The mean of a sequence of numbers is the average.
The true statement is: 
The given parameters are:
The mean of a dataset is calculated as:
So, we have:
Multiply both sides by m
When the sequence is split into two, we have:
Where:
So, we have:
Hence, the true statement is:

5x+3(x-2)=90
5x+3x-6=90
8x-6=90
+6 +6
8x=96
\8 \8
X=12
What's up? we can see the angles on the bottom look the same, so we just need to subtract 180-32= 148 and 148/2= 74
x= 74°
best of luck with your studies
Answer:
2 standard deviations of the mean. so, 41 to 65
Step-by-step explanation:
from the empirical rule we know that for 95% we are in 2 standard deviations of the mean. so:
53- 6- 6 = 41
*2 minus 6s because 2 standard dev. with the mean
53 + 6 + 6 = 65
