Mathematics
1 answer:
Harman [31]3 years ago
3 0

Answer:

19,600

Step-by-step explanation:

0-49=50 numbers

n=50

r=3

C(n,r)=n!/(r!(n-r)!)

=50!/(47!)(3!)

C(n,r)=C(50,3)

=50!/(3!(50−3)!)

= 19600

Write the slope-intercept from of the equation of the line through the given point with the given slope through (-1,4), slope =
g100num [7]
The point-slope form is y - y1 = m(x - x1) where x1 ad y1 are the coordinates given and the m is the slope, which is given also. Plugging these in, we have
y - 4 = -2(x - (-1)), which simplifies to y - 4 = -2(x + 1)

Find the equation of a line that contains the points (−2,2) and (−6,−5). Write the equation in slope-intercept form, using fract
mamaluj [8]

Answer:

y = (4/7)X + 22/7

Step-by-step explanation:

Moving from (-2, 2) to (-6, -5), we see that x (the "run") decreases by 4 and y (the "rise") decreases by 7 (from 2 to -5).  Thus, the slope is m = rise / run =

-4/(- 7) = 4/7.  The slope intercept form y = mx + b takes on the specific values 4/7 for m, 2 for y and -2 for x:

2 = 4/7(-2) + b, or 14 = -8 + 7b.  Thus, 22 = 7b, and b = 22/7.

The desired equation is y = (4/7)X + 22/7.
