X/sin 42 = 43/sin 87
x = (43 * sin 42)/(sin 87)
x = 28.812
Answer: 28.8
Answer:
Probability
Step-by-step explanation:
Probability of an event is how likely that event is to happen. And it is denoted by letter P and calculated by the formula below:
P(E) = number of possible outcome/number of the total event sample
P(E) = n(E) / n(S)
Hello I hope you are having a Great day :)
Your question, 296.32 divided by 4
Your answer would be 74.08
Hopefully that helps you :)
Variance = summation of (x - mean)^2 all divided by the number of dataset.
mean = (17 + 5 + 11 + 1 + 11)/5 = 9
Variance = [(17 - 9)^2 + (5 - 9)^2 + (11 - 9)^2 + (1 - 9)^2 + (11 - 9)^2]/5 = (8^2 + (-4)^2 + 2^2 + (-8)^2 + 2^2}/5 = (64 + 16 + 4 + 64 + 4)/5 = 152/5 = 30.4
