The reason why the events "choosing an odd number" and "choosing an even number" are mutually exclusive is; Choice D; a number is either even or odd.

<h3>What are Mutually exclusive events in probability?</h3>

It follows from probability theory, that two events are characterized as mutually exclusive if they cannot both occur at the same time. A very good example is the set of outcomes of a single die roll, which can result in any of the 6 outcomes.

The answer really depends on what b is. Unless you give me a number for what b equals I can’t solve it.

Find the margin of error for a 90% confidence interval when the standard deviation is LaTeX: \sigma= 50????=50 and LaTeX: n = 25
Murrr4er [49]

Answer:

The margin of error  for a 90% confidence interval is 16.4

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 25

Standard deviation = 50

z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64

Margin of error =

z_{critical}\times \dfrac{\sigma}{\sqrt{n}}

Putting the values, we get,

1.64\times \dfrac{50}{\sqrt{25}} = 16.4

Thus, the margin of error  for a 90% confidence interval is 16.4

What is the formula for the circumference of a circle?
Juli2301 [7.4K]

Answer:

C = pi * d = 2 * pi *r

Step-by-step explanation:

The circumference of a circle is the distance around the circle.  It can be found by multiplying the diameter times pi.

C = pi * d

We can replace the diameter with twice the radius

C = pi * 2 * r = 2 * pi *r
