Answer:
Variance σ² having standard deviation 2.5 is 6.25.
Step-by-step explanation:
The standard deviation is basically the square root of the variance.
So, if want to find the variance of the data we simply take square of standard deviation to get the variance of data.
standard deviation = σ = 2.5
taking square on both sides
(σ)² = (2.5)²
σ² = 6.25
So, variance σ² having standard deviation 2.5 is 6.25.
4+7=11
11/2=5.5
round to the nearst whole number
Answer:
(x + 3)(x + 4) = 110
or x² + 7x + 12 = 110
Step-by-step explanation:
2x +8=2x+8
2x-2x=8-8
0x=0
So the answer is 0
So, we can do either
28500- 16% five times
or
28500-(16%*5)
either would give you 5700
i think this is the correct answer
