Answer:

A 90 percent level can be obtained with a smaller sample, which usually translates into a less expensive survey. To obtain a 3 percent margin of error at a 90 percent level of confidence requires a sample size of about 750. For a 95 percent level of confidence, the sample size would be about 1,000.

Answer:

The bottle of juice is $1

Step-by-step explanation:

It is one dollar because if you break down the fact that if you get an apple and a bottle of juice and you have to pay $3 then it's fairly easy to figure out that the only solution is that the apples cost $2 each so if you get three apples and one juice then you subtract 6 from 7 and you get $1

The length of the rectangle is twice its width. Write and solve a system of linear equations to find the length L and width W of
nignag [31]

Answer:

The length is equal to 12 and the width is equal to 6.

Step-by-step explanation:

In order to find the values here, we start by setting the width equal to x. Now knowing this, we know that the length is twice that long. Therefore, the length would be equal to 2x. Now we can use the perimeter formula to solve the equation.

2L + 2W = P

2(2x) + 2(x) = P

4x + 2x = 36

6x = 36

x = 6

Now with the given value for x, we can tell that the width is 6 and then we multiply it by 2 to get the length value (12).
