Answer:
Mean = 30
standard Deviation = 2.74
Step-by-step explanation:
Formula
mean = np
Standard Deviation = 
from the question = 40
P = 75% or 0.75
q = 1 - p = 1 - 75% or 1 - 0.75
To find mean
mean = 40 x 0.75
= 30
For Standard Deviation (SD)
Standard Deviation =
= 
= 
:. Standard Deviation = 2.74
Answer:
Can't really expand x and 0, so I guess it would just be x * 0
Step-by-step explanation:
explained above :)
He will need 17 inches of ribbon.
The diagonal splits the square into two right triangles. We can then use the Pythagorean theorem to find the length of the diagonal (the hypotenuse of the triangle):
12² + 12² = x²
144 + 144 = x²
288 = x²
Take the square root of both sides:
√288 = √x²
16.97 = x
17≈x
To solve an equation that contains LIKE TERMS you just have to combine them together.
For example, 3x-22+2x=48.
3x-22+2x=48 Add both x's together.
5x-22=48 <this will be the answer. After that, just solve it like a regular equation.
If the equation that you're trying to solve looks like this, 5x-41=59+9x
Subtract the smallest number on both sides.
5x-41=59+9x
-5x -5x
-41=59+4x <this will be your answer and then you just have to solve it like a regular equation
