Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. Suppose there are twice as many student tickets sol
Arada [10]

Answer: 200 adult tickets and 400 student tickets were sold.

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of student tickets that were sold.

Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. If the income from the play was $850, the expression would be

1.75x + 1.25y = 850- - - - - - - - - -1

Suppose there are twice as many student tickets sold as adult tickets. This is expressed as

y = 2x

Substituting y = 2x into equation 1, it becomes

1.75x + 1.25 × 2x = 850

1.75x + 2.5x = 850

4.25x = 850

x = 850/4.25

x = 200

y = 2x = 2 × 200

y = 400

A poll shows that 41% of voters in a city favor of a $0.01 tax increase. If 25 voters are selected at random, what is the probab
DanielleElmas [232]

Answer:

2.6% (Approx)

Step-by-step explanation:

Given:

Number of favor voter = 41% = 0.41

Random selected voters = 25

Exact favor voter = 15

Find:

Probability that exactly 15  will in favor.

Computation:

Number of non-favor voter = 1 - 0.41 = 0.59

Given question is a combination problem.

⇒ ²⁵C₁₅ × 0.41¹⁵ × 0.59¹⁰ =  

⇒ 0.02598130

= 2.6% (Approx)

Find QR. <br> A).12<br> B).-8<br> C).9<br> D).6
mihalych1998 [28]

Answer:

D. 6

Step-by-step explanation:

Let's first find x :-

\sf 3 + 2x + 22 = x + 17

  • \sf 2x + 25 = x + 17
  • \sf 2x - x = 17 - 25
  • \sf x =  - 8

Now that we found x, let's find QR :-

QR = 2x + 22

  • \sf QR = 2( - 8) + 22
  • \sf - 16 + 22
  • \sf 6

Therefore, QR = 6 !!!
