Gina is comparing the membership fees for two museums. The art museum charges a one-time fee of $7.25 plus $3.50 per month. - Th
raketka [301]

Answer:

<em>here two links for your answer. https://quizlet.com/325167814/financial-math-flash-cards/ https://quizlet.com/475135130/financial-math-e2020-flash-cards $2.5</em>

<em></em>

<em>Step-by-step explanation:</em>

<em></em>

<em>The art museum charges a one-time fee of $8.25 plus $2.25 per month.</em>

<em></em>

<em>So, the cost function for membership for x months in the art museum f(x) = 8.25 + 2.25x .............. (1)</em>

<em></em>

<em>Again, the science museum charges a one-time fee of $10.75 plus $3.5 per month.</em>

<em></em>

<em>Hence, the cost function for membership for x months in the science museum g(x) = 10.75 + 3.5x ........... (2)</em>

<em></em>

<em>So, from both the equations it is clear that for only joining the monthly charges are zero.</em>

<em></em>

<em>So, f(0) = 8.25 and g(0) = 10.75.</em>

<em></em>

<em>Therefore, Barrett will save by joining the art museum instead of the science museum by $(10.75 - 8.25) = $2.5. (Answer)</em>

Visa Card USA studied how frequently young consumers, ages 18 to 24, use plastic (debit and credit) cards in making purchases (A
umka2103 [35]

Answer:

Given the consumer is 18 to 24 years old, there is 37% probability that he uses a plastic card.

Step-by-step explanation:

This can be formulated as the following problem:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

P = \frac{P(B).P(A/B)}{P(A)}

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

In this problem, we have:

What is the probability of the consumer using a plastic card, given that the consumer is 18 to 24 years old.

The problem states that the probability that a consumer uses a plastic card when making a purchase is .37, so P(B) = 0.37

P(A/B) is the probability that the consumer being 18 to 24 years old, given that he uses a plastic card. The problem states that this probability is .19. So P(A/B) = 0.19

P(A) is the probability that the consumer is 18 to 24 years old. There is a .81 probability that the consumer is more than 24 years old. So there is a .19 probability that he is 18 to 24 years old. So P(A) = 0.19

The probability is

P = \frac{P(B).P(A/B)}{P(A)} = \frac{0.37*0.19}{0.19} = 0.37

Given the consumer is 18 to 24 years old, there is 37% probability that he uses a plastic card.

Which relations are functions?<br><br><br><br> Choose all answers that are correct.
-Dominant- [34]
Hello!

In a function, each input has only one output. In A, three has two outputs, 4 and 5, so A is not a function.

In B, you can use something called the vertical line test to see if each x value has one y value as an output. You move an imaginary vertical line across the graph, and if it intersects with two points it is not a function. If we do this on our graph, it will not intersect two points. Therefore, B is a function.

In C, we can see that each input has one output, or there are all different inputs, so C is a function.

For D we can use that vertical line test again. It intersects both the points (-1,1) and (-1,6) so D is not a function

Our final answers are B and C.


I hope this helps!
