Answer
105
Step-by-step explanation:
first bring 3 to the second power and get 9
then you have 7+8(9-2)
then add 7+8 and get 15
then you have 15(9-2)
then subtract 9-2 and get 7
then you have 15(7)
then times them and get 105
The equation has 1 solution
Answer:
-8±√17 and -8±6√2
Step-by-step explanation:
1. x+16/x=4, x^2+16-4x=0. x=-8±√17
2. x+16/x=8, x^2+16-8=0. x=-8±6√2
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
