Answer:

The correct option is a)

05; .73; .27 , type 1 error, type 11 error and the power of the test respectively.

Step-by-step explanation:

Alpha is the probability of a type 1 error, given the null hypothesis is true. Therefore alpha= 0.05

Type 11 error is the probability of accepting a false null hypothesis.

Beta= 0.73

The Power of a test is the probability of rejecting the null hypothesis, given it is false

Power= 1- beta

Power= 1-0.73

Power= 0.27

Therefore the type 1 error is 0.05

The type 11 error is= 0.73

The power of the test= 0.27

The right option is a)

(4y − 3)(2y2 + 3y − 5)
VladimirAG [237]

Answer:

8y^3+6y^2-29y+15

Step-by-step explanation:

the correct expression is

(4y − 3)(2y^2 + 3y − 5)

Given data

We have the expression

(4y − 3)(2y^2 + 3y − 5)

let us open bracket

8y^3+12y^2-20y-6y^2-9y+15

Collect like terms

8y^3+12y^2-6y^2-20y-9y+15

8y^3+6y^2-29y+15

Find the missing side of the triangle. leave your answer in simplest radical form
KIM [24]

missing side is x} = 10.15 mi .

<u>Step-by-step explanation:</u>

Here we have the following info from the figure: A right angled triangle with following dimensions

Perpendicular = x

base = \sqrt{122}

Hypotenuse = 15

By Pythagoras Theorem :

Hypotenuse^2 = Perpendicular^2 + base^2

⇒ Hypotenuse^2 = Perpendicular^2 + base^2

⇒ 15^2 = x^2 + (\sqrt{122})^2

⇒ 225 = x^2 + 122

⇒ x^2 = 225-122

⇒ x^2 = 103

⇒ (x^2)^\frac{1}{2} = (103)^\frac{1}{2}

⇒ x} = (103)^\frac{1}{2}

⇒ x} = 10.15

Therefore, missing side is x} = 10.15 mi .
