An employer must hire 2 people from a list of 13 applicants. In how many ways can the employer choose to hire the 2 people?

1 answer:

3 0

I’m guessing it’s simply 13/2 so it’s 6.5 different ways or if your supposed to round 7 different ways.
i might be wrong :)

Satya, nina, and iana each have a 3/4 chance of going to café georgia for an afternoon coffee at 1:00pm. Bohan will only go to c

larisa86 [58]

Using the binomial distribution, it is found that there is a 0.9844 = 98.44% probability that bohan goes to café georgia for a coffee today.

For each friend, there are only two possible outcomes, either they go to the cafe, or they do not. The probability of a friend going to the cafe is independent of any other friend, hence, the binomial distribution is used to solve this question.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

There are 3 friends, hence n = 3.

They all go to the cafe with a 3/4 probability, hence p = 3/4 = 0.75.

The probability at least one goes is:

$P(X \geq 1) = 1 - P(X = 0)$

In which:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{3,0}.(0.75)^{0}.(0.25)^{3} = 0.0156$

Then:

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0156 = 0.9844$

0.9844 = 98.44% probability that bohan goes to café georgia for a coffee today.

+23PTS! PDF Volume question -_- find diameter from the cylinder. I got 9 answer is 6 how???

Serga [27]

Answer: See below

Explanation:

For this question, we are given the volume, and we want to find the diameter. We have to work backwards to get our radius, then to find the diameter.

$V=\pi r^2h$ (Volume of cylinder)

$72\pi =\pi r^2h$ (The π cancel out)

$72 =r^2(8)$ (Plug in h=8)

$9=r^2$ (Divide 8)

$r=3$ (Square root of 9 is 3)

Now that we have our radius, we can find our diameter.

$d=2r$ (Equation for diameter)

$d=2(3)\\$ (Plug in r=3)

$d=6yards$ (Multiply)

A buffer is made with sodium acetate and acetic acid

tamaranim1 [39]

Answer:

Because Water is not a buffer solution and the acetic acid/acetate solution is a buffer solution. An acidic buffer is a solution of a weak acid (acetic acid) and its conjugate base pair (sodium acetate) that prevents the pH of a solution from changing drastically through the action of each component with incoming acid or base.
