Answer:
-2.5
Step-by-step explanation:
-30 + (-15) + (-20) + 55 = -10. Then you divide it by how many numbers there are (4). Which equals - 2.5. If this is wrong, then round up to -3.
Answer:
The answer is yes.
Step-by-step explanation:
All you have to do is substitute the y, which is 5, and the x, which is 2, into the equation. When you solve it the answer in the end will be 5=5, which means that point (2,5) does line on that line.
The answer would be 203 because if u multiply u get x time 3
It really depends on the situation as probability depends on logic more than simple mathematical equations. However you must keep in mind a few principles:
1- P = number of possible outcomes of the event / total outcomes
2- P always less than or equal to 1.
3- For independent events A and B to occur simultaneously, P= P(A) x P(B)
You can send me the question you’re stuck at for further help.
Perhaps you mean to find the volume under

? It seems like you have to rely on calculus otherwise (in the case that you indeed mean

).
Assuming this, note that

describes the top half of a sphere with radius 8, which means the volume below this surface over the disk

is simply half the volume of the sphere. Thus the volume is
