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:
Mean=X=12
SD=3
W=7+2X
Mean(W)=7+2Mean(X)
Mean(W)=7+2(12)
=7+24=31
SD(W)=2SD(X)
SD(W)=2(3)=6

Evaluate the expression.
131 +-5
Answer:
126
Step-by-step explanation:
131 + - 5 can either be;
131 + 5 = 136
131 - 5 = 126
The question is probably asking what is 131 plus negative 5, hence the correct equation is; 131 - 5, and the correct answer is 126.

Write equation of a line in point slope form that passes through (3,8) and has a slope of
5?
Answer:
y = 5x - 7
Step-by-step explanation:
(3 , 8) ; slope(m) = 5
Equation of the line: y - y₁ = m( x- x₁)
y - 8 = 5(x - 3)
y -8 = 5x - 5*3
y-8 = 5x - 15
y = 5x - 15 +8
y = 5x - 7

In a standard Normal distribution, what percentage of observations lie above z = 0.16?
14.46%
43.64%
56.36%
85.54%
Answer:56.36
Step-by-step explanation:
The percentage of observations lying above z = 0.16 will be 56.36%. Then the correct option is C.
What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x - μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
The percentage of observations lie above z = 0.16 will be given as,
⇒ P(z < 0.16) x 100
⇒ 0.5636 x 100
⇒ 56.36%
The percentage of observations lying above z = 0.16 will be 56.36%. Then the correct option is C.

Which equation is equivalent to the given equation?
-4(x-5)+8x=9x-3
Answer:
b, its the logical answer
Step-by-step explanation:
The value of the expression -4(x-5)+8x=9x-3 will be -5x = -23 The correct option is D.
What is an expression?
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is -4(x-5)+8x=9x-3. The solution to the expression is given below:-
-4(x-5)+8x=9x-3
-4x + 20 + 8x= 9x - 3
4x - 9x = -20 - 3
-5x = -23
Therefore, the value of the expression -4(x-5)+8x=9x-3 will be -5x = -23 The correct option is D.

ordered pair will be (x, (k(x))
for example (-4, -3)
do this for all other points
slope can be found by taking the change in y over change in x
so -2- -4 divided by -2 - - 3 = 2/1 = 2
