Answer:
1) -2.13
2) 2.57
3) 33
Step-by-step explanation:
1)
3(8 + 5h) = -28 Distribute the 3
24 + 15h = -28 Subtract 24 from both sides of the equation
15h = -32 Divide both sides by 15 and round
h = - 2.13
2)
19 = 7(3n - 5) Distribute the 7
19 = 21n - 35 Add 35 to both sides of the equation
54 = 21n Divide both sides of the equation by 21
2.57 = n
3)
6s - 7s = -33 Combine the s's
-s = -33 Multiply both sides by -1
s = 33

Step-by-step explanation:
Answer: The cumulative frequency of club members who exercise publicly for six or fewer times per week = 38
Step-by-step explanation:
The given results of the survey:
0 visits per week: 13
1-3 visits per week: 17
4-6 visits per week: 8
7 or more visits per week: 17
The cumulative frequency of club members who exercise publicly for six or fewer times per week = Frequency for 0 visits + Frequency for 1-3 visits per week + Frequency for 4-6 visits per week
= 13+17+8
=38
Hence, the cumulative frequency of club members who exercise publicly for six or fewer times per week = 38
