Both.

Is this a bar graph that is on a website or a self-created one???

Why did Melody tell me that I have your specs?

Kind of, Chris!

Yeah...think about this, DS. If we have 50%, that's just 1/2. And 1/2, as a decimal, is just .50......Notice that we just dropped the % sign and moved the (understood) decimal two places to the left.

Does that make sense???

You're right Chris, there is some double counting in the way I did it!

So the answer is 13.7457?

Thank you. Let me try the square root thing.

√

I did it!

13.7457  ....   When we have a percent....Drop the percent sign and move the decimal two places to the left.....

I get something a little different here....at least two DK albums means we want to choose either 2, 3 or 4 of Diana Kroll's albums.

Choosing 2 we have C(5,2)*C(11,2) = 550 ways

Choosing 3 we have C(5,3)*C(11,1) = 110 ways

Choosing 4 we have C(5,4)*C(11,0) = 5 ways

So 550 + 110 + 5 = 665 ways

And that's the direct method

For the indirect method, we want to take all the possible ways of choosing 4 albums and subtract the ways that don't include choosing just one or none of the DK albums...so we have....

C(16,4) - C(5,1)*C(11,3) - C(5,0)*C(11,4) = 665 ways

25% of 100=25

You're welcome!

Thank u very much DragonSlayer!

Nice pictures. They are neat.

The answer is 400. Divide 600 by 3 and you get 200, or 1/3. So, you add 200 more so that equals 400, or 2/3 of 600. Hope that helps.

Question 1)140

Question 2)-25 square root 10

4√7 times 5√7 = 20√49 = 20*7 = 140

5√-5 times 5√-2  = 5i√5 * 5i√2  =  25i²√10 = -25√10

You're welcome.

okay!thanks for the advice!

Thumbs up from me!

im sorry not studied that yet!

but i wish u luck!

See Chris's calculations below.

Okay. Think.

"after you take the cubed root, you remove the radical. dont forget the x's. the cubed root of x^6 is x^3"
