Answer:

the speed value that the radar equipment outputs.

Step-by-step explanation:

A random variable in an experiment is also (and most times the case) called a dependent variable. In this scenario, the random variable would be the speed value that the radar equipment outputs. This is because this value depends on the actual velocity of the cars that pass by the equipment. The faster the car is moving when it passes the radar the higher value will be displayed on the equipment. Therefore, depending completely on the vehicles.

Given f(x) = 4x4 + 5x3 – 15x2 – 45, find f(–3).
poizon [28]

Answer:

C)  

f(–3) = 9

Step-by-step explanation:

Given f(x) = 4x^4 + 5x^3 – 15x^2 – 45

f(-3) means let x = -3

f(-3) = 4(-3)^4 +5(-3)^3 – 15(-3)^2 – 45

       =4(81) +5(-27) -15(9) -45

        = 324 - 135 - 135 -45

           =9

Which equation represents a line that passes through (5, 1) and has a slope of StartFraction one-half EndFraction?
saul85 [17]

Answer:

y – 1 = y minus 1 equals StartFraction one-half EndFraction left-parenthesis x minus 5 right-parenthesis.(x –5)

Step-by-step explanation:

we know that

The equation of the line into point slope form is equal to

y-y1=m(x-x1)

we have

m=\frac{1}{2}

(5,1)

substitute

y-1=\frac{1}{2}(x-5)

cestrela7 [59]

Answer:

P(t)=25,000(1.12)^t

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

P(t)=a(b)^t

where

P(t) is the population in Madison

t is the number of years

a is the initial value

b is the factor of growth

we have

a=25,000\ people\\b=1.12

substitute

P(t)=25,000(1.12)^t
