43% = 'Piano'
28% = 'Guitar'
15% = 'Harmonica'
12% = 'Drums'
2% = ...Other Instruments
- '2' Does seems as to be the <u>smallest</u> but it could be a trick.
- '43' Is the largest percentage out of the whole group.
- '100' Is what you get when you add all of the percentages together.
- And if you try to evaluate the percentages together in either way it'll end up to be '0.00004334' so that executes '250' and '150' from out of the question.
I'm not sure exactly what the actual answer could be but I'm assuming since it said "What is the smallest number of people required for the sample to meet the conditions for performing inference" Then my assumption is '2'.
Answer:
3.66
Step-by-step explanation:
35÷9.55=3.66
y = kx
'k' is the constant of proportionality, or otherwise known as constant of variation.
y = 90
x = 3
90 = k(3)
90 = 3k
3k/3 = 90/3
k = 30
The constant of proportionality is 30.
6^2/2(3)+4
Follow the order of operations, (GEMDAS) which goes like this:
<em>grouping, exponents, multiplication/divison, addition/subtraction
</em>
First up is our grouping, specifically parentheses. While we do have parentheses in our expression there isn't anything going on <em>inside</em> of them that we'd have to do first. (The 2(3) is another way of writing 2×3.)
Next we have exponents, which would be our 6^2. (6 squared)
When something is squared, that means it is multiplied by itself. 6^2 = 6×6 = 36.
Now our expression is 36/2(3)+4.
Next we need to handle the multiplication and division. (order doesn't matter)
The best way to do this is from left to right. The 36/2 = 18...
Then 18(3) = 54.
If we took 36(3) then divided by 2 we would get the same answer.
However, what you <em>cannot</em> do is multiply the 2(3), simply because the 2 is a denominator of a fraction. If you don't know what this is or why, it's okay--just always do it left to right and you'll never have to worry about it.
Now our expression is 54+4.
Finally, we can handle the addition/subtraction. 54+4 leaves us with 58.
