40,43,40,39,50,23 what is the median?

Answers

Answer 1

Answer: Median is the middle number, but since there is 6 numbers.
Put them in order first
23,39,40,40,43,50
Well in middle is 40 for both sides
So to solve median for this you'd add the two middle numbers together since there is even set of numbers.
40+40 =80 then divide by 2
80÷2=40
Median = 40
*Follow This Example for any other even sets of numbers for Median*

Answer 2

Answer: The median of this data set is 40. This is because when put in order from greatest to least the order is:
23, 39, 40, 40, 43, 50
So the middle number is 40.

What two numbers add to negative 9 but multiply to 24

Answers

There aren't any numbers that add to 24 but multiply to 9. But you can still factorise - remember, you only need to get numbers that add up to the middle number if the coefficient of y^2 is 1. That means if you just have y^2, not 2y^2 or 3y^2 or 16y^2 like we do here.

16y^2+24y+9 = (4y+3)^2

The value of 7 is 200 percent of what number?

The polynomial 2x3 + 9x2 + 4x - 15 represents the volume in cubic feet of a rectangular holding tank at a fish hatchery. The depth of the tank is (x – 1) feet. The length is 13 feet.

Answers

Answer:

$(2x+5)(x+3)$

Step-by-step explanation:

The polynomial $2x^3 + 9x^2 + 4x - 15$ represents the volume in cubic feet of a rectangular holding tank at a fish hatchery

Use synthetic division to find the expressions representing the other sides of the tank

$(2x^3 + 9x^2 + 4x - 15)/(x-1)$

x-1=0 , add 1 on both sides

x=1, write all the coefficients and then divide by 1

In synthetic division, drop the first number

then multiply it with 1 and write it below the second number.

Add it and do the same

1 2 9 4 -15

0 2 11 15

-------------------------------------

2 11 15 0

Remainder is 0

Frame expression using the numbers 2 11 and 15

$2x^2+11x+15$

product is 2 times 15 = 30

sum is 11

6 times 5 is 30 , 6 plus 5 is 11

$(2x^2+6x)+(5x+15)$ , take out GCF from each group

$2x(x+3)+5(x+3)$

$(2x+5)(x+3)$
