Answer:
68.269%
Step-by-step explanation:
We start by calculating the z-scores of both numbers
Mathematically;
z-score = (x-mean)/SD
where x represents the raw score
For 82;
z-score = (82-87)/5 = -5/5 = -1
For 92;
z-score = (92-87)/5 = 5/5 = 1
So the probability we want to calculate would be;
P(-1 < x< 1)
We can use the standard normal distribution table to get this.
By using the distribution, P(-1<x<1) = 0.68269
By converting this to percentage, we have 68.269%
Answer:
1?
Step-by-step explanation:
Answer:
Step-by-step explanation:
X - 2
x^2-x+1 | x^3 - 3x^2 + 3x - 2. x^3 - x^2 + x
-2x^2 + 2x -2 -2x^2 + 2x - 2 0
Quotient = x - 2
Answer:
Solving for X in a Right Triangle
Step-by-step explanation:
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
