You need to find x and y intercept
y = 1.25x - 2.5

x intercept y = 0 x =2.5/1.25 = 2
y intercept x = 0 y = -2.5

so your coordinates (0,-2.5)(2,0)

answer is A. (first graph)

A city has 20 radio stations including 5 college stations. What is the probablility that a randomly chosen radio station in this
densk [106]

Answer:

1/4

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

the probability that a randomly chosen radio station in this city is a college radio station = number of college stations / total number of city radio stations

= 5/20

To transform to the simplest form. divide both the numerator and the denominator by 5

= 1/4

<em>V = 120 in^3</em>

<u><em>Here is why:</em></u>

The volume formula for a pyramid is:

V=\frac{1}{3}Bh

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.

The area formula for a triangle is:

A=\frac{1}{2}bh

Plug in the numbers.

A=\frac{1}{2}*9*10

A = 45

Now we have found the area of B, we can plug it into the volume formula for the pyramid.

V=\frac{1}{3}*45*8

V = 120 in^3
