Remark
Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.
Solution.
The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.
When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.
When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.
So the answer is C <<<<< Answer.
When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.
Answer:
The correct option is;
e. 2500
Step-by-step explanation:
The formula for sample size is given by the following formula;
At 95%, z = 1.96
ε = Margin of error = 0.02 = 2%
Finding the sample size, n, given only the margin of error is by the following formula;
Margin of error = 100/√n
Therefore, we have;
2 = 100/√n
√n = 100/2 = 50
n = 50² = 2500
Therefore, the correct option is e. 2500.
Answer:
13/4 + 5/8
Step-by-step explanation:
Change the mixed number into a fraction and change the integer of -(-) to equal + because two negatives equal a positive
