BB represent the number of bags of avocados that Alonso buys.
Alonso spent all of his money, this confirms that he can buy 3 bags of avocados.
Alonso has $21.00 to spend on eggs and avocados. He buys eggs that cost $2.50, which leaves him with $18.50. Since the store only sells avocados in bags of 3, he will need to find the cost per bag in order to calculate how many bags he can buy.
First, divide the cost of 3 avocados by 3 to find the cost per avocado. $5.00 ÷ 3 = $1.67 per avocado.
Next, divide the money Alonso has left by the cost per avocado to find how many avocados he can buy.
$18.50 ÷ $1.67 per avocado = 11.08 avocados.
Since avocados only come in bags of 3, Alonso needs to round down to the nearest whole bag. He can buy 11 avocados, which is 3.67 bags.
Thus, he will buy 3 bags of avocados.Let's test our answer to make sure that Alonso has spent all his money:
$2.50 for eggs3 bags of avocados for $5.00 per bag, which is 9 bags of avocados altogether. 9 bags × $5.00 per bag = $45.00 spent on avocados.
Total spent:
$2.50 + $45.00 = $47.50
Total money had:
$21.00
Remaining money:

In a bag of 355 chocolate candies, 37 of them are brown. The candy company claims that 13% of its plain chocolate candies are brown. For the following, assume that the claim of 13% is true, and assume that a sample consists of ?? chocolate candies. Complete parts (a) through (e) below.
a. For the chocolate candies, use the range rule of thumb to identify the limits separating numbers of brown chocolate candies that are significantly low and those that are significantly high. (Round to one decimal place)
(1) Values of 37 brown candies or fewer are significantly low.
(2)Values of 37 brown candies or greater are significantly high.
Based on the results, is the result of brown chocolate candies significantly low? Why or why not?
1. Yes, the result of 37 brown candies is less than the second value, so it is significantly low.
2. No, the result of 37 brown candies lies between those limits, so it is neither significantly low nor significantly high.
3. No, the result of 37 brown candies is greater than the second value, so it is significantly high.
4. Yes, the result of 37 brown candies is less than the first value, so it is significantly low.
b. Find the probability of exactly 37 brown chocolate candies. (Round to four decimal places)
The probability is ??.
c. Find the probability of 37 or fewer brown chocolate candies. (Round to four decimal places). The probability is ??
The correct answer is a. 4. Yes, the result of 37 brown candies is less than the first value, so it is significantly low.b. The probability of exactly 37 brown chocolate candies is 0.0306.c. The probability of 37 or fewer brown chocolate candies is 0.0611.
a. According to the range rule of thumb, we can determine the limits for significantly low and significantly high numbers of brown chocolate candies. The rule suggests that values falling outside the range of (mean - 2 * standard deviation) to (mean + 2 * standard deviation) can be considered significantly low or significantly high. In this case:
Let's assume that the sample consists of N chocolate candies.
Given:
Total number of chocolate candies in the bag = 355
Number of brown chocolate candies = 37
Percentage of brown chocolate candies claimed by the company = 13%
We can calculate the mean and standard deviation as follows:
Mean = N * 0.13
Standard Deviation = sqrt(N * 0.13 * 0.87)
Using the range rule of thumb, the limits separating significantly low and significantly high numbers of brown chocolate candies are:
Significantly low: Mean - 2 * Standard Deviation
Significantly high: Mean + 2 * Standard Deviation
b. To find the probability of exactly 37 brown chocolate candies, we can use the binomial probability formula:
P(X = x) = (nCk) * p^k * (1 - p)^(n - k)
In this case, n = N (total number of candies), k = 37 (number of brown candies), and p = 0.13 (probability of a candy being brown).
c. To find the probability of 37 or fewer brown chocolate candies, we need to calculate the cumulative probability from 0 to 37 using the binomial probability formula:
P(X ≤ x) = P(X = 0) + P(X = 1) + ... + P(X = 37)

Bronson Building Inc. is considering a possible investment project, consisting of constructing an office building and then renting it out for use to various local businesses. The initial cost of acquiring the land and constructing the building (first cost) is $21,000,000. The building is expected to be sold for $2,000,000 in 23 years, at the end of the last year of the project. Annual revenue from collecting rents is expected to be $4,000,000, while annual maintenance and operating expenses are projected to equal $2,000,000. Using MARR of 10%, compute the present worth of the project. Note: if the present worth is negative you must include the negative sign with your answer
Answer:The present worth of the project for Bronson Building Inc is $6,389,137.
In order to calculate the present worth, follow these steps:
1. The given information is:
Initial cost (first cost) = $18,000,000
Annual revenue = $5,000,000
Annual expenses = $2,000,000
Net annual cash flow = Annual revenue - Annual expenses = $5,000,000 - $2,000,000 = $3,000,000
MARR = 11%
Project duration = 18 years
Sale price at the end of the project = $8,000,000
2. To calculate the present worth, we first need to find the present value of the net annual cash flows using the MARR as the discount rate. Then, we will add the present value of the sale price and subtract the initial cost.
Present value of net annual cash flows (PV_ACF) = Net annual cash flow * [(1 - (1 + MARR)^(-duration)) / MARR]
PV_ACF = $3,000,000 * [(1 - (1 + 0.11)^(-18)) / 0.11] = $3,000,000 * 7.696 = $23,088,000
3. Find the present value of the sale price at the end of the project.
Present value of sale price (PV_SP) = Sale price / (1 + MARR)^duration
PV_SP = $8,000,000 / (1 + 0.11)^18 = $8,000,000 / 6.146 = $1,301,137
4. Calculate the present worth of the project.
Present worth = PV_ACF + PV_SP - Initial cost
Present worth = $23,088,000 + $1,301,137 - $18,000,000 = $6,389,137

Which system of linear inequalities is represented by the graph?
y > x – 2 and y < x + 1
y < x – 2 and y > x + 1
y < x – 2 and y > x + 1
y > x – 2 and y < x + 1
Answer:
The system of linear inequalities represented by the graph is:
y > x - 2 and y < x + 1
This system of inequalities indicates that y is greater than x - 2, which represents the upper boundary of the shaded region in the graph. Additionally, y is less than x + 1, which represents the lower boundary of the shaded region. The intersection of these two conditions is the region between the lines, satisfying both inequalities.
what steps are needed to find the equation of a line given the graph?
The equation of the line is y = x.
To find the equation of a line given its graph, you need to follow the steps below.
Step 1: Determine the slope of the line.The slope of the line can be determined using the formula: slope = rise/run or m = Δy/Δx. Rise is the change in the y-coordinates and run is the change in the x-coordinates.
Step 2: Determine the y-intercept of the line.The y-intercept is the point where the line intersects the y-axis. You can determine the y-intercept by looking at the point where the line crosses the y-axis on the graph. The y-intercept is denoted by the letter b.
Step 3: Write the equation of the lineThe equation of the line can be written in slope-intercept form, which is y = mx + b. The slope (m) and y-intercept (b) that were determined in steps 1 and 2 are used to substitute into this equation. Thus, the equation of the line becomes y = slope(x) + y-intercept.
Example:Let's say you are given the graph of a line below: .
Step 1: Determine the slope of the line.To determine the slope of the line, you need to choose two points on the line and calculate the rise and run. Let's choose the points (2, 1) and (4, 3). The rise is 2 (3 - 1) and the run is 2 (4 - 2). Therefore, the slope of the line is: m = 2/2 = 1.
Step 2: Determine the y-intercept of the lineThe line crosses the y-axis at the point (0, 0). Therefore, the y-intercept of the line is b = 0.
Step 3: Write the equation of the line.The equation of the line in slope-intercept form is y = mx + b. Substituting the slope and y-intercept into this equation gives: y = 1x + 0 or y = x.

The measure of < HIK is 68.30. If < HIK and < RST are complementary angles, what is the measure, in degrees, of < RST?
Answer:
the measure of < RST is 21.70 degrees.
Step-by-step explanation:
If < HIK and < RST are complementary angles, it means that the sum of their measures is 90 degrees.
Let's denote the measure of < RST as x.
Given that the measure of < HIK is 68.30 degrees, we can set up the following equation:
68.30 + x = 90
To solve for x, we subtract 68.30 from both sides:
x = 90 - 68.30
Calculating the value:
x = 21.70

Debit/Credit: If there are debit or credit transactions on Henry's account, the opposite quantity would depend on whether it is a debit (negative) or credit (positive) entry.
To determine the opposite quantity that makes Henry's balance, we need to know the specific transaction or action that affects the balance. Without further information, it is not possible to provide an exact answer.
However, I can explain a few scenarios based on common banking transactions that could result in an opposite quantity affecting Henry's balance:
1. Withdrawal: If Henry decides to withdraw money from his bank account, the opposite quantity would be the amount he withdraws. For example, if Henry withdraws $50 from his account, the opposite quantity would be -$50.
2. Transfer: If Henry transfers money from his account to another account, the opposite quantity would be the amount of the transfer. For instance, if Henry transfers $100 to another account, the opposite quantity would be -$100.
3. Debit/Credit: If there are debit or credit transactions on Henry's account, the opposite quantity would depend on whether it is a debit (negative) or credit (positive) entry.

The expression 3x² + 6x + 4x + 8 is factorized as (x + 2)(3x + 4).
To factorize the algebraic expression 3x² + 6x + 4x + 8, you can follow these three steps:
Step 1: Grouping
Group the terms in pairs based on their common factors:
(3x² + 6x) + (4x + 8)
Step 2: Factor out common factors
Factor out the greatest common factor from each group of terms:
3x(x + 2) + 4(x + 2)
Now, we have a common factor of (x + 2) in both terms.

Determine if (4,1) is a solution for the system of equations. Explain answer
y = -x + 5
y = 2x - 7
Answer:
Step-by-step explanation:
To determine if the point (4,1) is a solution for the system of equations, we need to substitute the values of x and y from the point into both equations and check if the equations hold true.
For the first equation, y = -x + 5, we substitute x = 4 and y = 1:
1 = -(4) + 5
1 = -4 + 5
1 = 1
The equation holds true for the first equation.
For the second equation, y = 2x - 7, we substitute x = 4 and y = 1:
1 = 2(4) - 7
1 = 8 - 7
1 = 1
The equation also holds true for the second equation.
Since the point (4,1) satisfies both equations, it is indeed a solution to the system of equations.
what best describes the relationship between the computed mean of 52.4 and the actual mean of 52.7
The computed mean of 52.4 and the actual mean of 52.7 suggest a close relationship in terms of central tendency.
A computed mean is a statistical measure calculated by summing up a set of values and dividing by the number of observations. In this case, the computed mean of 52.4 implies that when the values are averaged, the result is 52.4.
The actual mean of 52.7 refers to the true average of the population or data set being analyzed. Since it is higher than the computed mean, it indicates that the sample used for computation might have slightly underestimated the true population mean.
However, the difference between the computed mean and the actual mean is relatively small, with only a 0.3 unit discrepancy.
Given the proximity of these two values, it suggests that the computed mean is a reasonably accurate estimate of the actual mean.
However, it's important to note that without additional information, such as the sample size or the variability of the data, it is difficult to draw definitive conclusions about the relationship between the computed mean and the actual mean.

How would you describe the difference between the graphs of f (x) = 3x²
and g(x) = -2² ?
OA. g(x) is a reflection of f(x) over the line y = x.
B. g(x) is a reflection of f(x) over the line y = -1.
C. g(x) is a reflection of f(x) over the x-axis.
D. g(x) is a reflection of f(x) over the y-axis.
Comparing the characteristics of the two functions, we can conclude that the graph of g(x) = -2² is a reflection of the graph of f(x) = 3x² over the x-axis (option C).
The given functions are f(x) = 3x² and g(x) = -2².
To understand the difference between their graphs, let's examine the characteristics of each function individually:
Function f(x) = 3x²:
The coefficient of x² is positive (3), indicating an upward-opening parabola.
The graph of f(x) will be symmetric with respect to the y-axis, as any change in x will result in the same y-value due to the squaring of x.
The vertex of the parabola will be at the origin (0, 0) since there are no additional terms affecting the position of the graph.
Function g(x) = -2²:
The coefficient of x² is negative (-2), indicating a downward-opening parabola.
The negative sign will reflect the graph of f(x) across the x-axis, resulting in a vertical flip.
The vertex of the parabola will also be at the origin (0, 0) due to the absence of additional terms.
Comparing the characteristics of the two functions, we can conclude that the graph of g(x) = -2² is a reflection of the graph of f(x) = 3x² over the x-axis (option C). This means that g(x) is obtained by taking the graph of f(x) and flipping it vertically. The reflection occurs over the x-axis, causing the parabola to open downward instead of upward.
Therefore, the correct answer is option C: g(x) is a reflection of f(x) over the x-axis.

Compound interestThe value of the investment of principal amount P at interest rate r compounded n times per year for t years is given by the formula ...
A = P(1 +r/n)^(nt)
ApplicationUsing the given values, we find the amount of money in 18 years will be ...
A = $20,000(1 + 0.08/2)^(2·18) = $20,000(1.04^36) ≈ $82,078.65
In 18 years there will be $82,078.65.

Answer:
x ≈ 77.79 ft
Step-by-step explanation:
using the sine ratio in the right triangle
sin40° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{50}{x}[/tex] ( multiply both sides by x )
x × sin40° = 50 ( divide both sides by sin40° )
x = [tex]\frac{50}{sin40}[/tex] ≈ 77.79 ft ( to the nearest hundredth )
