Measures of variation: ways to describe measures of central tendency for a data.

the most common measure of variation is range, so in this case, the smallest number is 1, and the largest is 17. This means the range is 16.

Interquartile Range:

Lower q: {1, 2, 4}
Upper q: {8, 12, 17}
Here you have to subtract 12 from 2, which gives you 10.

Mean absolute deviation:
Alright, let's first find the mean...

(1+2+4+5+8+12+17)
---------------------------= 7
7

What is the distance of each number from 7?

1: 6 units
2: 5 units
4: 3 units
5: 2 units
8: 1 unit
12: 5 units
17: 10 units

After adding all of these together, and dividing by 7, you will get...

4.571428 ≈ 4.6 or 5.

I hope these answers help you! Please give me brainliest!

Find the output, h, when the input, x, is -18

erastovalidia [21]

Answer:

The output H is 20 when the input, x, is -18

Step-by-step explanation:

H= 17 + x/6

When the input, x, is -18 then the output H will be:

H= 17 + 18/6

H= 17 + 3

H = 20

Answer: The output H is 20 when the input, x, is -18

If someone could help me out with this, I would greatly appreciate it!!

We are given that revenue of Tacos is given by the mathematical expression $-7x^{2}+32x+240$ .

(A) The constant term in this revenue function is 240 and it represents the revenue when price per Taco is $4. That is, 240 dollars is the revenue without making any incremental increase in the price.

(B) Let us factor the given revenue expression.

$-7x^{2}+32x+240=-7x^{2}+60x-28x+240\\-7x^{2}+32x+240=x(-7x+60)+4(-7x+60)\\-7x^{2}+32x+240=(-7x+60)(x+4)\\$

Therefore, correct option for part (B) is the third option.

(C) The factor (-7x+60) represents the number of Tacos sold per day after increasing the price x times. Factor (4+x) represents the new price after making x increments of 1 dollar.

(D) Writing the polynomial in factored form gives us the expression for new price as well as the expression for number of Tacos sold per day after making x increments of 1 dollar to the price.

(E) The table is attached.

Since revenue is maximum when price is 6 dollars. Therefore, optimal price is 6 dollars.
