Find the perimeter and round to the nearest tenth
tekilochka [14]

Answer:

Perimeter = 12.0 m

Step-by-step explanation:

Perimeter = AB + AC + BC

AB = 5 m

B = 53°

Use trigonometric functions to find AC and BC respectively.

✔️Find AC:

Reference angle = 53°

Opposite side length = AC

Hypotenuse = 5 m

Apply SOH, which is:

Sin 53 = Opp/Hyp

Sin 53 = AC/5

5*Sin 53 = AC

AC = 3.99317755 ≈ 4 m

✔️Find BC:

Reference Angle = 53

Hypotenuse = 5 m

Adjacent = BC

Apply CAH, which is:

Cos 53 = Adj/Hyp

Cos 53 = BC/5

5*Cos 53 = BC

BC = 3.00907512 ≈ 3.0 m

✔️Perimeter = 5 + 4 + 3 = 12.0 m

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
