The following data values represent a population what is the variance of the values 17, 5 ,11, 1,11
marin [14]
1) from smaller to higher:
1,5,11,11,17

2) find the mean
<span>1 + 5 + 11 + 11 + 17 = </span><span>45
</span>mean = 45/5 = 9

Variance = Σ(x- mean)²/(N-1)
[(1-9)² + (5-9)²+(11-9)² + (11-9)²+ (17-9)² ]'(5-1) =  38

Variance = 38

Which equation is shown on the graph?
Blizzard [7]
Hello there! As far as we can see, the y-intercept is 2. Going up 2 helps move the line up by 2. We can go ahead and eliminate C, because that equation only goes up one, and D, because we don't go down any. We have the points (1, 3) and (2, 4). We add the x-value and we can see that 1 + 2 is 3 and 2 + 2 is 4. The only equation that fits the line at all is A. Therefore, the answer is A.

frez [133]

Answer:

8x-40y\geq 600 and x>0,y>0

Step-by-step explanation:

The number of people is x and the number of hours they are present in the space is y.

Per person entry cost is $8.

Per hour cost of rent is $40.

They plan to earn a minimum of $600.

Donations by all the people entering the space is 8x

Total cost of renting the space is 40y which will be subtracted from the total amount of donations.

The inequality that represents the situation is 8x-40y\geq 600 and x>0,y>0.

A certain store sells only T-shirts. Let the random variable X represent the number of T-shirts bought from the store on any day
faltersainse [42]

Answer:

(a)\ \mu_y = 1125

(b)\ \sigma_y = 300

Step-by-step explanation:

Given

\mu_x = 75 -- Mean of T-shirts

\sigma_x = 20 -- Standard deviation of T-shirts

Rate = \$ 15

Solving (a): The mean of the revenue (\mu_y)

To solve this, we use:

\mu_y = Rate * \mu_x\\

This gives:

\mu_y = 15 * 75

\mu_y = 1125

Solving (b): The standard deviation of the revenue (\sigma_y)

To solve this, we use:

\sigma_y = \sqrt{Rate^2 * \sigma_2^2}

This gives:

\sigma_y = \sqrt{15^2 * 20^2}

\sigma_y = \sqrt{90000}

\sigma_y = 300
