Answer:
-8 to the power of 0 = 1
(Anything to the power of 0 = 1)
and 6 to the power of -1 = 1/6
( Any number to the power of a negative number will become a fraction)
Example.
So is will be 1/6 over 1
Which gives you your final answer.
Answer:
Basicly you just combine the terms that are the same. Combine -4x and -7x. Also combine 3 with -8.
Step-by-step explanation:
Answer: a. P (x<30) = 0.5276
b. P (30<x<35) = 0.0555
Step-by-step explanation: An <u>exponential</u> <u>distribution</u> is a distribution of time in which events happens at a constant average rate.
The rate is calculated as
with μ as the mean.
The probability density distribution for this type of distribution is
And probability is calculated as
For tuning of an engine, the rate is
λ = 0.025
a. Probability of less than 30 minutes:
P (X < 30) = 0.5276
<u>Probability of tuning in 30 minutes or less is </u><u>52.76%</u><u>.</u>
<u />
b. Probability of between 30 and 35 can be described as
P (X < 35) = 0.5831
P (X < 30) = 0.5276
Then:
P (30 < X < 35) = 0.0555
<u>Probability of tuning an engine between 30 and 35 minutes is </u><u>5.55%.</u>
