3.75.....rounded to the nearest dollar would be 4.00
Hi there!
Let's solve this problem step by step!
The cost of 1 round of golf is $18
and therefore the total cost for all of the tickets is $18 ×
the amount of golf plays, mathematically $18 × g, hence 18g
The membership cost of 1 month is $250
and therefore the total cost for all of the tickets is $250 ×
the amount of months, mathematically $250 × m, hence 250m.
Now we can set up the equation. The only thing we need to do is adding up the individual functions.
Answer:
C = 250m + 18g
A) The total number is the sum of all the frequencies
2+5+8+12+11+6=44
Answer: 44
B) The width is (upper limit - lower limit) / 2
(35-21) / 2 = 7
(50-36) / 2 = 7
(65-51) / 2 = 7
(80-66) / 2 = 7
(95-81) / 2 = 7
(110-96) / 2 = 7
Answer: the width is 7
C) The midpoint is the lower limit + the width
36+7=43
Answer: the midpoint is 43
D)The modal is the class with more frequency
In this case 66-80 with 12
Answer: class 66-80
E) We use the width formula
lower limit = 111
width = 7
upper = (width * 2) - lower
upper = (7 * 2) + 111
upper = 125
Answer: class 111-125
