Explain how the graph would look for the following word problem:

“at midnight, the temperature was 60°. by 2 a. m., the temperature had dropped 18° and stayed there for four hours. two hours later, the temperature had increased by 25°.”

  see attached

Step-by-step explanation:

You are given four time and temperature points:

  (time, temperature) ∈ {(12 am, 60°), (2 am, 42°), (6 am, 42°), (8 am, 67°)}

The graph below shows these plotted, using x=0 as midnight and hours on the horizontal axis. Degrees are on the vertical axis.

Nothing in the problem statement suggests that these points should be connected with straight lines. We have added lines here, partly to show what it means that the temperature stayed the same for 4 hours, and partly to make the temperature points more visible.

A graph of the temperatures given in the problem statement would show the given points with a horizontal lines connecting the points at 2 am and 6 am. You may or may not want to add some connection between the other dots, depending on the expected use of the graph.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
