Answer:

0.022

Step-by-step explanation:

Given that :

Population size = 25000

n = 500 ; p = 0.4

Size of random sample (n) = 500

5% of population size : 0.05 * 25000 = 1250

Distribution is normally distributed since n < 5% of population size

Hence, the mean of the distribution = p = 0.4

Standard deviation = √((pq) /n)

q = 1 - p ; q = 1 - 0. 4 = 0.6

Standard deviation = √((0.4 * 0.6) /500)

Standard deviation = 0.0219089

= 0.022

leva [86]

Answer:

-36x² - 8x - 8

Step-by-step explanation:

Distribute 6x and -8 through the parenthesis:

-48x + -36x² - 8 + 40x

Collect the like terms:

-8x - 36x² - 8

Use the commutative property to reorder the terms:

-36x² - 8x - 8

If the US released 5.877 billion metric tons of carbon dioxide and 1 trillion pounds=0.4536 billion metric tons, how many trilli
Nikolay [14]

Answer: 12.96 trillion pounds

Step-by-step explanation:

From the question, we are informed that:

1 trillion pounds = 0.4536 billion metric tons

Therefore, if the US released 5.877 billion metric tons of carbon dioxide, the trillions of pounds of carbon dioxide that the US release will be:

= 5.877 / 0.4536

= 12.96 trillion pounds

The chocolate Shoppe has a rectangular logo for their business that measures 2 1/2 feet tall with an area that is exactly the ma
Ilya [14]

The equation that could be used to determine L, the unknown side length of the logo is A =2.5w

<h3>How to determine the equation?</h3>

The given parameters in the question are:

  • Shape: Rectangle
  • Height of logo, h = 2 1/2 feet

From the question we understand that the area is at maximum.

Represent this area with A

The area of the rectangle is:

A = h * l

Where h and l are the dimensions of the rectangle.

Substitute 2 1/2 for h

A = 2 1/2 * l

Express 2 1/2 as a decimal number

A = 2.5 * l

Evaluate the product

A =2.5l

Hence, the equation that could be used to determine L, the unknown side length of the logo is A =2.5w
