uhhh what kind of 6 grade math is this?
Answer:
Step-by-step explanation:
Given that a sphere has one diameter having endpoints (2,1,4) and (4,3,10)
We can find the mid point of these two points and that would be the centre
If we find distance between these two points that would be twice radius.
Distance = 2r =
So radius =
Centre of sphere = mid point of two points
= (3, 2, 7)
Using centre radius formula sphere has equation as
Answer:
The probability that a book picked at random is either a work written by an author who writes only nonfiction or a work written by a man is 75.8%.
Step-by-step explanation:
The probability, in this case, has to be calculated using the sum rule because the events are independent.
P = P(men) + P(non-fiction) - P(men non-fiction); where P is the probability. It means the probability that the random book was written by a man plus the probability that the random book was non-fiction minus the probability that the random book was written by a man who writes non-fiction. The probability that the random book was written by a man who writes non-fiction has to be subtracted, if not you will be duplicating it.
Facts:
P(men) = 60% = 99/165
P(non-fiction) = 40% = 66/165
P(men non-fiction) = 40/165
P = P(men) + P(non-fiction) – P(men non-fiction)
P = 99/165 + 66/165 – 40/165
P = 125/165
P = 0.758 or 75.8%

Answer:
r = the square root of V/ pi*h
Step-by-step explanation:
You can find this by seperating r from the rest of the equation. You will have to divide V by pi and h, and then take the square root of it all, then r will be singled out on one side with the equation on the other. I added a picture so that it will be much more clear and simple.
