The data (1.5.8.5.1) represent a random sample of the number of days absent from school for five students at Monta Vista High. F

lianna [129]

Answer:

$\bar X = \frac{1+5+8+5+1}{5}= \frac{20}{5}= 4$

$\sigma= \sqrt{\frac{(1-4)^2 +(5-4)^2 +(8-4)^2 +(5-4)^2 +(1-4)^2}{5}} =\sqrt{\frac{36}{5}}= 2.68$

And based on this the best answer would be:

a. mean = 4; standard deviation = 2.68

Step-by-step explanation:

For this case we have the following data given:

1,5,8,5,1

We can find the sample mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X = \frac{1+5+8+5+1}{5}= \frac{20}{5}= 4$

And for the deviation (assuming that the correct approximation is the deviation for a population) we can calculate the deviation with the following formula:

$\sigma = \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n}}$

And replacing we got:

$\sigma= \sqrt{\frac{(1-4)^2 +(5-4)^2 +(8-4)^2 +(5-4)^2 +(1-4)^2}{5}} =\sqrt{\frac{36}{5}}= 2.68$

And based on this the best answer would be:

a. mean = 4; standard deviation = 2.68

How much we need for start-up supplies . . . . . $25

AFTER start-up supplies we want to have . . . $70

Total amount we need to get started . . . (25 + 70) = $95

Number of people contributing . . . (me + 4) = 5

<em>Amount each person needs to kick in</em> . . . (95/5) = <em>$19</em>

If f(x) = 3x + 10x and g(x) = 2x – 4, find (f – g)(x).

Neko [114]

Answer:

(f-g)(x) = 11x+4

Step-by-step explanation:

(f-g)(x) = f(x) - g(x)

This means we have

3x+10x-(2x-4)

This gives us

3x+10x-2x--4

3x+10x-2x+4

13x-2x+4

11x+4
