SPEED VS. PRICE OF TICKET Speed (MPH) Price of Ticket ($) 25 65 Linear Regression Equation: y=4.671x-279.497 68 37 slope: 72 55 Y-intercept: 88 120 76 82 Predict the price of a ticket if you are driving 85 mph. 90 150 74 64

The predicted price of ticket if driving at 85 mph is $117.538

Step-by-step explanation:

The data points are;

(65, 25 )

(68, 37 )

(72, 55 )

(88, 120)

(76, 82 )

(90, 150)

(74, 64)

The Linear Regression Equation for the given data is; y = 4.671·x - 279.497

Therefore, the price of a ticket if driving at 85 mph is given as follows;

y = 4.671 × 85 - 279.497 = 117.538

The predicted price of ticket if driving at 85 mph = $117.538.

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
