A. 3/4
B. 2 1/4
C. 1 3/4
D. 3 1/4

Answer:

Step-by-step explanation:

The probability of picking an item A in a box of N items depends on nA, the amount of items A in the box at the time of picking, with the kinda instinctive value:

p = nA / N

then it means that if you have no green ball, the probability is 0/N = 0, if you only have green balls, it means you have a probability of N/N = 1 = 100%, and if you have as many green balls as non-green balls, you have a probability of nA/(2nA) = 0.5 = 50%.

Here the probability of first picking a green ball (nG=5) in a box of N=3+5+2+6=16 for the 1st pick is:

pG1 = 5/16

Now the trick here is that once you picked the green ball, you put it back in the box before picking another ball. So you still have N=16 balls for the second pick, and the probability of picking a yellow ball (nY=6) for the 2nd pick is:

pY2 = 6/16 = 3/8

(it would have been slightly higher, at 6/15, if you did NOT put back the green marble in the box).

Now you want BOTH events to be true. So you want G1 to be true AND Y2 to be true. The two events are independent (the probability of Y2 is 6/16 if you had G1 but is also 6/16 if you failed G1), so the probability of having both is simply done by multiplicating them:

pG1Y2 = pG1 * pG2 = 15/128

Answer:

18

Step-by-step explanation:

So what you need to find is the scale factor which is the scale of the difference between two lengths.

So Figure A is smaller than Figure B, as can be easily detected with our eyes.

Figure A has a ratio of 1/2, as 6/12 is equal to 1/2.

Since B is the original, where A is a scaled version, it must also have the same ratio of 1/2, so twice 9 is 18, which is your answer.

You can also use fractions, by making Figure A into 1/2 because 1/2 = 6/12.

Figure B can turn into 9/x.

Since you know they are scaled factors, they have the same ratio since one is scaled larger or smaller than from the original.

Since it must follow the multiplication of 2 for the side length, 9 x 2 gives your answer.

The difference between the mean and median is that the mean is the average number. f.e: 1, 2, 2, 2, 3, 3, 4, 5 - and if you add all those up, the mean would be 3, or 2.

But the median is the number in the middle Number.

What if you have 2 medians, though?

Well, that’s easy to solve IMO.

F.e: 22, 22, 23, 23, 23, 24, 24, 24, 25, 25

The median is either 23 or 24, right?

Okay. That’s simple. But what exactly do we do?

Let me show you:

So get the sum of 23 and 24, which is 47.

Now divide 47 by 2. And what do we get?

23.5.

Now round that, and you get 24. So 24 is the median!

Hope that helps!

Answer:

mean is the AVERAGE of all numbers

Step-by-step explanation:

because when  you  add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!

and a median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.

Answer:

228

Step-by-step explanation:

is it a rectangle prism?

if so, do This:

2(lb+hb+hl)

Length - 6

width = 4

height = 9

2(24+36+54)

2 ( 114)

= 228

I hope this helps!
