Evaluating multiple companies before making an investment decision helps to make informed decisions, diversify your portfolio, and maximize returns.
It is critical to consider multiple companies before investing because:
Diversification reduces the risk of loss because the performance of one company does not determine the overall performance of your portfolio.
Opportunity Cost: Comparing and selecting the best investment options allows you to avoid missing out on potential higher returns by evaluating multiple companies.
Due Diligence: Investing in a company necessitates extensive research and due diligence. When you look at multiple companies, you can compare financial statements, management, products, and other factors that can affect stock performance.
Finally, evaluating multiple companies prior to making an investment decision allows you to make informed decisions, diversify your portfolio, and maximize returns.

A department store buys 300 shirts at a cost of $1,800 and sells them for $9 each. What is the percent markup? A department store buys 300 shirts at a cost of $1,800 and sells them for $9 each. What is the percent markup?
The percent markup of a department, if they sell 300 shirts at a cost of $9 each is 50%
According to the question, we learn that a department store buys 300 shirts at a cost of $1,800 and sells them for $9 each. This means :
The selling price of 300 shirts = 300 × $9
The selling price of 300 shirts = $2700
Selling price > cost price i.e., 2700 > 1800
when selling price is greater than cost price it means department store made a profit.
Profit = selling price - cost price
Profit = 2700 - 1800 = $900
Profit percentage = profit/ cost price × 100
Profit % =[tex]\frac{900}{1800} \times 100[/tex]
Profit % = 50%

A caterer charges $110 to cater a party for 10 people and $220 for 20 people. Assume the cost, y, is a linear function of the number of x people. Write an equation in slope-intercept form for this function. What does the slope represent? How much would a party for 60 people cost?
The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the cost per people.b is the intercept, representing the fixed cost.Two points on the function are given as follows:
(10, 110) and (20, 220).
The slope is given by the change in the output divided by the change in the input, hence:
m = (220 - 110)/10
m = 11.
Hence:
y = 11x + b.
When x = 10, y = 110, hence the intercept b is given as follows:
110 = 11(10) + b
b = 0.
Hence the function giving the cost for x people is of;
y = 11x.
The cost for 60 people would be of:
y = 11(60)
y = $660.

Marta’s jump rope is 10 inches shorter than three times the length of David’s rope.
If both of their ropes lay together end to end, they measure 120 inches long. How long is each person’s jump rope?
Marta's rope is 10 inches shorter than three times the length of David's rope and they measure 120 inches long together , then Marta's rope is 77.5 inches long and David's rope is 32.5 inches long.
Let's call the length of David's rope x.
According to the problem, Marta's rope is 10 inches shorter than three times the length of David's rope, so we can write an equation for Marta's rope:
length of Marta's rope = 3 * x - 10
And the combined length of both of their ropes is 120 inches, so we can write another equation:
x + (3 * x - 10) = 120
Expanding the second equation and solving for x, we get:
4x - 10 = 120
Adding 10 to both sides:
4x = 130
Dividing both sides by 4:
x = 32.5
So, David's rope is 32.5 inches long.
We can use the first equation to find the length of Marta's rope:
length of Marta's rope = 3 * x - 10 = 3 * 32.5 - 10 = 87.5 - 10 = 77.5 inches
So, Marta's rope is 77.5 inches long.

(a) We have to determine the sample size for the above sample.
The number of participants or observations included in a study is referred to as the sample size. This number is commonly represented by the symbol n.
Sample Size (n) = 15
(b) We have to calculate the sample mean for these data.
Sample Mean = Total Sum of data/Total Number
Sample Mean = (3.4 + 2.5 + 4.8 + 2.9 + 3.6 + 2.8 + 3.3 + 5.6 + 3.7 + 2.8 + 4.4 + 4.0 + 5.2 + 3.0 + 4.8)/15
Sample Mean = 56.8/15
Sample Mean = 3.8

Sample Size(n) = 15
So Median = (n+1)/2th term
Median = (15 + 1)/2th term
Median = 16/2th term
Median = 8th term
So the 8th term in the given data is 3.6. So,
Median = 3.6
(d) We have to compute the 20% trimmed mean for the above data set.
To compute the 20% termed mean, remove 20% of the largest and 20% of the smallest elements from the sample and compute the mean of the new sample.
New sample: 2.9 3.0 3.3 3.4 3.6 3.7 4.0 4.4 4.8
New Mean = 33.3/9
New Mean = 3.7
(e) We have to check is the sample mean for these data more or less descriptive as a center of location than the trimmed mean.
The mean value is 3.8, the median value is 3.6, and the trimmed mean value is 3.7. As a result, the sample mean is less descriptive as the location's center (median) than the trimmed mean.

the rocket coaster has 15 cars, some that hold 3 people and some that hold 5 people. there is room for 63 people altogether. how many 3-passenger cars are there? how many 5-passenger cars are there?
There are 6 cars that hold 3 people and 9 cars that hold 5 people.
How to determine the number of passengersLet's call the number of 3-passenger cars "x" and the number of 5-passenger cars "y".
We know the total number of cars is 15, so:
x + y = 15
We also know that the total number of passengers is 63, so:
3x + 5y = 63
Now we can use the first equation to solve for one of the variables in terms of the other:
y = 15 - x
Substitute this expression for y into the second equation:
3x + 5(15 - x) = 63
Expand
3x + 75 - 5x = 63
Evaluate like terms:
2x = 12
Divide both sides by 2:
x = 6
Recall that
y = 15 - x
So, we have
y = 15 - 9
y = 6

The equation of the line with a slope of -2/5 and passing through the point (5, -8) in standard, slope-intercept, form is; y = -0.4·x - 6
What is an equation?An equation consists of expressions and or numbers, expressed to be equivalent, by joining them with an '=' sign.
A standard form of the equation of a straight line is the slope-intercept form, which can be presented as follows; y = m·x + c
Where;
m = The slope of the graph of the equation
c = The y-intercept
The equation in the slope-intercept form can be obtained from the point-slope form, using the details of the slope of the graph of the equation (-2/5), and the point through which the graph of the equation passes (5, -8)
The point-slope of the equation is therefore;
y - (-8) = (-2/5)×(x - 5)
y + 8 = -2·x/5 + 2
y = -2·x/5 + 2 - 8 = -2·x/5 - 6 = -0.4·x - 6

find the inverse function of f(x) = 2x +3
Answer:
So the inverse function of f(x) = 2x + 3 is f⁻¹(x) = (x - 3) / 2.
Step-by-step explanation:
To find the inverse of a function, we switch the x and y variables and solve for y. So, we start with:
y = 2x + 3
Switching x and y, we get:
x = 2y + 3
Now, we solve for y:
x - 3 = 2y
y = (x - 3) / 2
So the inverse function of f(x) = 2x + 3 is f⁻¹(x) = (x - 3) / 2.
Answer & Step-by-step explanation:
To determine f's inverse function (x)= 2x + 3, we can follow these steps:
Step 1: Replace f(x) with y: y = 2x + 3
Step 2: Solve for x in terms of y:
y = 2x + 3
y - 3 = 2x
x = (y - 3) / 2
Step 3: Replace x with f^(-1)(x):
f^(-1)(x) = (x - 3) / 2
Therefore, the inverse function of f(x) = 2x + 3 is f^(-1)(x) = (x - 3) / 2.
