We are asked to solve for the angle of rotational symmetry of a given regular polygon and the formula is degrees of rotation = 360° / number of sides. In this problem, the solution is shown below:
We used n = 5 since pentagon has five number of sides
degrees of rotation = 360° / 5
degrees of rotation = 72°

The answer is the third in the choices 72°.

What is the equation of a line that is perpendicular to y = 3 x − 2 and passes through the point ( 6 , 8 ) Was

Hello!

To find the line that is perpendicular to y = 3x - 2 and passes through the ordered pair (6, 8), we will:

Find the negative reciprocal using the slope of the given function
Substitute the given ordered pair into the new equation with the slope found in step 1

Let's remind ourselves of slope-intercept formula. Slope-intercept formula is y = mx + b, where m is the slope, and b is the y-intercept.

In the given equation, we know that 3 is slope. With that, we can find the negative reciprocal of that slope, and continue to step #2.

To find the reciprocal, we will need to flip our fraction. In this case, 3/1 = 3, so once we flip it, it is 1/3. Since it is the negative reciprocal, the fraction is a negative, so the negative reciprocal is -1/3.

Now, we will substitute the ordered pair into the slope-intercept formula with our new slope.

y = -1/3x + b (6, 8)

8 = -1/3(6) + b

8 = -2 + b (add 2 to both sides)

10 = b

Therefore, the equation of the line is y = -1/3x + 10.

For the data set below, calculate the standard deviation to the nearest hundredth decimal place. 27 38 47 42 33 56 37 57 38 52

In order to calculate standard deviation, apply the standard deviation formula, which is given in the attached file. In this formula, we are finding the square root of the sum of the square of given values less their mean value (the sum of the given numbers divided to their amount) divided to N-1, where N is the amount of the given numbers. When we calculate the mean, it is 42.7 and the standard deviation is 10.02275
