If the 3’s were exponents then... i got 50r3
how i solved:
39r3 + 11r3 + 45s3 - 5s3 - 40s3
50r3 + 40s3 - 40s3
50r3 + 0
= 50r3
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
Simple, all you want to do is subtract. 7-2=5; and denominators are not subtracted thus it would be 5/8. And that is the simplest form already 5/8.
The slope is 4/3 because rise over run (if u have heard of that expression)
Answer:
Max vol = 2 cubic metres
Step-by-step explanation:
Given that from a square piece of cardboard paper of area size 9 m2 , squares of the same size are cut off from each corner of the paper.
Side of the square = 3m
If squares are to be cut from the corners of the cardboard we have the dimensions of the box as
3-2x, 3-2x and x.
Hence x can never be greater than or equal to 1.5
V(x) = Volume = 
We use derivative test to find the maxima
Equate I derivative to 0
If x= 3/2 box will have 0 volume
So this is ignored
V"(1/2) <0
So maximum when x =1/2
Maximum volume
=
cubic metres
