Let x represent the number of adult tickets sold.

Let y represent the number of student tickets sold.

We were told that the movie theater sold a total of 205 tickets to a movie. This means that

x + y = 205

Adult tickets were $9 and student tickets were $5. This means that the cost of x adult tickets and y student tickets is 9x + 5y. If the total cost of the tickets was $1621, it means that

9x + 5y = 1621

From the first equation, x = 205 - y

We would substitute x = 205 - y into 9x + 5y = 1621. Thus, we have

9(205 - y) + 5y = 1621

1845 - 9y + 5y = 1621

- 9y + 5y = 1621 - 1845

- 4y = - 224

y = - 224/- 4

y = 56

x = 205 - y = 205 - 56

x = 149

Thus, 56 student tickets were sold

Evaluate ㏒ b 1, b > 0.
IrinaVladis [17]

Answer:

The solution is 1.

Step-by-step explanation:

Logarithm:

Suppose we have a logarithmic equation in the following format:

\log_{a} b = c

It means that:

a_c = b

In this question:

\log_{b} 1 = x

Which means that:

b^x = 1

Every number, elevated to 0, is 1. So

b^0 = 1

Which means that the solution is x = 1

Answer:

a. Genre with highest mean is drama. Mean is 72.10

B. 10.46 is difference between means of comedy and horror

C. Horror has the lowest minimum value at 25.00

Action and comedy both have the highest maximum value at 93.00

Step-by-step explanation:

First create a table with the data provided like I did in the attachment. It would give a clearer picture of what your answers should be.

1. Which genre has the highest mean score?

From the table, we have the means as:

Action = 58.63

Comedy = 59.11

Drama = 72.10

Horror = 48.65

The genre with the highest score is drama at 72.10

2. Difference in mean score between comedy and horror

Mean of comedy = lc = 59.11

Mean of horror = ly = 48.65

Difference = lc-ly

= 59.11 - 48.65

= 10.46

3. The genre with lowest score is the genre with the lowest minimum value. This genre is horror and the lowest minimum is 25.00

The genre with highest minimum value is that whose maximum value is the highest out of all the genres. Both action and comedy have the highest maximum value at 93.00
