Answer:
4
Step-by-step explanation:
Change the division sign to a multiplication sign and flip 1/8.
check the picture below.
namely, which of those intervals has the steepest slope, recall slope = average rate of change.
now, from the picture, notice, those two there are the steepest, the other three are leaning too much to the "ground".
so, from those two, which is the steepest anyway? let's check their slope.

Answer:
x=2
Step-by-step explanation:
5x +(3-1) =12
5x +2 =12
5x =12-2
5x =10
x =10÷5
x =2
Answer:
<em>12.5%</em>
Step-by-step explanation:
<u>Probabilities</u>
When flipping three fair coins, we can get the following events, being H=Heads, T=Tails

We are looking for the probability of only one specific outcome: THT. The probability to get exactly that combination one out of 8 possible results, that is

The probability to get a tail on the first flip, a head on the second flip, and another tail on the third flip is 12.5%
