Answer:

$3,000

Step-by-step explanation:

There two possible outcomes:

There is a 3/4 chance that the bid is rejected for a value of -$1,400

There is a 1/4 chance that the bid is accepted for a value of $17,600 - $1,400.

The expected value of the situation is:

E = \frac{3}{4}*(-1,400)+\frac{1}{4}*(17,600-1,400)\\E=\$3,000

The expected value is $3,000.

What are real numbers? How are real numbers used to solve problems?
Tom [10]

Answer:

The real numbers include all the rational numbers, such as the integer −5 and the fraction 4/3, and all the irrational numbers, such as √2

Real numbers are used in measurements of continuously varying quantities such as size and time, in contrast to the natural numbers 1, 2, 3, …, arising from counting.

If 5 tractors can plow a field in 4 hours, how many hours will it take 3 tractors to plow the field?
Mrac [35]

The number of hours required for 3 tractors to plow the field is 2.4 hours

<em><u>Solution:</u></em>

Given that 5 tractors can plow a field in 4 hours

We have to find out number of hours required for 3 tractors to plow the field

5 tractors can plow a field in 4 hours, So time taken for 1 tractor

\text{ time taken for 1 tractor } = \frac{\text{ time taken for 5 tractor}}{5}

\text{ time taken for 1 tractor } = \frac{4}{5} \text{ hours }

<em><u>So time taken for 3 tractors is given as:</u></em>

time taken for 3 tractor = time taken for 1 tractor x 3

\text{ time taken for 3 tractor} = \frac{4}{5} \times 3 = \frac{12}{5}

\rightarrow \frac{12}{5} = 2.4

So number of hours required for 3 tractors to plow the field is 2.4 hours
