step explanation:
I am assuming you meant 8r-rs, in this case:
Plug in r=6 and s=5:
8(6)-(6)(5)
8*6 = 48 and -6*5= -30
Thus,
48-30= 18
Since both the expressions in x are equal to y then they are equal to each other, so
-2x + 3 = 13x - 4
-15x + 3 = -4
-15x = -7
x = 7/15
and y = -2(7/15) + 3 = 31/15 = 2 1/15
Answer:
120 degrees
Step-by-step explanation:
Attached is a screenshot.
y = 180 - 50 - 70 = 60.
x + y = 180, so x = 120
Remember to try to use parallel lines when you can
The second uses the same method, just the opposite side.
