8 and 9 because 8 x 8= 64 and 9 x 9 = 81. Between 64 and 81 is 75.
Answer: choice B
Step-by-step explanation:
the mean is the sum of terms divided by the number of terms
mean=75.77, has to be rounded so it is 75.8
mode = 63 the one who appears the most
median is 76.5
hi
x/6 = 10
In a equation , you can use every math operation you know as long as you do the same thing on both sides.
Here we have x/6 = 10
But what I want is x .
Here X is split in 6. So I 'm going to multiplicate all by 6 to find the original amount of X
In bold operation that are often not written but that you must understand to do that kind of exercices.
So : x/6 = 10
(x/6) *6 = 10 *6
6x/6 = 60
x = 60
-2/3 <em>b</em> + 4 = 0
Add -4 to both sides to eliminate the 4 on the left:
-2/3 <em>b</em> + 4 - 4 = - 4
-2/3 <em>b</em> = -4
Multiply both sides by -3/2 to eliminate the -2/3 on the left:
-3/2 • (-2/3 <em>b</em>) = -3/2 • 4
<em>b</em> = -12/2
Simplify the solution:
<em>b</em> = -6
