Answer:
(a)
Multiplicative inverse of w will be
(B) As w is same as the product of
So there multiplicative inverse will also be same
Step-by-step explanation:
We have given two complex numbers
and
(a) First we have to find
So
As we know that
So
Multiplicative inverse :
It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1
So multiplicative inverse of w will be
Because when we multiply with
it gives result as 1
(b) As w is same as the product of
So there multiplicative inverse will also be same
Answer:
The probability that all will last at least 30,000 miles is 0.3164.
Step-by-step explanation:
Consider the provided information.
For a particular tire brand, the probability of wearing out before 30,000 miles is 0.25. Someone who buys a set of four of these tires,
That means the probability of not wearing out is 1-0.25 = 0.75
Now use the binomial distribution formula.
Substitute p = 0.25, q=0.75, r=4 and n=4
The probability that all will last at least 30,000 miles is 0.3164.
