Answer:
The mean is 7.2 and the median ( average) is 8
Step-by-step explanation:
4 + 10 + 8 + 9 + 5 = 36 / 5
The mean is 7.2 and the median ( average) is 8
1. (3x+1)(8x-2) 24x^2+8x-6x-2 24x^2+2x-2
2. (5n-5)(4n+8) 20n^2-20n+40n-40 20n^2+20n-40
3. (7x-2)(x^2-6x-5) 7x^3-2x^2-42x^2+12x-35x+10 7x^3-44x^2-23x+10
4. (5b-2)(3b^2-b+2) 15b^3-5b^2+10b-6b^2+2b-4 15b^3-11b^2+12b-4
I have the last two in a little bit.
Answer:
Yes
Step-by-step explanation:
We can add 20 to both sides and get 120=4v. Divide both sides by 4 and find that 30=v. Therefore, Lance is correct.
Using the Pythagoras theorem since it is given that it is a right angled triangle
let us name the triangle as A, B, C with B as right angle
AB^2 + BC^2 = AC^2 ( Pythagoras theorem)
where AB = 4 , BC = 7 , AC = x
