The 9th graders are selling tickets to raise money for a class field trip. They are selling student tickets for $5 and adult tic

Marina CMI [18]

Answer:

Total number of adult tickets sold = 10

Total Number of Students tickets sold = 30

Step-by-step explanation:

Let $x$ be the number of student tickets sold.

Let $y$ be the number of adult tickets sold.

As per the question statement, total tickets sold are 40.

$x +y =40 ...... (1)$

Price of each student ticket = $5

Sales from students' tickets = Price of each students ticket $\times$ Number of students tickets sold

Sales from student's tickets = 5 $\times x$

Price of each adult ticket = $9

Sales from adult's tickets = Price of each adult's ticket $\times$ Number of adult tickets sold

Sales from student's tickets = 9 $\times y$

Total sales is done by students and adult tickets is $240 as per the question statement.

$\Rightarrow 5x + 9y = 240 ......(2)$

Solving equations (1) and (2) using elimination method:

Equation $(2) - 5 \times (1)$ :

$5x + 9y -5x-5y = 240-200\\\Rightarrow 4y = 40\\\Rightarrow y =10$

Total number of adult tickets sold = 10

Putting $y=10$ in equation (1):

$x+10 = 40\\\Rightarrow x = 30$

Total number of students tickets sold = 30

Total number of adult tickets sold = 10

Total Number of Students tickets sold = 30

In the game of Pick-A-Ball, there are 10 colored balls: 2 red, 4 white, and 4 blue. The balls have been placed into a small buck

MaRussiya [10]

Answer:

The probability of selecting the color of ball that you just selected(a red ball) is $P(r) = \frac{2}{10}$

Step-by-step explanation:

From the question we are told that

The total number of colored balls is n = 10

The number of red balls is r = 2 red

The number of white ball is w = 4

The number of blue balls is b = 4

The number of balls to be selected is N = 2 balls

The cost of playing picking a ball is c = $10

The winnings is $k = \$ P(A)$

Here P(A) is the probability of obtaining the exact sequence of result and from the question it is P(A) = 0.10

Generally my price according to the question is

$k = \frac{0.10 }{10}$

=> $k = 0.01$

Let assume we selected a red ball

Generally the probability of selecting a red ball is mathematically represented as

$P(r) = \frac{2}{10}$
