please can i have a brainliest
So if they all add 4 hours to their time then they have:
Jeff 9
Mark 14
Karen 9
Costas 13
Brett 11
Nikki 9
Jack 11
so now to find the mean you add all the numbers together to get 76 and then you divide it by the number of people (7 people) so 76 divided by 7 equals 10.8571429 and that's the mean.
Now to find the median you put all the numbers in order from least to greatest: 9;9;9;11;11;13;14 and you take the number in the middle but since both 11 and 11 are in the middle you take the mean of them and the mean of them is 11 so the median of the numbers is 11
now to find the range you take the largest number (14) and you subtract the smallest number (9) so 14 - 9 is 5 so 5 is the range
and last the mode is the number that is repeated most out of all the numbers so the mode would be 9
Answer:
i think the answer is b give me brainliest please
Step-by-step explanation:
The expression shown below is a difference of two squares.
<h3>Is a given expression a perfect square trinomial or a difference of two squares?</h3>
In this problem we have an algebraic expression that has to be checked by algebraic procedures. The complete procedure is shown below:
(x² + 8 · x + 16) · (x² - 8 · x + 16) Given
(x + 4)² · (x - 4)² Perfect square trinomial
[(x + 4) · (x - 4)] · [(x + 4) · (x - 4)] Definition of power / Associative and commutative property
(x² - 16)² Difference of squares / Definition of power / Result
The expression shown below is a difference of two squares.
