Answer:
6
Step-by-step explanation:
(n- 1)(n)( n +1)=210
n(n²-1)=210
n³-n= 210
n³-n-210=0
let n = 6 => 6³-6-210 = 216-6-210 = 0 (true)
so, n = 6

Answer:
Ray, you need the slope-intercept formula y=mx+b
Step-by-step explanation:
Next you'll need 2 points, any points are fine. Just find two easy ones along the line. I'll just pick Point 1 as P1 = ( 0,4) and point 2 as P2 = (4,0) because they are easy to work with.
next use
point P1 (0,4) in the form (x1,y1)
point P2(4,0) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (0-4) / (4-0)
m = -4 / 4
m = -1
now use the point slope with one of the points, to find the slope-intercept form.
y - y1 = m(x -x1)
y - 4 = -1(x-0)
y -4 = -x
y = -x + 4
note:
y = mx +b
y = (-1)x + b is the form. see?
<span>Benford’s
law states that the probability that a number in a set has a given leading
digit, d, is
P(d) = log(d + 1) - log(d)</span>
The division property of logarithm should be use to make it
as a single logarithm
P(d) = log ( (d + 1)/ d)
So the probability that the number 1 is the leading digit
is
P(1) = log ( ( 1+1)/ 1)
P(1) = log ( 2)
<span>P(1) = 0.301</span>
