Consider the following data: 3,4,6,7,9,9,11

kodGreya [7K]

The data is already sorted for us. The median of this set is the middle most value which is 7 (in slot 4; three values to the left and three values to the right).

So the median is originally 7

If we add 5 to each data value we get
3+5 = 8
4+5 = 9
6+5 = 11
7+5 = 12
9+5 = 14
9+5 = 14
11+5 = 16

So the old data set
{3,4,6,7,9,9,11}
shifts to
{8,9,11,12,14,14,16}
after we add 5 to each value

The middle most value of the updated set is 12. It corresponds exactly to the old median of 7.

So we technically didn't even need to add 5 to all of the values to see what the new median would be. We simply need to add 5 to the old median to get the new median

I.e,
(new median) = (old median) + 5

A golf-course architect has sixsix linden trees, fourfour white birch trees, and threethree bald cypress trees to plant in a

zloy xaker [14]

Answer: There are 60060 ways to do so.

Step-by-step explanation:

Since we have given that

Number of linden trees = 6

Number of white birch trees = 4

Number of bald cypress trees = 3

Total number of trees = 6 +4 +3 =13

So, Number of ways that the landscaper plant that trees are evenly spaced is given by

$\dfrac{13\!}{6!\times 4!\times 3!}\\\\=60060$

Hence, there are 60060 ways to do so.

A company earns P dollars by selling x items, according to the equation P(x)=-0.002x^2+5.5x-1000. How many items does the compan

san4es73 [151]

So.. check the picture below

that's when the profit gets maximized

$\bf \qquad \textit{vertex of a parabola}\\ \quad \\

\begin{array}{lccclll}
P(x)=&-0.002x^2&+5.5x&-1000\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)$

how many items does the company need to sell? they need to sell $\bf -\cfrac{{{ b}}}{2{{ a}}}$
