Answer:

option B

4/11

Step-by-step explanation:

Given the word "probability" in the question

To find the probability of selecting letter 'b' or 'i' we will use following formula

probability = favourable outcome / total number of outcome

<h3>Total number of outcome = 11</h3><h3>favourable outcome = 4 </h3>

plug the values in the formula

The probability that a "b" or "i" is chosen = 4/11

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. Find the number.
Monica [59]

Equation to find number: \frac{1}{n} - 3 = \frac{20}{n}

Number's value: n = -\frac{19}{3}



Step-by-step explanation:

Let n be the unknown number.

The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be \frac{1}{n}.

The difference of three and the reciprocal of a number (\frac{1}{n}) would be \frac{1}{n} - 3.

The quotient of 20 and the number (n) would be \frac{20}{n}.

So, with this information we've gathered so far, we can come up with an equation to find what the number equals.

Equation: \frac{1}{n} - 3 = \frac{20}{n}

To find what the number equals we must solve the equation.

Your company has offices in 2 cities. The Denver office has 137 employees with an average salary of $67,013. The Anchorage offic
Charra [1.4K]

Alright, lets get started.

The Denver office has 137 employees with an average salary of $67,013.

So the total salay of all employees at Denver office will be = 137*67013

So the total salay of all employees at Denver office will be = $ 9180781

The Anchorage office has 25 employees with an average salary of $71,332.

So the total salary of employees at Anchorage office will be = 25 * 71332

So the total salary of employees at Anchorage office will be = $ 1783300

So, complete total salary of employees at both offices will be = 9180781+1783300

So, complete total salary of employees at both offices will be = $ 10964081

Total number of employees at both offices are = 137 + 25 = 162

So, the average salary of employee across the company = \frac{10964081}{162}

So, the average salary of employee across the company = 67679.5

Rounding off,

So, the average salary of employee across the company = $ 67680 : Answer

Hope it will help :)
