Lin solved the equation

Alekssandra [29.7K]

Answer: x=1/2

she was wrong, it's supposed to be

Step-by-step explanation: 8(x−3)+7=2x(4−17)

Step 1: Simplify both sides of the equation.

8(x−3)+7=2x(4−17)

(8)(x)+(8)(−3)+7=2x(4−17)(Distribute)

8x+−24+7=−26x

(8x)+(−24+7)=−26x(Combine Like Terms)

8x+−17=−26x

8x−17=−26x

Step 2: Add 26x to both sides.

8x−17+26x=−26x+26x

34x−17=0

Step 3: Add 17 to both sides.

34x−17+17=0+17

34x=17

Step 4: Divide both sides by 34.

34x/34=17/34 x=1/2

Answer:

μ =2.23

$\sigma_x^2= 1.49$

$\sigma_x=1.22$

Step-by-step explanation:

Radio(x) weeks P(x)

0 5 5/100 = 0.05

1 27 27/100=0.27

2 27 27/100 = 0.27

3 27 27/100 = 0.27

4 9 9/100=0.09

5 5 5/100=0.05

We know that

Mean ,μ

$\mu =\sum x.P(x)$

μ = 0 x 0.05 + 1 x 0.27 + 2 x 0.27 + 3 x 0.27 + 4 x 0 .09 + 5 x 0.05

μ =2.23

$\sigma_x^2= \sum x^2\times P(x)-(\sum x.P(x))^2$

$\sigma_x^2= 0^2\times 0.05+ 1^2\times 0.27+ 2^2\times 0.27+ 3^2\times 0.27+ 4^2\times 0.09+5^2\times 0.05-2.23^2$

$\sigma_x^2= 1.49$

$\sigma_x= \sqrt{\sigma_x^2}$

$\sigma_x=1.22$
