The first question is a Statistical Question. This is because Statistical Questions are questions that can be answered with a percent, range or average. It could have many correct answers.

The Second one is a Non-Statistical Question. This is because this cannot be answered with a percent, range, or average.

Shania and Pedro are discussing whether it is always possible to solve a right triangle, given enough information, without using
Makovka662 [10]

Answer: Shania is correct.

Step-by-step explanation:

For a right angled triangle, given two sides and an angle, we can use the sine rule or the various trigonometry identities to solve the triangle;

a/sin A = b/sinB

and

sin (angle) = opposite side/hypotenuse

cos (angle) = adjacent side/hypotenuse

tan (angle) = opposite/ adjacent

assuming a is the opposite side of angle A and b is also opposite of angle B

Otherwise, the only way to solve a triangle given two sides only is by the use of the Pythagoras theorem.

Hence, Shania is correct.

The Institute of Education Sciences measures the high school dropout rate as the percentage of 16- through 24-year-olds who are
USPshnik [31]

The appropriate hypothesis which is used to test the dropout rate are H_{0}:p > =0.081\\ and H_{1}: p < 0.081.

Given Drop out rate through 24 year old who are not enrolled is 8.1%, sample size=1000 and we have to find the hypothesis to test the drop out rate of the school.

The variable which needs to be studied is X=Number of individuals with age between 16 and 24 years old that are high school dropouts.

The parameter of interest is the proportion to high school drop outs is p.

Sample proportion=p^{1}=0.065

The hypothesis can be formed as under:

H_{0}:p > =0.081  (null hypothesis)

H_{1}:p < 0.081      ( alternate hypothesis)

Null hypothesis is a hypothesis which is tested for its validity and alternate hypothesis is hypothesis which is opposite of null hypothesis means if null hypothesis is rejected then the alternate hypothesis will be true.

Z_{H_{0} }=(p^{1}-p)/\sqrt{p*(1-p)/n}

=0.065-0.081/\sqrt{(0.081*0.0919)/1000}

=-1.85

Hence the appropriate hypothesis  are H_{0}:p > =0.081 and H_{1}:p < 0.081.

This figure is made up of a triangle and a semicircle.
Mila [183]
Area of triangle = 1/2 (8)(4) = 16
Area of semi-circle = 1/2 (3.14)(4^2) = 1/2(3.14)(16) = 25.12

Area of figure = 16 + 25.12 = 41.12

answer
41.12 square units
