With median, it is about the number that appears the most, and since the closest it gets is between $7,071 and $7,195, we have to pick the number that averages in-between which in this case is 7,185.

Below, this ↓ array proves the logic.

$\left[\begin{array}{ccc}7195&7185&7071\end{array}\right]$

Jeanine was making a baking. She used 1/2 cup of flour to make cookies and 2/3 cup of flour to make brownies. How much flour did

Fudgin [204]

Answer:

1 and 1/6 cups of flour

Step-by-step explanation:

We need the fractions to have common denominators so multiply 1/2 by 3 and 2/3 by 2 to get the common denominator of 6.

1/2 x 3/3 = 3/6

2/3 x 2/2 = 4/6

Add the two fractions

3/6 + 4/6 = 7/6 or 1 & 1/6

Show that each statement is true: Cos^4X-sin^4X=2cos^2X-1

Ivan

$cox^4x-sin^4x=2cos^2x-1\\\\
(cosx^2-sin^2x)(cosx^2x+sin^2x)=2cos^2x-1\\\\
cosx^2-sin^2x*1=2cos^2x-1\ \ \ | subtract\ 2cos^2x\\\\
-cosx^2-sin^2x=-1\ \ \ | multiply\ by\ -1\\\\
cosx^2+sin^2x=1\\\\
1=1$
