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.

a) The graph of the cost function for the Seattle factory starts with a flat line segment, then increases with a positive slope, and finally decreases with a negative slope.  b) The specific values for the slopes and endpoints depend on the exact calculations based on the given function, but this general description should provide an understanding of the cost structure over the specified domain.

a) To sketch a graph of the cost function for the Seattle factory, we'll use the given piecewise function and the specified domain [0, 42000].

First, we'll plot three points on the graph to represent the different parts of the function.

At 8000 units, the cost is 0.35.

At 20000 units, the cost is 0.75.

At 42000 units, the cost is 0.83 - (42000/200000).

Next, we'll connect the points with appropriate lines or curves based on the function's behavior over each part of the domain.

From 0 to 8000 units, the cost is constant at 0.35. This part of the graph will be a horizontal line segment at y = 0.35.

From 8000 to 20000 units, the cost increases. We'll draw an increasing line segment connecting the point (8000, 0.35) to the point (20000, 0.75). This represents a positive slope.

From 20000 to 42000 units, the cost decreases. We'll draw a decreasing line segment connecting the point (20000, 0.75) to the point (42000, 0.83 - (42000/200000)). This represents a negative slope.

b) Over each part of its domain, we can describe the function as follows:

From 0 to 8000 units, the cost is constant at 0.35. The function is constant with a slope of 0.

From 8000 to 20000 units, the cost increases. The function is increasing with a positive slope.

From 20000 to 42000 units, the cost decreases. The function is decreasing with a negative slope.

B. After 24 hours, approximately 2.49 grams will be left.

C. After approximately 18.13 hours, there will be approximately one gram left.

A. To represent the number of grams present after n hours, we can use the equation:

N(n) = 15 × (1 - 0.2)^n

Where:

N(n) is the number of grams present after n hours,

15 is the initial amount of the substance in grams,

0.2 represents the decay rate of 20% per hour, and

^n represents the exponentiation operation.

B. To find out how much will be left after 24 hours, we can substitute n = 24 into the equation from part A:

N(24) = 15 × (1 - 0.2)^24

Calculating this expression, we find that approximately 2.49 grams will be left after 24 hours.

C. We need to determine the number of hours it takes until there is approximately one gram left. We can set up the equation:

1 = 15 × (1 - 0.2)^n

To solve for n, we can divide both sides of the equation by 15 and then take the logarithm (base 0.8) of both sides:

log(0.8)(1/15) = n

Using a calculator or logarithmic properties, we find that approximately 18.13 hours are required until there is approximately one gram left.

Therefore, the answers are:

B. After 24 hours, approximately 2.49 grams will be left.

C. After approximately 18.13 hours, there will be approximately one gram left.

The resulting probability is 100%

How to calculate probability?

The general formula to calculate the probability is

=> P(B) = (n(B)/N(S)

where,

P(B) is the probability of an event 'B'.

n(B) is the number of favorable outcomes of an event 'B'.

n(S) is the total number of events occurring in a sample space.

Given,

A woman visits four different places: A, B, C, and D. If, at a given time, she is at point A, then the next hour she will be at point D with 100 percent probability. If she is at point B, then she will be at point A in an hour (with 100 percent probability) If she is at point C, then she will be at point A or B, with equal probabilities (that is, 50 percent each). If she is at point D, then she will be at point B or C with equal probability.

Here we have given that,

Number of places = 4 (A, B, C, D)

Initial point = A

Point D probability = 100%

For Point B to A probability = 100%

For point C to A or B probability = 50%

For point D to B and C probability = 50%

Now, here we need to find the probabilities that the woman will be at.

Like the women will spend three hours of travelling in the point A, B and C, then the probability of the points are calculated as,

=> 1 + 0.5 + 0.5 - 1

=> 2 - 1 = 1

Therefore, the resulting probability is 100%.

If Boll's son joins him in the work, they can pick a bale in 3 hours. Mr. Boll's son would take 7.5  or 7 1/2 hours to pick a bushel of apples by himself. So, the correct option is C.

Let's assume that the job of picking a bushel of apples by hand is represented by the variable x. Therefore, the rate at which Mr. Boll can pick apples is x/5 bushels per hour.

When Mr. Boll's son joins him, their combined rate of picking apples becomes x/3 bushels per hour. We can set up an equation to represent this relationship:

x/5 + x/t = x/3

where t is the time it takes Mr. Boll's son to do the job alone.

Multiplying both sides of the equation by the least common denominator (LCD) of 15t, we get:

3tx + 15x = 5tx

Simplifying, we get:

15x = 2tx

Dividing both sides by 15x, we get:

a) The proportion of cans in the shipment that meet the specification is (0.743, 0.871).

b) We cannot be 95% confident that the true proportion of cans in the shipment that meet the specification is equal to 0.80.

c) The true proportion of cans in the shipment that meet the specification is 385 cans.

d) The sample size must be an integer, we round up to the nearest whole number to get a sample size of 385 cans.

a) To calculate a 95% confidence interval for the proportion of cans in the shipment that meet the specification, we can use the following formula:

p +/- (1.96 × √(p * (1 - p))/n))

where p is the sample proportion of cans that meet the specification, n is the sample size, and 1.96 is the z-value for a 95% confidence interval.

Using the given values, the 95% confidence interval for the proportion of cans in the shipment that meet the specification is:

(52/70) +/- (1.96 × √(((52/70) × (1 - (52/70)))/70)) = (0.743, 0.871)

b) Based on the 95% confidence interval calculated in part a, we cannot agree with the claim made by the outside vendor that 80% of the aluminum cans meet specifications. The 95% confidence interval does not include the value of 0.80, and therefore we cannot be 95% confident that the true proportion of cans in the shipment that meet the specification is equal to 0.80.

c) To determine the sample size needed if the manufacturer wishes to be at least 95% confident that the error is within 0.05 of the true proportion of cans in the shipment that meet the specification, we can use the following formula:

n = (1.96² × p × (1 - p))/E²

where n is the sample size, p is the preliminary estimate of the proportion of cans that meet the specification, and E is the maximum error allowed.

Using the given values and a preliminary estimate of the proportion of cans that meet the specification of 0.80, the sample size needed is:

n = (1.96² × 0.80 × (1 - 0.80))/(0.05²) = 384.64

Since the sample size must be an integer, we round up to the nearest whole number to get a sample size of 385 cans.

d) To determine the sample size needed if the manufacturer does not have a preliminary estimate of the proportion of cans that meet the specification, we can use the following formula:

n = (1.96² × 0.5 × (1 - 0.5))/(E²)

where n is the sample size and E is the maximum error allowed.

Using the given value for the maximum error allowed, the sample size needed is:

n = (1.96² × 0.5 × (1 - 0.5))/(0.05²) = 384

Since the sample size must be an integer, we round up to the nearest whole number to get a sample size of 385 cans.

Answer: A and B are not independent, but mutually exclusive.

Step-by-step explanation:

Independence means that the probability of one event happening does not affect the probability of the other event happening. Mutual exclusivity means that the two events cannot happen at the same time.

In this case, we know that P(B|A) = 0.80, which means that the probability of Mark making a second goal given that he made the first goal is 0.80. This is different from P(B) = 0.55, the probability of Mark making a second goal without any information about whether he made the first goal. This means that the probability of event B is affected by whether event A has occurred, so A and B are not independent.

However, A and B are mutually exclusive, because Mark can either make his first goal or not, but can not make it at the same time.

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.
