Answer:

look below

Step-by-step explanation:

The probability of each of the cards can be found by dividing each of them by the sum of all the numbers:

P of picking card with star:

25/50=0.5

Card with square:

15/50=3/10=0.3

Card with circle: 10/50=1/5=0.2

We can then put these values into parts a,b,c, and d:

a) 3/10 chance or 30%

b) 1/5 chance or 20%

c) 1/2+1/5=7/10 chance or 70%

d) 1-0.3-0.2=1/2 chance or 50%

Which of the following describes the end behavior over the domain of the square root function graphed above? Please HELP!!!!!!!!
PilotLPTM [1.2K]
Short Answer A
Comment

It's a good thing that the domain is confined or the graph is. That function is undefined if x < - 3 

At exactly x = - 3, f(x) = 0 and that's your starting point.

So look what happens to this graph. If x = 0, f(0) =  y = 3. So we are starting to see that as x get's larger so does f(x). The graph tells us that x = 0 is bigger than x = - 3.

Let's keep on plugging things in.
As x increases to 5, f(5) = 5. x = 5 is larger than x = 0, and f(5) > 3.

One more and then we'll start drawing conclusions. If x = 9 then f(9) = y =  6. 
x = 9 is larger than x = 5. f(9) = 6 is just larger than f(5) which is 5

OK I think we should be ready to look at answers. There's nothing there that makes the answer anything but a. Let's find out what the problem is with the rest of the choices.

B
The problem with B is that as x increases, f(x) does not decrease. We didn't find one example of that. So B is wrong.

C
C has exactly the same problem as B. 

D
The second statement in D is incorrect. As x increases f(x) never decreases. No example showed that.

The answer is A <<<< Answer.

Point F is a centroid of the triangle BDE. If AB = 24 cm, what is BE?
Alex17521 [72]

Answer: i know this is way late, but it’s 48

Step-by-step explanation:

Since point A is the separation of BE, both sides of the separation are equivalent, the are congruent. Since AB=24, you add 24+24 to get 48.

(I also just answered this question on homework and got it right, this is just how I did it.)
