Question

The sum of three numbers is 31. The first number is three times the third number. The sum of the second and third number is one more than the first number. What are the numbers.

Thank You for your time.

Answer #1

The sum of three numbers is−2. The sum of twice the first
number, 3 times the second number, and 4 times the third number
is−15. The difference between 5 times the first number and the
second number is 28. Find the three numbers.(Set up variable(s),
set up equation(s) and then solve the equation(s) to answer the
question.)

The sum of three numbers is 30. One of the numbers is 5 more
than twice a second number and 5 less than the third number. What
are the numbers?

Find two positive numbers satisfying the given requirements. The
product is 27 and the sum of the first plus three times the second

b)using critical numbers and the second derivative test.

Three dice are rolled. What is the probability that number on
first die is less than the positive difference of second and third
die?

2.29 Die rolls. You roll a die three times.
what is the probability the sum of the first two rolls is equal to
the third roll?
3.3 Off to the races. Suppose mike places three
separate bets on three separate tracks. Each bet is for a specific
horse to win. His horse in race 1 wins with probability 1/5. His
horse in race 2 with probability 2/5. His horse in race 3 wins with
probability 3/5. What is the probability...

Suppose two people flip a coin three times. Let X1, X2 denote
the number of tails flipped by the first and second person. Find
the sampling distribution of the sample mean
PLEASE EXPLAIN, I WILL GIVE A THUMBS UP FOR A NICE EXPLANATION.
THANK YOU IN ADVANCE :)

Suppose you toss a fair coin three times. Which of the following
events are independent? Give mathematical justification for your
answer.
A=
{“heads on first toss”}; B=
{“an odd number of heads”}.
A=
{“no tails in the first two tosses”}; B=
{“no heads in the second and third
toss”}.

A fair die is rolled three times. Find the probability that one
or more fours appear given that the sum of the three numbers that
appear is 8.
- Thanks!!
