Step-by-step explanation:
From Khan Academy, "Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are."

let n (AUB)=32n(B)=16and n(ANB)9 find n (A)
Answer:
32
Step-by-step explanation:
n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)
Given n(A)= ? we represent with x
n(B)= 16
n(A∪B) = 32
Substituting in equation 1 to get n(A)
32 = n(A) + 9 − 9
⇒n(A) = 32 − 0
n(A) = 32
to confirm this we put the values into the formula below
n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)
32 = 32 + 9 - 9
Answer:
n(A) = 25
Step-by-step explanation:
The relation between cardinality of two sets and that of their union and intersection is ...
n(A∪B) = n(A) +n(B) -n(A∩B)
32 = n(A) +16 -9 . . . . . use the given information
25 = n(A) . . . . . . . . . subtract 7

PLEASE HELP
We can write the two given inequalities as:
0 < x < 1/3
And the graph of it can be seen below.
How to graph the inequalities?
Here we want to graph the inequalities:
x < 1/3
x > 0.
To do it, we can rewrite the inequality as:
0 < x < 1/3.
To graph this, we need to work with a number line. First, we will mark both of the ends of the inequality, that is x = 0 and x = 1/3, both will be graphed with open circles, which means that these points are not solutions. Then, we need to shade the region between these points.

There are 150 people ina golf club.a) there are 50%more men than women in the golf club. How many mena nd how many women are ther in the golf club.
The percentage computed shows that the number of women is 60 while men are 90.
How to calculate percentage?Let the number of women be represented by x.
Since there are are 50% more men than women in the golf club, the number of men will be:
= x + (50% × c)
= x + 0.5x
= 1.5x
Therefore, 1.5x + x = 150
2.5x = 150
x = 150/2.5
x = 60
Number of women = 60
Number of men = 1.5x = 1.5 × 60 = 90

What is the second smallest prime number
Answer:
3
Step-by-step explanation:
3 is the second smallest prime number.
The second smallest prime number is 3
What are prime numbers:
⇒ numbers that are divisible only by itself and '1'
⇒thus they are numbers that have exactly two factors, itself and one
The first prime number is 2, not 1, because 1 doesn't have two factors. Thus, the second prime number is 3.

What is the median of this data set? {29, 22, 23, 31, 29, 29, 22, 23} Enter your answer in the box.
Answer:
The median is 26
Step-by-step explanation:
A "median" is equivalent to, when the terms are arranged in the proper order, whichever term is in the "middle".
So- first, arrange the terms in ascending order.
[22, 22, 23, 23, 29, 29, 29, 31]
There are an even number- eight- terms in total, so we will take the average of the two "middle" terms.
(29+23)/2; 29 and 23 are the "middle" terms, and there are two of them.
(52)/2 = 26
Therefore, the median is 26.

Answer:
application of L'Hopital's rule to the presumed indeterminate form yields this conclusion
Step-by-step explanation:
This is a reverse application of L'Hopital's rule for determining the limits involving indeterminate forms.
When the expression evaluated at the limit is 0/0, then L'Hopital's rule tells you the limit can be found from n'/d', where n and d are the numerator and denominator of the original expression, respectively.
We can see that x-π = 0 at x=π, so we assume that f(π) = 0 as well, and the expression n/d = f(x)/(x-π) evaluates to the indeterminate form 0/0.
The derivatives are ...
n' = f'(x)
d' = 1
Then we have the limit as ...
lim{x→π) = n'/d' = f'(π)/1 = 3 ⇒ f'(π) = 3
The conclusion f(π)=0 and f'(π)=3 follows from L'Hopital's Rule.

How much greater is the average rate of change over the interval [6,8] than the interval [5,7]?
============================================================
Explanation:
The average rate of change is the same as the slope of the line through the endpoints mentioned.
The interval [6, 8] means that we're talking about [tex]6 \le x \le 8[/tex]
When x = 6, we have y = f(x) = 1178When x = 8, we have y = f(x) = 2742So we're tasked to find the slope of the line through (6,1178) and (8,2742)
We'll use the aptly named slope formula.
[tex](x_1,y_1) = (6,1178) \text{ and } (x_2,y_2) = (8,2742)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{2742 - 1178}{8 - 6}\\\\m = \frac{1564}{2}\\\\m = 782\\\\[/tex]
The slope through those two endpoints is 782, which is the average rate of change on the interval [6, 8].
------------------
For the interval [5,7] we have [tex]5 \le x \le 7[/tex]
According to the function table,
When x = 5, y = 690When x = 7, y = 1852Like before, use the slope formula to find the slope through (5,690) and (7,1182)
[tex](x_1,y_1) = (5,690) \text{ and } (x_2,y_2) = (7,1182)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1182 - 690}{7 - 5}\\\\m = \frac{492}{2}\\\\m = 246\\\\[/tex]
This is the average rate of change on the interval [5,7].
------------------
The last step is to subtract the slopes:
782 - 246 = 536 which is the final answer
