Just substitute each number into the expression:
5(5) - 6(3) + 20(1/4)/4(3)(1/4) = 25 - 18 + 5/3 = 7 + 5/3 = 26/3 or 8 and 2/3.
How did who figure out what answer?
Answer: b. 30%
Step-by-step explanation:
- A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.
i.e. 
Given: mean = 
Variance = 
Now, 
in percent , 
Hence, correct option is b. 30%.
4.6x^2+3.2-4x+2.7x^2-x=4.6x^2+3.2x+-4x+2.7x^2+-xCombine like terms:4.6x^2+3.2x+-4x+2.7x^2+-x=(4.6x^2+2.7x^2)+(3.2x+-4x+-x)=7.3x^2+-1.8xAnswer:7.3x^2-1.8x
Answer:
D or 3
Step-by-step explanation:
The equation you are saying is
-x = x-6
If you move both x's to one side, you get
-2x = -6
From this, you can simplify by dividing by -2
x=3, or D.
