Gwar [14]3 years ago

Answer:

120 different slates of candidates are possible.

Step-by-step explanation:

The order is important.

For example, a slate of John, Rose and Elisa means that John is the chairperson, Rose is the secretary and Elisa is the treasurer. If two of them are exchanged, their roles will also be changed. So we use the permutations formula to solve this question.

Permutations formula:

The number of permutations of x elements from a set of n elements is given by:

P_{n,x} = \frac{n!}{(n-x)!}

In this problem, we have that:

6 members will be chosen for 3 roles. So

P_{6,3} = \frac{6!}{(6-3)!} = 120

120 different slates of candidates are possible.

The least total cost method (LTC) lot-sizing technique calculates the order quantity by comparing the carrying cost and the setu
rewona [7]

Answer:

True

Step-by-step explanation:

The least total cost method is the method in which the total cost of the ordering cost and the total carrying cost is equal among various lot size available.

The order quantity should be choose when the total ordering cost and the total carrying cost equal to each other

The formula to compute the economic order quantity is shown below:

a. The computation of the economic order quantity is shown below:

= \sqrt{\frac{2\times \text{Annual demand}\times \text{Ordering cost}}{\text{Carrying cost}}}

It is always be expressed in units

The formula to compute the ordering cost is

= \frac{Annual\ demand}{Economic\ order\ quantity}\times ordering\ cost\ per\ order

And, the formula to compute the carrying cost is

= \frac{Economic\ order\ quanity}{2}\times carrying\ cost\ per\ unit

Hence, the given statement is true

Find the value of x in the given figure using parallel lines
pantera1 [17]

Answer:

x = 18 degrees

Step-by-step explanation:

because lines n and m are parallel, 3x and 126 are same side interior angles. This means that when added up they equal 180, so make an equation as so:

3x + 126 = 180

Solve for it and x will equal 18.

Perimeter of a rectangle is 96m. if it's length is 3 times it's width , then find it's length and breadth.​
Stolb23 [73]

Answer:

breadth = 12

length = 36

Step-by-step explanation:

let the breadth be 'x'

length = 3x

p = 2l + 2b

96 = 2(3x) + 2(x)

x = 12
