The random variable X has mean 12 and standard deviation 3. The random variable W is defined as W = 7+2X. What are the mean and standard deviation of W?
A. The mean is 24, and the standard deviation is 6.
B. The mean is 24, and the standard deviation is 13.
C. The mean is 31, and the standard deviation is 3.
D. The mean is 31, and the standard deviation is 6.
E. The mean is 31, and the standard deviation is 13.
Answer: D. The mean is 31, and the standard deviation is 6.
Step-by-step explanation:
Given the data :
X = mean = 12 ; Standard deviation = 3
W = 7 + 2x
Variance of W = 2x
Variance = Standard deviation²
(2x)² = 4x²
Variance
Standard deviation of X = 3
Variance (W) = 4*3² = 4 * 9 = 36
Variance (W) = 36
Standard deviation = sqrt(variance)
Standard deviation = sqrt(36) = 6
Mean ; of x = 12
Mean(W) = 7 + 2(12)
Mean = 7 + 24
Mean = 31

Step 2: Simplify
Distribute -2.5: 7.5 - 10n - 20Combine like terms: -10n - 12.5For simplifying an expression, there are some rules about the order in which the calculations should be performed. The order of rules is called BODMAS. Each letter in this word stands for an operation.
B = BracketsO = OffD = DivisionM = massA = additionS = substraction→ -2.5(-3 + 4n + 8) = 0
→ 7.5 + (-10n) + (-20) = 0
→ 7.5 - 10n - 20 = 0
→ -10n - 20 + 7.5 = 0
→ -10n - 12.5 = 0
→ -10n = 12.5
→ n = 12.5 ÷ -10
→ n = -1.25
2(5x+7)=16
what the answer?
Answer:
x = 1/5
Step-by-step explanation:
2(5x + 7) = 16
2 * 5x + 2 * 7 = 16
10x + 14 = 16
10x = 16 - 14
10x = 2
x = 2/10
x = 1/5

Solve the following formula for the indicated variable.
– 5x – 3y = 13: solve for y.
9514 1404 393
Answer:
y = -5/3x -13/3
Step-by-step explanation:
In any "solve for ..." problem, it is useful to start by identifying where the target is and what has been done to it. Here, y is in one term on the left side of the equation and it has had these things done to it:
multiply by -3add -5xWe want to undo these in reverse order. We undo addition by adding the opposite. We undo multiplication by multiplying by the reciprocal (equivalently, dividing). Whatever we do to one side of the equation, we must also do to the other side.
So, first we add the opposite of -5x to both sides of the equation.
-5x +5x -3y = 13 +5x
-3y = 13 +5x . . . . . . . . . collect terms
Next, we undo the multiplication by -3. We can do that by multiplying both sides by 1/(-3) = -1/3.
(-1/3)(-3y) = (-1/3)(13 +5x)
y = -5/3x -13/3 . . . . . also we rearranged the terms to standard form
The triangles are similar.

Find the least common multiple (LCM) of 4 and 5.
9514 1404 393
Answer:
20
Step-by-step explanation:
4 and 5 have no common factors*, so their least common multiple is their product:
4 × 5 = 20
The LCM of 4 and 5 is 20.
_____
* We're concerned with integer factors greater than 1. Of course, 1 is a factor of everything, We could say this as "no common prime factors". For computing the LCM, we really want the GCF (greatest common factor) for use in the formula ...
LCM(m, n) = mn/GCF(m, n)
