I think that the answer for that one is A
Answer: 11
Step-by-step explanation:
Since the equation of circumference is 2(r)pi
if 22pi=2(r)pi
then 22=2r
22=2r
r=11
A
you have to solve x^2+x-5=0
So x=(-1 +/- sqrt(1^2+4*1*5))/2
x=(-1 +/- sqrt(21))/2
Answer:
0.0019390
Step-by-step explanation:
10% of people do not like the taste of cilantro
A researcher takes a random sample of 15 people and surveys whether they like cilantro
Use the binomial distribution to compute the probability that exactly 6 of the people in the sample do not like cilantro.
Probability of success = 0.10 = p
Probability of failure = 0.9 =q
n = 15
r = 6
Formula : 



Hence the probability that exactly 6 of the people in the sample do not like cilantro is 0.0019390
