music: 37 min.
if lenny chooses a time of day at random to turn on the radio to his favorite station, what is the probability that the news will be on?
a of the trapezoid.

There is a 32% chance the news is on

Step-by-step explanation:

1. Add up all the times

    19+4+37= 60

2. Take the amount of time the news is on and divide it by the total time to find the probability that is news be on.

    19/60= .31666667

3. Get the percent from the decimal

    32%

11

step-by-step explanation:

32.50-7.50=25

225/25=11

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
