Answer: hello your question was poorly written but i was able to the get missing parts online which enabled me resolve your question

answer:

a) a = 0.1096

b) 1.89 watts

Step-by-step explanation:

Std of output voltage = 0.25 volt

H0 : μ = 5 volts

Ha : μ ≠ 5 volts

n = 16

a) Acceptance region = 4.9 ≤ X ≤ 5.1

Determine the value of a

value of a = 0.0548 + 0.0548

= 0.1096

<em>attached below is the reaming solution</em>

note : a is a type 1 error

b) power of test

True mean output voltage = 5.1 volts

P = - 1.89 watts

power cant be negative hence the power of the test = 1.89 watts

A recipe for orange water says, “Mix 3 teaspoons of yellow water with 1 teaspoon red water.” For this recipe, we might say: “The

Hunter-Best [27]

Well, we know that 3:1 is one batch of orange water. We also know that there are 2 things to focus on.

1. Must write ratio for 2 batches of the recipe.

2. Must write ratio for 4 batches of the recipe.

To make this equation simple, double the ratio to find 2 batches because all it means is 2x more water.

3:1

6:2

So, the ratio would be 6:2 to make 2 batches.

To make it easier again, we just multiply the ratio of 2 batches by 2 which would find the ratio for 4 batches.

6:2

12:4

So that means, that it is 6:2 for 2 batches, and 12:4 for four batches.

Using matrix algebra, the material cost of making one of each product at each location is as follows:

Product X Product Z

Location A birr 38 birr 50

Location B birr 38 birr 49.5

<h3>What is matrix algebra?</h3>

Matrix algebra involves the arrangement of numbers in a rectangular array.

Matrices are arranged in columns and rows to express some mathematical values.

<h3>Data and Calculations:</h3><h3>Matrix O: Materials Requirement Per Unit</h3>

Steel Glass Plastic

Product X 3 1 2

Product Z 4 0.5 3

<h3>Matrix P: Materials Cost Per Unit</h3>

Steel Glass Plastic

Location A 10 2 3

Location B 9 3 4

<h3>Matrix R: (O x P) Material Cost of Product X</h3>

Steel Glass Plastic Total

Location A 30 2 6 38

Location B 27 3 8 38

<h3>Matrix R: (O x P) Material Cost of Product Z</h3>

Steel Glass Plastic Total

Location A 40 1 9 50

Location B 36 1.5 12 49.5

Thus, Product X costs birr 38 at locations A and B, respectively, while Product Z costs birr 50 and birr 49.5 at locations A and B, respectively.
