Sound City sells the ClearTone-400 satellite car radio. For this radio, historical sales records over the last 100 weeks show 4

Ksivusya [100]

Answer:

See below

Step-by-step explanation:

$\bf \mu(x)$ is the average

$\bf \mu(x)=\frac{4*0+33*1+39*2+12*3+8*4+4*5}{100}=\frac{199}{100}=1.99\;radios/week$

$\bf \sigma^2(x)$ is the variance

$\bf \sigma^2(x)=\frac{4*(0-1.99)^2+33*(1-1.99)^2+39*(2-1.99)^2+12*(3-1.99)^2+8*(4-1.99)^2+4*(5-1.99)^2}{100}=\frac{128.99}{100}=1.2899$

$\bf \sigma(x)$ is the standard deviation

$\bf \sigma(x)=\sqrt{variance}$

$\bf \sigma(x)=\sqrt{1.2899}=1.1357\;radios/week$

First chance you get the best marks

garri49 [273]

Answer:

<h2><em><u>First box and last box.</u></em></h2>

Step-by-step explanation:

<h2><em><u>It is the first box.</u></em></h2>

Distribute 7 to the first number

7 * -3/4 = -21/4

-21/4 = 5 -1/4

Distribute 7 to the second number

7 * -3

= -21

Put the numbers together

<h2><em><u>5 -1/4x -21 is the answer.</u></em></h2>

They separated the parenthesis.

So it is still 7 * -3/4

and

7*-3.

Hope this helps,
