You have the correct answer. It is choice B) -1/4
=======================================================
Explanation:
This is because we're adding -1/4 to each term to get the next one. In other words, we're subtracting 1/4 from each term to get the next one.
- term2 = term1+(d) = 1/2 + (-1/4) = 1/2 - 1/4 = 2/4 - 1/4 = 1/4
- term3 = term2+(d) = 1/4 + (-1/4) = 1/4 - 1/4 = 0
- term4 = term3+(d) = 0 + (-1/4) = 0 - 1/4 = -1/4
- term5 = term4+(d) = -1/4 + (-1/4) = -2/4 = -1/2
and so on.
----------
To find the common difference, all we have to do is subtract any term from its previous one.
For example:
d = (term2) - (term1)
d = (1/4) - (1/2)
d = (1/4) - (2/4)
d = (1-2)/4
d = -1/4
The order of subtraction matters, so we cannot say d = term1-term2.
Answer:

Step-by-step explanation:
Given:
The table is given as:
x 0 4 7 8
y 0 24 42 48
The relationship between 'x' and 'y' is a proportional relationship.
A proportional relationship is one in which one variable varies directly with the other by a factor of 'k' also known as constant of proportionality and 
A proportional relationship is given as:

Now, we plug in 'x' and 'y' values and find the value of 'k'.
Let 

Therefore, the constant of proportionality is 6. Hence the complete equation is given as:

In order to determine which subset it belongs, we must rewrite

as



All these three numbers are irrational numbers, hence their product is also irrational

<span>So, they are looking for the percentage that is NOT explained...
Well, given the r we can find the percentage that IS explained by it first. That's given by r^2.
</span>Now - let's take the square of r it gives me .481636. That means that about 48% IS explained. Therefore, the part that cannot be explained
must be the missing part (out of 100% <span>so
100% - 48.1636% should be it :)
</span>
<span>So 100% - 48.1636% = 0.518364 and we want to round that off to three decimal places which will give us 0.518... and then we could convert that to a percent for the final. So 0.518 as a percentage is 51.8%! s</span>
