Determine the mean
The mean (M) of a data is calculated as thus:

Where
n = number of data.
In this case,
n = 5
and
= sum of data
So, the formula becomes



<em>Hence, the mean is 77</em>
The answer is 11. 5(2) + 1= 10 + 1 = 11.
Answer:
-3
Step-by-step explanation:
(x+7)4 =16
16/4=4
X+7 = 4
4 - 7 = -3
Answer:
Step-by-step explanation:
Substitute 15 in place of all your x and set up the following:
(4*15+4)^2 + (3*15)^2 = c^2
64^2 + 45^2 = c^2
4096 + 2025 = c^2
