The answer is 3.75.

Since the length of 'b' is one-half that of 7.5 based on the diagram (we know this because the partial radii connecting the two lines, or chords, are the same length, meaning the two chords are equal);

   <u>7.5</u>      ⇒   3.75<u>

Make b the subject of the formula P=2a+b
Gelneren [198K]
In order to make b the subject of this equation, we must isolate it on the left side. We can do this by following these steps:

P = 2a+b

Subtract b from both sides

P - b = 2a+b-b

P-b=2a

Subtract P from both sides

P-b-P=2a-P

-b=2a-P

Now, we have isolated b, but it is negative. We can fix this by multiplying both sides of the equation by -1.

-(-b)=-(2a-P)

b=-2a+P

Which is your final answer.
b = -2a+P.
Hope that helped! =)

If one wanted to find the probability of ten customer arrivals in an hour at a service station, one would generally use the ____
lbvjy [14]

If one wanted to find the probability of ten customer arrivals in an hour at a service station, one would generally use the Poisson probability distribution.

How do you find the probability of success for each trial?

  • Each trial has a head (success) and a tail (failure) outcome (failure). Each trial's chances of success are p = 1/2 and its chances of failure are q = 1 1/2 = 1/2.
  • The variable X, which counts the number of successes across 12 trials, is the one that interests us. This is an illustration of a 12-trial Bernoulli experiment.

What is the probability formula?

Probability is equal to the number of favorable outcomes (Total number of outcomes) P = n (E) / n (S) E is the event, P is the probability, and S is the sample area.
