The cost of a dinner is divided equally among 12 diners.Each diner pays $12.50 for his or her portion. what was the cost of the
dinner?
2 answers:
$150
Answer: $150
Step-by-step explanation:
We can simplify 12.50 to 12.5, because the zero is behind the decimal point, and has nothing after it.
We multiply 12.5 (the cost of each portion) by 12 (the amount of portions) to get the total cost. If you are allowed to use a calculator you can just plug in the numbers, as so:
12.5 x 12 = 150
If not, and you need to show work, It'll look like the image I attached.
If you're unsure, you can use division to check your answer.

The probability of getting 3 or more who were involved in a car accident last year is 0.126.
Given 9% of the drivers were involved in a car accident last year.
We have to find the probability of getting 3 or more who were involved in a car accident last year if 14 were selected randomly.
We have to use binomial theorem which is as under:
n
where p is the probability an r is the number of trials.
Probability that 3 or more involved in a car accident last year if 14 are randomly selected=1-[P(X=0)+P(X=1)+P(X=2)]
=1-{}
=1-{1*0.2670+14!/13!*0.9*0.29+14!/2!12!*0.0081*0.2358}
=1-{0.2670+0.3654+0.2358}
=1-0.8682
=0.1318
Among the options given the nearest is 0.126.
Hence the probability that 3 or more are involved in the accident is 0.126.
