Answer:
2.4 (6.2-x) > -4.5
I assume this is what you mean.
Answer:
23
Step-by-step explanation:
let the number be n then twice the number is 2n and 4 times the number is 4n
Then
2n = 4n - 46 ( subtract 4n from both sides )
- 2n = - 46 ( divide both sides by - 2 )
n = 23
The number is 23
Answer:
125
Step-by-step explanation:
put 9 where the n's are and sovle
(9-4)(3*9-2)
5*25
125
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:
See below.
Step-by-step explanation:
The law of sines is usually written as a / sin A = b / sin b == c / sin C where a is the side opposite angle A ,etc.
The first equation is true because it is obtained by cross multiplying
a / sin A = b / sin B, therefore b sin A = a sin B.
The second one is not true.
The third and fourth are both true.
