Answer:
8
Step-by-step explanation:
Recall the formula for the population mean of a data set:
We already know that μ is 6 and the sum is 48. Substitute:
Divide both sides by 48:
Reciprocal of both sides:
Thus, there are 8 scores in the population size.
And we're done!
The mean can be revealed by looking at the ranges of numbers. You need exact numbers to find a mean.
Median is just to middle. Hopefully you can find the middle bar.
Step-by-step explanation:
((7²-2×7×3+3²)/8)-1=( 16/8)-1=2-1=1
Answer:
6 = 8 + 9n
Step-by-step explanation:
Based on the problem, you can also do this:
8 + 9n = 6

Step-by-step Answer:
The coordinates of the mid-point of a segment whose end-points are known is the average of the coordinates of the end-points.
Here, the end-points are: (-11,0), (9,-1)
So the x-coordinate of the mid-point is (-11+9)/2 = (-2/2) = -1, and
the y-coordinate of the mid-point is (0-1)/2 = -0.5
So the mid-point is (-1,-0.5)
Check the numbers by plotting the point on the graph!
