Answer:

Step-by-step explanation:

Population of X is {1, 1, 2, 2, 2, 3, 3, 3}

Based on that, X's expected value, variance and standard deviation can be calculated as follows:

Expected Value, μ = 2.125 or 2.13

Variance, σ2 = 0.609375 0r 0.61

Standard Deviation, σ = 0.78062475 or 0.78

What’s -2y+16=10 plz solve 2 step equation
konstantin123 [22]

Answer:

y=3

Step-by-step explanation:

To solve this 2 step equation, we need to get y alone. Lets write out the equation

-2y+16=10

Subtract 16 from both sides

-2y-16+16=10-16

Subtract

-2y=-6

divide both sides by -2

-2y/-2=-6/-2

divide

y=3

write the equation in standard form of the function with x intercepts at (4,0) and (-2,0) that has been reflected across the x a
Anastaziya [24]

answer

-3x^{2} +6x + 24

explanation

since there are 2 x-intercepts, the lowest degree the function could possibly have is 2, so this could be the graph of a parabola

since our zeros are at x = 4 and x = -2, our factors are (x - 4) and (x + 2)

our equation so far is

(x - 4)(x + 2)

= x^2 -4x + 2x - 8

= x^{2} -2x - 8

since the function is reflected across the x-axis, multiply the equation by -1

-(x^{2} -2x - 8)

= -x^{2} +2x + 8

since the function has a vertical stretch of 3, multiply the equation by 3

3(-x^{2} +2x + 8)

= -3x^{2} +6x + 24
