jeka94

Answer:

(a) 21

(b)2520

Step-by-step explanation:

(a)

Using combination formula, nCr where n is the total sample and r is the limitation hence 7 combination 5.

[tex}7C5=\frac {7*6*5*4*3}{5*4*3*2*1}=\frac {2520}{120}=21[/tex]

(b)

If the scholarships are not equal

The number of ways to select the 5 students from 7 we use permutation formula hence

7P5 = 7*6*5*4*3 = 2520

D. Use the model from part (a) to approximate the mileage of an automobile that costs $15,500.

ahrayia [7]

The linear regression equation which models the data, obtained using technology such as a linear regression calculator is :

y = - 0.18x + 19716.81

x = mileage ; y = price

The predicted or approximate values obtained using the model are given below :

A.)

Approximate mileage for an automobile that costs $15500 can be calculated thus :

y = 15500

Substituting y = 15500 into the equation :

15500 = -0.18x + 19716.81

0.18x = 19716.81 - 15500

0.18x = 4216.81

x = 4216.81 / 0.18

x = 23,426.722

Hence, mileage is about 23427 miles.

B.)

Approximate the predicted price of an automobile with 6000 miles :

x = 6000 miles

Substituting x = 6000 into the equation :

y = -0.18x + 19716.81

y = -0.18(6000) + 19716.81

y = 18636.81

Hence, the price of the car would be about $18637.
