A deck of 52 hours has 4 nines.
P ( x ≥ 3 ) = ( 48 C 10 · 4 C 3 ) / ( 52 C 13 ) + ( 48 C 9 · 4 C 4 ) / ( 52 C 13 ) =
= 0.0412 + 0.588 = 0.1
Answer:
The probability is 0.1 ( or 10%).
For discontinuity of the function:
x² - 7 x - 8 ≠ 0
x² - 8 x + x - 8 = 0
x ( x - 8 ) + ( x - 8 ) ≠ 0
( x - 8 ) ( x + 1 ) ≠ 0
The points of discontinuity are: x = - 1 and x = 8.
As for the Domain of the function:
x ∈ ( - ∞, - 1 ) ∪ ( - 1 , 8 ) ∪ ( 8, +∞ ).
7) y = 4x
8) y = 7x/8
9) y = 25x/3
I think this are the answers.
Answer:
y = 6/5x - 2
Step-by-step explanation:
use y = mx+ c
m = slope
c = y intercept
y = 6/5x - 2
