A package delivery system divides their packages into weight class. The packages in the 14-20lb weight class are uniformly distributed, meaning that all weights are equally likely to occur. What is the probabilyt that a package will be less than 18 lbs?

Answers

Answer 1

Answer:

4/7 or 57.14% in percentage form

Explanation:

If a package in that weight class can be any weight between 14-20lb then there are a total of 7 different possible weights. Out of all of these only 4 are actually less than 18lbs, those weights are 14, 15, 16, 17. Therefore, since weights are evenly distributed in that weight class then the possibility of a package being less than 18lbs would be

4/7 or 0.5714 or 57.14%

Joe is playing a game in which he has to roll two six-sided dice. In his past ten rolls, he has rolled a sum of one 2, two 5s, three 7s, two 8s, one 10, and one 12. The weighted mean of all of Joe’s dice rolls is __________.

Answers

Answer:

The weighted mean of all of Joe’s dice rolls is 7.1.

Explanation:

Since Joe is playing a game in which he has to roll two six-sided dice, and in his past ten rolls, he has rolled a sum of one 2, two 5s, three 7s, two 8s, one 10, and one 12 To determine the weighted mean of all of Joe's dice rolls, the following calculation must be performed:

(2 + (2 x 5) + (3 x 7) + (2 x 8) + 10 + 12) / 10 = X

(2 + 10 + 21 + 16 + 10 + 12) / 10 = X

71/10 = X

7.1 = X

Thus, the weighted mean of all of Joe’s dice rolls is 7.1.

At its current​ short-run level of​ production, a​ firm's average variable costs equal ​$25 per​ unit, and its average fixed costs equal ​$10 per unit. Its total costs at this production level equal ​$2,100. What is the​ firm's current output​ level? nothing units. What are its total variable costs at this output​ level? ​$ nothing. What are its total fixed​ costs? ​$ nothing.

Answers

Answer:

Current output level ⇒ 60 units Total variable costs ⇒ $1,500Total fixed costs ⇒ $600

Explanation:

Variable costs are $25 per unit and Fixed costs are $10 per unit.

Total costs are therefore:

= 25 + 10

= $35

Current output level:

= Total costs / Unit costs

= 2,100 / 35

= 60 units.

Total variable costs:

= Unit variable cost * number of units

= 25 * 60

= $1,500

Total Fixed costs:

= Total costs - Variable costs

= 2,100 - 1,500

= $600
