What could you do to describe the following data, showing temperatures for the week? (check all that apply.) mon - 65° tues - 67° wed - 66° thur - 70° fri - 72° sat - 68° sun - 69° construct a line graph. find the mean, median, mode, and range. construct a stem-and-leaf plot. survey people about the weather.

Hi!

In this question i can only help with the 2nd part!

Part B:

Mean:

65 + 67 + 66 + 70 + 72 + 68 + 69 / 7

477 / 7

= 68.142 = 68

Median:

65, 66, 67, 68, 69, 70, 72

Median = 68

Mode:

There is no mode

Range:

65, 66, 67, 68, 69, 70, 72

72 - 65 = 7

Range = 7

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
