Answer:

Both angles x and y are 69 degrees

Step-by-step explanation:

Because the angle with measure 69 degrees and angle x are alternate interior angles, they have equal value. Therefore, x has measure 69 degrees. Because this figure is a trapezoid, angle y is supplementary to the angle with measure 111 degrees. Therefore, y=180-111=69 degrees as well. Hope this helps!

A public health department wants to determine the rate that parents of teen boys are choosing to vaccinate their sons for HPV wi
viktelen [127]

Answer:

The correct option is  B

Step-by-step explanation:

From the question we are told that

   The  sample size is  n  =  64

    The  proportion that choose to vaccinate the teen boys is  \r p =  0.12

considering the first statement

The 95% confidence interval is 12% ± the margin of error*standard deviation is  false because

The 95% confidence interval is is  %12 ± the margin of error

considering the second statement

The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem

   np =  64 * 0.12 =  7.68

and this value is  less than 10  hence the confidence interval should not be calculated

considering the third statement

A 99% confidence interval will be smaller than the 90% confidence interval is false

  This is because as the confidence level increase (for example  from 90% to  99%) the margin of error increase which increases the confidence interval

If the area of a circle is 58 square feet, find the circumference. A. 22.35 ft. B. 26.99 ft. C. 4.25 ft. D. 42.5 ft.
Fed [463]

Answer:

  B.  26.99 ft.

Step-by-step explanation:

The formulas for circumference (C) and area (A) are ...

  A = πr²

  C = 2πr

Solving the area formula for r, we get ...

  r = √(A/π)

Substituting this into the circumference formula gives ...

  C = 2π√(A/π) = 2√(πA)

For the given circle, the numbers are ...

  C = 2√(3.14×58 ft²) ≈ 26.99 ft
