(((3(4))+7)(7)) is the answer
Answer:
It's irrelevant.
Step-by-step explanation:
20 theater tickets cost 20T, 16 cinema tickets cost 16C.
Their sum is 20T+16C
You can factor a 4 out of this expression to get 4(5T+4C).
The two expressions are completely equivalent: there is no reason, in general, to prefer 20T+16C or 4(5T+4C).
Sometimes, the exercise may ask explicitly for the factored form.
In other cases, one of the two expression might be more useful: if you had to divide everything by 2, of course it's easier to write
If instead you had to subtract 10T, it would be more useful to write
To recap, 20T+16C and 4(5T+4C) are completely equivalent, and unless you have explicit requests, you may prefer one or the other depending on the calculations you have to do.
Answer:
14
Step-by-step explanation:
c = -4, x = 2
Lets plug in the numbers!
-3(-4) + 2
Order of operations states that multiplication will be done before addition.
Step 1. Multiply -3 by -4, and the product is 12.
-3(-4) = 12. New expression: 12 + 2
Step 2. Add 12 and 2, and the solution is 14
12 + 2 = 14. Solution to initial question: 14
Answer:
4% is a statistic and 1% is a parameter
Step-by-step explanation:
First, let's remember the differences between parameters and statistics:
Parameters are values that describe data of the entire population.
Statistics are values that describe data from a sample.
The value of 1% refers to "all of the parts", which is the population of over 1 million parts, thus 1% is a parameter.
The value of 4% refers to the "100 selected", which is the sample of 100 parts, thus 4% is a statistic.
Therefore, 4% is a statistic and 1% is a parameter.
