The answer is variable, he’s correct.
Variables are letters used to substitute unknown values, as the question stated.
Answer:
y = 5
Step-by-step explanation:
I assume you want the equation of the line.
First we find its slope:-
m = slope = rise / run = 5-5/8-5 = 0 which means that the line is horizontal
and runs through the point where y = 5
Equation of this line is y =- 5.
Answer: <u><em>The weaknesses of content analysis include: if you make a coding error you must recode all of your data.</em></u>
Explanation:
Content analysis is a method for analyse documents,communication artifacts, which might be of various formats such as pictures, audio or video. Content analysis can provide valuable or cultural insights over time through analysis .
But it is more time consuming and subject to increased error . There is no theoretical base in order to create relationship between text. So in case if we make coding error then we must recode all data .
<u><em>Hence option (B) is correct</em></u>
54 = 3x + 37.5 <== ur equation....and x = number of years
54 - 37.5 = 3x
16.5 = 3x
16.5 / 3 = x
5.5 = x......so it would take 5.5 years...or 5 1/2 years <=
Hmmm to tell if they're orthogonal(perpendicular) to each other, we can simply get their dot-product, if their dot-product is 0, then they indeed are perpendicular, let's check
well, no luck there... now, let's introspect the digits a little
notice, the second vector, -28, 16, is just a multiple of the first one, that simply means, they're
parallel.
you can always just do a b/a check and simplify both vectors, if they yield the same ratio, they're parallel, since they're just multiples of each other.
