Marc has the fastest average speed in miles per minute as he ran a mile in 6 minutes.
Answer:
D
Step-by-step explanation:
First of, let's make a table for y = cos(x)
(x , y): (0 , 1) (π/2 , 0) (π , -1) (3π/2 , 0) (2π , 1)
Now, making a table for y = 2cos(x) is simple. We just have to multiply all the y-values from the previous table by 2.
(x , y): (0 , 2) (π/2 , 0) (π , -2) (3π/2 , 0) (2π , 2)
Graphing these coordinates, we find that the answer is D.
Answer: The protons and neutrons.
Answer:
a) This will result in a binomial distribution.
b) This will not result in a binomial distribution.
Step-by-step explanation:
Binomial probability
The binomial probability is the probability of exactly x successes on n repeated trials, and each trial can only have two outcomes.
So:
(a) The National Health Institute checks on 100 people who had a certain type of cancer in the year 2000 and records whether they are alive or not.
Fixed number of trials(each person checked is a trial) with a fixed probability(there is a probability that the person who had that type of cancer is alive).
So it results in a binomial distribution.
(b) Calling all your friends until you have 2 people willing to play on your volleyball team.
There is not a fixed number of friends that are going to be asked, so this does not results in a binomial distribution.
