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.
The outside arcs for a circle enveloping a triangle will always equal 360.
Set up an equation that has all arcs equal 360:
Combine like terms:
Subtract 60 from both sides:
Divide both sides by 10 to get x by itself:
We can now find the values of the arcs:
All three arc lengths are different, which means that the triangle's side lengths are all different. This makes the triangle a
scalene triangle.
Answer:
C
Step-by-step explanation:
If they were to do a survey there would be different products everyone suggests
Answer:
8 : 27
Step-by-step explanation:
The ratio of the volumes is the ratio of the scale factor cubed
2^3 : 3^3
8 : 27
