Answer:
b. Not binomial: there are more than two outcomes for each trial.
Step-by-step explanation:
Binomial probability distribution:
We need
Fixed number of trials.
Independent trials.
Each trial can be reduced to a yes/no proposition.
Rolling a single "loaded die 19 times, keeping track of the numbers that are rolled.
There are six possible outcomes(1,2,3,4,5,6), so cannot be reduced to a yes/no proposition, and the answer is given by option b.
Connect c to e and then e to a
The easiest ways is to use the quadratic formula that is:
x' = [-b+√(b² - 4ac)]/2a and x" = [-b -√(b² - 4ac)]/2a
Solving : 2x² + 5x - 11 = 0, gives:
x' = [-5+√(25 - 4(2)(-11)]/4 and x" = [-5-√(25 - 4(2)(-11)]/4
x' = (-5+√113)/4 & x" = (-5-√113)/4
Answer:
-4

Answer: 17.0
Step-by-step explanation:
According to the question the height is 18. sin 71 = 18x9455 = 17.019 = 17.0
