ludmilkaskok [199]

Answer:

5

Step-by-step explanation:

To find the median number of

3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7

Number them from least to greatest

2 2 2 2 3 3 3 4 5 5 6 7 7 7 7 7 9 53

Since this isn't an even numbered set, all we do is cancel each number out equally on both sides until only one number which should be in the middle is left. This gives you an answer of 5

Hope this helps!

Write an algebraic expression to represent the verbal expression
MakcuM [25]
You set it up like this.

It says "the difference", so you put a minus sign: -
It says that the minuend, or the part being taken away from is a quantity equal to the product of 4 and "some number" (we'll use x), so now you have: (4 * x) -
Next, it says the subtrahend, or part being removed, is the square of "the number", meaning we use the "some number", x, from before, so now you have: (4 * x) - x^2
