SOLUTION
From the given data the mean is 62 and standard deviation is 4
It is required to find the probability that a data value is between 57 and 62
That is:
The z scores is calculated using:
Using the x values it follows:
Also,
Thus the required probability is:
![P(-1.25The proability is:[tex]P(-1.25This can be expressed as percentage as:[tex]P(-1.25\lt z\lt0.75)=66.8\%](https://tex.z-dn.net/?f=P%28-1.25The%20proability%20is%3A%5Btex%5DP%28-1.25This%20can%20be%20expressed%20as%20percentage%20as%3A%5Btex%5DP%28-1.25%5Clt%20z%5Clt0.75%29%3D66.8%5C%25)
Therefore the correct option is C
In a right triangle with 45 degree angles the two sides are the same length. The hypotenuse is the length of the sides x sqrt(2)
The length of x = 3 and y = 3
Answer: 25
Step-by-step explanation:
Plug in x to the expression.
When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.
So this simplifies to, 
.
This then solves to 25.
Answer:
i dont want extra one i only want the though one
Well let's say you have a coordinate (2, -1)
Now if we reflect it upon the y-axis we'll end up at the coordinate (2,1)
We see that the x value is still the same.
