What is the equation of this trend line?<br><br> Enter your answers by filling in the boxes.

zhuklara [117]

Answer:

$k=-2j+24$

Step-by-step explanation:

Take two points from the graph

(0,24) and (6,12)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{k2-k1}{j2-j1}$

substitute

$m=\frac{12-24}{6-0}$

$m=\frac{-12}{6}=-2$ ---> is negative because is a decreasing function

Find the equation of the line in slope intercept form

$k=mj+b$

we have

$m=-2\\b=24$

Note: The y-intercept is given (0,24)

substitute

$k=-2j+24$

jeka57 [31]

Answer:

a. 3/4

b. 1/2

c. 5/6

Step-by-step explanation:

From the question, We are given that:

4 different colours, 3 different font types, 5 sizes, 3 images, 5 text phrases.

If event A is the event that the design color is red, then:

P(A) = 1/4

P(A') = 1 - 1/4 = 3/4.

If event B is the event that the font size is not the smallest one, then:

P(B) = 2/3

P(B')= 1 - 2/3 = 1/3.

P(AnB) = 1/4 * 2/3 = 2/12=1/6

P(AnB')=1/4 * 1/3 = 1/12

P(A'nB') = 3/4 * 1/3=1/4

Solving the questions,

a. P(AuB) = P(A) + P(B) - P(AnB)

P(AuB) =(1/4) + (2/3) -(1/6)

P(AuB) = 9/12

P(AuB) = 3/4

b. P(AuB') = P(A) + P(B') - P(AnB')

P(AuB') = 1/4 + 1/3 - 1/12

P(AuB') = 6/12

P(AuB') = 1/2

c. P(A'uB') = P(A') + P(B') - P(A'nB')

P(A'uB') = 3/4 + 1/3 - 1/4

P(A'uB') = 10/12

P(A'uB')=5/6
