Answer:

30 adult's tickets were sold and 7 children's ticket were sold.    

Step-by-step explanation:

We are given the following information in the question:

Cost of Adult's tickets = $8

Cost of Children's ticket = $5

Total money collected = $275

Let x be the number of adult's tickets sold and y be the number of children's ticket sold.

Then, we can write this in the form of equation:

8x + 5y =275

The point (30,7) means that 30 adults ticket were sold and 7 children's ticket were sold.

Putting these value in the equation:

8x + 5y =275\\8\times 30 + 5\times 7 =240 + 35 = 275

which is true.

Thus, 30 adult's tickets were sold and 7 children's ticket were sold.

Answer:

  • 30 adult tickets
  • 7 children's tickets

Step-by-step explanation:

x and y are defined as the numbers of adult's tickets and the number of children's tickets, respectively. So x=30 means 30 adult tickets; y=7 means 7 children's tickets.

Revenue from sales of those numbers of tickets would be $275.

g Use the counting principle to determine the number of elements in the sample space. The possible ways to complete a multiple-c
Lemur [1.5K]

Answer:

(4)^{20}

Step-by-step explanation:

Total number of questions = 20

Possible options for each question = 4

Sample space contains the total number of possible outcomes.

For every question there are 4 possible ways to select an answer. This holds true for all 20 questions. Selecting an answer for a question is independent of other questions/answers,

According to the counting principle, the total number of possible outcomes will be the product of the number of possible outcomes of individual events. Possible outcomes for each of the 20 questions is 4. This means we have to multiply 4 twenty times to find the total number of possible outcomes.

So, the number of elements in the sample space would be:

(4)^{20}

A radioactive substance is decaying exponentially. If there are initially 15 grams of the substance and after 3 hours there are
sukhopar [10]

Answer:

Ok, an exponential decay is written as:

P(t) = A*(1 - r)^t

Where A is the initial population, r is the rate of decay and t is the unit of time.

We know that the initial population is 15g

then:

P(t) = 15g*(1 - r)^t

And at t = 3hs, the populations is 5g

P(5h) = 5g = 15g*(1 - r)^5

5/15 = 1/3 = (1 - r)^5

(1/3)^(1/5) = (1 - r) = 0.8

Now, the half life time of the sustance is t = x, such that the population reduces to it's half:

P(x) = A/2 = 15g/2 = 7.5g

Then:

7.5g = 15g*0.8^x

7.5g/15g = 1/2 = 0.8^x

Now, remember that if we have:

a = b^x

then

x = ln(a)/ln(b)

ln(1/2)/ln(0.8) = x = 3,11 hours
