What is the Mean Absolute Value?​

Answers

Answer:

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.

Step-by-step explanation:

The average absolute deviation, or mean absolute deviation, of a data set is the average of the absolute deviations from a central point. It is a summary statistic of statistical dispersion or variability.

Simplify each of the following equationS and solve for x
7 - 3x = -x + 1

Answers

Answer:

[tex]x=3[/tex]

Step-by-step explanation:

The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:

[tex]7 = 2x + 1[/tex]

Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:

[tex]6 = 2x[/tex]

The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:

[tex]3 = x[/tex]

f(5) = -11

Step-by-step explanation:

Given that,

We need to find the value of f(5).

Put x = 5 in equation (1)

f(5) = 4-3(5)

= 4-15

= -11

So, the value of f(5) is equal to -11.

of these 400 eels, 10 are ringed
Work out an estimate for the total number
of eels in the lake.

Answers

Answer:

2000 eels

Step-by-step explanation:

Let us represent the total estimate of the eels = x

She returns the 50 eels to the lake.

The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.

To solve the above question, we have the following:

50/x = 10/400

Cross Multiply

10x = 50 × 400

x = 50 × 400/10

x = 2000 eels

Therefore, the total estimate of the eels in the lake = 2000 eels

1. 22.9 ft pick and awnser!! :)

2. 28.5 ft

3. 33 ft

4. 30 ft

Answers

Answer:

33feet

Step-by-step explanation:

If the base of the doghouse is 6 feet and the height is 5 feet, we can write;

6 feet base = 5 feet height

To get the length of the base if the height is 27.5feet

x feet base = 27.5 feet high

Divide both expressions

6/x = 5/27.5

5x = 6 * 27.5

5x = 165

x = 165/5

x = 33ft

Hence the length of its base will be 33feet

(50 POINTS HELP)The manager of a restaurant chain wants to know how many times per month diners come to his restaurant. The table shows the number of visits in one month for three samples of 10 randomly chosen diners.

3. Based on the data, would you predict that, in one month, the average diner would visit the restaurant fewer than 3 times, 3 or 4 times, or, about 4 times? Explain your reasoning.

Write your answer in the space below.

Answers

Answer:

Means

sample 1: 3.6

sample 2: 3.3

sample 3: 3.8

Step-by-step explanation:

Three or four times. All of these means are no less than three but no more than four this means that the average number of times is between three or four

a) The mean of the sample 1 = 3.6

b) The mean of the sample 2 = 3.3

c) The mean of the sample 3 = 3.8

d) In one month, the average diner would visit the restaurant 3 or 4 times

What is Mean?

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the mean of the sample 1 be represented as M₁

Let the mean of the sample 2 be represented as M₂

Let the mean of the sample 3 be represented as M₃

where the number of visits to restaurant in one month is given by

Sample 1 = { 5 , 2 , 6 , 4 , 4 , 7 , 2 , 1 , 2 , 3 }

The number of visits = 10 visits

The total sum of sample 1 = 36

So , mean M₁ = 36/10 = 3.6

And , Sample 2 = { 2 , 6 , 1 , 3 , 4 , 5 , 2 , 1 , 5 , 4 }

The number of visits = 10 visits

The total sum of sample 1 = 33

So , mean M₂ = 33/10 = 3.3

And , Sample 3 = { 3 , 3 , 6 , 4 , 1 , 5 , 3 , 4 , 4 , 5 }

The number of visits = 10 visits

The total sum of sample 1 = 38

So , mean M₃ = 38/10 = 3.8

And , the average diner would visit the restaurant 3 or 4 times because the mean value of the three samples lies between 3 and 4

Hence , the mean of the sample is solved
