12, 18, x, and 5 are used to calculate an average of 13. What is the missing number?

Answers

Answer 1

Answer:

17

Step-by-step explanation:

Given the data:

12, 18, x, 5

Average of the numbers = 13

The value of x will. Be

Sum of 12, 18, x and 5 divided by the number of data values.

Mean(average) = Σ(X) / n

n = number of values

13 = (12 + 18 + x + 5) / 4

13 = (35 + x) / 4

13 * 4 = 35 + x

52 = 35 + x

x = 52 - 35

x = 17

Graham decided to play football this year instead of getting a part-time job. Last year he made about $1,100 during football season. He also spends about $9 on eating out after each game. His team plays a 10-game season. What is his opportunity cost of playing football?

Answers

10,091 because it's a 10 season football season and he spends 9 dollars every game

Step-by-step explanation:

The opportunity cost of playing football for Graham is $1,190.

What is the Opportunity cost?

The opportunity cost of certain activity in microeconomic theory is the value or gain given up by engaging in that activity in comparison to engaging in an alternative activity. Simply put, if you do a bone activity, you forfeit the potential to choose another.

Given that Graham made $1,100 during football season. Also, Graham spends about $9 on eating out after each game and his team plays a total of 10 games in a season.

Therefore, the opportunity cost of playing football for Graham is,

Opportunity cost

= Amount that Graham would have made in a part-time job +  Total cost of playing football season

= $1,100 + (Number of games × Amount spend in a single game)

= $1,100 + (10×$9)

= $1,100 + $90

= $1,190

Hence, the opportunity cost of playing football for Graham is $1,190.

What is the volume of a rock with a density of 45 g/mL and a mass of 855 grams?

Your answer must have units

Answers

Answer:

  19 mL

Step-by-step explanation:

You want the volume of a rock with density 45 g/mL and mass of 855 g.

Volume

The units of density are mass per volume, so we can find the volume by dividing the mass by the density. The units basically tell you how to work the problem.

  [tex]\dfrac{855\text{ g}}{45\text{ g/mL}}=\dfrac{855}{45}\,\dfrac{\text{g$\cdot$mL}}{\text{g}}=\boxed{19\text{ mL}}[/tex]

__

Additional comment

Sometimes we like the volumes of things that aren't liquid to be expressed in cubic units. 1 mL = 1 cm³, so the volume could be described as 19 cm³.
