Answer:
A)0.5
Step-by-step explanation:
We can see in the graph , that it is bell-shaped along x =2. A bell-shaped graph along one value is called symmetric graph and it represents a normal distribution.
Since, the give graph is symmetric around x=2, so the mean of the data is 2.
The point immediate left to the mean represents x-σ
so,
2 - σ = 1.5
So,
σ = 0.5
The sigma represents standard deviation.
Hence, Option A is correct ..
-7x < 102
First step is to divide both sides by -7. Because we are dividing by a negative number, we have to flip the signs.
-7x < 102
x > -102/7
The only one of your answer choices that is greater than -102/7 is A. 20.
Hope this helped!

Answer:
3.5cm
Step-by-step explanation:
Vol=πr²h
Transposing for h,=vol÷πr²
where r=22/2=11cm and taking π=3.142
h=1331/(3.142×(11)²)=3.5cm
