The region(s) represent the intersection of Set A and Set B (A∩B) is region II

<h3>How to determine which region(s) represent the intersection of Set A and Set B (A∩B)?</h3>

The complete question is added as an attachment

The universal set is given as:

Set U

While the subsets are:

  • Set A
  • Set B

The intersection of set A and set B is the region that is common in set A and set B

From the attached figure, we have  the region that is common in set A and set B to be region II

This means that

The intersection of set A and set B is the region II

Hence, the region(s) represent the intersection of Set A and Set B (A∩B) is region II

to fill a coffee mug at a local shop costs $2.50. the shop sells coffee beans foe $12 per pound. each pound makes enough coffee
myrzilka [38]

Answer:

There are a few possible answers so read explanation, but the one I will put up here is:

20.83

Step-by-step explanation:

First you have to find how much 100 cups of coffee costs in store.

To do this you will multiply 2.50 by 100 and get 250. So now we know 100 cups of coffee in store costs $250 whereas 100 cups at home is $12.

To find how many times greater the price in store is compared to the at home brew, you have to divide 250 by 12 and get 20.8333333....

We don't stop there though, because it asks us to approximate. I am not sure what it would like us to round to, but here are some possible approximations:

  1. 20.83
  2. 20.8
  3. 21

Any of those re reasonable approximations, you choose whichever you think the question wants, or whatever your teacher asks for.

Hope this helps

marusya05 [52]

Answer:

Option B.

Step-by-step explanation:

In the question the number categories on the spinner are not given.

Consider there are 5 different categories on the spinner.

A = Spinner land on "Action".

So, probability of  land on "Action" is

P(A)=\frac{1}{5}

Number of spins, n= 60 times

The expected number of land on "Action" is

\text{Expected value}=n\times P(A)

\text{Expected value}=60\times \frac{1}{5}

\text{Expected value}=12

Therefore, the correct option is B.
