Answer:
- Minimum 2 hours
Step-by-step explanation:
Sunset Canyon Bikes charges $1.50 per hour and a $8.00 rental fee.
<u>Equation:</u>
- y = 1.5x + 8
Blue Canyon Bikes charges $3.50 per hour and a $4.00 rental fee
<u>Equation:</u>
- y = 3.5x + 4
The second equation has a greater slope so beyond the intersection of the lines the Sunset Canyon Bikes will have lower price.
<u>The point of intersection is:</u>
- 1.5x + 8 = 3.5x + 4
- 3.5x - 1.5x = 8 - 4
- 2x = 4
- x = 2 hours
The graph is attached, where the red line is the first equation and the blue line is the second one.

Answer:
22.8 and 37.5
Step-by-step explanation:
Given the
The weights (in pounds) of 18 preschool children are
32, 20, 25, 27, 31, 22, 30, 23, 44, 37, 33, 45, 41, 24, 34, 21, 39, 29
To find its 20th percentile and 75th percentile.
In ascending order we get like this
Position X (Asc. Order)
1 20
2 21
3 22
4 23
5 24
6 25
7 27
8 29
9 30
10 31
11 32
12 33
13 34
14 37
15 39
16 41
17 44
18 45
Percentile position = (no of entries +1)20/100 = 19/5 = 3.8
Since posiiton is not integer we use interpolation method.
The value of 3.8 - 3 = 0.8 corresponds to the proportion of the distance between 22 and 23 where the percentile we are looking for is located at.
Hence 20th percentile =
So answer is 22.8
----------------------
75th percentile
Percentile posiiton = 19(75)/100 = 14.25
75th percentile=
