Since about 95% of a normal distribution falls within two standard deviations of the mean
, it follows that 5% lie outside this range, with 2.5% lying to either side of it.This means
, with the remaining 2.5% lying above
.
This means for a score to belong in the top 2.5%, it's corresponding z-score must be higher than 2.
Fred scores 13.1 on the test. The corresponding z-score is
which is barely higher than 2, but high enough to earn that certificate.
The answer would be B. You know B and Y are equal and AB and XY are equal, so you just need the last side included in the angle.

Answer:
B
Step-by-step explanation:
V=1/3Bh
v=1/3s^2 (1/2s)
v=1/6s^2
Answer:
6x + 1
3x + 3
6x + 9
Step-by-step explanation:
1)
To find the missing number, compare both sides of the equation. If the variable terms are the same and the constant terms are different, then the equation has no solutions.
2x + 9 + 3x + x = _x +_
6x + 9 = _x + _
6x + 9 = 6x + 1
2)
To find the missing number, compare both sides of the equation. If the variable terms are the different and the constant terms are either different or same, then the equation has one solution.
2x + 9 + 3x + x = _x + _
6x + 9 = _x + _
6x + 9 = 3x + 3
3)
When equation is true for every possible value of x.
To find the missing number, compare both sides of the equation. If the variable terms are the same and the constant terms are same, then the equation has no solutions.
2x + 9 + 3x + x = _x + _
6x + 9 = _x + _
6x + 9 = 6x + 9
6x = 6x +9 -9
6x = 6x
6x/6 = x
x = x
