Which two numbers multiplies to get -35 and adds to get - 3

1 answer:

3 0

A+b=-3, a=-3-b

ab=-35, and using a from above we get:

(-3-b)b=-35

-3b-b^2=-35

b^2+3b-35=0

b≈-7.6033 and 4.6033

So the two numbers are approximately -7.6033 and 4.6033

olya-2409 [2.1K]

8 = 4w/3

8 = 4w/3
×3 = 4w×3
24= 4w ( the two 3s cross each other out)
÷4 = ÷4
8 = w ( the two 4s cross each other out)

I was reading the comments from the other person who answered and I'm guessing both of you don't know what Mean Absolute Deviation (MAD) means.... I'm going to show you an example.......

For example:

2, 2, 4, 4

2 + 2 + 4 + 4 = 12 ÷ 4 = 3

12 ÷ 4 (because there are exactly 4 numbers)

Mean: 3

Mean Definition: The mean is the average of the numbers. To calculate it: add up all the numbers, then divide by how many numbers there are.

Mean Absolute Deviation (MAD):

2, 2, 4, 4 Mean: 3

(2 - 3) + (2 - 3) + (4 - 3) + (4 - 3) = 4 ÷ 4 = 1

Mean Absolute Deviation: 1

4 ( because I subtracted all the numbers and then added it all together) ÷ 4 (because there are exactly 4 number)

I hope your getting it because if you do it on paper it's easier.

Hope these helps!!!! Happy Holidays!!!! (:
