Answer:

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|

Step-by-step explanation:

A solid metal cube of side 1-2 cm has a mass of 15 grams.

sashaice [31]

Answer:

The mass of the second cube is about 1085.07 grams.

Step-by-step explanation:

I assume '1-2 cm' means 1.2cm here. Correct me if I am wrong and I'll edit my answer.

First, find the density of this cube:

$d=\frac{m}{v}$

where d is density, m is mass, and v is volume.

We have one of those, but we also need volume. The volume of a cube is just:

$v=a^3$

where a is the length of a side.

$\rightarrow v=1.2^3\\\rightarrow v=1.728$

The volume of this cube is 1.728cm³. Now, you can find the density;

$\rightarrow d=\frac{15}{1.728}\\\rightarrow d\approx8.6806$

The density of this material is about 8.68 grams per cubic centimeter.

Finally, you can use that density to find the mass of the other cube. Fin the volume of the second cube:

$\rightarrow v=5^3\\\rightarrow v=125$

The volume is 125cm³. Given the density and the volume, you can calculate the mass:

$\rightarrow d=\frac{m}{v}\\\rightarrow 8.6806=\frac{m}{125}\\\rightarrow 8.6806\times125=m\\\rightarrow m=1085.0694$

The mass of the second cube is about 1085.07 grams.

At what price must I sell a motor car costing £2680 to make a gain of 5% on the cost? Please help

Papessa [141]

So 2680 divided by 100 is 26.80 which is 1%, times 26.80 by 5 to get 5% = £134, £2680+134= £2814

Solve for AB a: 3.6 b: 15 c: 4 d: 10

IrinaK [193]

A because 9 divided by 15 equals 0.6. Then I multiply 0.6 times 6 which equals 3.6. I didn’t 9 divided by 15 because they are congruent.

A student solved the given equation and justified every step except one. What is the missing reason? A) Associative property of

Anna007 [38]

Given:

The statements and reasons to solve an equation.

To find:

The missing reason.

Solution:

If a, b and c are three real number, then

Associative property of addition : $(a+b)+c=a+(b+c)$

Commutative property of addition : $a+b=b+a$

Multiplicative property of equality : $a=b\Leftrightarrow ca=cb$

Distributive property of multiplication over addition : $a(b+c)=ab+ac$

In the given step, $(x+-3)+3$ is written as $x+(-3+3)$ .

It means, only parenthesis are changed, which is possible by Associative property of addition.

So, the missing reason is Associative property of addition.

Therefore, the correct option is A.
