Answer:
a) Mean(x) = 0.40
b) Variance(x) = 0.24
Step-by-step explanation:
From the information given, the process is Bernoulli process, since the team can run or pass the ball into the end zone to score two points only. We are not told the number of times. Thus, <em>n </em>is unknown. That is, we are not told how many times the team successfully pass the ball into the end zone.
By Bernoulli process, the mean and variance are given as follow:
Mean = p
Variance = pq. This is the same as p(1-p)
Where p is the probability that this play is successful and q is the probability that this play is not successful.
Step-by-step explanation:
D=37.68
R=d/2 = 37.68/2 =18.84
Volume of sphere = 4/3 πr3
Now,
4/3*22/7*(18.84)3
=88/21*6687.17
=588470.96/21
=28022.42 mm3. ☑️

Answer:
0.52763 is the probability that the time between the next two calls will be 54 seconds or less.
0.19285 is the probability that the time between the next two calls will be greater than 118.5 seconds.
Step-by-step explanation:
We are given the following information in the question:
The time between telephone calls to a cable television service call center follows an exponential distribution with a mean of 1.2 minutes.
The distribution function can be written as:
The probability for exponential distribution is given as:
a) P( time between the next two calls will be 54 seconds or less)
0.52763 is the probability that the time between the next two calls will be 54 seconds or less.
b) P(time between the next two calls will be greater than 118.5 seconds)
0.19285 is the probability that the time between the next two calls will be greater than 118.5 seconds.
Answer:
your not an idiot
They are not equivelent.
Step-by-step explanation:
You always solve in the parenthesis first... so in the first equation we want to add 12+10 first to get 22 + 7 which is 29.
In the second equation, we add the parenthesis firt, 10 + 12=22 then add 12 to get 34. Have a good day!
