Answer:
4 oil changes
Step-by-step explanation:
Given that:
Distance after first oil change = 5000 miles
Subsequent oil changes = 3300 miles
If distance in miles moved per week = 250 m
Number of weeks per year = 52
Total miles moved per year = (250 * 52) = 13000 miles
Let Number of oil change per year = n
Difference between successive oil change = d = 3300 miles
Using the relation :
Total miles = Ist change + (n - 1)d
13000 = 5000 + (n - 1)3300
13000 = 5000 + 3300n - 3300
13000 = 1700 + 3300n
13000 - 1700 = 3300n
11300 = 3300n
n = 3.424
Hence, number of oil. Changes in first year = 4
I think it’s x = 9 hope it helps :D

Answer: B. 2</h3>
How I got that answer:
The data set for Marcus is
2, 3, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 10, 10
The five number summary is
- min = 2
- Q1 = 6
- median = 7
- Q3 = 8
- max = 10
So the interquartile range (IQR) is
IQR = Q3 - Q1
IQR = 8 - 6
IQR = 2
F(x) = 0.85x because the final price is 85% of the original price since 15 percent is taken off.
Answer:
if this isn't approximate
then 218 miles
And if you want me to combine $20.95 with 82 cents then the answer would be 8.2 miles
Step-by-step explanation:
82 cents x 218 = $178.76
$21.77 X 8.2 = $178.51
