The answer choices are
mean
median
mode
range

Mean: add all the numbers together and divide it by how many numbers there are

for plot 1:

2+3+3+4+6+9+9+9+11+11+12 = 79

There are a total of 11  numbers so divide 79 by 11

79 ÷ 11 = 7.18

for plot 2:

4+8+9+9+9+10+12+13+15+15+18 = 122

There are a total of 11  numbers so divide 122 by 11

122 ÷ 11 = 11.09

Median: Put the numbers in order from least to greatest and find the number in the exact middle

for plot 1:

2 3 3 4 6 9 9 9 11 11 12

3 3 4 6 9 9 9 11 11

    3 4 6 9 9 9 11

       4 6 9 9 9

          6 9 9

              9

for plot 2:

4 8 9 9 9 10 12 13 15 15 18

   8 9 9 9 10 12 13 15 15

       9 9 9 10 12 13 15

          9 9 10 12 13

              9 10 12

                  10

Mode: The number that appears the most

plot 1: there are three 9s

plot 2: there are three 9s

Range: Subtract biggest number by smallest number

plot 1:

12 - 1 = 11

plot 2:

18 - 4 = 14

The answer would be mode

Hope this helped!

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

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.
