8-5=3 : This means you add three each time
f(5)=8+3=1
f(6)=11+3=14
hope this helps :)
if not snap chat has a feature in the search bar and you can get answers by that
<span> t^2+4tv+4v^2
= (t + 2v)(t + 2v)
= (t + 2v)^2</span>
From the 64 values in the table on the left, count how many fall within the given ranges under the "classes" column in the table on the right. The "frequency" is the number of values in the data that belong to a given "class".
For example, "< -16.0" means "values below -16.0". Only one number satisfies this: -16.2 (first row, third column). So the frequency for this class is just 1.
Then for the range "-15.9 - 13.0", which probably means "numbers between 15.9 and -13.0, inclusive", the frequency is 0 because every number in the table is larger than the ones in this range.
And so on.
The probability is 34% because 9/26=.34615384615. The first 2 numbers makes the percentage
You only have the % and you need the number. For example i got a 87% on my Math test what is that as a decimal? The answer is 0.87 because you move the decimal ahead 2 numbers.
