Answer:

between 45% and 51%

Step-by-step explanation:

Data provided:

Margin of error = plus or minus 3%

Confidence level = 95%

Number of voters asked = 1,000

Respondents considered  themselves independent = 48%

Now,

adjusting the margin of error in the result

we get

the range as:

lowest value of range percentage of independents among voters in Maine

= 48% - 3%

= 45%

and,

Highest value of range percentage of independents among voters in Maine

= 48% + 3%

= 51%

Hence,

the percentage of independents among voters in Maine are between 45% and 51%

Please help me... the perimeter of square WXYZ is 20 units. The coordinates of three of the vertices are W(3,2), X(3,7), and Y(8
Blababa [14]
Okay, so we know that the perimeter of the square is 20. Since a square has 4 equal sides to find the length of one side, 20/4. Each side is equal to five. Look at each of the coordinates and put them respectively into a graph in your mind. w(3,2) (bottom left) x(3,7) (top left) Y(8,7) (top right). Now we know we need to find the bottom right coordinate. Being that both of the coordinates on the left have the same x value we can justify that the coordinates on the right have the same X value also. we can say this same thing for the y coordinate. Since both coordinates on the top of the square have the same Y value, we can justify that the coordinates on the bottom have the same Y value. So taking the coordinates we now are the same, the answer is Z(8,2). We can check his by seeing if the distance if five from each of the adjacent coordinates. If you have any questions comment below.

Triangle A B C is shown. Side A C has a length of 27. Side C B has a length of 54.
Natali5045456 [20]

The possible length of segment AB is 27 < AB < 81

From the question, we have

In triangle ABC

AC = 27

CB = 54

Using Pythagoras theorem,

AC² = AB² + CB²

54² = AB² + 27²

AB = 47

The possible length of segment AB is 27 < AB < 81

Multiplication:

To determine the sum of two or more numbers, mathematicians multiply the numbers. It is a basic mathematical procedure that is widely used in daily life. Multiplication is used when we need to mix groups of like sizes. Multiplication is a representation of the underlying idea of adding the same number repeatedly. The outcome of multiplying two or more numbers is referred to as the product of those numbers, and the factors are the quantities that are multiplied. Multiplying the numbers makes it simpler to add the same number repeatedly.
