Answer: 0.31
Step-by-step explanation:
Let A denotes the event that the students report drinking alcohol and B denotes the students report using some type of tobacco product .
Given : P(A) =0.84 ; P(B)=0.33 and P(A∪B)=0.86
We know that 
Then, the probability that the student both drunk alcohol and used tobacco in the past month is given by :-
Hence, the probability that the student both drunk alcohol and used tobacco in the past month = 0.31
Answer:
355 bushels.
Step-by-step explanation:
To know the amount of wheat the truck hauls each trip, we need to divide the total amount of bushels of wheat between the total of trips of the truck.
The total amount of bushels is 4970 and the total of trips is 14.
Then, the amount of bushels for each trip would be 4970/14 = 355.
Therefore, the truck hauls 355 bushels of wheat each trip.
πr² = π.5.5 = π25 units² or 78.5 units²

$60. You change 25% to the decimal of .25 and multiply it by $240 to see what 25% of $240 is.
Answer:correct answer =0
Step-by-step explanation:
Step 1
5x - (x + 3)2
Putting the coefficient of x =2 in the equaton we have
5(2) - (2 + 3)2
Solving out
5(2) - (5)2
= 10- 10
=0
Step 2
Amir's mistake was in the multiplication and wrong use of the negative sign of the bolded below
5(2) - (2 + 3)2 = 10 + (-5)2 = 10 + 25 = 35
-(5)2 cannot give 25 instead 10, so him getting a 25 and wrong use of the negative and positive made his answer wrong.
The right answer as calculated in step 1 = 0
