Answer:
495 ways
Step-by-step explanation:
We solve this above question busing the combination formula
C(n,r) = nCr
= n!/(n - r)! × r!
We are told in the question that:
A textbook search committee is considering 12 books for possible adoption the committee has decided to select 8 of the 12 for further consideration
C(12, 8)
n = 12
r = 8
12C8 = 12!/8! × (12 - 8)!
= 12!/8! × 4!
= 495 ways
Answer:
99.266
Step-by-step explanation:
11x6=66
7^2-6^2=13
sqrt13=3.6055
3.6055x6=21.633
21.633x2=43.266
43.266+66=99.266
Answer:
1. (AB) y = 2/3x + -4
Step-by-step explanation:
Formula - y = m(x) + (y-intercept)
m = rise / run
"run = horizontal (left and right)
rise = vertical (up and down)"
the y intercept is always going to be where y is 0 at. (x, y) you will use your x to determine the intercept
So lets use your first question as an example
1. (AB) y = m(x) + (y-int)
y = m(x) + (-4)
the point goes to the right 6 points and goes up 4 points (rise / run)
y = 4/6(x) + (-4)
You can round up the fraction to 2/3
y = 2/3(x) + -4
Answer:
Step-by-step explanation:
lengths of sides: 4x, 7x, 10x
perimeter = 4x+7x+10x = 84 cm
x = 4 cm
16 cm, 28 cm, 40 cm
