Answer:

D (sweater,shorts and jeans)

Step-by-step explanation:

Sweater = 40 = original price

Sale price of sweater = 32.00

Discount = 40-32 = 8 dollars

in terms of % , it will be 8/(original price) * 100

= 8/40*100 = 20% discount.

Similarly

shorts has discount of 6/30*100 = 20 %

Similarly jean has discount of

10/50*100 = 20 %

shirt have discount of 10/45*100 = 22.22%

so sweater,shorts and jeans have same discount. (choice D)

2.8 meters linen divided into 45 cm pieces = # of pieces and waste

pogonyaev

2.8 meter= 2800cms

To solve this, we can create a simple algebraic equation:
45x=2800
Divide both sides by 45.
(45x)/45=(2800)/45
x=62.222

You can make 62 full pieces.

To find the waste, multiply the numbers of pieces by the length of each.
62*45
=2790
2800-<span>2790
=10 centimeters

There would be 10 centimeters of wasted linen.

Hope this helps!

Answer:

The probability that the sum of the numbers rolled is either a multiple of 3 or an even number is 24/36 = 2/3

The two events are mutually exclusive

Step-by-step explanation:

we first need to create a table of the sample space from the experiment, the sum of the numbers rolled. Find the attached for a depiction of the possible outcomes.

The probability that the sum of the numbers rolled is either a multiple of 3 or an even number will be given by counting the numbers that are either even or multiples of 3 and then dividing by the number of possible outcomes, 36.

In our case this will be;

24/36 = 2/3
