30/78 simplified is 15/39
Answer:

Step-by-step explanation:
We have
square with sides <em>s = 3cm</em>
four triangles with base <em>b = 3cm</em> and height <em>h = 9cm</em>.
The formula of an area of a square:

The formula of an area of a triangle:

Substitute:

The Surface Area:

The probability that the selected consumer is 35–55 years old or likes Crunchicles is 0.444.
Number of people who liked Crunchicles = 121
Number of people who are 35 - 55 years of age = 120
Number of people who are 35-55 years of age or like crunchicles = 121 + 120 - 19
The probability that the selected consumer is 35–55 years old or likes Crunchicles = 222/500 = 0.444.
Make it into y = mx + b
2y = -3x + 6
Divide by 2
Y = -3/2x + 3
The slope is -3/2
