Answer:
r=3
Step-by-step explanation:
if n=10
r=n-7
r=(10)-7
r=3
The comparison may be done by the dimensional analysis and the proper conversion factor. That is,
(7.8 x 10^5 m/h) x (1 km / 1000 m) x (24 h / 1 day) = 18720 km / day
The scientific notation of the answer is 1.872 x 10^4 km/day. Thus, the answer is letter D.
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
