If you have an average of 97.2 on your current exam and you get a 99 on your next exam, your average will increase.
- Mean in mathematics is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the total number of values.
- To find the average, sum all the values in the set. Then divide the total by the number of values.
We have the current examination mean, xold = 97.2
Now, we receive, x = 99 on the next examination, the new mean will be:
xnew = (xold + x)/N
xnew = (97.2+99)/2
xnew = 196.2/2
xnew = 98.1
The new average is 98.1
98.1 > 97.2
So if you score 99 on your next exam, your average will increase.

Let f(y)=x.
Answer:
f(n) = n/36
Step-by-step explanation:
The length of a string is given in yards, is a function f(n) of the length n in inches.
We have to write a function rule for this situation.
∵ 36 inches = 1 yard
∴ 1 inch = 1/36 (yard)
∴ n inches = n/36
and function representing the length will be
f(n) = n/36
Answer:
y = -3x - 5
Step-by-step explanation:
