1*1.50=1.5, the second is 7.50, 12 ?

Since it's a constant amount, divide $4.50 by 3 to get $1.50 each.

This also works for $13.50; divide $13.50 by 9 to get $1.50.

To check your answers:  is 1 x $1.50 = $3.00? If not, what should it be?

Also: is 5 x $1.50 = $7.50?

And is 8 x $1.50 = $6.00?

Using "W" to represent a win by the Bad News Bears and an "L" to represent a loss, the possibilitIes are:

W·W·W

W·W·L·W

W·W·L·L·W

W·L·W·W

W·L·W·L·W

W·L·L·W·W

L·W·W·W

L·W·W·L·W

L·W·L·W·W

L·L·W·W·W

Replace each "W" with 2/3 and each "L" with 1/3, do the indicated multiplications and add the results to get the answer.

Not much.  Here's how to do it.

What is 25 to the fourth power?          

To do it manually:               Multiply 25 x 25 x 25 x 25 and you'll get the answer. 

                                          (Note that there are 4 of those 25's.) 

To do it on a calculator:      Key in 25

                                          Tap the X^Y button             

                                          Tap the 4 button             

                                          Tap the = button.

I just hurriedly wrote down the first ones I thought of.  As I continued thinking, I realized there are lots of them.

5 & 15 ..... 6 & 26 ..... 7 & 39 ..... I gues the examples go on forever.

I answered this just a day or two ago. Go find it.

To me it implies either or both.  It only excludes the 3 that do not play either.  That is why I believe the answer to be simply 24/27

There’s 27 students, 18 play basketball and 16 play baseball. 3 students play neither sport. What’s the probability that a student chosen randomly from the class plays basketball or baseball?

Actually the diagram was not needed.  It is just    24/27 = 8/9

nvm solved it, just factor 2 out of the numerator and 1+sin(x) cancels left with 2/cos(x)

EXACTLY

Try this one.  

y= 4(sinx)-3

what will be

a) midline

b) y intercept

c) wavelength

d) amplitude

Answer first

Then try to freehand draw. It is good getting practice sketching these by hand.

AND then check using Desmos.

Excellent

Think back to what we were doing before and answer those standard questions for this one.

(then check with desmos)

y=5+sinx           Notice it is plus NOT muliply

Your observation is excellent.

however,

y=sinx     is the same as    y=1sinx = 1*sinx      

So   The amplitude is 1 

So I will go back to a question I asked earlier

So for y=10sinx

what will be

a) midline

b) y intercept

c) wavelength

d) amplitude

After you answer, draw it using Desmos and check that your answers are correct.

Thanks Tomsun and guest answerer,

The asker may like to note this.

Some people here, including me, will not answer questions that are not presented properly.

1. A) The amplitude should be 1. Should the wavelength be 2π? The midline should be y=0, and the y-intercept should be 0 as well.

1. B) Is it multiplied by -1?

2) The amplitude should be 3. Should the wavelength be 2π as well? I assume the midline is also y=0, same with the y-intercept.

3) Should the amplitude be 4? The wavelength should be 2π as well again? The midline is y=0; the y-intercept is 0. 

Given I'm not blind, I'm noticing these all share the same qualities except their multiplier, which dictates their variety in amplitude? Hopefully, that's all correct!

A bag contains 4 orange balls and 5 purple balls. Raina draws three balls out of the bag, one at a time, without replacement. What is the probability that the colors of the balls alternate?

e.g.

P(pop) = \(\frac{5}{9}*\frac{4}{8}*\frac{4}{7}\)

The numbers get smaller as the balls are removed.

For instance if there are 4 orange, and 5 purple balls and you remove a purple one

then for the next drawer there is only 4 orange, 4 purple and 8 altogether.

Hi there...

The question was "What’s the probability that a student chosen randomly from the class plays basketball or baseball?".

The use of "OR" in a sentence implies "EITHER" not "BOTH".
And as such saying "24 in 27" is good enough of an answer in this context.
If you first decide to nitpick, you should add "14 in 27" to the list as well.

Kind regards

Hi there...

If Robert runs at a pace of 1 Lap per minute, and had already finished 4 Laps when he was joined by Wilson on the field, who runs at a pace of 5 Laps per minute.
A minute later they would have both finished 5 Laps.

I hope that helped a bit?

Kind regards

Also, I'm not sure, but I think the answer is an integer. Anyway, thank you for your time and response. <3
