Answer: 1296π
Step-by-step explanation:
To find the surface are if a square, we have to use the formula:
= 4πr²
= 4 × π × 18²
= 4 × π × 324
= 1296π
Therefore, the surface area of the sphere is 1296π
Answer:
Damon is 18, Damon's brother is 11 years old.
Step-by-step explanation:
So, the total age of them both is 29. Damon is 7 years older, so we use 29-7=22. Now, 22 is Damon's brother's age times 2, so we use 22/2=11. 11 is Damon's age is 11+7=18, and His brothers age is 11.
Answer with Step-by-step explanation:
We are given that two events A and B are mutually exclusive.
a.For mutually exclusive events,
Therefore, event A can not occurred if event B has occurred because two events can not occur together.
Answer:No, by definition mutually exclusive events cannot occur together.
b.When two events are independent
Then ,
If two events are mutually exclusive then
Then ,
Therefore,
Hence, we can concluded that events A and B are not independent if they are mutually exclusive.
Answer:Yes,

Answer:
There is one solution
Step-by-step explanation:
You can tell by looking at it that 2x and 3x are different. Both are obtained once the brackets have been removed. So you will get just one answer.
2(x -1) = 3(x - 4) Remove the brackets.
2x - 2 = 3x - 12 Subtract 2x from both sides.
2x - 2x - 2 = 3x - 2x - 12 Combine
-2 = x -12 Add 12 to both sides.
-2 + 12 = x -12 +12 Combine
10 = x
