Answer:
C
Step-by-step explanation:
a is defined first as 5. So a = 5.
b is defined after the circle b = -2
a^2 = 5^2 = 25
B^4 =(- 2)^4 = 16
Therefore sqrt(a^2 * b^4) = sqrt(25 * 16) = sqrt(400) = 20
The answer is C
Cross multiply or just multiply both sides by 24
24x/6=36
4x=36
divide both sides by 4
x=9

Answer:
89
Step-by-step explanation:
Hi, there to find the mean
you need add the numbers and count how many numbers are there and divide
In this case 98+78+84+96= 356
Now we will count
there are 4 numbers
= 89
Your mean will be 89
If you ever have trouble with mean remember this
Mean
well it is supposed to be:
Sum of Data Points/Number of Data Points
