A contract between a manufacturer and a consumer of light bulbs specifies that the mean lifetime of the bulbs must be at least 1
Alex17521 [72]

Answer:

Follows are the solution to the given points:

Step-by-step explanation:

In point a:

In this sense, describe what type of error I will be.

Type I error: to conclude that perhaps the mean bulb life would be less than three hours when it becomes (at least) 3 hours.

In point b:

Describe throughout this context what the Type II error becomes.

An error of type II: never assuming that its bulbs' mean lifetime is much less than 3 hours. three hours at least

In point c:

What error — type I and type II — would further impact the interaction between the manufacturer and the customer?

A Type II error is probably further problematic because it means that even the buyer will buy bulbs that do not last long.

What is the y-intercept of the function, represented by the table of values below
Basile [38]

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope- formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 2, 15) and (x₂, y₂ ) = (1, 6) ← 2 ordered pairs from the table

m = \frac{6-15}{1-(-2)} = \frac{-9}{1+2} = \frac{-9}{3} = - 3 , then

y = - 3x + c ← is the partial equation

To find c substitute any ordered pair from the table into the partial equation

Using (2, - 3 ) , then

- 3 = - 6 + c ⇒ c = - 3 + 6 = 3

The y- intercept c = 3 → D

Please answer the question in the picture above
Andreas93 [3]
The difference between the masses is
  4.55·10¹³ kg -1.78·10¹² kg
  = 4.55·10¹³ kg - 0.178·10¹³ kg
  = (4.55 -0.178)·10¹³ kg
  = 4.372·10¹³ kg

Rounded to the appropriate precision, the mass of the Antarctic iceberg exceeds that of the Rock of Gibraltar by ...
  4.37·10¹³ kg

The base of a right rectangular prism has an area of 84.6 square centimeters and a height of 7 centimeters. What is the volume,
AlladinOne [14]

Answer:

The volume of the right rectangular prism is  592.2cm³

Step-by-step explanation:

To calculate the volume of a rectangular prism we have to multiply the area of ​​the base by the height

a = area of the base = 84.6cm²

h = height = 7cm

v = volume

v = a * h

v = 84.6cm² * 7cm

v = 592.2cm³

The volume of the right rectangular prism is  592.2cm³
