The mean is 10,
The median is 10,
And there is no mode.
The mean of a set of numbers is the sum divided by the number of terms,
7+15+12+6+10=50
There are 5 numbers in the set,
50/5=10.
10 is the mean.
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers,
6, 7, 10, 12, 15,
10 is in the middle so it is the median.
The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.
Just so you don’t confuse the data with the group sets,
The actual data set is 7, 15, 12, 6, and 10
This data paired with score column or group set means that,
10 people got a score of 1-10
6 people got a score of 11-20
12 people got a score of 21-30
15 people got a score of 31-40
And 7 people got a score of 41-50 :)
Answer:
Option B. After 20 minutes, Shari had 6 kilometers left to run
Step-by-step explanation:
Let
x ----> the time in minutes
y ----> the distance remaining in kilometers
we have the ordered pair (20,6)
That means
x=20 min
y=6 km
so
After 20 minutes, Shari had 6 kilometers left to run
X + 0.5 + 3x - 2 = 3x + 1.5
X= 3.5
Putting the all x on the right side and distributing all the numbers on the left side
$20-$14.56=$5.44
The mechanic would get $5.44 back as change.
There is not enough information to answer the question. To answer it, you need to know how much gas is in her gas tank and how far she needs to travel.
