Step-by-step explanation:

a. Range of group 1 = 65 - 31 = 34 and range of group 2 = 64 - 32 = 32

b. Group 1 had 5 numbers in the 40s and group 2 had 4 so since 5 > 4 the answer is Group 1.

c. The median of Group 1 will be the 9th term which is 46 and the median of Group 2 will be the average of the 8th and 9th terms which is (50 + 52) / 2 = 51 so since 51 > 46 the answer is Group 2.

Step-by-step explanation:

(a)

range = largest no. - smallest no.

group 1: 65 - 31 = 34

group 2: 64 - 32 = 32

(b)

group 1: 42, 42, 46, 46, 46

group 2: 43, 44, 44, 46

group 1 has more typing speeds.

(c)

median is the middle number.

group 1: 31, 33, 35, 37, 42, 42, 46, 46, 46, 50, 53, 54, 56, 56, 57, 57, 65

group 2: 32, 35, 38, 43, 44, 44, 46, 50, 52, 53, 53,  55, 56, 56, 60, 64

(50+52)/2 = 51

46 < 51 group 2 has a larger median value.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
