A fair number cube with sides labeled from 1 to 6 is rolled 20 times. the results of the simulation are shown in a dot plot. which dot plot models an unfair data-generating process?
Answers
The dot plot will be 1:4, 2:4, 3:0, 4:4, 5:4,6:4 and there is a face with 3 has not rolled option second is correct.
What is dot plot?
A dot plot, also referred to as a dot chart or stripe graph, is a sort of simple histogram-like figure used in statistics for little data sets with values falling into a number of discrete bins.
Since the width of each "bar" of dots is equal to the number of items in a certain class, a dot plot is similarly to a bar diagram.
We have:
A fair number cube with sides labeled from 1 to 6 is rolled 20 times.
Total number on, a fair number of cubes = 6
So the dot plot can be shown as:
1:4, 2:4, 3:0, 4:4, 5:4,6:4
There is a face with 3 has not rolled.
Thus, the dot plot will be 1:4, 2:4, 3:0, 4:4, 5:4,6:4 and there is a face with 3 has not rolled option second is correct.

Answer:
Option A is correct
2 hours, 142 miles
Step-by-step explanation:
As per the statement:
The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below:
Car A
y = 55x + 32 ....[1]
Car B
y = 42x + 58 ....[2]
We have to find after how many hours will the two cars be at the same distance from their starting point.
Since, two cars be at the same distance
equate [1] and [2] ;
⇒
Subtract 42x from both sides we have;
⇒
Subtract 32 from both sides we have;
Divide both sides by 13 we have;
x = 2 hours
Substitute in [1] we have;
miles
Therefore, after 2 hours will the two cars be at the same distance from their starting point and 142 miles will that distance be
42x+58=55x+32
13x=26

12.62 x 40 = 504.8
time and a half is the amount you get paid + half the amount you get paid
so half of 12.62 is 6.31 + 12.62 = 18.93
18.93 x 7 = 132.51
504.8 + 132.51 = 637.31
