-5/-10=1/2. you can cancel the negative and the gcf of 5 and 10 is 2. so after you divide you get 1/2.

A data set consists of the values 2, 6, 3, and 1. If we consider this a population (all the values available), the variance isA.

Hoochie [10]

Answer: E. none of the above

Step-by-step explanation:

The given data values that represents the population:

2, 6, 3, and 1.

Number of values : n=4

Mean of the data values = $\dfrac{\text{Sum of values}}{\text{No. of values}}$

$\dfrac{2+6+3+1}{4}=\dfrac{12}{4}=3$

Sum of the squares of the difference between each values and the mean =

$(2-3)^2+(6-3)^2+(3-3)^2+(1-3)^2$

$=-1^2+3^2+0^2+(-2)^2$

$=1+9+0+4=14$

Now , Variance = (Sum of the squares of the difference between each values and the mean ) ÷ (n)

= (14) ÷ (4)= 3.5

Hence, the variance is 3.5.

Therefore , the correct answer is "E. none of the above".

If (s-3)^2=0, what is the value of (s+3) (s+5)?

Rufina [12.5K]

Here,

(s-3)²=0

→s-3=0

→s=3

Substituting s=3 in,

(s+3)(s+5)

=(3+3)(3+5)

=(6)(8)

=48
