Step-by-step explanation:

Answer: slope and x-intercept

y-intercept and a point that is not an intercept is the information about the graph of the relationship is given. So, the correct answer is E. y-intercept and a point that is not an intercept

Let's analyze the information given in the problem:

1. The charity organization sold 18 tickets to cover necessary production costs.

2. They sold each ticket for $45.

3. They want to determine the net profit when they have sold 2 tickets.

We are given a specific point on the graph: (x = 2, y = net profit when 2 tickets are sold).

Now, let's calculate the net profit when 2 tickets are sold:

Net profit when 2 tickets are sold = Total revenue - Total production costs

Total revenue = 2 tickets * $45 per ticket = $90

Total production costs = $18 (to cover necessary production costs)

Net profit = $90 - $18 = $72

Now, let's look at the options:

A. Slope and x-intercept: We do not have the slope or the x-intercept of the graph.

B. Slope and y-intercept: We do not have the slope or the y-intercept of the graph.

C. Slope and a point that is not an intercept: We have a point on the graph, but we do not have the slope.

D. x-intercept and y-intercept: We do not have the x-intercept or the y-intercept of the graph.

E. y-intercept and a point that is not an intercept: We have the y-intercept (net profit when 0 tickets are sold, which is $18) and a point on the graph (net profit when 2 tickets are sold, which is $72).

F. Two points that are not intercepts: We have one point on the graph (net profit when 2 tickets are sold, which is $72), but we do not have another point.

So, Based on the information given, the correct option is:

E. y-intercept and a point that is not an intercept

Answer: 6 square root 2

Step-by-step explanation:

a) True. Some residuals will be positive and some will be negative. b) True. Least squares minimizes the squares of the residuals. c) False. y with a caret denotes predicted values.

a) True. Some of the residuals from a least squares linear model will be positive and some will be negative. Residuals measure the difference between the observed values and the predicted values, and they can be positive if the observed value is higher than the predicted value, or negative if the observed value is lower.

b) True. Least squares regression aims to minimize the sum of squared residuals. By minimizing the squares of the residuals, we ensure that the line of best fit is as close as possible to the data points.

c) False. We write y with a caret (^) to denote the predicted values and y without a caret to denote the observed values.

Answer:

With n = 50, both conditions(np > 5, n(1-p) > 5) are satisfied, so a random sample of 50 cars would have been large enough.

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to the normal distribution if:

np > 5, n(1-p) > 5

70% of the drivers traveling on a major interstate highway exceed the speed limit.

So p = 0.7.

Would a random sample of 50 cars have been large enough and why?

With n = 50

np = 50*0.7 = 35 > 5

n(1-p) = 50*0.3 = 15 > 5

With n = 50, both conditions(np > 5, n(1-p) > 5) are satisfied, so a random sample of 50 cars would have been large enough.

Answer:

A^B = A*A*A*... (B number of times)

The average rate of change can be calculated using the formula: (g(b) - g(a)) / (b - a), substituting -5 for a and 5 for b in our case.

In order to find the average rate of change of a function, in this case, function g, from x = -5 to x = 5, we use the formula: (g(b) - g(a)) / (b - a), where b is the ending value and a is the starting value. This gives us the slope of the tangent line that connects these two points on the graph, which reflects the average rate of change of the function over the interval. In this case, to find the average rate of change of function g from x = -5 to x = 5, we would substitute -5 for a and 5 for b in the formula to get: (g(5) - g(-5)) / (5 - (-5)). From here we can solve based on the known values of g(5) and g(-5).

Given:

Given that the radius of the circle is 12 inches.

The angle of the shaded sector is 210°

We need to determine the area of the shaded sector.

Area of the shaded sector:

The area of the shaded sector can be determined using the formula,

[tex]Area =(\frac{\theta}{360}) \pi r^2[/tex]

Substituting [tex]\theta=210[/tex] and r = 12, we get;

[tex]Area =(\frac{210}{360}) (3.142)(12)^2[/tex]

Simplifying, we get;

[tex]Area =(\frac{210}{360}) (3.142)(144)[/tex]

[tex]Area =263.9 \ in^2[/tex]

Thus, the area of the shaded sector is 263.9 square inches.

Hence, Option c is the correct answer.

Answer:

θ   [tex]0.75\pi[/tex]     [tex]1.75\pi[/tex]

r   10.551  244.151

Step-by-step explanation:

The maximum value for [tex]\theta[/tex] is:

[tex]\theta_{max} = \ln r[/tex]

[tex]\theta_{max} = 2.199\pi\,rad[/tex]

The formula for the slope of the tangent line in polar coordinates is:

[tex]m = \frac{r'\cdot \sin \theta + r \cdot \cos \theta}{r' \cdot \cos \theta - r \cdot \cos \theta}[/tex]

Horizontal tangent lines have a slope of zero. So, the following relation must be satisfied:

[tex]r'\cdot \sin \theta + r \cdot \cos \theta = 0[/tex]

[tex]r'\cdot \sin \theta = - r \cdot \cos \theta[/tex]

[tex]\tan \theta = - \frac{r}{r'}[/tex]

[tex]\tan \theta = -\frac{e^{\theta}}{e^{\theta}}[/tex]

[tex]\tan \theta = -1[/tex]

[tex]\theta = \tan^{-1}(-1)[/tex]

[tex]\theta = \frac{3}{4}\pi + i\cdot \pi[/tex], for all [tex]i \in \mathbb{N}_{O}[/tex].

The maximum value of i is:

[tex]i = \frac{\theta_{max}-\frac{3}{4}\pi }{\pi}[/tex]

[tex]i = \frac{2.199-0.75}{1}[/tex]

[tex]i = 1.449[/tex] ([tex]i_{max} = 1[/tex]).

Then, values are listed below:

r   10.551  244.151

Answer:

{ ( 2.193 , π / 4)   , ( 10.551 , 3π / 4) ,  ( 50.754 , 5π / 4)  , ( 244.151 , 7π / 4)  }

Step-by-step explanation:

Given:-

- The polar curve has the equation:

                           r = e^θ

- list the points starting with the smallest value of r such that:

                1 ≤ r ≤ 1000   ,  0 ≤ θ < 2π.

Find:-

List all of the points (r,θ) where the tangent line is horizontal

Solution:-

- We will first transform the polar curve to cartesian coordinate system using the parametric relations:

                  x = r*cos (θ)

                  y = r*sin (θ)

- The tangent line is horizontal when the " dy / dθ  " = 0 and " dx / dθ  " = 0, so:

                  x = e^θ*cos (θ)      ,    y = e^θ*sin (θ)

                  dx / dθ = e^θ*cos (θ) - e^θ*sin(θ)

                               = e^θ*[cos (θ) - sin(θ)]

                  dx / dθ = e^θ*[cos (θ) - sin(θ)] = 0,

                  e^θ = 0    ,      [cos (θ) - sin(θ)] = 0

                  e^θ ≠ 0 for the given interval 0 ≤ θ< 2π  

                  cos (θ) - sin(θ) = 0 , tan ( θ ) = 1 - (1st quad and 3rd quad)

                  θ = { π / 4 , 5π / 4 } , 0 ≤ θ< 2π    

- Similarly, evaluate dy/dθ = 0;

                   dy/dθ = e^θ*cos (θ) + e^θ*sin(θ)

                              = e^θ*[cos (θ) + sin(θ)]

                  dy / dθ = e^θ*[cos (θ) + sin(θ)] = 0,

                  e^θ = 0    ,      [cos (θ) + sin(θ)] = 0

                  e^θ ≠ 0 for the given interval 0 ≤ θ< 2π  

                  cos (θ) + sin(θ) = 0 , tan ( θ ) = -1 , (2nd quad and 4th quad)

                  θ = { 3π / 4 , 7π / 4 } , 0 ≤ θ< 2π

- All possibilities of " θ " over the interval satisfying the a horizontal tangent line to the given polar curve:

                  θ = { π / 4, 3π / 4 , 5π / 4 , 7π / 4 } , 0 ≤ θ < 2π  

- We will plug the evaluated list of values of "θ " in the given polar curve and determine the corresponding values of "r":

                  r = e^θ

                  θ = π / 4  , r = e^(π / 4) = 2.193        

               1: ( r , θ ) = ( 2.193 , π / 4)        

                  θ = 3π / 4  , r = e^(3π / 4) = 10.55072        

               2: ( r , θ ) = ( 10.551 , 3π / 4)  

                  θ = 5π / 4  , r = e^(5π / 4) = 50.754      

               3: ( r , θ ) = ( 50.754 , 5π / 4)  

                 θ = 7π / 4  , r = e^(7π / 4) = 244.151      

               4: ( r , θ ) = ( 244.151 , 7π / 4)          

Step-by-step explanation:

One year is 12 months.  12 mm is 1.2 cm.

Write and solve a proportion

1.2 cm / 4 months = x / 12 months

x = 3.6 cm

Given:

In ΔABC, ∠C = 90°, ∠A = 50° and AB = 3 unit.

To find the value of BC.

Formula:

By Trigonometric Ratio we get,

[tex]sin \ \theta=\frac{opposite}{Hypotenuse}[/tex]

Now,

With respect to θ = 50°, AB is the hypotenuse and AB is the opposite side.

So,

[tex]sin \ 50^{\circ}=\frac{BC}{AB}[/tex]

[tex]sin \ 50^{\circ}=\frac{BC}{3}[/tex]

     [tex]BC = 3 \times sin 50^{\circ}[/tex]

     [tex]BC = 2.298 = 2.3[/tex] (approx)

Hence,

The value of BC is 2.3 units.

Final answer:

The point estimate for the proportion of college students who prefer drink A is found by averaging the lower and upper bounds of the 95% confidence interval, which yields an estimate of 0.442 or 44.2%.

Explanation:

The point estimate for the true proportion of college students who prefer drink A is the midpoint of the 95% confidence interval. To find the point estimate, you sum the lower and upper bounds of the interval and divide by 2. In this case, the confidence interval is (.262, .622). The calculation for the point estimate is (0.262 + 0.622) / 2, which equals 0.442. Therefore, the point estimate is 0.442, which means that approximately 44.2% of college students prefer drink A.

Answer:

20%  

Step-by-step explanation:

Find the increase (subtract original number with final):

42-35= 7

Find the percent change (divide the increase by original number, then multiply by 100 to find the percentage):

[tex]\frac{7}{35}[/tex]*100=20

The percent change from 35 students to 42 students is 20%. This is calculated by using the formula for percent change: ((New Amount - Original Amount) / Original Amount) * 100.

In this case, we are trying to calculate the percent change in the number of students in Mrs. Mroc's class. The formula for percent change is:

((New Amount - Original Amount) / Original Amount) * 100

The New Amount is 42 (the number of students next year), and the Original Amount is 35 (the current number of students). So the percent change would be (((42-35)/35)*100), which equals 20%.

So, if Mrs. Mroc's class increases from 35 students to 42 students next year, the percent change will be 20%.

Stokes' theorem says the integral of the curl of [tex]\vec F[/tex] over a surface [tex]S[/tex] with boundary [tex]C[/tex] is equal to the integral of [tex]\vec F[/tex] along the boundary. In other words, the flux of the curl of the vector field is equal to the circulation of the field, such that

We have

Take the normal vector to [tex]S[/tex] to be
