Simplify the equation


√363 becomes 11 √3

3 √27 becomes 9 √3

11 √3 - 9 √3 = 2 √3

Explanation: Find the factors of each number

363 factors are 33, and 11

Find which one you can take the square root from which is 33 and that is how you get 11 √3

3 √27 can be simplified more because the factors of 27 are 9, 3 take the square root of 9. And multiply the leftover 3 with the outside number which is also 3. Then you get 9 √3

Now just subtract

11 √3 - 9 √3

= 2 √3

Sorry if this is confusing but I hope it helps !!

Suppose the true proportion of voters in the county who support a restaurant tax is 0.5. Consider the sampling distribution for
Ahat [919]

Answer:

the mean of the sampling distribution for the proportion of supporters with sample size n = 165 is 0.5.

Step-by-step explanation:

According to the Central Limit Theorem, assuming the sampling is random and sample size is big enough (≥30) the mean of the sampling distribution is the population mean.

Therefore the mean of the sampling distribution for the proportion of supporters with sample size n = 165 is 0.5

The coordinates of three vertices of square ABCD are A(−212,112),B(−212,−3), and C(2,112).
Lady_Fox [76]

Answer:

<em>P=760</em>

Step-by-step explanation:

Three of the coordinates of the square ABCD are A(-212,112) B(-212,-3) C(2,112). The image below shows the square is not ABCD but ABDC. In fact, this is not a square, as we'll prove later.

Note the x-coordinate of A and B are the same. It means this side is parallel to the y-axis. Also, the y-coordinate of A and C are the same, meaning this side is parallel to the x-axis. The missing point D should have the same x-coordinate as C and y-coordinate as B, i.e. D=(2,-3).

This shape has sides that are parallel to both axes.

To calculate the perimeter we find the length of two sides.

The distance from A to B is the difference between their y-axis:

w=112-(-3)=115

The distance from A to C is the difference between their x-axis:

l=2-(-212)=215

It's evident this is not a square but a rectangle. The perimeter is

P=2w+2l=330+430

P=760
