Answer:

7.5 hours

Step-by-step explanation:

We can model an equation for this problem.

We can write:

F=mt

Where

F is the final temperature (15 degrees we need)

m is the rate of temperature change (2 degrees per hour)

and

t is the time, in hours, it will take (we need to find this)

It is given,

F = 15

m = 2

So, t would be:

F = mt

15 = 2t

t = 15/2 = 7.5

So it will take 7.5 hours

The two spinners below are spun. Find the probability of spinning a 4 and a C.
r-ruslan [8.4K]

Step-by-step explanation:

S = { 1, 2, 3, 4, 5, 6 7, 8 }

n ( S ) = 8

Let A be the event of getting 4,

A = { 4 }

n ( A ) = 1

P ( A )

= n ( A ) / n ( S )

= 1 / 8

Therefore, the probability of spinning a 4 is 1 / 8.

S = { A, B, A, C, A, B }

n ( S ) = 6

Let Y be the event of getting C,

Y = { C }

n ( Y ) = 1

P ( Y )

= n ( Y ) / n ( S )

= 1 / 6

Therefore, the probability of spinning a C is 1 / 6.
