Answer:
0.11% probability that you must ask 20 people to find one person without a social networking site
Step-by-step explanation:
We have these following probabilities:
75% probability that a millenial has a profile in a social netwok site.
25% probability that a millenial does not have a profile in a social network site.
What is the probability that you must ask 20 people to find one person without a social networking site?
The first 19 people have a social network site, each with a 75% probability.
The 20th person does not have a profile, with a 25% probability.
So
0.11% probability that you must ask 20 people to find one person without a social networking site

d=4 that is the common difference
Answer:
33.46
Step-by-step explanation:
Using the cosine rule;
b² = a²+c²-2accosB
b² = 51²+38²-2(51)(38)cos41
b² = 2601+1444-2(51)(38)cos41
b² = 4045-2,925.25
b² = 1,119.74
b = √1,119.74
b = 33.46
Hence the value of b to nearest hundredth is 33.46
