After scoring a touchdown, a football team may elect to attempt a two-point conversion, by running or passing the ball into the

snow_tiger [21]

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.

Solve the system of linear equations by elimination −2x+3y=7 and 5x+8y=−2

forsale [732]

You would need to make them eliminate so I would multiply the entire first one by 2.5 to make the X's cancel out. So you would end up with -5X+7.5Y=17.5. The X's would cancel and you would be left with 15.5Y=15.5. So Y=1. Then replace Y into one of the equations. I'm going to use the top again. -2X+3(1)=7. Subtract 3 from both sides to get -2x=4. Divide both sides by negative 2 to get X=-2. So the solution would be (-2,1)

Find the amount of sap the maple syrup producer collected from each tree if the total amount (5 gallons) was redistributed equal

Afina-wow [57]

The picture in the attached figure

we know that
total amount of sap =[3*(1/4)+2*(3/8)+4*(5/8)+1*(1)]
total amount of sap =[(3/4)+(6/8)+(20/8)+(1)]
total amount of sap =[(3/4)+(3/4)+(10/4)+(4/4)]
total amount of sap =[20/4]
total amount of sap =5 gallons
total of trees=10

<span>[amount of sap collected from each tree]=total amount of sap/total of trees
</span>
[amount of sap collected from each tree]=5/10----> 0.5 gallons per tree

the answer is
0.5 gallons
