The table below shows a pattern in the cost of renting a car based on the number of days rented. Car Rentals Number of Days (d)
andrezito [222]

The linear equation that describes the pattern in the cost of renting a car is given by:

  • D. c = 34d + 25

<h3>What is a linear function? </h3>

A linear function is modeled by:

y(x) = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem:

  • For each day, the cost of renting a car increases by 34, hence, the slope is of 34, and the equation is:

c(d) = 34d + b

When d = 4, c = 161, and this is used to find b.

c(d) = 34d + b

161 = 34(4) + b

b = 25

Hence, the equation is c = 34d + 25, and option D is correct.

The fuel tank of a certain airplane can hold up to 400 gallons of fuel. Let W be the total weight of the airplane (in pounds). L
Lady bird [3.3K]
A reasonable function is W = 7F + 5000


Where W is the weight of the plane and F is the number of gallons of fuel.


The domain is the set of possible values for F. That is from 0 (empty tank) to 400 (full tank).


So the domain is F = [0,400], or what is equivalente 0 ≤ F ≤ 400.


The range is the set of values of W.


The minimum value of W is when F = 0 => W = 7(0) + 5000 = 5,000.


The maximum value of W is when F = 400 => W = 7(400) + 5000 = 7,800 


So the range is W = [5,000 ; 7,800], pr 5000 ≤ W ≤ 7,800.

A population is normally distributed with µ = 100 and σ = 10. a sample of size 9 is selected. the probability that an individual
ASHA 777 [7]
A) The empirical rule tells you the probability of being within 1 standard deviation of the mean is 68%.

b) The probability that the sample mean falls within 3 standard deviations* of the mean is 99.7%.

___
* The standard deviation of the sample mean is 1/√9 = 1/3 of the standard deviation of an individual sample. Hence the same limits (90-110) now cover 3 standard deviations of the sample mean.
