Answer:

True?

Step-by-step explanation:

Kinda weird description, and also if you flip a coin 50 times you would theoretically get 25 heads. So, you wouldnt draw the conclusions of "1 over 2" from getting 30 heads, because then in the example it is more like 3/5 flips are heads, and 2/5 are tails, which is false because you have a 50/50 chance. Go with true, lemme know what happens.

The temperature has been going down at a constant rate.In 4 hours it went down 12 degrees.Which expression best shows the temper
fomenos

Answer:

<u>t = t₀ - 3n</u>

Step-by-step explanation:

Let t be the temperature and t₀ be the initial temperature of the day

Let n be the number of hours after the initial temperature ( t₀) was registered

Let -3 be the constant of change of temperature ( In 4 hours it went down 12 degrees)

Now, let's write down the expression that shows the temperature change each hour, this way:

t = t₀ - 3n

After 2 hours

t = t₀ - 3 * 2 = t₀ - 6

After 5 hours

t = t₀ - 3 * 5 = t₀ - 15

After 3 hours and 30 minutes

t = t₀ - 3 * 3.5 = t₀ - 10.5
