Answer:

The range of g(x) = -2x + 33 is D. (Negative infinity, positive infinity)

Step-by-step explanation:

The function g(x) is a linear line, so all values of x are included in the domain. If all values of x in the domain works, then there are infinite amount of values for both x and y. Therefore, your answer is D.

What is the solution to the system of equations below?
polet [3.4K]

Answer:

X = 4 & Y = 3

Step-by-step explanation:

1. Multiply the first equation by -2 & Multiply the second equation by 1

-2 (2x+3y=17)

1  (3x+6y=30)  

Becomes:

−4x−6y=−34

3x+6y=30

Add these equations to eliminate y:

−x=−4

2. Then solve −x= −4 for x:

     −x=−4

    -x/−1 = −4/−1

(Divide both sides by -1)

x=4

Now that we've found x, plug it back in to solve for y.

Write down an original equation:

2x+3y=17

Substitute (4) for (x) in 2x+3y=17:

(2)(4)+3y=17

3y+8=17(Simplify both sides of the equation)

3y+8+−8=17+−8(Add -8 to both sides)

3y=9

3y/3 = 9/3

(Divide both sides by 3)

y=3

Which fraction is closest to zero? 8/12, 5/8, 6/10, 2/3
konstantin123 [22]
6/10 is the closest to zero because if you simplify all the fractions you can, then convert them into decimals, you can easily find what is closer to zero:

8/12 = 2/3 = 0.66
5/8 = 0.62
6/10 = 3/5 = 0.60
2/3 = 0.66

0.60 or 6/10 is the smaller number ;))

1. consider a lottery with three possible outcomes: $125 will be received with probability 0.25, $100 will be received with prob
tigry1 [53]

The lottery's anticipated worth is $80.

Given that,

The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.

A) EV=125*.2+100*.3+50*.5=$80

The lottery's anticipated worth is $80.

The expected value is obtained by multiplying each result by its likelihood.

The expected value of the lottery is then calculated by adding up all of these.

This is what we have: ;;

125(0.2) + 100(0.3) + 50(0.5) (0.5)

= 25 + 30 + 25 = $80

B) This is the formula for variance is shown in figure :

So, we can calculate the variance as follows:

.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975

C) A risk-neutral person would pay $80 or less to play the lottery.
