Answer:

Step-by-step explanation:

Step 1: Calculate the mean.

Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.

Step 3: Add those deviations together.

Step 4: Divide the sum by the number of data points.

Answer:

Sample Answer: First, find the mean of the data set by averaging. Next, find the absolute deviations for each data point. That is, find the distance each point is from the mean. Then find the mean of the absolute deviations.

Which did you include in your explanation? Check all that apply.

Find the mean of the set of data.

Find the absolute deviations for each point.

Absolute deviation is a data point’s distance from the data set’s mean.

Guys help me with a) and b) tasks<br>ANSWER:<br>a) 40<br>b) 25<br>Thanks<3

Step-by-step explanation:

there are 2 similar triangles : ABE and DCE

that means they have the same angles, and the scaling factor from one triangle to the other is the same for every side.

and that means that

DE/AE = EC/BE (= DC/AB)

we know that

AE = AD + DE

BE = BC + EC

so, we have actually

DE/(AD+DE) = EC/(BC+EC)

DE/(10+DE) = 8/(2+8) = 8/10 = 4/5

DE = 4(10+DE)/5

5DE = 4(10+DE) = 40 + 4DE

DE = 40 cm

AD/DE = 3/5

BC/EC must be 3/5 too.

15/EC = 3/5

15 = 3EC/5

75 = 3EC

EC = 25 cm

4 What is the solution to the inequality -3x-42>3 ?

Vladimir [108]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

What is the solution to the inequality -3x-42>3 ?

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$- 3 x - 42 \gt 3$

Add 42 to both sides.

$-3x>3+42$

Add 3 and 42 to get 45.

$-3x>45$

Divide both sides by -3. As -3 is <0, the inequality direction has changed.

$x$

Divide 45 by -3 to get -15.
