Answer:
62.83
because you take 20, divide it by 2 to get the radius then you have the equation 2π(10)
Answer:
The shorter side: longer side is 385:512
Step-by-step explanation:
We are given that A man has 166 feet of fencing to build the pen
We are supposed to find If one end is a square, find the outside dimensions, if a = 6.
Side of square = x
Perimeter of square =
a=6
Length of rectangular part = x+a = x+6
Breadth of rectangular part = x
Perimeter of rectangular part = 2(l+b)=2(x+6+x)=2(2x+6)
So, ATQ
4x+2(2x+6)=166
4x+4x+12=166
8x=154
x=19.25
Shorter side = 19.25
Longer side = x+6=19.25+6=25.6
So, the shorter side: longer side =
Hence the shorter side: longer side is 385:512
The proportion of people with IQs above 130 is 2.3%.
<h3>How to calculate the value?</h3>
Normal distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Here the mean is 100 and a standard deviation of 15.
µ = 100, σ = 15
P(X > 130) =
= P( (X-µ)/σ > (130-100)/15)
= P(z > 2)
= 1 - P(z < 2)
Using excel function:
= 1 - NORM.S.DIST(2, 1)
= 0.023 = 2.3%
The value is 2.3%.
