Pirate Jack has an equal number of gold and silver coins. If Pirate Jack splits all of his coins into 7 equal piles for his parr

Alona [7]

The least possible number of coins Pirate Jack has, is 81 coins.

Step-by-step explanation:

Given,

When the coins are divided into 7 equal piles, 4 coins are left.

When the coins are divided into 11 equal piles, 4 coins are left.

We will take LCM of both 7 and 11.

7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, ....

11 = 11, 22, 33, 44, 55, 66, 77, 88, ...

The least common multiple of 7 and 11 is 77.

As 4 coins are left, therefore, we will add those coins.

Total possible coins = 77+4 = 81

The least possible number of coins Pirate Jack has, is 81 coins.

Your company is going to build 4 factories that will use the latest robot technology. One will make prefab buildings, another se

ch4aika [34]

Answer:

a) 230300 ways

b) Check Explanation

Step-by-step explanation:

a) This is a combination problem,

We require how many ways 4 factories be placed among 50 states.

Mathematically, that is

⁵⁰C₄ ways = 230300 ways

b) If you have no idea which states will be chosen, what is the probability that all 4 factories will be located in the mid-Atlantic region.

This can be done in two ways

Method 1

The mid Atlantic region is one of 9 geographic divisions in the US

Probability of 1 factory being located in this geographic region = (1/9)

The probability of the 4 factories being in just this region = (probability of locating one factory in this region)⁴ = (1/9)⁴ = 0.0001524

Method 2

The mid Atlantic region contains only 3 out of 50 states. (New York, New Jersey, Pennsylvania)

Probability of 1 factory being located in one of the 3 stares = (3/50)

Probability of locating all four factories in one of the states in this region = (3/50)⁴ = 0.00001296.
