Answer:

Step-by-step explanation:

Given

See attachment for chart

Required

Number of off days

To do this, we simply calculate the expected value of the chart.

This is calculated as:

$E(x) = \sum x * f$

Where

x = days

f = chances

So, we have:

$E(x) = 0* 0.3 + 1 *0.2 + 2 * 0.25 + 3 * 0.2 + 4 * 0.02 + 5 * 0.01 + 6 * 0.01 + 7 * 0.01$

$E(x) = 1.56$

$E(x) \approx 2$

Solve for x. 15x + 6 = 10x + 21 x = -5 x = 5 x = 3 x = 5

klio [65]

Move all the x terms to one side and solve for x. 15x-10x=21-6 : 5x/5=15/5 : x=3

Use the frequency table to find the mean number of working TV sets in students' homes. (picture attached)

LenaWriter [7]

The correct option is : 2

Explanation

For finding the mean number of working TV sets, we need to divide the total number of TV sets by the total frequency.

Now for finding the total number of TV sets, first we will multiply each number of TV sets by it's frequency and then sum up all the results.

So, the total number of TV sets

$=(0*1)+(1*8)+(2*9)+(3*4)+(4*3) \\\\ =0+8+18+12+12=50$

and total frequency $=1+8+9+4+3= 25$

Thus, the mean number of working TV sets $= \frac{50}{25}=2$
