Answer:
1364
Step-by-step explanation:
∑ means that to add values
So n goes from 1 to 5 and you have to add them from 1 to 5
∑n=1 to 5 4^n = 4^1 + 4^2 + 4^3 + 4^4 + 4^5
4^n means that 4 is n times if 4^3 its mean that 4 is 3 times
= 4 + 16 + 64 + 256 + 1024
= 1364 Answer
I hope you got the idea. Thanks
The probability of multiple events happening is calculated by multiplying the probabilities of each event together. This is the case if each event is independent of the other events.
For a fair coin, the probability of tails is 1/ 2 or 0.5, so the probability of all tails in 10 tosess is (1/2)^10 = 1/1024 = 0.0009765625
Correct answer: D
They should still be 280 miles apart on the map i belive.
Opposite sides of a parallelogram are congruent, so you know that 2x + 2 = 3x - 3. start by adding 3 to both sides to get 2x + 5 = 3x. then subtract 2x from both sides to get 5 = x.
