Find the range f(x) =-2x-5 for the domain (-2,-1,1,2).

iVinArrow [24]

Answer:

{ - 9, - 7, - 3, - 1 }

Step-by-step explanation:

To obtain the range substitute the values of x from the domain into f(x)

f(- 2) = - 2(- 2) - 5 = 4 - 5 = - 1

f(- 1) = - 2(- 1) - 5 = 2 - 5 = - 3

f(1) = - 2(1) - 5 = - 2 - 5 = - 7

f(2) = - 2(2) - 5 = - 4 - 5 = - 9

range is { - 9, - 7, - 3, - 1 }

Tommy is thinking about entering a contest at the local gas station. Some of Tommy’s

Ede4ka [16]

Answer:

(a)1 out of 4.

(b)27%

Step-by-step explanation:

Tommy’s probability of winning is given as 0.27.

(a)Ratio Form

$0.27=\frac{27}{100} =27:100\\$Divide both sides of 27:100 by 27\\This gives:\approx 1:4$

Therefore, the probability that Tommy will win is <u>1 out of 4.</u>

(b)Exact Percent Value

Multiply the probability by 100 to obtain the exact percent value.

0.27 X 100=27%

(c)Probability that Tommy will not win.

Probability that Tommy will win+Probability that Tommy will not win=1

0.27+Probability that Tommy will not win=1

Probability that Tommy will not win=1-0.27

Probability that Tommy will not win=0.73
