Answer:
a
Step-by-step explanation:
dsff
Step-by-step explanation:
A value is excluded when it makes the rational expression undefined. (such as making the denominator 0, etc.)
For example when x = 8, (x - 8) at the denominator will become 0 and make it undefined.
The correct options are the 3rd and 4th ones.

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
20/2-10/5. You divide 20 by 2 and subtract that from 10 divided by 5
