Answer:
8√2
Step-by-step explanation:
4√(10) -2
= 4√8
=4√4×2
=4×2√2
=8√2
supplementary angles sum up to 180°, so let's say we have two angles, a and b, a + b = 180, but we know that a is <u>twice the measure of her partner</u>, so a = 2b.

Answer:
There isn't one
Step-by-step explanation:
√q differs from √(q+1) by 1 only when q=0. The difference gets smaller as q gets larger.
___
Here, q=7x. The same logic applies.
Answer:
1.8 x 10^3
Step-by-step explanation:
(8.1 x 10^8) / (4.5 x 10^5) = 1800
1800 = 1.8 x 10^3
Answer:
<h2>The Mean Absolute Vale (MAD) is 4.4</h2>
Step-by-step explanation:
The mean absolute deviation is defined as

Where
is the mean and
is the total number of data.
The means is defined as

And, 
Replacing these values, in the MAD formula, we have

Therefore, the Mean Absolute Vale (MAD) is 4.4
