Answer: y = 0.5x + 35
Step-by-step explanation:
let x represent the number of minutes used by the customer in a month.
Let y represent the monthly cost for x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (435 - 215)/(800 - 360)
m = 220/440 = 0.5
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 360, y = 215 and m = 0.5 into y = mx + c. It becomes
215 = 0.5 × 360 + c
215 = 180 + c
c = 215 - 180
c = 35
The equation becomes
y = 0.5x + 35

Answer:
Julia is 48. Her youngest child is 12 and her oldest is 16.
Step-by-step explanation:
I guessed the youngest child's age (12) then I added 4 that equaled 16. Then I multiplied 12 by 4 which is 48. 48 plus 12 plus 16 equals 76. As for the 5d process I have no idea what that is your on your own for show work.
Answer:
Answer : A
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25 50 75
score : 64 74 80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is observation
term
If the number of observations is even, then the median is observation and observations.
given n=3, middle term is '74'
In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
= 80-64
= 16
IQR = 16
