As the mean is 90 then, the sum of the quantities are..
90×4 = 360
the scores you have are 86, 85, 96
so the answer is.
85+86+96= 262
360-262= 98
the fourth score is 98.

Answer with Step-by-step explanation:
We are given that a function
Assign each whole number to its largest place value digit.
We have to find the value of x that makes the equation 7 a true statement.
When f(x)=7
Then, the possible values of x are 7,127,27,257,... .
Because f(7)=7
f(127)=7
f(27)=7
f(257)=7
Therefore, the value of x =7,127,257,27,..
X + 11 + 8x = 29. We need to solve for x.
First, on the left side, you have "x" and "8x": You can always add 2 numbers with the same variable, so you have 1 number: x + 8x = 1x + 8x = (1+8)x = 9x
So we get:
9x + 11 = 29
Now subtract 11 from both sides (You can't do any operation if you don't do it both sides), so you can get the variable alone on the left side, and the numbers on the right side:
9x + 11 = 29
9x + 11 - 11 = 29 - 11
9x = 18
Now divide both sides by 9, so you can transform the coefficient of x to one, and have the numeric value of x on the right side:
9x = 18
(9x)/9 = 18/9
x = 2
So x+11+8x = 29 for x = 2.
You can recheck your answer (very important):
x + 11 + 8x = 2 + 11 + 8*2 = 2 + 11 + 16 = 13 + 16 = 29
The answer has been approved.
Hope this Helps! :)
Look to the table to find the answer.
The average rate of change is the slope of function taken on the interval [1,3].
The image of the function posted does NOT have a slope of 3 on [1,3] . Looking at the able you see (1,-2) and (3,6) So it has a slope of 4 = (6- -2)/(3-1) on that interval..
Go on to the next function and check the slope for the x interval [1,3] until you find one that is = 3
