According to the discrete distribution given, the standard deviation is of: 0.98.
The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability, hence:
[tex]E(X) = 0.1296(0) + 0.3456(1) + 0.3456(2) + 0.1536(3) + 0.0256(4) = 1.6[/tex]
The standard deviation is the square root of the sum of the multiplication of each probability and the difference squared between the observation and the mean, hence:
[tex]\sqrt{V(X)} = \sqrt{0.1296(0-1.6)^2 + \cdots + 0.1536(3-1.6)^2 + 0.0256(4-1.6)^2} = 0.98[/tex]
The standard deviation is of 0.98.

Match the graph with the correct equation.
A. y + 2 = –(x – 4)
B. y + 2 = –(x +4)
C. y – 2 = –(x – 4)
D. y + 2 = (x –2)
Answer:
A. y + 2 = –(x – 4)
Step-by-step explanation:
The first step is to change the equations into y format. y= mx + b.
The y- intercept of this graph is at the point (0,2). Since the line is going down, the slope is negative. Therefore it would be: y+2 = -(x-4)
If changed it would be y= -x + 2.
Hope it help
...............................................................................................................................................
From the graph it is clear that the line is passing through the points (4,-2) and (0,2).
The slope of the line is
The slope of the line is -1.
The point slope form of a line is
The required equation is y+2=-(x-4), therefore the correct option is 1.

Write an equation for the line that is parallel to the given line and that passes through the given point.
y = 5/2x – 10; (–6, –29)
A. y = 5/2x – 14
B. y = -2/5x + 14
C. y = 2/5x – 14
D. y = 5/2x + 133/2
Answer:
A. y = 5/2x – 14
Step-by-step explanation:
Find the slope of the original line and use the point-slope formula y − y 1 = m ( x − x 1 ) to find the line parallel to y = 5 /2 x − 10 .
y = 5 /2 x − 14 PARALLEL
...................................................................................................................................................
Find the negative reciprocal of the slope of the original line and use the point-slope formula y − y 1 = m ( x − x 1 ) to find the line perpendicular to y = 5 /2 x − 10 .
y = − 2 /5 x − 157 /5 PERPENDICULAR
Suppose that a friend missed class and never learned what 25 1/2 means.
Use exponent rules your friend would already know to calculate 25 1/2 X 251/2 .
Explain why this means 25 1/2=5 .
[tex]25^{\frac{1}{2} }[/tex] = 5 because [tex]25^{\frac{1}{2} }[/tex] = √25 and √25 = 5.
Using exponent rule,
[tex]25^{\frac{1}{2} }[/tex] = √25
Any number raised to the power of half (1 / 2), is the same as the square
root of that number. It is represented mathematically as follows:
[tex]a^{\frac{1}{2} }[/tex] = [tex]\sqrt{a}[/tex]
Therefore,
To find that [tex]25^{\frac{1}{2} }[/tex] = 5 can be resolved as follows:
Since [tex]25^{\frac{1}{2} }[/tex] = √25
√25 = 5
Therefore,
[tex]25^{\frac{1}{2} }[/tex] = 5

If f is a linear function where f(-1) = 4 and f(5)=1, find a formula for f(x).
Answer:
f(x) = -0.5x + 3.5
Step-by-step explanation:
f(x) = mx + b
f(-1) = -m + b = 4 ...(1)
f(5) = 5m + b = 1 ...(2)
(1)-(2): -6m = 3 m = -1/2 (-0.5)
b = 4 + (-1/2) = 3.5
Equation: f(x) = -0.5x + 3.5

measures 11cm. Find the measure of the other leg. If necessary, round to the
nearest tenth
Answer:
6.9
Step-by-step explanation:
Use the Pythagorean theorem :
a^2 + b^2 = c^2
so,

Answer:
Part One: $187
Part Two: 11a + 5.5k
Step-by-step explanation:
Part One:
a = 9 (how many adult tickets)
k = 16 (how many kid tickets)
($11 × a) + ($5.50 × k) = total cost
($11 × 9) + ($5.50 × 16)
($99) + ($88) = $187 = total cost
Part Two:
11a + 5.5k
11 is how much the adult ticket costs, you multiply a or the amount of adult tickets in order to get the total cost for adults.
5.5 is how much the kid ticket costs, you multiply k or the amount of kid tickets in order to get the total cost for kids.
you add 11a + 5.5k or the total cost for adults and the total cost for kids to get the total cost.

find the value of x
(x+5)+(5-x)+(x+2)=10
Answer:
x = -2
Step-by-step explanation:
1) Rewrite the equation to remove unnecessary parenthesis: x + 5 + 5 - x + x + 2 = 10
2) Remove the opposite variables: 5 + 5 + x + 2 = 10
3) Calculate the sum of the numbers on the lefthand side: 12 + x = 10
4) Subtract 12 from both sides so that x is by itself: x = 10 - 12
5) Solve the equation on the right, and you get your answer: x = -2
