Answer:
0.913716
Step-by-step explanation:
Given a normal distribution :
Mean, x = 1050
Standard deviation, σ = 375
The Zscore = (x - mean) / σ
Zscore = (675 - 1050) / 275
Zscore = - 1.364
The probability :
P(Z > - 1.364)
P(Z > - 1.364) = 1 - P(Z < - 1.364) = 1 - 0.086284
P(Z > - 1.364) = 0.913716
Answer:
1. F=y/x
2. F(x)= fx
3. -6< x <-1
This is what I think, It look like it going to be the same answer for me but I don’t know if you want it
Step-by-step explanation: I try really I did
The perimeter of a semicircle consists of two parts. (the curve and bottom)
That curve is half the distance around the circle, since it's been split in half.
The distance around a circle, the circumfrence, is equal to 2πr, where r is the radius of that circle. In this case, the circumfrence of the entire circle would be 16π. and so that curve would have a length of just 8π.
Using 3.14 for π, 8π = 8×3.14 = 25.12.
As for the flat part, that is the diameter (distance across) our circle.
The radius is the distance from the center of a circle to its edge, and always has half the length of the diameter. (you can break the diameter down into two radii)
If our radius is 8 meters, our diameter (the flat part of that semicircle) must be 16.
Now we add up the two parts of the perimeter...25.12 + 16 = 41.12.
Answer:
For example 
Step-by-step explanation:
A non-unit fraction is a fraction of which the numerator is not equal to one. Additionally, the question does not state to pick three different ones and thus you can pick any fraction that when multiplied by three (since you take three fractions together) add up to a whole number (I'm picking the whole number to be one here just to make it simple), where the numerator is not equal to one of course.
For example: , because 3· = 
= 1
Infinitely many solutions can be found: for example 
Answer:
A) 12
Step-by-step explanation:
all triangle CBF is similar to triangle GEF by aa similarity.
EF/BF = EG/BC
6/18 = 4/BC
therefore BC must be 12.
