There are two prominent, nationally circulated newspapers, The Wall Street Journal and USA Today. Among all libraries across the country, 45% subscribe to The Wall Street Journal and 40% subscribe to USA Today, while only 25% subscribe to both The Wall Street Journal and USA Today. If a library is selected at random, what is the probability that it subscribes to The Wall Street Journal but not USA Today?
Answer:
20% = 0.2
Step-by-step explanation:
Let A = Wall Street Journal = 45%
Let B = USA Today = 40%
Let C = Both = 25%
C = A∩B = 25%
The focus is to determine that a random library subscribes to A only
The probability of subscribing to A = 45%
However, there are subscribers to A that are also subsribed to B
This group is C = 25%
To find the probability of subscribing to A only;
Probability of A only = P{A} - P{A∩B} = P{A} - P{C}
P{A} only = 45% - 25% = 20%
P{A} only = 0.2

Which ordered pair is a solution to the system of equations?
A savings account was opened with an initial deposit and never touched again. An account that does not meet the minimum balance requirement is charged a service fee.
Assuming the account was open with an initial deposit below the minimum amount, the current account balance, B, is equal to the product of the initial deposit, I, and the quantity of the difference of 1 and the monthly service fee, f, raised to the power of n, the number of months since the account was open.
If an initial deposit of $2,713.00 is made to the account with a monthly service fee of 5%, what will be the value of B after 13 months? Round to the nearest cent.
To find the current balance B after 13 months with an initial deposit of $2,713.00 and a 5% monthly service fee, you multiply the initial deposit by 0.95 to the power of 13, resulting in a balance of approximately $1,392.64.
Explanation:The student's question involves using a given mathematical formula to find the current balance of a savings account affected by a monthly service fee. The formula provided states that the current balance B is equal to the initial deposit I times the quantity (1 - monthly service fee f) raised to the power of the number of months n. To calculate the current balance after 13 months, given an initial deposit of $2,713.00 and a monthly service fee of 5%, you'd perform the following calculation:
Convert the percentage fee to a decimal: 5% = 0.05.Subtract the service fee from 1: 1 - 0.05 = 0.95.Raise the difference to the power of the number of months: 0.9513.Multiply the result by the initial deposit: $2,713.00 × 0.9513.Using a calculator, this gives:
B = $2,713.00 × (0.9513) ≈ $2,713.00 × 0.5133421 ≈ $1,392.64
Rounded to the nearest cent, the value of B after 13 months is $1,392.64.

There are 52 blades of grass in 2 in2 of lawn. There are 580 blades of grass in 8 in2 of the same lawn. Which equation models the y blades of grass found in x in2 of lawn?
The equation that models the relationship between the number of blades of grass (y) and the area of lawn (x) is y=88x−124. This equation represents the rate of 88 blades per square inch with an initial count of 52 blades.
To find the equation that models the relationship between the number of blades of grass (y) and the area of lawn (x), we can use the given information to form a linear equation.
Step 1: Determine the rate of change. Subtract the initial number of blades from the final number and divide by the change in area: (580 - 52) / (8 - 2) = 528 / 6 = 88 blades per square inch.
Step 2: Write the equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
Step 3: Plug in the slope (m = 88) and one point (x = 2, y = 52) to find the y-intercept:
52 = 88(2) + b
52 = 176 + b
b = -124
Step 4: Write the equation:
y = 88x - 124

Fiona earns $15 for each lawn she mows. Which inequality can be used to find out how many lawns she must mow to earn at least $135?
Final answer:
Fiona needs to mow at least 9 lawns to earn at least $135, represented by the inequality 15L ≥ 135, where L is the number of lawns mowed.
Explanation:
To determine how many lawns Fiona must mow to earn at least $135, we can set up an inequality. Fiona earns $15 for each lawn she mows, therefore if we let L represent the number of lawns mowed, then Fiona's earnings can be represented by 15L. She needs to earn at least $135, so we can write the inequality as 15L ≥ 135. To find L, we divide both sides of the inequality by 15, which gives us L ≥ 9. Therefore, Fiona must mow at least 9 lawns to earn at least $135.

What are the new coordinates of L if parallelogram LMNO is translated down 20 units?
Answer:
The answer is [tex](-4,-19)[/tex]
Step-by-step explanation:
Firstly, we have to determine the coordinates of L before the translation.
If we see the graph, we can see that the coordinate "x" is -4 and the coordinate "y" is 1. So, the original coordinates of L are [tex](4,1)[/tex]
Then, we have to determine the vector of translation. We know that the parallelogram LMNO is translated down 20 units, so it means that it moved only in the negative vertical direction. Then the coordinate of the vector is [tex](0,-20)[/tex]
Finally, in order to determine the new coordinates of L, we have to add the original coordinates of L with the coordinates of the vector of translation, that is:
[tex](-4+0,1-20)\\(-4,-19)[/tex]
So, the new coordinates of L is [tex](-4,-19)[/tex]

4) A sales associate in a department store earns a commission on each suit and each pair of shoes sold. One week, she earned $47 in commission for selling 3 suits and a pair of shoes. The next week, she earned $107 in commission for selling 7 suits and 2 pairs of shoes.
a) Write a system of equations to represent the situation. Explain what your x and y will represent.
b) Solve the system of equations.
c) How much commission does she earn for selling each suit and each pair of shoes?
The sales associate earns a commission of $13 for each suit sold and $8 for each pair of shoes sold, found by solving the system of equations representing her commission earnings for two different weeks.
To represent the sales associate's commission earnings, we will use two variables: let x be the commission for each suit sold, and y be the commission for each pair of shoes sold.
(a) System of Equations:
The first week's commission can be represented by the equation 3x + y = 47. The second week's commission can be written as 7x + 2y = 107.
(b) Solving the System:
Multiply the first equation by 2 to get 6x + 2y = 94.Subtract the first modified equation from the second week's equation: (7x + 2y) - (6x + 2y) = 107 - 94.This simplifies to x = 13, meaning the commission for each suit is $13.Substitute x = 13 into the first equation: 3(13) + y = 47.Solve for y: 39 + y = 47, so y = 8.(c) The commission for each pair of shoes is $8.

How many rectangular faces does a hexagonal pyramid have ?
Samir knows that the volume of prism is 40 cubic units . He also knows that the width can of the prism is 2 units and the height is 5 units. What is the length of the prism?
Final answer:
The length of the prism is 4 units, which is determined by dividing the volume of the prism (40 cubic units) by the product of its width (2 units) and height (5 units).
Explanation:
Samir knows that the volume of a prism is 40 cubic units, the width is 2 units, and the height is 5 units. To find the length of the prism, we can use the formula for the volume of a prism: V = lwh, where V is the volume, l is the length, w is the width, and h is the height. Plugging in the known values, we get 40 = l × 2 × 5. To solve for l, we divide both sides of the equation by the product of the width and height (2 × 5), yielding l = 40 / (2 × 5) = 40 / 10 = 4 units. Thus, the length of the prism is 4 units.
