The profit made id each sign is sold for $20 is $4460

The profit model, P(x) = -10x² + 498x - 1,500

Where, x = price per sign sold

If the price per sign sold is $20. Hence, x = $20

The profit made can be calculated thus :

Put x = 20 in the profit function :

P(20) = -10(20)² + 498(20) - 1,500

P(20) = - 10(400) + 9960 - 1500

P(20) = - 4000 + 9960 - 1500

P(20) = $4,460

The profit made is $4,460

The value of t on solving the equations r + t = r and r − t = − s is 0 and s + r so, option C is correct.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given:

r + t = r and r − t = − s

Calculate the value of t  as shown below,

t = r - r   (Transform the equation as shown)

t = 0

-t = -s - r

t = s + r

Thus, the value of t can be 0 and s + r.

The sum of adjacent angles equals 180 degrees. Opposite angles are equal, so if you know the value of one angle, its opposite partner will have the same value. For example, if the value of one angle is 75 degrees its adjacent angle will be 105 degrees and its opposite angle will also be 75 degrees.

Answer:

[tex]P(Same\ Bill) = \frac{1}{3}[/tex]

[tex]P(Second<First\ Bill) = \frac{1}{3}[/tex]

[tex]P(Both\ Even) = \frac{1}{9}[/tex]

[tex]Pr(One\ Odd) = \frac{4}{9}[/tex]

[tex]P(Sum < 10) = \frac{1}{3}[/tex]

Step-by-step explanation:

Given

[tex]Bills: \$1, \$5, \$10[/tex]

[tex]Selection = 2\ bills[/tex]

The sample space is as follows:

This implies that we construct possible outcome that Ebony selects a bill, returns the bill and then select another.

This means that there are possibilities that the same bill is selected twice.

So, the sample space is as follows:

[tex]S = \{(1,1), (1,5), (1,10), (5,1), (5,5), (5,10), (10,1), (10,5), (10,10)\}[/tex]

[tex]n(S) = 9[/tex]

Solving (a): [tex]P(Same\ Bill)[/tex]

This means that the first and second bill selected are the same.

The outcome of this are:

[tex]Same = \{(1,1),(5,5),(10,10)\}[/tex]

[tex]n(Same\ Bill) = 3[/tex]

The probability is:

[tex]P(Same\ Bill) = \frac{n(Same\ Bill)}{n(S)}[/tex]

[tex]P(Same\ Bill) = \frac{3}{9}[/tex]

[tex]P(Same\ Bill) = \frac{1}{3}[/tex]

Solving (a): [tex]P(Second < First\ Bill)[/tex]

This means that the second bill selected is less than the first.

The outcome of this are:

[tex]Second < First = \{(1,5), (1,10), (5,10)\}[/tex]

[tex]n(Second < First) = 3[/tex]

The probability is:

[tex]P(Second<First\ Bill) = \frac{n(Second<First\ Bill)}{n(S)}[/tex]

[tex]P(Second<First\ Bill) = \frac{3}{9}[/tex]

[tex]P(Second<First\ Bill) = \frac{1}{3}[/tex]

Solving (c): [tex]P(Both\ Even)[/tex]

This means that the first and the second bill are even

The outcome of this are:

[tex]Both\ Even = \{(10,10)\}[/tex]

[tex]n(Both\ Even) = 1[/tex]

The probability is:

[tex]P(Both\ Even) = \frac{n(Both\ Even)}{n(S)}[/tex]

[tex]P(Both\ Even) = \frac{1}{9}[/tex]

Solving (e): [tex]P(Sum < 10)[/tex]

This question has missing details.

The correct question is to determine the probability that, the sum of both bills is less than 10

The outcome of this are:

[tex]One\ Odd = \{(1,10), (5,10), (10,1), (10,5)\}[/tex]

[tex]n(One\ Odd) = 4[/tex]

The probability is:

[tex]Pr(One\ Odd) = \frac{n(One\ Odd)}{n(S)}[/tex]

[tex]Pr(One\ Odd) = \frac{4}{9}[/tex]

Solving (d): [tex]P(One\ Odd)[/tex]

This question has missing details.

The correct question is to determine the probability that, exactly one of the bills is 0dd

The outcome of this are:

[tex]Sum < 10 = \{(1,1), (1,5), (5,1)\}[/tex]

[tex]n(Sum < 10) = 3[/tex]

The probability is:

[tex]P(Sum < 10) = \frac{n(Sum < 10)}{n(S)}[/tex]

[tex]P(Sum < 10) = \frac{3}{9}[/tex]

[tex]P(Sum < 10) = \frac{1}{3}[/tex]

Answer:

About 8014 subscriptions.

Step-by-step explanation:

We can write an exponential function to model the situation.

The standard form of an exponential function is given by:

[tex]f(x)=a(r)^x[/tex]

The current newspaper subscriptions is 15,895. So, a = 15895.

It has been decreasing at a rate of 12.8% each year.

In other words, the number of subscriptions next year will be 100% - 12.8% = 87.2% or 0.872 of the previous year. Thus, r = 0.872.

So, our function is:

[tex]f(x)=15895(0.872)^x[/tex]

Where x is the time that has passed in years.

So the number of newspaper subscriptions after five years will be:

[tex]f(5)=15895(0.872)^5\approx8014\text{ subscriptions}[/tex]

Answer:

9/38

Step-by-step explanation:

The odds of your drawing an even card from the deck are 10/20, or 1/2. The odds of your friend also taking an even card after (WITHOUT recplacing the card) is 9/19, which cannot be further simplified. You multiply the two -- 1/2 * 9/19 -- which results in your answer, 9/38. This is a dependent probability.
