The answer is C:
Starting with the given formula for the area, A = 1/2hb, the first step is to isolate h by using the multiplicative inverse of b, which is on both sides of the equation:
The result will be:
The last step is to use the multiplicative inverse of , which is 2 or
to further isolate the variable <em>h </em>:
The formula for h will be:
which is the option C in your question.
Answer: 0.01145
Step-by-step explanation:
We use Binomial distribution , where the probability of getting x successes in n trial is given by :-
, p = probability of getting each success in each trial.
As per given
The proportion that a car with a certain protection system will be recovered= p=0.87
n= 8
Let x be the number of cars will be recovered.
Then, the probability that 4 of 8 stolen cars will be recovered:
Hence, the required probability is 0.01145.
