Answer:
30 miles per hour downstream
20 miles per hour upstream
Step-by-step explanation:
divide 4 by 120 to get the rate downstream
divide 6 by 120 to get the rate upstream
Hope this helps :(
Answer:
For this case the probability of getting a head is p=0.61
And the experiment is "The coin is tossed until the first time that a head turns up"
And we define the variable T="The record the number of tosses/trials up to and including the first head"
So then the best distribution is the Geometric distribution given by:

Step-by-step explanation:
Previous concepts
The geometric distribution represents "the number of failures before you get a success in a series of Bernoulli trials. This discrete probability distribution is represented by the probability density function:"
Let X the random variable that measures the number os trials until the first success, we know that X follows this distribution:
Solution to the problem
For this case the probability of getting a head is p=0.61
And the experiment is "The coin is tossed until the first time that a head turns up"
And we define the variable T="The record the number of tosses/trials up to and including the first head"
So then the best distribution is the Geometric distribution given by:

Answer:
-1/3 or -2/6
Step-by-step explanation:
First, you pick two points, I did (-5,10) and (1,8). Then, because slope is y(2)-y(1)/ x(2)-x(1), the equation would be 8-10/1-(-5) which equals -2/6 which simplifies into -1/3.
