Answer: d) 0.238
Step-by-step explanation:
We would assume binomial distribution for the number of men sampled. The formula for binomial distribution is expressed as
P(x =r) = nCr × q^(n - r) × p^r
Where
p represents the probability of success.
q represents the probability of failure.
n represents the number of samples.
From the information given,
n = 10
p = 65% = 65/100 = 0.65
q = 1 - p = 1 - 0.65 = 0.35
The probability that exactly six of them will consider themselves knowledgeable fans is expressed as P(x = 6). It becomes
P(x =6) = 10C6 × 0.35^(10 - 6) × 0.65^6
P(x =6) = 10C6 × 0.35^4 × 0.65^6
P(x =6) = 0.238

Answer:
18.66 ft/s
Step-by-step explanation:
The distance between you and the elevator is given by:
The rate of change for the distance between you and the elevator is given by:
Applying the chain rule:
Therefore, at x=300 and y = 500, dy/dt is:
The elevator is descending at 18.66 ft/s.
