He box plots below show the distribution of grades in one class on two tests. A box plot titled Test 1 Grades. The number line goes from 72 to 100. The whiskers range from 72 to 98, and the box ranges from 78 to 92. A line divides the box at 84. Test 1 Grades A box plot titled Test 2 Grades. The number line goes from 72 to 100. The whiskers range from 74 to 94, and the box ranges from 79 to 89. A line divides the box at 84. Test 2 Grades Which measures of center and variability would be best to use when making comparisons of the two data sets?

c

step-by-step explanation:

because of the levels

they will manufacture 8496 cars

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

include a picture of the drawing in order for me to
