Krystal's school is selling tickets to annual talent show.On the first day of the ticket sales the school sold 4 senior citizen
bogdanovich [222]

Answer:

<u>$4</u> is the price of a citizen ticket and <u>$3</u> is the price of a student ticket.

Step-by-step explanation:

Given:

Krystal's school is selling tickets to annual talent show.

The total ticket sold on the first day is 4 senior citizen tickets and 3 student tickets for a total of $25.

Now, to find the price of the student ticket and the price of the citizen ticket.

<u><em>Let the price of a citizen ticket be </em></u>x.<u><em /></u>

<u><em>Let the price of a student ticket be </em></u>y.<u><em /></u>

So, the total amount of the first day of the ticket sales:

4x+3y=25\ \ \ ....(1)

According to question:

The total amount of the second day of the ticket sales:

4x+14y=58\ \ \ \ .....(2)

Now, using the elimination method we solve the equation:

So, subtracting equation (1) from equation (2):

4x+14y-(4x+3y)=58-25\\\\4x+14y-4x-3y=58-25\\\\11y=33

<em>Dividing both sides by 11 we get:</em>

y=3.

<u>The price of a student ticket = $3.</u>

Now, substituting the value of y in equation (1) we get:

4x+3y=25\\\\4x+3\times 3=25\\\\4x+9=25\\\\Subtracting\ both\ sides\ by\ 9\ we\ get:\\\\4x=16\\\\Dividing\ both\ sides\ by\ 4\ we\ get:\\\\x=4.

<u>The price of a citizen ticket = $4.</u>

Thus, $4 is the price of a citizen ticket and $3 is the price of a student ticket.

Mandarinka [93]
<h2>Answer with explanation:</h2>

Consider a sampling distribution with p equals 0.12 and samples of size n each.

Then, formula for mean = p

Formula for standard deviation= \sqrt{\dfrac{p(1-p)}{n}}

(a) For a random sample of size n equals 5000.

Mean = 0.12

Standard deviation= \sqrt{\dfrac{0.12(1-0.12)}{5000}}

\\\\0.00459565011723\approx0.0046

(b) For a random sample of size n equals 1000.

Mean = 0.12

Standard deviation= \sqrt{\dfrac{0.12(1-0.12)}{1000}}

\\\\=0.0102761860629\approx0.0103

(c) For a random sample of size n equals 500.

Mean = 0.12

Standard deviation= \sqrt{\dfrac{0.12(1-0.12)}{500}}

\\\\=0.0145327216997\approx0.0145
