First, we need to get triple of x:

Triple of x is: 3x

Next is to get the difference between 3x and 13:

x + 3x -13

4x - 13

Hence, the variable expression is 4x - 13

A fair coin is tossed three times in succession. The set of equally likely outcomes is StartSet HHH comma HHT comma HTH comma TH

The probability of getting exactly zero tails is 1/8.

Step-by-step explanation:

When a fair coin is tossed three time, the set of equally likely outcomes is:

S= {HHH,HHT, HTH, THH, HTT, THT, TTH, TTT}

n(S)=8

Let A be the event that there are exactly zero tails which means there are all heads

Then

A= {HHH}

n(A)=1

$P(A)=\frac{n(A)}{n(S)}\\=\frac{1}{8}$

The probability of getting exactly zero tails is 1/8.

First, Mike rounded his number to the nearest ten

146,000 7,000 4,510 27,000 12,500

Then, he rounded his number to the nearest hundred.

146,000 7,000 4,500 27,000 12,500

The phony bologna meat company offers two platters. platter a comes with 4 hamburgers, 3 hot dogs, and 2 pig's feet, and costs $

Brrunno [24]

The solution for this problem is:
If there is 60 platters of B at a cost of $720:
(220 - 60 x 3) / 4 = 10 platters of A to make up for the deficit in hamburgers
(270 - 60 x 4) / 3 = 10 platters of A to make up for the deficit in hot dogs
(250 - 60 x 5) / 2 = 0 platters of A since there is no deficit in pigs feet

So 10 platters A are required at a cost of $150. $720 + $150 = for a total minimum cost of $870.

8+(14+6) FIND EASIER EXPLAIN WHY

alexandr1967 [171]

Hi there and welcome to Brainly!

The answer to 8+(14+6) = 28. The reason for this is you add what is in parenthesis first then you add the number outside of the parenthesis. This follows the PEMDAS rule which is called the order of operations. PEMDAS is an acronym which stands for Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction, this is the order you should follow when solving any problem.

If you have anymore questions please feel free to ask them.
