Answer:
Correct choice is b.
Step-by-step explanation:
Rafael is taking a test that contains a section of 12 true-false questions. Exactly 8 correct answers of false from 12 true-false questions have
possible groups.
Start off by ordering the numbers from least to greatest:
8, 8, 8, 10, 14, 15
Now we can find that...
the mean (average) is 10.5
the median (middle) is 9
the mode is (most repeated number) is 8
and the range (difference of the largest and smallest number) is 7
Answer:
6(9+x)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Simplifying
m = 10x + -1x
<em>Combine like terms</em>: 10x + -1x = 9x
m = 9x
Solving
m = 9x
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Simplifying
m = 9x
Hope this helps :-D
Answer:
a) P=0.535
b) P=0.204
c) P=0.286
Step-by-step explanation:
The exponential distribution is expressed as
In this example, λ=1/8=0.125 min⁻¹.
a) The probability of having to wait more than 5 minutes
b) The probability of having to wait between 10 and 20 minutes
c) The exponential distribution is memory-less, so it is independent of past events.
If you have waited 5 minutes, the probability of waiting more than 15 minutes in total is the same as the probability of waiting 15-5=10 minutes.
