True
Area of a circle = πr^2
So if r = 10: area = π*10^2
= 100π
Surface area of a sphere = 4πr^2
If r = 5: surface area = 4π*5^2
= 4π*25
= 100π
Answer:
(D)Lucita's estimate is too high.
A single die is consists of 6 sides. The sides consists of one to six dots. Therefore, tossing a single die will have 6 equal probabilities. That is, one to six dots.
(A) There are 3 numbers from 1 to 6 that are less than 4. Those are 1, 2, and 3. So, there are 3 possible outcomes. So, the probability of the event A happening is equal to 3/6 or 1/2.
(B) There are 2 numbers less than or equal to 2. Those are 1 and 2, itself. The probability of this event happening is 2/6 or 1/3.
(C) There are 3 numbers from 1 to 6 that are greater than 3. Those numbers are 4, 5, and 6. The probability of this event is equal to 3/6 or 1/2.
I believe that the domain of the function is continuous because it is the equation of a line. For all points of x, there will by a value of r (in this case) that will not be repeated, so therefore it is a function with no breaks. I hope this helps :-)
as you already know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".
