<h3>Answer: Commutative Property (choice C)</h3>
===================================================
Explanation:
Here are all of the justifications for each step
- Step 1. None needed. This is the original expression
- Step 2. Distributive property
- Step 3. Multiply (the 3 and 5 multiply to 15)
- Step 4. Commutative property. Specifically, this is the commutative property of addition which allows us to add any two numbers in any order we want. In this case, the -15 and 4x terms swap places.
- Step 5. Associative property. The parenthesis group the first two terms away from the third term.
- Step 6. Combine like terms. Both 3x and 4x have an x only so they are like terms that combine to 7x. You can think of it as 3+4 = 7, then you just tack an x onto everything to get 3x+4x = 7x.
Answer:
10
Step-by-step explanation:
(2/3) x (15)
is the same as
(2/3) x (15/1)
which means after you multiply them you get:
30/3
which simplifies to:
10
Answer:
Mean 
Median 
Mode 
Range 
Step-by-step explanation:
<u>The mean</u> is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. The total number is 862 cans, there are 30 numbers, then the mean is
<u>The median</u> is the value separating the higher half from the lower half of a data sample. There are 30 numbers in the sample, hence the median is the average value between 15th and 16th numbers:
<u>The mode</u> is the value that appears most often. Number 42 appears most often, so
<u>The range</u> is the difference between the maximum and minimum numbers in the sample, so
There was no error in the sentence.
<h3>What do you mean by
energy?</h3>
Energy, which is observable in the execution of labour as well as in the form of heat and light, is the quantitative quality that is transferred to a body or to a physical system in physics. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed. The joule (J) is the SI's (International System of Units) unit of measurement for energy. "The energy imparted to an object by the work of moving it a distance of one metre against a force of one newton" is how it is defined.
