Let's calculate how much she will spend:

She has to pay $200 for the rent.

She made 10 pendants that costed $7.80 each, that's a total of 10*$7.80 = $78.

Therefore, she will spend $200 + $78 = $278.

Let's define x as the amount of pendants she makes.  

To make a profit, the amount of pendants she makes, multiplied by $13.50 that is the price, has to be greater than $280 added to the amount of pendants she makes, multiplied by $7.80 that is the cost.

We write that as  

13.50x > 280 + 7.80x

Let's subtract 7.80x on both sides:

13.50x -7.80x > 280 + 7.80x - 7.80x

5.70x > 280

Now we divide by 5.70 on both sides:

5.70x/5.70 > 280/5.70

x > 49.1

To make profit, she needs to make and sell more than 49 pendants.

The combined present worth of the costs associated with the proposed bridge design, including construction and annual operating costs, is $10,583,333.

To calculate the combined present worth of costs, we need to consider the construction cost and the annual operating cost over the infinite life of the bridge. We will use the concept of present worth, which is the equivalent value of future costs in today's dollars.

The present worth of the construction cost is simply the initial cost itself, which is $9,000,000. This cost is already in present value terms.

For the annual operating cost, we need to calculate the present worth of perpetuity. A perpetuity is a series of equal payments that continue indefinitely. In this case, the annual operating cost of $700,000 represents an equal payment.

To calculate the present worth of the perpetuity, we can use the formula PW = A / MARR,

where PW is the present worth, A is the annual payment, and MARR is the minimum attractive rate of return (also known as the discount rate). Here, the MARR is given as 12%.

Plugging in the values, we have PW = $700,000 / 0.12 = $5,833,333.

Adding the present worth of the construction cost and the present worth of the perpetuity, we get $9,000,000 + $5,833,333 = $14,833,333.

However, since we are looking for the combined present worth, we need to subtract the salvage value, which is zero in this case. Therefore, the combined present worth of the costs associated with the proposed bridge design is $14,833,333 - $4,250,000 = $10,583,333, rounded to the nearest dollar.

(a) An approximate equation of the line of best fit can be obtained by visually estimating the slope and y-intercept of the line that best represents the relationship between the time spent studying (x) and the quiz score (y) based on the scatter plot.

(b) Using the equation from part (a), we can predict the quiz score for a student who spent 60 minutes studying by substituting x = 60 into the equation and solving for y.

Note: Without the scatter plot or additional data points, I am unable to provide specific values for the equation of the line or the predicted quiz score. However, I can guide you through the process of obtaining an approximate equation and making the prediction based on the given information.

To find an approximate equation of the line of best fit, visually inspect the scatter plot and identify the general trend or pattern of the data points. Look for the line that appears to best fit the overall distribution of points.

Once you have a general idea of the slope and y-intercept, you can write the equation of the line in the slope-intercept form: y = mx + b, where m represents the slope and b represents the y-intercept.

To predict the quiz score for a student who spent 60 minutes studying, substitute x = 60 into the equation obtained from part (a) and calculate the corresponding y-value.

Keep in mind that this is an approximation based on visual estimation and may not be as accurate as using statistical regression techniques. If precise values are required, it is recommended to perform a linear regression analysis using statistical software or tools to obtain a more accurate equation and prediction.

Slope is  $0.15 of the equation of cost  C=$0.15t+$35.00.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Given that A cell phone company uses the equation C=$0.15t+$35.00

C is the total cost for a month of service.

t is the number of text messages.

We have to find the slope of the equation.

slope is 0.15 and 35.00 is the y intercept of the equation given.

Hence, slope is  $0.15 of the equation of cost  C=$0.15t+$35.00.

The lighthouse keeper should land approximately 3 miles from the point on the shore nearest to the lighthouse in order to make the fastest possible time to the restaurant.

To determine the fastest possible time for the lighthouse keeper to reach the restaurant, we need to calculate the time it takes for him to row to the shore and then walk to the restaurant. The key is to minimize the total time taken.

Let's denote the distance from the landing point to the restaurant as x miles. The time taken to row to the shore can be calculated as 7 miles divided by the rowing speed of 2.7 mph, which is approximately 2.59 hours.

The time taken to walk from the landing point to the restaurant can be calculated as (14 + x) miles divided by the walking speed of 4 mph.

To minimize the total time, we need to find the value of x that minimizes the sum of the rowing time and the walking time. So, we can set up the equation:

Total time = 2.59 hours + (14 + x) miles / 4 mph

To find the value of x that minimizes the total time, we can take the derivative of the equation with respect to x, set it equal to zero, and solve for x.

However, given that we are asked to round the answer to the nearest whole number, we can simplify the problem by considering the value of x that yields the smallest whole number total time.

By trying different values of x, we can find the value that minimizes the total time.

When x = 0, the total time is 2.59 + 14 / 4 = 6.59 hours.

When x = 1, the total time is 2.59 + 15 / 4 = 6.84 hours.

When x = 2, the total time is 2.59 + 16 / 4 = 7.09 hours.

Continuing this process, we find that the smallest whole number total time occurs when x = 3.

Therefore, the lighthouse keeper should land approximately 3 miles from the point on the shore nearest to the lighthouse in order to make the fastest possible time to the restaurant.

Hence, three points. That can be plot on graph by using this linear equation are(0 ,0) (1 ,80) (2 , 160)

A linear equation is a two-variable equation that, when plotted on a graph, results in a straight line. Each term in the equation, which has a degree of 1, has an exponent of 1. Real-world events like the correlation between temperature and time of day are modelled using linear equations. Y = mx + b, for instance, is a linear equation where m is the line's slope and b is the y-intercept

We may use the slope-intercept form of a linear equation, which is y=mx+b where m is the slope and b is the y-intercept, to graph the equation Y=0.80x100.

In this instance, y=0.80x100 can be written as y=80x.

This line has an 80 percent slope, which means that for every increase in x of one, y rises by 80 percent.

We can select any three x values and then determine the matching y values to locate three locations on this line.

As an illustration,

if we select x=0, then y=80(0)=0

gives us the point. (0,0).

If we select x=1, then y=80(1)=80 and

the probability of getting (a, b), i.e. the first card is a and the second card is b is 2/3 by conditional probability.

The potential of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability. It is computed by dividing the likelihood of the earlier occurrence by the likelihood of the subsequent, or conditional, event.

This is where the independent event and dependent event notion is used. Consider a student who misses class twice each week, omitting Sunday. What are the possibilities that he will take a leave of absence on Saturday of the same week if it is known that he will be absent from school on Tuesday? It has been noted that situations where the outcome of one event influences the outcome of a subsequent event are termed as conditional probability
