Answer:
We can break this down:
The student has a one out of five chance of getting a correct answer, and a four out of five chance of an incorrect answer. We can express the students odds of getting one incorrect answer as 4/5. In order to get the odds of two wrong answers, we need to multiply this answer again by the odds of choosing a wrong answer. Therefore:
The odds of one wrong answer = 4/5
The odds of two wrong answers = (4/5) * (4/5) = 16/25 chance of getting both of the questions wrong.
Step-by-step explanation:
Answer:
He has 7 days
Step-by-step explanation:
He consumes 1/8 cups of berries per day, 1/8=1 day
He has 7/8 cups of berries
To get the number of days it takes for 7/8 cups
Number of days=(Number of cups of berries he has)/(The number of berries he consumes in a day)
(7/8)÷(1/8)=(7/8)×8=7 days
The perimeter of a rectangle is given by the formula,

We substitute,
and

into the above formula to obtain the expression,


We now group the x and y terms on the Left Hand Side of the equation to get.


We now divide through by 2 to get,

Therefore the width of the rectangle is

Well the sum is 15+6=21. then you must do 81-21=60. So your answer must be t=60.
