Answer:

b.) arithmetic mean- 13.85
c.) varience- 0.69
Answer:
d=4
Step-by-step explanation:
Agency 1:
Total cost of renting a car=24.50d + 15.99
Agency 2:
Total cost of renting a car=27.50d + 3.99
Where, d=No. of days of renting the car
Which equation could be used to find the number of days, d, at which the rental fee is the same for both agencies?
The equation is by equating agency 1 and agency 2 equation
24.50d + 15.99 = 27.50d + 3.99
Collect like terms
24.50d - 27.50d = 3.99 - 15.99
-3d = -12
Divide both sides by -3
d= -12 / -3
=4
d=4
Check
Agency 1:
24.50d + 15.99
= 24.50(4) + 15.99
= 98 + 15.99
= 113.99
Agency 2:
27.50d + 3.99
= 27.50(4) + 3.99
= 110 + 3.99
= 133.99
First partDetermine 2 points that pass through x + 2y = 5
(i) If x = 1
x + 2y = 5
1 + 2y = 5
2y = 4
y = 2
(ii) If x = 3
x + 2y = 5
3 + 2y = 5
2y = 2
y = 1
Two points that pass through this line are (1,2) and (3,1)
Second partDetermine 2 points that pass through 3x = 15 - 6y
(i) If x = 1
3x = 15 - 6y
3(1) = 15 - 6y
3 = 15 - 6y
6y = 15 - 3
6y = 12
y = 2
(ii) If x = 3
3x = 15 - 6y
3(3) = 15 - 6y
9 = 15 - 6y
6y = 15 - 9
6y = 6
y = 1
Two points that pass through this line are (1,2) and (3,1)
BOTH OF THE LINE pass through the same two points, that means the lines are the same because they overlap. Look at the attachment.
