The MAD for Doctor A's data set is 0.67 and the MAD for Doctor B's data set is 0.83. Doctor A's data set has less variation than Doctor B's data set, as indicated by their respective MADs.
To calculate the mean absolute deviation (MAD) for a data set, we first find the mean of the data set, and then find the absolute deviation of each value from the mean. We then find the mean of these absolute deviations.
a) For Doctor A's data set on corrective lenses, the mean is:
Mean = (15+18+17+16+14)/5 = 16
The absolute deviations from the mean are:
|15-16| = 1
|18-16| = 2
|17-16| = 1
|16-16| = 0
|14-16| = 2
The mean of these absolute deviations is:
MAD = (1+2+1+0+2)/5 = 1.2
Therefore, the MAD for Doctor A's data set is 1.2.
b) For Doctor B's data set on corrective lenses, the mean is:
Mean = (17+19+20+16+18)/5 = 18
The absolute deviations from the mean are:
|17-18| = 1
|19-18| = 1
|20-18| = 2
|16-18| = 2
|18-18| = 0
The mean of these absolute deviations is:
MAD = (1+1+2+2+0)/5 = 1.2
Therefore, the MAD for Doctor B's data set is also 1.2.
Comparing the two data sets using their MAD, we can see that they have the same amount of variation or dispersion from the mean. Both sets have a MAD of 1.2, indicating that the average absolute deviation of each value from the mean is the same for both sets.

The circle
The measure of angle at the center of the circle is calculated as
Center = 2 * 31
So, we have
Center = 62
The sum of angles in a triangle is 180
So, we have
x + x + 62 = 180
This gives
2x = 118
Divide by 2
x = 59
Hence, the value of x is 59

The probability that at least one number is odd and the sum of the two numbers is even is 1/4
The probability that exactly one number is 6 and the product of the two numbers is at most 15 is 1/9
The easiest way to figure out probability problems with small data sets is to write out your entire sample space and then divide by the total:
Sample size = 6 * 6 = 36

A rectangular parking lot has a perimeter of 112 and a area of 768 square meter what are the dimensions of the parking lot
Therefore, the dimensions of the parking lot can be 32 m × 24 m or 24 m × 32 m.
Let's represent the dimensions of the rectangular parking lot as 'l' and 'w.' Therefore, the perimeter of the parking lot can be expressed as:Perimeter, P = 2l + 2w
We are given the perimeter of the parking lot as 112.
Therefore,112 = 2l + 2w
Now, let's solve for l in terms of w
112 - 2w = 2l
56 - w = l
l = 56 - w
Now, let's represent the area of the parking lot as 'A'.A = lw 768 = l w 768 = (56 - w)w768 = 56w - w²0 = w² - 56w + 768 To solve the above quadratic equation, we will use the quadratic formula:
x = (-b ± √(b² - 4ac))/2a
On substituting the given values in the above formula, we get:
w = 24 or w = 32If w = 24, then l = 56 - 24 = 32If w = 32, then l = 56 - 32 = 24

a rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a wire fence. using 100 meters of fencing, what is the largest rectangular region that can be enclosed? give both the dimensions and the area.
Dimensions of the rectangular plot are 25' × 50'.
The area of a rectangular plot is 1250m.
What is the dimension of the rectangle?
Four perpendicular sides make up the two-dimensional geometric shape of a rectangle. Two of the four sides are distinct, and the other two resemble the distinctive sides. The dimensions of a rectangle are these two distinctive sides.
Here, we have
100 meters fencing
We have to find the dimensions and area of the rectangular plot.
so, 2x + y = 100
y = 100 - 2x
A = xy
A = x (100 - 2x)
A = 100x - 2x²
We differentiate w.r.t x, and we get
A' = 100 - 4x
We put, A'= 0
100 - 4x = 0
x = 25
y = 50
A = xy
A = 25 × 50
A = 1250m
Hence, the dimension of the rectangular plot is 25' × 50'.

The number of years it will take such that amount spent on each vehicle is the same will be 2.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Suppose after x years the amount will be the same.
5000 + 2500x = 8000 + 800x
2500x - 800x = 8000 - 5000

five cards are dealt from a standard 52-card deck. (a) what is the probability that we draw 2 aces and 3 kings? (round your answer to six decimal places.)
The probability of drawing 2 aces and 3 kings from a standard 52-card deck is 0.000002. To find the probability of drawing 2 aces and 3 kings, we need to first find the number of ways to choose 2 aces and 3 kings from the deck.
The total number of ways to choose 5 cards from a deck of 52 cards is given by the combination formula:
C(52, 5) = 52! / (5! * (52-5)!) = 2598960To find the probability of drawing 2 aces and 3 kings, we need to first find the number of ways to choose 2 aces and 3 kings from the deck. There are 4 aces and 4 kings in the deck, so the number of ways to choose 2 aces from 4 aces and 3 kings from 4 kings is given by:
C(4, 2) * C(4, 3) = 6 * 4 = 24Next, we need to find the number of ways to choose the remaining cards from the deck. There are 44 cards that are not aces or kings, so the number of ways to choose 5 cards from these 44 cards is given by:
C(44, 5) = 44! / (5! * (44-5)!) = 1,533,939Therefore, the total number of ways to draw 2 aces and 3 kings and 5 cards from the deck is:
24 * 1,533,939 = 36,854,536Finally, the probability of drawing 2 aces and 3 kings from a standard 52-card deck is:

The average amount of minutes exercised on each day
Step-by-step explanation:
We are given that every day "V" amount of vegetables are eaten everyday.
If there are 7 days in a week then the amount of vegetables eaten in 1 week would be 7V
E = ( M + W + F ) / 3
M = # of minutes exercised on Monday
W = # of minutes exercised on Wednesday
F = # of minutes exercised on Friday.
Note that to find the average of something you find the sum of the values and divide that by the number of values.
The equation "E" is adding up the # of minutes exercised on Monday, Wednesday and Friday and dividing the sum of that by 3, which happens to be the number of values being added( those values being the # of minutes exercised on Monday, Wednesday and Friday) . So we can conclude that the equation E represents an average, more specifically the average # of minutes exercised on each day.

A. Each output for y = 2x2 + 7 is 7 less than the corresponding output of y = 2x2. The graph of y = 2x2 + 7 is the graph of y = 2x2 translated down 7 units.
B. Each output for y = 2x2 + 7 is 7 greater than the corresponding output of y = 2x2. The graph of y = 2x2 + 7 is the graph of y = 2x2 translated up 7 units.
Option B is correct.
We have the two equations -
\(y= 2x^{2}\)
\(y=2x^{2} +7\)
We have determine how are these functions related and how are their graphs related.
What type of conic section is represented by equation -y = \($x^{2}\) ?A parabola is represented by the equation y = \($x^{2}\).
According to the question, we have -
\(y= f(x) = 2x^{2}\)
\(y=g(x)=2x^{2} +7\)
Refer to the image attached for graphs.
Now -
g(x) - f(x) = \(2x^{2} +7-2x^{2}\) = 7
Therefore - Each output for y = g(x) is greater than the corresponding output of y = f(x).
From the graph it is clear that the graph of y = g(x) is the graph of
y = f(x) translated up 7 units.

The probability of both rice and carrots being served with dinner is 23.4%.
The probability of Alvin's mother serving rice with dinner can be expressed using the formula P(Rice) = 0.78. This means that the probability of Alvin's mother serving rice with dinner is 78%. The probability of Alvin's mother serving carrots with dinner can be expressed using the formula P(Carrots) = 0.30. This means that the probability of Alvin's mother serving carrots with dinner is 30%. To calculate the combined probability of both rice and carrots being served with dinner, we can use the formula P(Rice and Carrots) = P(Rice) * P(Carrots) = 0.78 * 0.30 = 0.2340. This means that the probability of both rice and carrots being served with dinner is 23.4%.
