The admission fee at a small fair is $1.50 for children and $4.00 for adults. On Saturday, 1000 people entered the fair and $255

miss Akunina [59]

Answer:

Number of children tickets sol= 580

Number of adults tickets sol= 420

Step-by-step explanation:

First, we establish a system of equations:

1.5*x + 4*y= $2,550

x + y = 1,000

x= number of tickets for children sold

y= number of tickets for adults sold

Now, we determine the value of x in one equation and substitute in the other:

x= 1,000 - y

1.5*(1,000 - y) + 4y = 2,550

1,500 - 1.5y + 4y = 2,550

2.5y = 1,050

y= 420

x= 1,000 - 420

x= 580

Number of children tickets sol= 580

Number of adults tickets sol= 420

Prove:

1.5*580 + 4*420= $2,550

580 + 420 = 1,000

Type the correct answer in each box. The sum of a number and two times a smaller number is 62. Three times the bigger number exc

Zielflug [23.3K]

Answer:

Bigger number = 42

Smaller number = 10

Step-by-step explanation:

Step 1: Define variables

x = larger number

y = smaller number

Step 2: Write systems of equations

x + 2y = 62

3x = y + 116

Step 3: Rewrite 1st equation

x = 62 - 2y

Step 4: Substitution

3(62 - 2y) = y + 116

186 - 6y = y + 116

186 = 7y + 116

70 = 7y

y = 10

Step 5: Plug in y to find x

x + 2(10) = 62

x + 20 = 62

x = 42

The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,0

kobusy [5.1K]

Answer:

4.43

Step-by-step explanation:

Given :The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,034 games played

To Find : What is the expected number of wins for the that upcoming month?

Solution :

The probability that the San Jose Sharks will win is 0.3694

Let X = number of games won

Total no. of games = 12

We are supposed to find the expected number of wins for the that upcoming month

So, expected number of wins = E(X)=XP(X)= $12 \times 0.3694 =4.43$

Hence the expected number of wins for the that upcoming month is 4.43
