Write the in slope intercept form. It has coefficient m=-4/7 and passes through the point (14,3)
1 answer:
Answer:
y = -4/7x + 11
Step-by-step explanation:
Given the slope, m = -4/7, and the set of ordered pairs, (14, 3):
We can substitute these values into the slope-intercept form, y = mx + b, and solve for the y-intercept:
Let x = 14
y = 3
m = -4/7
y = mx + b
3 = -8 + b
Add 8 on both sides of the equation to solve for y-intercept, b:
3 + 8 = -8 + b + 8
11 = b
Therefore, given our slope, m = -4/7, and our y-intercept, b = 11:
Our linear equation in slope-intercept form is:
y = -4/7x + 11.

Answer:
1). Mean = 2.275
2). Median = 2 vehicles
Step-by-step explanation:
From the given table,
Number of vehicles (x) Frequency (f) (f)×(x) Cumulative freq.
0 11 0 11
1 52 52 63
2 66 132 129
3 35 105 164
4 19 76 183
5 12 60 195
6 5 30 200
Number of households = 200
Mean =
=
= 2.275
Median = value of observation
= value of observation
= Value of 100.5th observation
= Since 100.5th observation lies in the row of cumulative freq. = 129
= 2
Therefore, median number of registered vehicles per California household
= 2 vehicles
