The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0.
Tacking on "-8" to |x+5| leads to |x+5|-8
The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|
Final Answer: choice C)
Answer:
a) P [ x ≤ 7000] is 0.55
b) P [ x > 5000 ] = 0.95
c) P [ 5000 < x ≤ 7000 ] = 0,5
Step-by-step explanation:
a) P [ x > 7000 ] = 0.45 straightforward P [ x ≤ 7000] is 0.55
The whole spectrum of probabilities is 1 which in this particular case is divided in two parts having 7000 as a limit, then we subtact 1 - 0.45
b) P [ x ≤ 5000] = 0.05 again we get P [ x > 5000] taking 1-0.05 to get
P [ x > 5000 ] = 0.95
c) P [ 5000 < x ≤ 7000 ]
Under Normal curve distribution the probability of x ≤ 7000 includes values smallers ( to the left of 5000) so we subtract from 0.55 - 0.05 = 0.50
c) P [ 5000 < x ≤ 7000 ] = 0,5
The answer is c for if you count the spaces in the half of brad, you get 4 and in half of kely, you get 8 which is a 2:1 ratio with kely and brad because kely's bigger
No, because it is likely that team A will win.
Answer:
59049/1048576
Step-by-step explanation:
So, with -3/4^5, we have
-3/4*-3/4*-3/4*-3/4*-3/4
This simplifies to,
-243/1024.
This squared, then gives us
(-243/1024)*(-243/1024)
This gives us
59049/1048576.
