Answer:

Hi, There! Mika-Chan I'm here to help! :)

<u><em>To find the distance from a point to a line, first find the perpendicular line passing through the point. Then using the Pythagorean theorem, find the distance from the original point to the point of intersection between the two lines.</em></u>

I got 110 because 35+35=70 and 180-70=110. I added 35 to 35 because it says that AB=AD, so they should make congruent angles. So add the 35+35 and work from there.

To create a confidence interval from a bootstrap distribution using percentiles, we keep the middle values and chop off a certai
Nataliya [291]

Answer:

a

 \frac{\alpha }{2}  =  2.5 \%

b

  N  = 25

Step-by-step explanation:

From the question we are told that

   The number of bootstrap samples is  n =  1000

From the question we are told the confidence level is  95% , hence the level of significance is    

      \alpha = (100 - 95 ) \%

=>   \alpha = 0.05

Generally the percentage of values that must be chopped off from each tail  for a 95% confidence interval is mathematically evaluated as

      \frac{\alpha }{2}  =  \frac{0.05}{2}  =  0.025 = 2.5 \%

=>    \frac{\alpha }{2}  =  2.5 \%

Generally the number of the bootstrap sample that must be chopped off to produce a 95% confidence interval is

      N  =  1000 *  \frac{\alpha }{2}

=>   N  =  1000 *  0.025

=>   N  = 25
