Answer:
Step-by-step explanation:
We would assume that a randomly selected registered voter, x is classified as a conservative or not. It means that there are only 2 possible outcomes. Thus, it is a binomial probability distribution and the probability of success, p is that a randomly selected voter is classified as a conservative. Therefore,
p = 20% = 20/100 = 0.2
Number of trials, n = 10
Number of success, x = 6
The probability that six out of 10 would be conservatives is expressed as
P(x = 6)
Using the binomial probability calculator,
P(x = 6) = 0.0056
Answer: D
1/2x-1+4=x
1/2x-x=-3
-1/2x=-3
x=6
The formula is : 3.14 times r(radius)^2
Answer: B: 70, 80, 30
Step-by-step explanation:
An acute triangle has all 3 angles at less than 90 degrees, therefore the answer is B because its the only one that has all three at <90

When a quadratic equation is in the vertex form,
the equation of axis of symmetry is simply
The given quadratic equation is
We can rewrite this as
We now compare to
We have
Therefore equation of axis of symmetry is:
