Answer:
There are approximately 171 families in the sample.
Step-by-step explanation:
Percentile meaning:
When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.
Twenty-four of the families in the sample turned on the television for 23 hours or less for the week. The 14th percentile of the data is 23 hours.
This means that 24 is 14% of the total number of families.
Approximately how many families are in the sample?
Using a rule of three.
24 - 0.14
x - 1
0.14x = 24
x = 24/0.14
x = 171.4
Rounding to the nearest integer
There are approximately 171 families in the sample.

Answer:
see attached
Step-by-step explanation:
If you plot the points on the graph, you notice that the run (change in x) is 3 for each "rise" (change in y) of -1, so the slope is ...
m = rise/run = -1/3
The middle point is on the y-axis, so is the y-intercept.
In slope-intercept form, the equation is ...
y = mx + b . . . . . . where m is the slope (-1/3) and b is the y-intercept (4)
y = -1/3x +4 . . . . equation
