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).

Point of estimate of the true Proportion 'p' = 0.1941

Step-by-step explanation:

Explanation:-

Given data a random sample of 340 people in Chicago showed that 66 listened to WJKT-1450, a radio station in South Chicago Heights.

Given sample size 'n'= 340

Point of estimate of the true Proportion P  = [tex]\frac{x}{n}[/tex]

Properties of Estimation

An estimator is not expected to estimate the Population parameter without error.

An estimator should be close to the true value of un-known parameter.

Point of estimate of the true Proportion   = [tex]p = \frac{66}{340}= 0.1941[/tex]

Conclusion:-

Point of estimate of the true Proportion = 0.1941

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.

Answer:

[tex]BC=6\sqrt{2}\ units[/tex]

Step-by-step explanation:

In this problem i will assume that the side AB is the hypotenuse

The picture in the attached figure

we know that

In a right triangle, if one angle is 45 degrees, then the other angle complementary is equal to 45 degrees too

so

[tex]m\angle B=45^o[/tex]

In the right triangle ABC

[tex]cos(B)=\frac{BC}{AB}[/tex] ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

we have

[tex]cos(45^o)=\frac{\sqrt{2}}{2}[/tex]

[tex]AB=12\ units[/tex]

substitute

[tex]BC=cos(B)(AB)[/tex]

[tex]BC=\frac{\sqrt{2}}{2}(12)=6\sqrt{2}\ units[/tex]

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:

136=x

Step-by-step explanation:

When an angle is shown, the one opposite of it is equal to the forst equation. The bottom angles are equal to 360ñ so if you take 46x2=92. Subtract 92 by 360 to get 268. Divide it by 2 to get one of the bigger angles, which is 134 degrees. And as for the top, one angle on the bottom is equal to the same spot on the top. so, 136=x

Answer :

x = 134°

Step by step :

46° + x = 180°

x = 180° - 46°

x = 134°

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%.

Answer:

A. There is sufficient evidence to prove and conclude that the true average percentage differs from desired percentage.

B. P(Z<-4.93333) = 0.0000

C. n = 5945 samples

Step-by-step explanation:

A)

The rightnull and alternative hypotheses are given as below:

Null hypothesis H0: µ = 5.5

Alternative hypothesis Ha: µ ≠ 5.5

Conducting the one sample z test for population mean.

Test statistic formula is given as below:

Z = (Xbar - µ)/[σ/√(n)]

Given,

Xbar = 5.23

µ = 5.5

σ = 0.30

n = 16

Z = (5.23 – 5.5) / [ 0.30 /√(16)]

Z = -3.6000

P-value = 0.0003

α value = 0.05

P-value < α value

So, we reject the null hypothesis. There is sufficient evidence to prove and conclude that the true average percentage differs from desired percentage.

B

From the information given

Xbar = 5.23

µ = 5.6

σ = 0.30

n = 16

α value = 0.01

Z = (Xbar - µ)/[σ/√(n)]

Z = (5.23 - 5.6)/(0.30/√(16))

Z = -4.93333

P(Z<-4.93333) = 0.0000

Required probability = 0.0000

C

We are given α =0.01

Therefore, critical Z value = 2.57

E = 0.01

σ = 0.30

n = (Z*σ/E)^2

n = (2.57*0.30/0.01)^2 = 5944.41

n = 5945 samples

Complete Question:

For a healthy human, a body temperature follows a normal distribution with Mean of 98.2 degrees Fahrenheit and Standard Deviation of 0.26 degrees Fahrenheit. For an individual suffering with common cold, the average body temperature is 100.6 degrees Fahrenheit with Standard deviation of 0.54 degrees Fahrenheit. Simulate 10000 healthy and 10000 unhealthy individuals and answer questions 14 to 16.

14. If person A is healthy and person B has a cold, which of the events are the most likely? Pick the closest answer.  

a. Person B will have higher temperature than 101 degrees.

b. Person A will have temperature higher than 99 degrees

c. Person B will have temperature lower than 100 degrees

d. ​​Person A will have temperature lower than 97.5 degrees

15. What would be a range [A to B], which would contain 68% of healthy individuals? Pick the closest answer.  

a. Between 97.9 and 98.46

b. Between 99.5 and 101.6

c. Between 100.06 and 101.14

d. Between 100.1 and 102.2

16. What is the approximate probability that a randomly picked, unhealthy individual (one with the cold) would have body temperature above 101 degrees Fahrenheit? Pick the closest answer.  

a. About 10%

b. About 15%

c. About 22%

c. About 34%

Answer:

14. option a

15. option a

16. option a

explanation:

14 option (a)

person B have higher temperature than 101 degrees,  

(b) cannot be true if person a has higher temperature than 99 then he has cold most likely and as mentioned by the standard dev and mean of healthy people  

(c) AND (d) also cannot be true as they also do not satisfy the given standard dev and mean

15 option (a) because of the A to B range and not B to A range ....... as the healthy person's standard dev is 0.26. Hence the 68% data will lie in 97.94 - 98.46

but, if it was B to A, then the (c) option will be true

16 option (a) because most of the unhealthy individuals above the 0.54 standard dev will come somewhat near 90%

Answer:

The randomization will be centered around 0.5

Step-by-step explanation:

n = 30

Null hypothesis, H₀ : p = 0.5

Alternative hypothesis,  : p > 0.5

The randomization will be centered around 0.5

The indication of where the randomization distribution will be centered shows that the randomization distribution is always centered at the value of the parameter given in the null hypothesis, which is p = 0.5.

Thus, the randomization distribution is always centered at the value of the parameter given in the null hypothesis, which is p = 0.5.

The question is a math problem requiring a system of linear equations to solve. There were 70 grandparents, 140 parents, and 190 children at the family reunion. This was determined by assigning variables to each group and using the given conditions to form equations, which were then solved sequentially.

This problem can be solved using a system of linear equations. We can represent each group at the family reunion (children, parents, and grandparents) with a variable. To create equations from the information provided:

First, replace P and C in the total equation with the equivalent as per the other equations so it reads (2G + 50 + 2G + G = 400). Simplify this equation and you get 5G + 50 = 400. Solving for G, we find that there were 70 grandparents.

Plug the value of G (70) back in the equation for P (2*70), we find that there were 140 parents.

Similarly plug P (140) in the equation for C, we find that there were 190 children.

So, in conclusion, there were 70 grandparents, 140 parents, and 190 children at the family reunion.

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]

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)          

In the given data set, 12, 8, 6, 6, 9, 8, 7, 11, 6, the value 6 represents the mode.

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.
