Answers

Answer 1
Answer:

Answer:

employees of large corporation

Step-by-step explanation:

the sample was 500 but they are simply a representation of the population, being the all the people who are part of the company and receive emails.

Answer 2
Answer: Population: The entire set of emails sent to the large corporation.

Sample: The 500 randomly chosen emails used for the analysis.

Sample Percentage of Spam: 76.4%

Hypothesis Test: The system manager is testing whether the actual percentage of spam in the entire population of emails sent to the corporation is 80%.

Based on the provided information, it seems that the system manager conducted a sample analysis to compare the observed sample percentage of spam (76.4%) to the hypothesized population percentage (80%). The next steps would involve performing a statistical hypothesis test, such as a one-sample proportion test, to determine if the observed difference is statistically significant or if it could have occurred due to random chance.

HELP PLEASEEE!!! BRAINLIEST!!!Which expression correctly shows 20x^4−25x^3+60x^2−75x factored completely over the integers?

(x^2+3)(4x−5)
5x^2(x+4)(3x−5)
5x(x^2+3)(4x−5)
5x(x^2−3)(4x+5)

Answers

The expression correctly shows 20x⁴-25x³+60x²-75x will be 5x(x²+3)(4x-5).Option C is correct.

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that,

The expression is,

=20x⁴-25x³+60x²-75x

Take 5x³ from the first two terms and 15x from the third and fourth terms as

=20x⁴-25x³+60x²-75x

=5x³(4x-5) + 15x(4x-5)

=(5x³+15x)(4x-5)

Thus, the expression correctly shows 20x⁴-25x³+60x²-75x will be 5x(x²+3)(4x-5). Option C is correct.

How many inch cubes can fit into an empty box with a volume of 2 cubic feet?

Answers

Even though it's 2 cubic feet, it doesn't matter. It still can be transformed into inches. 

1 foot = 12 inches

Multiply the 2 feet by 12 which should be:
12×2=24

So 24 cubic inches can be fit into a empty box with a volume of 2 cubic feet.
Hope this helps!
1 feet= 12 inches
2 feet= 12 times 2 = 24 inches

24 inch cube can fit into an empty box with the volume of 2 cubic feet
