First, notice that we have the results of 45 surveys, then, if A is the event {the customer is pleased} and B is the evente {the customer purchased a Toes Knows shoes}, then their probabilities are:
\(\begin{gathered} P(A)=\frac{10+7}{45}=\frac{17}{45} \\ P(B)=\frac{3+7+10}{45}=\frac{20}{45} \end{gathered}\)then, the probability that both A and B occur is:
\(P(A\cap B)=P(A)\cdot P(B)=\frac{17}{45}\cdot\frac{20}{45}=\frac{340}{2025}=\frac{68}{405}\)therefore, the probability that a random selected customer is pleased and purchased a Toes Knows shoe is 68/405
use the definition of continuity and the properties of limits to show that the function is continuous at the number a
Continuity is the formulation of a function that varies with no breaks or jumps. The concepts of limits and continuity have been used to show that the function is continuous at the number a below.
If a graph has no holes asymptotes or breaks at any point then the function is said to be continuous. Or if we can draw the function without lifting our pen then it is called continuous.
The conditions which it should satisfy are,
1)The limit must exist at that point.
2) The function must be defined at that point, and
3)The limit and the function must have equal values at that point. So,
A function f(x) is said to be continuous at x=a if,
lim f(x) = f(a)
x→a
A function is said to be continuous on the interval [a,b] if it is continuous at each point in the interval.

A voter in the upcoming election has many different types of issues on the ballot. Of the issues on the ballot, 7 are school related, 10 are ordinance related, and 2 are library related. If a single issue is picked at random, what is the probability that the issue is school or library related?
The probability of randomly picking a school or library-related issue from the ballot is 9/19 or approximately 0.474 (rounded to three decimal places).
To determine the probability of a randomly picked issue being school or library related, you'll need to consider the total number of issues and the number of school and library issues combined.
There are 7 school-related issues, 10 ordinance-related issues, and 2 library-related issues, making a total of 19 issues on the ballot. To find the probability of picking a school or library issue, combine the number of school and library issues: 7 + 2 = 9.
Now, divide the number of school and library issues (9) by the total number of issues (19): 9/19.

is the ordered pair a solution to the equation. y=-7; (-5,6)
Answer: No
To check if (-5,6) is a solution to the equation y=-7, we need to substitute -5 for x and 6 for y in the equation.
If the equation is true, then the ordered pair is a solution to the equation.
If we put (-5,6) into y=-7, we get 6=-7, which is not true.
So, (-5,6) is not a solution to the equation y=-7.
My Truck Takes 50 Gallons of gas. I used 20⅔ gallons on Monday. 9¼ on Tuesday. And 2½ on Wednesday. How many Gallons of gas do i still have in my truck?
Answer:
17 7/12 gallons of gas.
Step-by-step explanation:
Set the fractions to like denominators. It'll make it a hell of a lot easier to add.
20 2/3rds = 20 8/12
9 1/4ths = 9 3/12
2 1/2 = 2 6/12
Adding those together gets you 31 17/12 which is 32 5/12 simplified.
Take that fraction and subtract it from your 50 gallons and it'll get you 17 7/12
Alex found a new black bean soup recipe that calls for tomatoes and black beans. If tomatoes cost $1.60 per pound and black beans cost $1.70 per
pound and the recipe calls for 3 times as many pounds of black beans as tomatoes, at most how many pounds of tomatoes can he buy if he only
has $26.80?
Alex can buy at most 4 pounds of tomatoes
Let:
a represent pounds of tomatoes to buy
3a represent pounds of black beans to buy
Total cost of each ingredient that can be bought = number of pounds x price per pound
Tomatoes = a x $1.60 = 1.60a
Black beans = 3a x $1.70 = 5.1a
1.60a + 5.1a = 26.80
Add similar terms
6.7a = 26.80

Which graph shows the solution to the system of linear inequalities?
2x - 3y <12
y < =2
The solution to the system of linear inequalities is the shaded region that satisfies both inequalities.
We have,
To find the solution to the system of linear inequalities:
2x - 3y < 12
y ≤ 2
We first graph the line 2x - 3y = 12:
To graph the line, we can find the x and y intercepts:
When x = 0, we have -3y = 12, then y = -4, so (0, -4) is a point on the line.
When y = 0, we have 2x = 12, then x = 6, so (6, 0) is a point on the line.
Plot these two points and draw the line passing through them:
Next, we shade the region that satisfies the inequality 2x - 3y < 12:
We can choose a test point not on the line, such as (0,0).
Substitute the coordinates into the inequality:
2(0) - 3(0) < 12, which is true.
Now,
We shade the region that satisfies the inequality y ≤ 2:
We shade the region below the horizontal line y = 2:
Therefore,
The solution to the system of linear inequalities is the shaded region that satisfies both inequalities.

Use implicit differentiation to find dy/dx and d^2y/dx^2.
Using implicit differentiation dy/dx = -(2x + y)/(x + 2y) and d2y/dx² = -2(x² - 3xy - y²)/(x + 2y)³.
Implicit differentiation is the process of differentiating an equation in which it is not easy or possible to express y explicitly in terms of x.
Given the equation x² + xy + y² = 5,
we can differentiate both sides with respect to x using the chain rule as follows:
2x + (x(dy/dx) + y) + 2y(dy/dx) = 0
Simplifying this equation yields:
(x + 2y)dy/dx = -(2x + y)
Hence, dy/dx = -(2x + y)/(x + 2y)
Next, we need to find d^2y/dx^2 by differentiating the expression for dy/dx obtained above with respect to x, using the quotient rule.
That is:
d/dx(dy/dx) = d/dx[-(2x + y)/(x + 2y)](x + 2y)d^2y/dx² - (2x + y)(d/dx(x + 2y))
= -(2x + y)(d/dx(x + 2y)) + (x + 2y)(d/dx(2x + y))
Simplifying this equation yields:
d2y/dx² = -2(x² - 3xy - y²)/(x + 2y)³

Imagine that you need to buy some chicken for dinner tonight. You found an ad showing that the store across town has chicken on sale for $1.59 a pound. Your usual neighborhood store sells the same chicken for $2.89 a pound. Is it worth the extra drive?
Look at the information below you’ll need to solve the problem.
How much chicken will you be buying? 3 pounds
How does the distance and the time it takes to get there, compare between the two stores? Your neighborhood store is 2.1 miles away, and takes about 8 minutes. The store across town is 8.6 miles away, and takes about 24 minutes.
What kind of mileage does your car get? It averages about 22 miles per gallon in the city.
How many gallons of fuel does your car hold? About 13 gallons
How much is gas? About $1.98/gallon right now.
Are there any other pieces of information you need to solve the problem? Which option would you choose? Is going to the further store cheaper? Or is going to the close store cheaper? How much money does the cheaper option save you? Give your answer to the nearest cent.
Answer:
Step-by-step explanation:
Considering the store in your neighborhood, price per pound of chicken is $2.89. The cost of 3 pounds is
3 × 2.89 = $8.67
Distance = 2.1 miles
The car averages about 22 miles per gallon in the city. It means that the number of gallons needed is
2.1/22 = 0.095 gallons
Cost of gas = $1.98/gallon
Cost of 0.095 gallons =
1.98 × 0.095 = $0.1881
Total cost = 8.67 + 0.1881 = $8.86
Considering the store across town, price per pound of chicken is $1.59. The cost of 3 pounds is
3 × 1.59 = $4.77
Distance = 8.6 miles
The car averages about 22 miles per gallon in the city. It means that the number of gallons needed is
8.6/22 = 0.39 gallons
Cost of gas = $1.98/gallon
Cost of 0.39 gallons =
1.98 × 0.39 = $0.77
Total cost = 4.77 + 0.77 = $5.54
Therefore, it is cheaper going to the further store. The amount that the cheaper option saves is
8.86 - 5.54 = $3.32

Which is the inverse of the function f (x) = 1/4x + 1/2
Answer:
f⁻¹(x) = 4x - 2
Step-by-step explanation:
To find the inverse of a function, switch the places of x and y (or f(x)).
f(x) = 1/4x + 1/2 → y = 1/4x + 1/2
Switch the variables.
x = 1/4y + 1/2
Now you want to convert the equation back into y = mx + b form.
x = 1/4y + 1/2
Subtract 1/2 from both sides.
x - 1/2 = 1/4y
Now, you want to isolate y further by dividing both sides by 1/4 (or multiplying by 4).
4(x - 1/2) = y
Distribute the 4.
4x - 2 = y → y = 4x - 2 → f⁻¹(x) = 4x - 2
This is the inverse of your given function.

Explain why.
Answer:
Option B, Area of pentagon = 58.5 Square feet
Step-by-step explanation:
The remaining part of the question is attached as image
Solution
Area of pentagon has a triangle and a trapezoid
Area of triangle = 0.5 *base *height = 0.5*9 *3 = 13.5 square feet
Area of trapezoid = Area of rectangle – 2* area of smaller triangles
= 9 ft * 6ft – ( 2 * 0.5 * 6 ft * (9 ft – 6ft) /2
= 54 – (1*6*1.5)
Area of pentagon = 13.5 + 45 = 58.5 Square feet
Hence, option B is correct
