Answer:
In a discrete probability distribution of a random variable X, the mean is equal to the sum over every possible value weighted by the probability of that value; that is, it is computed by taking the product of each possible value x of X and its probability p(x), and then adding all these products together, giving. .

The number of yodelers is twice the number of xylophones, how do I write this in a equation ?
Answer:
X=(Y*2) // Y=(X/2)
Step-by-step explanation:
Xylophones = "X"
Yodelers = "Y"
First Equation: X=(Y*2) essentially just explains that the xylophones is equal to the yodelers times 2
Second Equation: Basically the same thing, but rather than multiplying the yodelers by two, it divides the xylophones in half.

What is the equation in slope-intercept form of the line that passes through (2, 3) and is parallel to the line through (-2, 1) and (7, 1)?
9514 1404 393
Answer:
y = 3
Step-by-step explanation:
The slope formula can be used to find the slope of the parallel line.
m = (y2 -y1)/(x2 -x1)
m = (1 -1)/(7-(-2)) = 0
The line is a horizontal line, so the y-intercept must be chosen to match the y-value of the given point.
y = 3
_____
If you want to see the slope of zero in the slope-intercept form equation, you can write the equation as ...
y = 0x +3
It is pretty unusual to keep 0 terms in an equation. Usually, they are eliminated when the equation is simplified.

How do I find the length of SU?
Answer:
itll be WU multiplied by 2.
Step-by-step explanation:
this is because TV is the bisector, so WU and SW are the same length. just multiply it by 2.

HELP PLEASEEEEEEEEEEEEE!
Answer:
3.) x=3
4.) x=11
Step-by-step explanation:
3.) 80= 27x-1
x=3
4.) 5x+5+9x+21= 180
14x+26= 180
x=11
Answer: #3) x= 3. #4) x= 11
Step-by-step explanation:
For #3 these angles are alternate exterior angles. (Opposite sides of the transversal and outside of the parallel lines) Alternate exterior angles are equal, so set these two equal to each other to solve for x. 27x-1 = 80 Add 1 to both sides. 27x = 81. Divide both sides by 27. X = 3. For #4, these angles are same side interior angles. (Same side of the transversal and inside the parallel lines) Same side interior angles sum to 180 degrees. (5x+5) + (9x+21) = 180. Combine like terms. 14x + 26= 180. Subtract 26 from both sides. 14x = 154. Divide both sides by 14. X = 11

What is the equation of a circle centered at the origin with radius 20
Answer:
we have a rule
(x-h)²+(y-v)²=r²
while h is the x intercept
v is y intercept
r is the radius
so the answer will be
x²+y²=400
or
x²+y²=20²

Angles 1 and 2 are supplementary.
• The measure of angle 1 is (2x - 3) ◦
• The measure of angle 2 is (-5x + 423) ◦
What is the measure of angle 2?
Answer:
1 = 157°
2 = 23°
Step-by-step explanation:
because the angles are supplementary, their angles will add up to 180°set up the equation (2x-3)+(-5x+423)=180combine like terms to get -3x+420=180subtract 420 from 180 to get -3x=-240divide by three and get x=80now plug in 80 for x in both equations
