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
Midpoint
-1 = (xG - 2)/2
-2 = xG - 2
xG = 0
3 = (yG + 5)/2
6 = yG + 5
yG = 1
Answer
The coordinates of endpoint G(0, 1)
Answer:
4 is not the constant. 2 is.
Step-by-step explanation:
In the following equation: y = 4x + 2
x and y are variables. x can be any given number, and y would be the resulting answer.
4 is not the constant, because the product it will produce varies on what x will be.
2 is a constant, because it will not change regardless what is put into x. It will continue to stay as 2.

Answer:
1 mile = 8.5 minutes
Step-by-step explanation:
<u>Determining the equation:</u>
Kira ran 8 1/5 miles in 69 7/10 minutes.
⇒ Kira = 8 1/5 miles = 69 7/10 minutes
⇒ 41/5 miles = 697/10 minutes
<u>Simplifying both sides:</u>
⇒ 41/5 miles = 697/10 minutes
⇒ 41 miles = 697/2 minutes
<u>Using cross multiplication:</u>
⇒ 41 × 2 miles = 697 minutes
⇒ 82 miles = 697 minutes
<u>Dividing 82 both sides:</u>
⇒ 82 miles = 697 minutes
⇒ 82/82 miles = 697/82 minutes
⇒ 1 mile = 8.5 minutes
