Using proportions, it is found that:

a. The equations are related to the stories as follows:

b. The parenthesis is because of the 10% reduction was applied over the value subtracted by $20.

c. The solutions are given as follows:

A proportion is a fraction of a total amount, and are used along with basic arithmetic operations such as multiplication or division to find the desired measures in the context of a problem.

One example of application of proportions is for percentage problems, as the decimal equivalent of the percentage, considering discounts or increases, is multiplied by the total amount to find the equivalent amount.

For the college class, we have that:

The equivalent amount is of 830 students, hence the equation is:

0.9x + 20 = 830

The solution is found as follows:

0.9x = 810

x = 810/0.9

x = 900.

Which is the size of the freshmen class in the previous year.

For the computer in the store, we have that:

This price is of 830, hence the equation is:

0.9(x - 20) = 830

The solution, which is the initial price of the computer, is found as follows:

x - 20 = 830/0.9

x = 20 + 922

x = 942.

Step-by-step explanation:

Answer:

3.Events A and B are not independent because P(A|B) ≠ P(A).

Step-by-step explanation:

Given this information, which statement is true?

1.Events A and B are independent because P(A|B) = P(A).

2.Events A and B are independent because P(A|B) ≠ P(A).

3.Events A and B are not independent because P(A|B) ≠ P(A).

4.Events A and B are not independent because P(A|B) = P(A).

Solution:

Two events A and B are independent if A occurring does not change the probability of B. For independent events:

P(A ∩ B) = P(A) * P(B)

Hence: P(A/B) = P(A ∩ B) / P(B) = P(A) * P(B) / P(B) = P(A)

Let event A represent the probability that roger wins a tennis tournament and event B represent the probability that Stephan wins a tennis tournament.

Therefore:

P(A) = 0.45, P(B) = 0.4

The probability of Roger winning the tournament, given that Stephan wins, is 0. Hence, P(A/B) = 0

P(A/B) = P(A∩B) / P(B)

0 = P(A∩B) / 0.4

P(A∩B) = 0

The probability of Stephan winning the tournament given that Roger wins, is 0. Hence P(B/A) = 0

P(B/A) = P(B∩A) / P(A)

0 = P(B∩A) / 0.4

P(B∩A) = 0

Therefore since P(A∩B) = P(B∩A) =0, this means that event A and event B are mutually exclusive. That is both events cannot occur at the same time.

Events A and B are not independent because P(A|B) ≠ P(A).

Answer:

1293 soccer books

Step-by-step explanation:

The tricky part about questions like this is: how do I assign variables to the three types of book?

You get a clue from the sentence, "She sold 3 times as many copies of the soccer book as the baseball book."  The number of soccer books is being described by referring TO the number of baseball books.  Pick a variable and assign it to the item being REFERRED TO!

x = number of baseball books

Then  3x = number of soccer books.  The number of basketball books is the same, so 3x = number of basketball books.  Here's the list...

x = number of baseball books

3x = number of soccer books

3x = number of basketball books

The total of these is 3017, so

x + 3x + 3x = 3017

7x = 3017

x = 431

Ah!  But don't forget to look back at the question:  it asks for the number of SOCCER books!  That's 3x, so 3(431) = 1293.

Answer:

g=4

Step-by-step explanation:

Move all terms not containing g to the right side of the equation.

-7g-2=-30

-7g=-28

g=-28/-7

g=4

hi ^^

---------

Here's your answer: g=4

-----------------------------------

Now the steps: Equation: −7g−2=−30

· Add 2 to both sides.

−7g=−30+2

· Add −30 and 2 to get −28.

−7g=−28

· Divide both sides by −7.

g=   −7 /−28

· Divide −28 by −7 to get 4.

g=4

Answer:

Jaime = 11

Sammy = 44

Step-by-step explanation:

It is given that Sammy is eleven less than five times Jaime's age. Use parameter (S) to represent Sammy's age, and parameter (J) to represent Jaime's age. Form an equation based on this given information:

S = 5J - 11

It is given that the sum of the two girl's ages is (55), use an equation to represent this.

S + J = 55

Substitute in the expression for the value of (S) in terms of (J),

(5J - 11) + J = 55

Simplify,

6J - 11 = 55

Inverse operations,

6J - 11 = 55

6J = 66

J = 11

Backsolve for the value of (S), substitute in the value of (J) into the equation for (S) and solve,

S = 5(J) - 11

S = 5(11) -11

S = 55 - 11

S = 44
