The percent increase in the number of comedy tickets issued per weekend, given the number of tickets issued, can be found to be 90 %

To find the percentage increase, you need to find out the increase in the number of tickets issued between last weekend and this weekend. This difference would then be found as a percentage of the number of tickets sold last weekend.

The increase in tickets sold for comedies is therefore:

= This weekend tickets - Last weekend tickets

= 15, 314 - 8, 060

= 7, 254 tickets

The percentage increase is:

= Increase in tickets sold / Total tickets sold last weekend x 100 %

= 7, 254 / 8, 060 x 100 %

= 0. 90 x 100 %

= 90 %

For the function: y = √(x - 7) - 1

The domain is D: [7, ∞) and the range is R: [1, ∞)

Remember that the for a function y = f(x), the domain is the set of the possible inputs (possible values of x) while the range is the set of the possible outputs (possible values of y).

Here we want to find the domain and range of the function:

y = √(x - 7) - 1

First, we will find the domain, remember that the argument of a square root must be zero or larger, then the minimum of the domain is the value of x such that:

x - 7 = 0

x = 7

The domain is:

D: [7, ∞)

The square root is an increasing function, then the minimum of the range is given by evaluating the function in the minimum of the domain:

f(7) = √(7 - 7) - 1

f(7) = 1

Then the range is:

The Graph C shows the solution to this system of inequalities in the coordinate plane.

When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.

A collection of inequalities for which we consider common solution for all inequalities is called a system of inequalities.

We are given that

3y > 2x + 12

2x + y ≤ - 5

Therefore, solving it;

x < 3(y - 4)  / 2

y > 2 (x + 6)  / 2

2x + y< -5

x> -5

So,

x < 3(y - 4)  / 2  

Here it shows dotted ascending line attached through x=-6

This means x=--6 and y = 0

This x>-5 shows boundary dotted vertical line through -5

Which means x = -5 y = 0

If it had been x ≥ -5 it would have been solid boundary line.

The value of the expression Illustrated as (2a⁴)²/a^0a^5 is C. -500

The exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number

From the information (2a⁴)²/a^0a^5

We know ( xy) ^z = x^z y^z

(2a^4)^2 = 2^2 a^4^2

b. f(f(f(2)) = 1.

c. f(f(g(2))) = 2.

d. g(f(g(4))) = 2.

The numeric value for each expression is obtained using the compositions, and also the numeric values given from the tabke,

Thus the numeric value in item b is obtained as follows:

f(f(f(2)) = f(f(4)) = f(5) = 1.

The numeric value in item c is obtained as follows:

f(f(g(2))) = f(f(5)) = f(1) = 2.

Answer:

$50

Step-by-step explanation:

To find the amount of interest earned in 8 years, we can use the formula:

interest = principal * rate * time

where "principal" is the initial deposit, "rate" is the interest rate, and "time" is the number of years the interest is compounded.

Plugging in the values from the problem, we get:

interest = $250 * 2.5% * 8 years

interest = $250 * 0.025 * 8

interest = $50

So Ernie will earn $50 in interest in 8 years on his initial deposit of $250.

The pairs of equivalent expressions are matched as follows:

Equivalent expressions are expressions that are equal when both are simplified.

For the first expression, we have that:

(-14 + 3b/2) - (1 + 8/2b)

-14 + 3b/2 - 1 - 8/2b

Combining the like terms:

-15 - 5b/2.

For the second expression, we have that:

(5 + 2b) + (2b + 3/2)

5 + 2b + 2b + 3/2

10/2 + 4b + 3/2

4b + 13/2.

For the third expression, we have that:

(7b/2 - 3) - (8 + 6b)

7b/2 - 3 - 8 - 6b

7b/2 - 11 - 12b/2

-5b/2 - 11.

For the fourth expression, we have that:

(-10 + b) + (7b - 5)

The probability of rolling a number less than 4 on a six-sided die, when rolled 20 times, is 0.5.

Probability is the mathematical study of outcomes in uncertain situations. It is used to describe the likelihood of an event occurring, and it can be expressed as a number between 0 and 1. Probability is used to quantify the uncertainty associated with any given event. It helps us understand how likely it is that something will happen, and it can be used to make predictions about future events. Probability theory is a cornerstone of modern statistics and is widely used in fields such as finance, economics, and science.

This is because there are four possible outcomes when rolling a six-sided die, and two of those outcomes are numbers less than 4: 1 and 2. The probability of rolling a number less than 4 is therefore 2/4, or 0.5. This probability holds true regardless of how many times the die is rolled, as long as it is a fair and unbiased die.

The graph of the inequality:

y > (-5/4)*x - 2

Can be seen in the image at the end.

Here we want to graph the following inequality:

y > (-5/4)*x - 2

To graph the inequality, we first need to draw the line:

y = (-5/4)*x - 2

With a dashed line (because the points on the line are not solutions) and then shade all the region above that dashed line.

To graph that line you need to find two points on the line and then connect them.

To find the points, we need to evaluate the line in two values of x.

if x = 0.

y = (-5/4)*0 - 2

y = -2

So we have the point (0, -2)

if x = 4

y = (-5/4)*4 - 2

y = -5 - 2

y = -7

So we have the point (4, -7)
