Based on the scatterplot of the transformed data and the residual plot, which type of model is appropriate for estimating print publication each year? A linear model is appropriate because the residual plot does not show a clear pattern. A power model is appropriate because the scatterplot of years and the log of circulation is roughly linear. An exponential model is appropriate because the scatterplot of years and the log of circulation is roughly linear and the residual plot shows no distinct pattern. Both an exponential and a power model would be appropriate because the log of circulation was used to develop the model.

For the data shown in the scatter plot, which is the best estimate of r? A. 0.95 B. −0.55 C. 0.55 D. −0.95

Answers

Answer:

C. 0.55

Step-by-step explanation:

The scatter plot shows that there is a positive correlation between variable x and variable y. This is because, the x and y variable seem to follow the same trend. That is, as x variable increases, y variable also increases. If a line of best fit is drawn, it would slope upwards, from left to our right.

Correlation coefficient (r) of any given data set plotted on a scatter plot, ranges from -1 to 1. The closer the value of "r" to either -1 or 1, the more clustered the data points are together in a line of best fit in a scatter plot.

Therefore, since the scatter plot given shows a positive relation between the x and y variables, whereby the data points seem to be less clustered and farther from each away from the line if best fit, if drawn, an estimate of "r" would not be closer to the value of 1.

Therefore, from the options given, C. 0.55 is the best estimate for r for the data shown in the scatter plot.

0.55

If an aircraft is present in a certain area, a radar correctly registers its presence with probability 0.99. if it is not present, the radar falsely registers an aircraft presence with probability 0.10. we assume that an aircraft is present with probability 0.05. what is the probability of false alarm (a false indication of aircraft presence), and the probability of missed detection (notng registers, even though an aircraft is present)? what is the probability that an aircraft is present given that the radar registers a presence?

Answers

Answer:

A) 0.005

B) 0.001

C)0.0495

Step-by-step explanation:

Let A be the event that an aircraft is present and let B be the event the radar registers its presence.. Thus;

P(A) = Probability that an aircraft is present

P(A') = Probability that an aircraft is not present

P(B) = Probability that the radar generates an alarm

P(B') = Probability that the radar doesn't generate an alarm

Thus from what we are given, we have;

P(A) = 0.05

P(A') = 0.95

P(B) = 0.99

P(B') = 0.01

P(B|A') = 0.1

A) Probability of a false alarm will be;

P(A' ∩ B) = P(A) × P(B|A')

P(A' ∩ B) = 0.05 × 0.1 = 0.005

B) probability of missed detection is;

0.1 × (1 - 0.99) = 0.001

C) probability that an aircraft is present given that the radar registers a presence will be;

P(A ∩ B) = P(A) × P(B)

P(A ∩ B) = 0.05 × 0.99

P(A ∩ B) = 0.0495

Answer:

The classification of the set of circumstances is presented in the following subsections of the understanding.

Step-by-step explanation:

A 7-year health research project revealed that individuals for whom the mom took DES throughout pregnancy seem to have been twice as probable as women for whom the mothers didn't use the medication to establish tissue irregularities that could cause cancer.  

(a)

Women with whom the mothers have taken DES throughout pregnancy as well as women where its mothers haven't taken DES during pregnancy.

(b)

The information collected seems to have been a sample or survey.  

(c)

A sampling unit of 3980 (women) showed that performance 63 industrialized tissue irregularities that could contribute to disease (cancer) in the proportion of females with whom the mom brought the powerful DES all through pregnancy.  

The proportion of abnormalities in tissues established by females does seem to be:

Answers

Answer:

Graph A: two distinct roots.  Graph B: one repeated real root. Graph C: two complex roots. Graph D: two distinct real roots.

Step-by-step explanation:

Explanation:

Each graph represents a quadratic function. So by the fundamental theorem of algebra, we know that each graph will have two roots.

Graph A crosses the x-axis twice. So, graph A has two distinct real roots.

Graph B touches the x-axis once. A quadratic cannot have one real root and one complex root. So it must have one repeated real root.

Graph C doesn’t cross the x-axis. This means it must have two complex roots.

Graph D crosses the x-axis twice. So, graph D has two distinct real roots.

Answers

Step-by-step explanation:

All u have to is subject t from that formula.

D=C( 1 + rt/100)

D/C = 1+ rt/100

D/C - 1 = rt/100

So,

When u multiply the equation by 100 and divide by r it will be as follows.

(D/C -1)100/r = t

It is the answer C.

And now to get the answer E,

we have the equation as t = (D/C-1) 100/r

First solve what inside the bracket.

D/C - 1

D/C - C/C

(D-C)/C

So when u put that to the above,

t= (D-C/C) 100/r

Now all u have to do is just multiply

t= 100(D-C) / Cr

Answers

Answer:

First off you have to start with what you know. You know the two planes cost 7.95 and you know the total is 24.65

Then to find the price of the stickers you subtract the 7.95 from  24.65=16.70

So your equation to start is

7.95+x=24.65

Subtract 7.95 from both sides

x=16.7-

c) 3
d) 6​

Answers

Answer:

A. 3

Step-by-step explanation:

Given,

[tex] BC = x + 15 [/tex],

[tex] AC = 14 [/tex]

[tex] AB = x + 7 [/tex], since A, B, and C are collinear, therefore, based on the segment addition postulate:

[tex] AB + BC = AC [/tex].

Thus, substituting the values into the equation, we have:

[tex] (x + 7) + (x + 15) = 14 [/tex]

Solve for x.

[tex] x + 7 + x + 15 = 14 [/tex]

[tex] 2x + 22 = 14 [/tex]

Subtract 22 from both sides

[tex] 2x = - 8 [/tex]

Divide both sides by 2

[tex] x = -4 [/tex]

[tex] AB = x + 7 [/tex]

Plug in the value of x

[tex] AB = -4 + 7 = 3 [/tex],

The Human user will think of a number between 1 and 100, inclusive. The program will make guesses and the user will tell the program to guess higher or lower. A sample run of the program might look like this: Ready to play (y/n)? y Think of a number between 1 and 100. My guess is 50. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 75. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 88. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: l My guess is 81. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: c Great! Do you want to play again (y/n)? y Think of a number between 1 and 100. My guess is 50. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: l My guess is 25. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 37. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: c Great! Do you want to play again (y/n)? n The strategy that the program will use goes like this: Every time the program makes a guess it should guess the midpoint of the remaining possible values. Consider the first example above, in which the user has chosen the number 81: On the first guess, the possible values are 1 to 100. The midpoint is 50. The user responds by saying "higher" On the second guess the possible values are 51 to 100. The midpoint is 75. The user responds by saying "higher" On the third guess the possible values are 76 to 100. The midpoint is 88. The user responds by saying "lower" On the fourth guess the possible values are 76 to 87. The midpoint is 81. The user responds "correct" Additional Requirements The purpose of the assignment is to practice writing functions. Although it would be possible to write the entire program in the main function, your solution should be heavily structured. Most of the point penalties given on this assignment will be for not following the instructions below carefully. The main function must look exactly like this. Copy and paste this code into your file, and don't edit it: int main() { char response; cout > response; while (response == 'y') { playOneGame(); cout > response; } } The playOneGame() function should implement a complete guessing game on the range of 1 to 100. The lower and upper bounds of the range should be assigned to global named constants and then not used again in your code. In addition, you should implement the following helper functions to be invoked inside your playOneGame() function: void getUserResponseToGuess(int guess, char& result) The getUserResponseToGuess() function should prompt the user to enter 'h', 'l', or 'c' (as shown in the sample output). It should set its "result" parameter equal to whatever the user enters in response. It should do this ONE time, and should not do anything else. Note that printing the guess is part of the prompt. int getMidpoint(int low, int high) The getMidpoint() function should accept two integers, and it should return the midpoint of the two integers. If there are two values in the middle of the range then you should consistently chose the smaller of the two. factorize the expression: 9x^4 + 12x^2y + 4y^2 The transition from nomadic life to village life might have included: Sending scouts to look for game Learning to like rice Exploring the Fertile Crescent Taming animals sequence of transformations Someone taking a course in Web design is affecting what factor of production?A. physical capitalB. entrepreneurshipC. human capitalD. land The point (1,-4) is on the line given by which equation below?A. y=-2xB. y=-4xC.
