The mean of a dataset is the sum of all data elements divided by the count of the elements.
The location of the 6th score relative to the mean is 5 points below the mean
Let:
<em> Mean</em>
<em> 5 scores</em>
<em> 6th scores</em>
Given that:
The 5 scores that are 1 above the mean implies that:
The mean of a dataset is calculated using:
So, we have:
Open brackets
Multiply both sides by 6
Make b the subject
This means that the 6th score is 5 points below the mean

15 quarters= $3.75
21 nickels =$1.05
______________
36 coins = $4.80
Answer:
12
Step-by-step explanation:
First, find the total number of vehicles sold.
15 SUVs were sold, and 80 others were sold
15+80
95
So, 95 vehicles were sold in total.
Now we can make a proportion
15 out of 95 vehicles were SUVs, and we can expect x out of 76 vehicles to be SUVs
15/95=x/76
Cross multiply
95*x=15*76
95x=1140
To solve for x, we need to get x by itself. Since x is being multiplied by 95, divide both sides by 95. This will cancel out the 95, and leave x isolated.
95x/95=1140/95
x=12
So, 12 out 76 vehicles should be SUVs

The formula to find the circumference of a circle is C=2*pi*r.
Substitute 9 1/4 or 9.25 for r.
C=2*pi*r
C=2*pi*9.25
C=18.5pi
The circumference of the circle would be 18.5pi.
