Answer:
y = -3x - 1
Step-by-step explanation:
The slope-intercept form is y = mx + b
m = the slope
b = y-intercept
Slope = rise/run or (y2 - y1) / (x2 - x1)
Point (-1, 2) (1, -4)
We see the y decrease by 6 and the x increase by 2, so the slope is
m = -6 / 2 = -3
Y-intercept is located at (0, - 1)
So, the equation is y = -3x - 1

The horizontal speed of a projectile is regular, and there's a vertical acceleration because of gravity; its cost is 9.8 m/s/s, down, The vertical speed of a projectile changes via nine.8 m/s every second, The horizontal motion of a projectile is impartial to its vertical movement.
we know that,
Projectile motion is a form of motion experienced with the aid of an object or particle that is projected in a gravitational field, such as from Earth's floor, and movements alongside a curved route below the action of gravity best.
Projectile motion is the movement of an object thrown (projected) into the air. After the initial force that launches the item, it most effectively reports the pressure of gravity. The object is known as a projectile, and its route is called its trajectory.
Calculation:-
vertical velocity = 70 cos 35° = 57.34 m/s.
height = 64 m tall
time = ?
S = ut +1/2 at²
75 = 57.34t + 1/2×9.8 t²
4.9t² + 57.34t - 75 = 0
t = 1.50035 Sec
V² = U² - 2aS
0 = U² - 2aS
U² = 2aS
S = U² /2a
= (57.34)²/2× 9.8
= 167.75
Total height = 75 + 167.75

John Austen is evaluating a business opportunity to sell premium car wax at vintage car shows. The wax is sold in 64-ounce tubs. John can buy the premium wax at a wholesale cost of $30 per tub. He plans to sell the premium wax for $80 per tub. He estimates fixed costs such as travel costs, booth rental cost, and lodging to be $900 per car show. Read the 1. Determine the number of tubs John must sell per show to break even. 2. Assume John wants to earn a profit of $1,100 per show. a. Determine the sales volume in units necessary to earn the desired profit. b. Determine the sales volume in dollars necessary to earn the desired profit. c. Using the contribution margin format, prepare an income statement (condensed version) to confirm your answers to parts a and b. 3. Determine the margin of safety between the sales volume at the breakeven point and the sales volume required to earn the desired profit. Determine the margin of safety in both sales dollars, units, and as a percentage.
1. To determine the number of tubs John must sell per show to break even, we need to consider the fixed costs and the contribution margin per tub. The contribution margin is the difference between the selling price and the variable cost per tub.
In this case, the variable cost is the wholesale cost of $30 per tub. The contribution margin per tub is $80 - $30 = $50. To calculate the break-even point, we divide the fixed costs by the contribution margin per tub:
Break-even point = Fixed costs / Contribution margin per tub
Break-even point = $900 / $50 = 18 tubs
Therefore, John must sell at least 18 tubs per show to break even.
2a. To earn a profit of $1,100 per show, we need to determine the sales volume in units necessary. The desired profit is considered an additional fixed cost in this case. We add the desired profit to the fixed costs and divide by the contribution margin per tub:
Sales volume for desired profit = (Fixed costs + Desired profit) / Contribution margin per tub
Sales volume for desired profit = ($900 + $1,100) / $50 = 40 tubs
Therefore, John needs to sell 40 tubs per show to earn a profit of $1,100.
2b. To determine the sales volume in dollars necessary to earn the desired profit, we multiply the sales volume in units (40 tubs) by the selling price per tub ($80):
Sales volume in dollars for desired profit = Sales volume for desired profit * Selling price per tub
Sales volume in dollars for desired profit = 40 tubs * $80 = $3,200
Therefore, John needs to achieve sales of $3,200 to earn a profit of $1,100 per show.
c. Income Statement (condensed version):
Sales Revene: 40 tubs * $80 = $3,200
Variable Costs: 40 tubs * $30 = $1,200
Contribution Margin: Sales Revenue - Variable Costs = $3,200 - $1,200 = $2,000
Fixed Costs: $900
Operating Income: Contribution Margin - Fixed Costs = $2,000 - $900 = $1,100
The condensed income statement confirms the answers from parts a and b, showing that the desired profit of $1,100 is achieved by selling 40 tubs and generating sales of $3,200.
3. The margin of safety represents the difference between the actual sales volume and the breakeven sales volume.
Margin of safety in sales dollars = Actual Sales - Breakeven Sales = $3,200 - ($50 * 18) = $2,300
Margin of safety in units = Actual Sales Volume - Breakeven Sales Volume = 40 tubs - 18 tubs = 22 tubs
Margin of safety as a percentage = (Margin of Safety in Sales Dollars / Actual Sales) * 100
Margin of safety as a percentage = ($2,300 / $3,200) * 100 ≈ 71.88%
Therefore, the margin of safety is $2,300 in sales dollars, 22 tubs in units, and approximately 71.88% as a percentage.

Using FUNCTION NOTATION, assume you are given the function: y = 3x - 2. This can be rewritten as
= 3x - 2, since y can be replaced with
The function notation will be:
f(x) = 3x - 2
Since y (the output) can be replaced with f(x).
How to use function notation?First, we know that a relationship between two variables x and y maps the first variable (called the input) into the second variable (called the output)
In this case, the relationship between x and y is linear, and is of the form:
y = 3x - 2
Particularly, if for each value of "x" that we use we get only one value of y as the output, then the relationship is called a function, and in that case we can write:
y = f(x).
So here to use function notation we just write:
f(x) = 3x - 2

Carlisle Transport had $4,520 cash at the beginning of the period. During the period, the firm collected $1,654 in receivables, paid $1,961 to supplier, had credit sales of $6,916, and incurred cash expenses of $500. What was the cash balance at the end of the period?
To calculate the cash balance at the end of the period, we need to consider the cash inflows and outflows.
Starting cash balance: $4,520
Cash inflows: $1,654 (receivables collected)
Cash outflows: $1,961 (payments to suppliers) + $500 (cash expenses)
Total cash inflows: $1,654
Total cash outflows: $1,961 + $500 = $2,461
To calculate the cash balance at the end of the period, we subtract the total cash outflows from the starting cash balance and add the total cash inflows:
Cash balance at the end of the period = Starting cash balance + Total cash inflows - Total cash outflows
Cash balance at the end of the period = $4,520 + $1,654 - $2,461
Cash balance at the end of the period = $4,520 - $807
Cash balance at the end of the period = $3,713
Therefore, the cash balance at the end of the period is $3,713.

\(m=\frac{y2-y1}{x2-x1}=\frac{100-60}{3-1}=\frac{40}{2}=20\)
So the slope is \(m=20\). Now we need to find y-intercept. We can do this by using our slope and a point in the point-slope equation, \(y=mx+b\). I'll use the point (1,60).

Estimate with a 95 percent confidence interval the difference in expected muscle mass for women whose ages differ by one year. Why is it not necessary to know the specific ages to make this estimate
Therefore, by using a representative sample and appropriate statistical methods, it is possible to estimate the difference in expected muscle mass for women whose ages differ by one year without knowing the specific ages of the individuals in the population.
It is not necessary to know the specific ages of women to estimate the difference in expected muscle mass for women whose ages differ by one year because the confidence interval is based on a population-level estimate rather than individual-specific data.
In this case, the confidence interval is constructed based on a sample of women, which provides an estimate of the average difference in expected muscle mass for women whose ages differ by one year in the population. The sample is selected randomly and is assumed to be representative of the population of interest.
By using statistical techniques, such as hypothesis testing and confidence interval estimation, we can make inferences about population parameters, such as the difference in muscle mass for women of different ages. These techniques rely on the assumption that the sample is representative of the population, rather than requiring specific individual-level information.

What
is the difference between Variance and Standard Deviation?
Give
examples of how they are applied.
Variance and standard deviation are both measures of the dispersion or spread of a dataset, but they differ in terms of the unit of measurement.
Variance is the average of the squared differences between each data point and the mean of the dataset. It measures how far each data point is from the mean, squared, and then averages these squared differences. Variance is expressed in squared units, making it difficult to interpret in the original unit of measurement. For example, if we are measuring the heights of individuals in centimeters, the variance would be expressed in square centimeters.
Standard deviation, on the other hand, is the square root of the variance. It is a more commonly used measure because it is expressed in the same unit as the original data. Standard deviation represents the average distance of each data point from the mean. It provides a more intuitive understanding of the spread of the dataset. For example, if the standard deviation of a dataset of heights is 5 cm, it means that most heights in the dataset are within 5 cm of the mean height.
To illustrate the application of these measures, consider a dataset of test scores for two students: Student A and Student B.
If Student A has test scores of 80, 85, 90, and 95, and Student B has test scores of 70, 80, 90, and 100, we can calculate the variance and standard deviation for each student's scores.
The variance for Student A's scores might be 62.5, and the standard deviation would be approximately 7.91. For Student B, the variance might be 125 and the standard deviation would be approximately 11.18.
These measures help us understand how much the scores deviate from the mean, and how spread out the scores are within each dataset.
