Probability of success =

   (number of possibilities that would be considered successful)
divided by
   (total number of different possible outcomes) .

Total number of different possible outcomes =

   total number of different possible values of the last 2 digits

   = the quantity of numbers from 00 to 99

   = 100 of them .

The number of possibilities that will match your age = only 1 .

Probability that the last 2 digits match your age = 1/100 = 0.01 = 1 % .

{-210, -156, -366,-471, -108,-627, -579}

Andru [333]

Option D I and IV only is correct option

Step-by-step explanation:

We need to identify that the numbers {-210, -156, -366,-471, -108,-627, -579} belong to which of the following set of numbers.

I. Rational Numbers

II. Natural Numbers

III. Whole Numbers

IV. Integers

We will consider each option

Rational numbers: numbers that can be written by dividing two integers. They can be positive or negative.

all the numbers given can be divided by 1 to make them fractions. So all numbers are rational numbers.

Natural numbers: numbers that are positive integers excluding 0 i.e 1,2,3...

So, the given numbers are not natural numbers

Whole numbers: all natural numbers including 0. These are positive numbers. So, the given numbers are not whole numbers

Integers: it is a whole number (not fraction) that can be positive,negative or zero. So, the numbers given are integers.

So, Option D I and IV only is correct option

Complete the table by converting each decimal to a fraction. Show your work. Repeating decimals. 0.2, 0.5, 0.7

Helga [31]

Answers

Part 1 = 2/9

Part 2 =5/9

Part 3 =7/9

Explanation

To convert the a repeating decimals this are the steps;

Part 1

Let x = 0.222222... (i)

10x = 2.222222... (ii)

Subtract equation (i) from equation(ii)

10x = 2.222222....

-x = 0.222222....

9x = 2.00000..

∴ 9x = 2

Divide by 9 both sides;

x = 2/9

Part 2

Let x = 0.5555...

10x = 5.5555...

subtract equation (i) from equation (ii).

10x = 5.5555..

- x = 0.5555..

9x = 5.0000..

∴ 9x = 5

x = 5/9

Part 3

Let x = 0.7777....

10x = 7.7777...

Subtracting equation (i) from equation (ii)

10x = 7.7777...

-x = 0.7777...

9x = 7.000..

∴ 9x = 7

x = 7/9

Pattern noted

When converting the repeating decimals to fraction only one number was repeating. This made the three decimals have the same fraction.

Mark achin sells 3,600 electric motors each year. the cost of these is $200 each, and demand is constant throughout the year. th

Vedmedyk [2.9K]

Summary of information:
total output = 3600 units per year
split into 18 equal orders
cost per order = $40
cost to store a unit for one year = $20
lead time (i.e. storage before shipping) = 5 days

Solution:

quantity split into 18 orders, so 3600/18= 200 units per order.
Order cost = $40 * 18 orders = $720 ..........................(A)
Storage cost:
Each order has 200 units, stored for 5 days = 200*5=1000 unit-days
storage needed for 18 orders = 1000*18 = 18000 unit-days = 50 unit-years
Total storage cost = 50 unit-years * $20 / unit year = $1000...........(B)

Total ordering cost = (A) + (B) = $720+$1000 = $1720
