Answer:
gallons of ice tea is left with Morris
Step-by-step explanation:
Morris has 2 3/4 gallons of ice tea. He gives 3/7 of it to her friend.
Morris has 2 3/4 gallons of ice tea
He gives 3/7 of it to her friend.
To find how many gallons of ice tea does Morris have left , we subtract 3/7 from 11/4
Make the denominators same
The value of x is 1.25 or 1 1/4
Explanation
==============================
275x=500-125x
Move variable to the left side and change its sign
275x+125x=500
Collect the like terms
275x+125x=500 =====> 400x=500
Divide both sides of the equation by 400
400x/400=500 =======> x=5/4 which is the same as 1 1/4 or 1.25
Hope this helps : )
Answer:
The Possible model is binomial distribution model.
Step-by-step explanation:
The argument that both students cheated in the exam can be proved by a hypothesis that both the students got the same answers incorrectly.
The same incorrect answers prove that both students have cheated on the test.
Therefore the sample of incorrect answers is, n = 8
Thus, the success probability, P = 0.25
Since the given condition has only two outcomes that are choosing the same answer or not choosing the same answer. Thus, this can be solved by the binomial distribution model.
So, binomial distribution with n = 8 and p = 0 .25.
I would guess it would be
7 and -7
