We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.
Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.
Therefore, our variance is 225.
Answer:
7
Step-by-step explanation:
take the perimeter of what you have now (14) and divide it by 2, because it is dilated by 1/2
To make this a little clearer, let's give the pairs of inequalities the same denominator:
<span>Question 1:
</span>
?
First, apply the common denominator to the first fraction:
Do the same for the second:
Nest, compare the two fractions:
Therefore:
>
<span>
Question Two:</span>
?
Apply the common denominator to fraction one:
Fraction two:
Evaluate:
>
Therefore:
<span>
> </span>
Hope this helps!
Answer:
Mirandah added 5x and 9y, which she shouldn't do because one is y and the other is x, meaning they don't match.
There is no simplifying the equation. It should stay 5x + 9y - 4
If wrong, I apologize, but this should be correct.
