Hello!


The set X ∪ Y, can be found by combining the given sets of the sets into one set.


You are given set X = {5, 10, 15} and set Y = {3, 6, 9, 12, 15}.

∪ represents union, so you put these sets together.

Also, since the element 15 is in both sets, it should be in the X ∪ Y set, once.


Therefore the answer is A, X ∪ Y = {3, 5, 6, 9, 10, 12, 15}.

What's the probability of pulling two red cards in a row from a deck of cards?​
monitta

Hey there! I'm happy to help!

Let's say that we don't have jokers. In that case, there are 52 cards, and half of them are red (so 26 are red). The probability of pulling a red card once is 1/2 since half the cards are red.

If we pick one out, there are only 51 total cards left and 25 red cards. So, the probability of picking one again would be 25/51.

We multiply the probabilities of these two events to find the probability of them both happening.

1/2×25/51=25/102

The probability of picking two red cards in a row is 25/102 or around 24.5%.

Have a wonderful day! :D

So, you just have to recognize the line splitting the circle in half, line LJ.  So, if JC (arc) is 94, then do 180-94=86.  ∠LJC is an inscribed angle, so it's half of 86, which is 43°.

43° is your answer.

In sweden, vat is at 25%. ella buys a hat in sweden for 50 sek( swedish krona). find the vat paid by ella.
V125BC [204]

If Ella buys a hat in Sweden for 50 SEK with 25% VAT, then the VAT paid by Ella is 12.5 SEK

A Value-Added Tax (VAT) is a consumption tax assessed on the value added in each production stage of a good or service

Given,

The price of hat = 50 SEK

VAT =25%

The amount paid as VAT= 50(\frac{25}{100})

=12.5 SEK

Hence, If Ella buys a hat in Sweden for 50 SEK with 25% VAT, then the VAT paid by Ella is 12.5 SEK
