When individuals in a sample of 150 were asked whether or not they supported capital punishment, the following information was o
Roman55 [17]

Answer:

Option C.

Step-by-step explanation:

Given information:

Sample size = 150

Number of Opinions = 3 (Yes, No, No Opinion)

Yes = 40

No = 60

No opinion = 50

We need to find the expected frequency for each group.

Expected frequency for each group is the quotient of sample size and number of opinions.

\text{Expected frequency for each group}=\dfrac{\text{Sample size}}{\text{Number of Opinions}}

\text{Expected frequency for each group}=\dfrac{150}{3}

\text{Expected frequency for each group}=50

Therefore, the correct option is C.

What is the result of isolating y^2 in the equation below (x-2)^2+y^2=64?
natta225 [31]

What is the result of isolating y^2 in the equation below (x-2)^2+y^2=64?

Solution:

We want to isolate y^{2} from the equation (x-2)^{2} +y^{2} =64

To isolate y^{2}, we must try to get y^{2} alone

So, We must subtract (x-2)^{2} from both sides

(x-2)^{2}-(x-2)^{2}  +y^{2} =64-(x-2)^{2}

0 +y^{2} =64-(x-2)^{2}

y^{2} =64-(x^{2}-4x+4)

Distributing '-' inside parenthesis

y^{2} =64-x^{2} +4x -4

y^{2} =60-x^{2} +4x
