Step-by-step explanation:
4H + 7W 《56
H = 7, W = 4
4(7) + 7(4) = 56《56
H = 5 , W = 5
4(5) + 7(5) = 55《56
Answer:
2255.31 cu.m
Step-by-step explanation:
Volume of a cylinder = πr²h
Given radius r = 6.5m
Height h = 17m
Volume = π × 6.5²×17
Volume = 3.14×6.5²×17
Volume of the cylinder = 2255.31cu.m
The mean of this test will be 57.
<h3>What is Standard Deviation and Mean?</h3>
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.
The mean can be used to get an overall idea, or picture, of the data set.
Let Mean be 'm'
and standard deviation= 
So, m-2
=49
and, m +
=61
Solving the above two equation we get

Now, m= 61-
= 61-4
= 57
So , the mean of this test will be =57
