Answers
Answer: Mean Absolute Deviation Calculator
Instructions
This calculator computes the mean absolute deviation from a data set:
You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".
What is the mean absolute deviation
The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.
Mean absolute deviation formula
This calculator uses the following formula for calculating the mean absolute deviation:
$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$
where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

how do you find the diagonal of a rectangle prism please step by step

Answer: How to find diagonal length of a rectangular prism?
Step-by-step explanation:To find the diagonal distance of a prism, you can use the formula: \displaystyle d = \sqrt{w^{2} + l^{2} + h^{2}}, where = height; = width, and = length. \displaystyle d = \sqrt{2^{2} + 8^{2} + 10^{2} } = \sqrt{4 + 64 + 100} = \sqrt{168} = \sqrt{4 * 42} = 2\sqrt{42}.
Please help I’m confused math is hard!
Answers
Answer:
Step-by-step explanation:
basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.
first, you need to factor out the equation.
start with the original equation.
V=4x^3+10x^2+4x
factored form:
V= 2x(2x^2+5x+2)
next, you're going to want to plug in the values.
the answer asks for x=4, but you should do both.
v=2(3)(2(3)^2+5(3)+2)
do not forget to do the exponents before!
v=6(18+15+2)
v=6(35)
v=210 ft^2
that's the answer for if x was equal to 3.
V= 2x(2x^2+5x+2)
don't forget to write the original equation first.
V=2(4)(2(4)^2+5(4)+2)
V=8(36+20+2)
V=464 ft^2⬆is your answer! hope this helped!!

I'm kidding...sorta.)
Whoever helps me out with this problem, thanks a lot!
Answers
Answer:I would presume 15
Step-by-step explanation:
I haven’t done any math yet but they should each have 1 head
Each parrot has 2 feet so 5*2 = 10. Each puppy has 4 feet so 4*10= 40. So 40+10= 50 feet and 10+5= 15 heads

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?
Answers
Answer:
$8,900
Step-by-step explanation:
You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.
Here i = $8,000*0.075*1.5 (representing 18 months)
i + $900
At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.
