The line that is parallel to AC and passes through B has the equation y: 1/5x + 12/5.

The formula for a straight line is y=mx+c where c is the height at which the line intersects the y-axis, also known as the y-intercept, and m is the gradient.

The benefit of expressing a linear equation in this way is that the values for m and b correspond to the slope and y-intercept, respectively.

This makes it easy to graph the line that the equation describes.

So, the slope of AC is:

6-1/1/2= 5/-1 = -5

The equation of line D, which passes through B and is perpendicular to AC, is given as y: mx + p.

Where p is the y value of the y-intercept point and m is the slope.

The fact that line D is perpendicular to line AC indicates that their slopes add up to one.

Therefore,

(−5) × m = −1

Now,

m = -1/-5 = 1/5

We discover that the D equation is:

Y: 1/5x + p

To complete the equation of D at this time, we still require the value of p.

B(3, 3)∈ D

3 = 1/5(3) + p

p = 3 - 3/5 = 12/5 = 2.4

Hence, equation D will be:

y: 1/5x + 12/5

Therefore, the line that is parallel to AC and passes through B has the equation y: 1/5x + 12/5.

Finding the area of a triangle is straightforward if you know the length of the base and the height of the triangle. But is it possible to find the area of a triangle if you know only the coordinates of its vertices? In this task, you’ll find out. Consider ΔABC, whose vertices are A(2, 1), B(3, 3), and C(1, 6); let line segment AC represent the base of the triangle.

Part A

Answer: First, we can simplify 1/6 and 3/6 by finding a common denominator of 12:

1/6 = 2/12

3/6 = 6/12

Now we have:

2/12 + 6/12 + 1/12

Combining the numerators, we get:

9/12

Simplifying this fraction by dividing the numerator and denominator by their greatest common factor of 3, we get:

3/4

Therefore, the answer is C. 9/12.

Therefore, the approximate dimensions of the rectangle to the nearest tenth of a meter are width = 7.9 m and length = 10.8 m.

Area is a measure of the size of a two-dimensional surface or shape. It is typically expressed in square units, such as square meters (m²), square centimeters (cm²), square feet (ft²), or square inches (in²).

Here,

Let's denote the width of the rectangle as "w" in meters. Then, according to the problem statement, the length of the rectangle can be expressed in terms of the width as:

length = 2w - 5

The area of the rectangle is given as 97 square meters, so we can write:

area = length × width

Substituting the expression for length in terms of the width, we get:

area = (2w - 5) × w

Expanding this expression, we get a quadratic equation in standard form:

2w² - 5w - 97 = 0

We can solve this equation using the quadratic formula:

w = (-(-5) ± √((-5)² - 4×2×(-97))) / (2×2)

Simplifying this expression, we get:

w ≈ 7.9 or w ≈ -6.2

Since the width of a rectangle cannot be negative, we discard the negative solution and approximate the width to the nearest tenth of a meter:

w ≈ 7.9 m

Using the expression for the length in terms of the width, we can find the length:

length = 2w - 5

≈ 10.8 m

The correct order of the set of numbers from least to greatest is 2, 3 over 4, 2.71 repeating 71, 5 over 2, square root 5 option (D) is correct.

To order the given set of numbers from least to greatest, we need to compare their values. We start by noticing that 2 and 3 over 4 are equivalent to 2.75. Next, we compare the values of the remaining numbers. Since the square root of 5 is approximately 2.236 and 5 over 2 is equivalent to 2.5, we have:

2, 3 over 4 < 2.71 repeating 71 < 2.5 < square root 5

Therefore, the set of numbers in order from least to greatest is 2, 3 over 4, 2.71 repeating 71, 5 over 2, square root 5.

The data set as there are some large residuals, such as 4 and -7, indicating that the actual fares are not well-predicted by the linear equation.

In statistics, residuals refer to the differences between the observed values of a variable and the values predicted by a statistical model. They are calculated by subtracting the predicted values from the observed values.

To calculate the residuals, we first need to find the predicted fares for each distance using the equation y = 0.1 x + 12;

Miles        Fares $          Predicted Fares $              Residuals $

To find the residuals, we subtract the predicted fare from the actual fare. If the predicted fare is greater than the actual fare, the residual is negative, and if the predicted fare is less than the actual fare, the residual is positive. We can see that a linear model may not be appropriate for the data set as there are some large residuals, such as 4 and -7, indicating that the actual fares are not well-predicted by the linear equation.

c) Therefore, the probability that a customer will take a free sample and buy the product is 0.21.

d) The probability that between 60 and 80 customers will take the free sample and buy the product is approximately 0.043

a) Let X be the number of customers who take the free sample.

We know that X follows a binomial distribution with n = 327 and p = 0.58. To find the probability that more than 180 will take free sample, we need to find P(X > 180).

Using a binomial calculator or software, we get:

P(X > 180) = 1 - P(X ≤ 180) = 1 - binomial distribution (180, 327, 0.58, TRUE) ≈ 0.9999

Therefore, the probability that more than 180 customers will take your free sample is approximately 0.9999.

b) To find the probability that fewer than 200 will take your free sample, we need to find P(X < 200).

Using a binomial calculator or software, we get:.

P(X < 200) = binomial distribution (199, 327, 0.58, TRUE) ≈ 0.0119

Therefore, the probability that fewer than 200 customers will take your free sample is approximately 0.0119.

c) Let A be the event that a customer takes a free sample, and B be the event that the customer buys the product.

We are given P(B|A) = 0.35 and P(A) = 0.60.

Using the multiplication rule for dependent events, we get:

P(A ∩ B) = P(B|A) × P(A) = 0.35 × 0.60 = 0.21

Therefore, the probability that a customer will take a free sample and buy the product is 0.21.

d) Let Y be the number of customers who take the free sample and buy the product. We know that Y follows a binomial distribution with n = 327 and p = 0.21 (from part c). .

To find the probability that between 60 and 80 customers will take the free sample and buy the product, we need to find P(60 ≤ Y ≤ 80).

Using a binomial calculator or software, we get:

P(60 ≤ Y ≤ 80) = binomial distribution (80, 327, 0.21, TRUE) - binomial distribution (59, 327, 0.21, TRUE) ≈ 0.0434

The statement of Chang's is not correct.

Here given Chang's equation is x = 3y, which means that the length of the longest ski trail (x) is three times the length of the shortest ski trail (y).

Therefore, if we assume that the length of the shortest ski trail is y, then the length of the longest ski trail would be 3y.

So, in Chang's statement, he says that the longest ski trail is more than three times the length of the shortest ski trail. This would mean that x > 3y. However, according to Chang's equation, x = 3y, which contradicts his statement.

Therefore, Chang is incorrect in saying that the longest ski trail is more than three times the length of the shortest ski trail. In fact, the longest ski trail is exactly three times the length of the shortest ski trail, as per Chang's equation.

This is because the normal distribution provides a more precise approximation of the binomial distribution as the sample size increases.

However, if the the probability of success is very close to 0 or 1 or sample size is small then using the binomial tables to calculate the probability directly may be more accurate.

The cosine of angle X is 0.75 of triangle WXV.

In a right-angled triangle, the cosine of an angle is equal to the adjacent side divided by the hypotenuse. Therefore, to find cos(X) in triangle XWV, we need to find the adjacent and hypotenuse sides that correspond to angle X.

We know that WV = 72, which is the length of the side opposite the right angle. To find the length of the hypotenuse XV, we can use the Pythagorean theorem: [tex]XV^{2}[/tex] = [tex]WV^{2}[/tex] + [tex]WX^{2}[/tex], where WX is the length of the side adjacent to angle X.

Solving for WX, we get:

[tex]WX^{2}[/tex] = [tex]XV^{2}[/tex] - [tex]WV^{2}[/tex]

[tex]WX^{2}[/tex]= [tex]90^{2}[/tex] - [tex]72^{2}[/tex]

[tex]WX^{2}[/tex] = 2916

WX = 54

Now we can find cos(X):

cos(X) = adjacent/hypotenuse

The correct answer is: No, because for each input there is not exactly one output.

In mathematics, a function is a relation between two sets, where each element in the first set (called the domain) is associated with exactly one element in the second set (called the codomain or range). A function assigns a unique output value (dependent variable) to each input value (independent variable) from the domain.

The given relation does not represent a function because for some inputs there are multiple outputs, violating the "one-to-one" or "vertical line test" rule.

The correct answer is: No, because for each input there is not exactly one output.

In this relation, we can see that x = 1 has two different outputs, y = 5 and y = -1/2. Therefore, the relation does not meet the criteria of a function as it violates the requirement of having exactly one output for each input.

Answer:

yes these 2 triangles are similar

Step-by-step explanation:

triangle ABC is similar to triangle ADE. it has a scale factor of 1.5. It is a dilated. 10×1.5=15 so it has a scale factor of 1.5 which is an enlargement. any scale factor greater than 1 increases the size of the triangle. it is proportional if you multiply both sides by the scale factor (1.5) you get 15. also The angles are equal (AA similarity) these two triangles are NOT congruent but they are similar the degrees are equal. btw SSS and SAS are congruence postulates NOT similarity. so therefore they are similar because of AA

There are 2,139,792,767,488,000 ways to assign scores to the problems if the sum of the scores is 100 and each question is worth at least 5 points.

To solve this problem, we will use the concept of combinations with repetition.

First, let's subtract 5 points from each question, since each question is worth at least 5 points. Now, we need to distribute the remaining 50 points (100 - 10*5) among the 10 questions.

Imagine that we have 50 identical balls (points) to distribute among 10 distinct boxes (questions). To do this, we can use a technique called "stars and bars". We need to place 9 dividers (bars) between the 50 balls (stars) to divide them among the 10 questions.

We will have a total of 59 positions (50 stars + 9 bars). We need to choose 9 of these positions for the bars, and the stars will fill the remaining positions.

The number of ways to do this is given by the combination formula:

C(n, k) = n! / (k! * (n - k)!)

In our case, n = 59 (total positions) and k = 9 (dividers). So, we need to calculate C(59, 9):

C(59, 9) = 59! / (9! * (59 - 9)!)
C(59, 9) = 59! / (9! * 50!)
C(59, 9) = 2,139,792,767,488,000

Therefore, there are 2,139,792,767,488,000 ways to assign scores to the problems if the sum of the scores is 100 and each question is worth at least 5 points.
