I think the correct answer would be B. The graph in the attached image would most likely be described as a bimodal symmetric. A bimodal graph would be a graph which has two peaks. From the image, we have 3 peaks so it should be a multimodal but it is not in the choices the closest would be a bimodal one. Each group of the peak shows a symmetrical distribution since the left side and the right side are almost mirrors of each other which is seen for all the three peaks. So, the graph should be a bimodal symmetric distribution.

The school that Beth goes to is selling tickets to a spring musical. On the first day of ticket sales

Maru [420]

Answer:

Student tickets are $14 each

Senior Citizen tickets are $4 each

Step-by-step explanation:

Let C be the price of a Senior Citizen ticket, and S be the price of a Student ticket.

We learn that on the first day:

2C + 7S = $106

On the second day:

3C + 14S = $208

We have two equations and two unknowns. Rearrange either equation to isolate either C or S and use that value in the other equation.

I'll choose 2C + 7S = $106

C = ($106 - 7S)/2

Use this in the other equation:

3C + 14S = $208

3(($106 - 7S)/2) + 14S = $208

($318 - 21S)/2 + 14S = $208

$159 - 10.5S + 14S = $208

3.5S = $49

S = $14 Student tickets are $14 each

Use this answer in either equation to find C:

C = ($106 - 7S)/2

C = ($106 - 7($14))/2

C = $4 Senior Citizen tickets are $4 each

====

Check to see if these values work in the original equations:

1. 2C + 7S = $106

2($4) + 7($14) = $106 ?

$8 + $98 = $106 ? YES

2. 3C + 14S = $208

3($4) + 14($14) = $208 ?

$12 + $196 = $208 ? YES

Between 10 P.M. and 7:54 A.M., the water level in a swimming pool decreased by 11/40 . Assuming that the water level decreased

xxMikexx [17]

Answer:

It approximately dropped 0.027777 per hour.

Step-by-step explanation:

First, we calculate the decrease.

Decrease = 11/40 = 0.275

Then, we calculate the time interval.

From 10 pm to 7:54 hours will be 9.54 hours

Time interval= (9 + 54/60) hours

Time interval=9.9 hours

Finally, we calculate how much it dropped each hour

0.275/9.9 ≈ 0.027777

So it approximately dropped 0.027777 per hour.
