the answer is b 18 because you add all three together and dived by 3
3x8= $24 for a box of paper. So, D) 24x12 is the answer. For 12 boxes it would cost $288.

Answer:
Area = 12
Step-by-step explanation:
The perpendicular bisector of the triangle going from upper left to the middle marks the height of the triangle. It's area is found from the standard formula.
Area = b * h / 2
b = 2 + 2 = 4
h = 8
Area = 1/2 * 4 * 8
Area = 1/2 * 32
Area = 16
The smaller triangle is found from all the twos.
b = 2 + 2 same as the larger triangle
h = 2
Area = 1/2 2 * 4
Area = 1/2 8
Area = 4
Total Area = 4 + 16
Total Area = 20
Mean is the average of the data set, which is found by adding all values together and then dividing that sum by the number of data values.
Median is the middle number of the data set, and can be found by ordering the values from least to greatest. If there are two middle numbers, the average of the two would be the median.
Mode is the number that shows up most frequently in the data set.
Range is found by subtracting the lowest number from the highest number in the data set.
<u>Set 1</u>
Mean:
18+20+22+11+19+18+18=126
126÷7=18
Median:
11, 18, 18, 18, 19, 20, 22 → 18
Mode: 18
Range: 22-11=11
<u>Set 2</u>
Mean: 23+27+24+26+26+24+26+24=200
200÷8=25
Median:
23, 24, 24, 24, 26, 26, 26, 27 → 24+26=50 → 50÷2=25
Mode: 24 and 26
Range: 27-23=4
