[tex]3x \leqslant - 2 + 5 \\ 3x \leqslant 3 \\ \frac{3x}{3} \leqslant \frac{3}{3} \\ x \leqslant 1[/tex]
X CAN BE ALL THE NUMBERS LESS OR EQUAL TO 1
IN THE PICTURE THE ONLY OPTION THAT CONTRAST THE INEQUALITY IS OPTION B BECAUSE IT IS GREATER THAN 1.
HOPE THIS HELPS
Answer:
option B
Step-by-step explanation:
3x - 5 ≤ -2
add 5 to both sides
3x - 5 + 5 ≤ -2 + 5
3x ≤ 3
divided both sided by 3 to get x alone
3x/3 ≤ 3/3
x ≤ 1
option B is the only choice that is above 1.01 making it not a solution

Salaries of Business Graduates. Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $45,000 and $60,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. What is the planning value for the population standard deviation? How large a sample should be taken if the desired margin of error is a. $500? b. $200? c. $100? d. Would you recommend trying to obtain the $100 margin of error? Explain.
Answers
3750 is the planning value for the population standard deviation.
In the sampling, one should not recommend trying to obtain the $100 margin of error since the sample size is large.
Firstly, the planning value will be:
= (60000 - 45000) ÷ 4
= 3750
Then the number will be:
= 1.96 × (3750 ÷ 500)²
= 217
Also, for error 200, the desired margin will be:
= 1.96 × (3750 ÷ 100)²
= 5403.

The markup indicates the difference between the selling price and the item's cost to the business.In general, a corporation generates more money the higher the markup.The retail price of a product less its cost is known as markup, although the margin percentage is determined in a different way.
Calculate percentage on markup based on cost ?
The gross profit of a unit, which is its sales price less its cost to produce or acquire for resale, is divided by the unit's cost to determine the markup %.The markup percentage, which is computed as (12 - 8) / 8, is 50% for an item that costs the business $8 to produce but is priced at $12.Selling price = cost + markup
= 1.17+0.78
=1.96
percentage markup based on cost = markup/cost*100
0.78/1.17*100
= 66.66
percentage on selling = percentage on markup cost/100+percentage on cost
= 66.66/100%+66.66

To find PQ, notice that M divides PQ into two parts with the same measure.
So, we have:
[tex]10x+3=14x-13[/tex]Now, we can solve the above equation for x, and then find PQ.
To solve the equation, we can apply the same operations on both sides of the equation, until we isolate the variable x and find its value:
[tex]\begin{gathered} 10x+3-14x=14x-13-14x \\ \\ -4x+3=-13 \\ \\ -4x+3-3=-13-3 \\ \\ -4x=-16 \\ \\ \frac{-4x}{-4}=\frac{-16}{-4} \\ \\ x=4 \end{gathered}[/tex]So, using x = 4, we obtain:
[tex]\begin{gathered} PQ=2\cdot(10x+3) \\ \\ PQ=2\cdot(10\cdot4+3) \\ \\ PQ=2\cdot(40+3) \\ \\ PQ=2\cdot43 \\ \\ PQ=86 \end{gathered}[/tex]Therefore, PQ = 86.

What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
It is a relation of the form y = abˣ in mathematics, where x is the independent variable
From the expression, a is the coefficient, x is the exponent, and b is the variable
For the term, y = abˣ, compared with the general equations;
abˣ = 8x²
a = 8 and x = 2
This indicates that the term's coefficient is 8 and its exponent is 2.
Similarly for the second term -2x
So the coefficient of the term -2x is -2 and the exponent is 1
Hence, the coefficient of the term 8x² is 8 and the exponent is 2 and the coefficient of the term -2x is -2 and the exponent is 1.

What is the relationship between time and work?Time = 1 divided by the rate of work. If a task is completed across x days, then the amount of work completed in a single day is equal to 1/x. Total Work Done = Days * Productivity. Time and effectiveness are inversely related to one another.Time and work concerns concern the simultaneous performance of a person or a group's productivity and the amount of time it takes for them to finish a task. Work is the energy expended to complete a task or produce a deliverable.It takes a specific amount of time (T) to finish a particular task (W). The rate of work is the quantity of units of work completed per unit of time (R). Work (W) = Rate (R) Time, thus (T)sarah does the 1/5 of the job per hour.

1 These 5 main features are the title, scale, points, labels, and line.
2. Relations are a group of ordered pairs from one set of objects to another set of objects while functions are relations that connect one set of inputs to another set of outputs. So all functions are relations while all relations are not functions.
3. To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
4. The slope equation says that the slope of a line is found by determining the amount of rise of the line between any two points divided by the amount of run of the line between the same two points. In other words, Pick two points on the line and determine their coordinates.

Company C $40,000 during the first year. Assuming the cost and savings are equally
distributed across each month, after how many months will the company recover its
investment in Program X?
Answers
The business will need 10.5 months to make back the money it invested in Program X.
How do you determine monthly costs?Actual or anticipated costs for each monthly expense are needed to calculate the average monthly expenses.
How do you figure out the return on investment?By dividing an investment's net profit (or loss) by its initial cost or outlay, we can determine the return on investment.
Program X costs $35,000 per year, but is anticipated to save $40,000 for Company C in the first year.
Considering that the savings and the cost are equal over the course of each month
So, 40000/35000 = 0.875
No. of months to recover = 0.875 × 12
= 10.5 months
Therefore, the duration it will take the business to recover its
Investment in Program X is 10.5 months.
