Use the given information to find the lengths of the other two sides of the right triangle if side a is opposite angle A, side b

is opposite angle B, and side c is the hypotenuse.
tan(A) = 7/9, b = 4

I already found (a) which is 28/9, I just need to find c =

c = \frac{4\sqrt{30} }{9}

using Pythagoras' identity on the right triangle

c = √( 4² + (\frac{28}{9} )² ) = √16 + \frac{2080}{81}

 = \frac{\sqrt{2080} }{9} = \frac{4\sqrt{130} }{9}

Answer:

Type I: 1.9%, Type II: 1.6%

Step-by-step explanation:

given null hypothesis

H0=the individual has not taken steroids.

type 1 error-falsely rejecting the null hypothesis

⇒   actually the null hypothesis is true⇒the individual has not taken steroids.

 but we rejected it ⇒our prediction is the individual has taken steroids.

typr II error- not rejecting null hypothesis when it has to be rejected

⇒actually null hypothesis is false ⇒the individual has taken steroids.

but we didnt reject⇒the individual has not taken steroids.

let us denote

the individual has taken steroids by 1

the individual has not  taken steroids.by 0

                            predicted

                              1       0

   actual          1    98.4%  1.6%

                        0   1.9%   98.1%

so for type 1 error  

 actual-0

predicted-1

therefore from above table we can see that probability of Type I error is 1.9%=0.019

so for type II error

   actual-1

predicted-0

therefore from above table we can see that probability of Type I error is 1.6%=0.016

How many 12 x 12 pavers for 600 square feet?
34kurt
First, we calculate the area of one paver. This is:
12 x 12 = 144 square feet
Now, the number of pavers required may be determined by dividing the total surface area to be covered by the surface area of one paver, as:
number of pavers = 600 / 144
Number of pavers = 4.2

Because 0.2 pavers can not be obtained, 5 pavers are needed to completely cover 600 square feet.
