Identify the number as rational or irrational. Explain
-√127

Answers

Solve:-

-√127 = ?
-√127 = -11.2694276695846449

The answer to this is irrational because this number goes on and on forever and it can not be expressed as a ratio, so your answer is irrational.

Hope I helped ya!! xD

Its irrational because the square root of 127 is a decimal that goes on and on and cannot be represented as a fraction. So it is irrational.
Hope this helps.

The original value of a car is $18,000, and it depreciates (loses value) by 15% each year. what is the value of the car after three years?

Answers

If the original value of a car is $18,000, and it loses value by 15% each year, then you can calculate the new value of the car after n years using following formula:

$P=\$18,000\cdot (1-0.15)^n.$

When n=3, then

$P=\$18,000\cdot (1-0.15)^3=\$18,000\cdot 0.85^3=\$11,054.25.$

Answer: the value of the car after 3 years is $11,054.25.

I think the answer would be 11,054.25$

f the probability of being hospitalized during a year is 0.25 , find the probability that no one in a family of five will be hospitalized in a year.

Answers

Answer:

The probability that no one in a family of five will be hospitalized in a year is 0,2373

Step-by-step explanation:

Let p denote the probability of being hospitalized during a year,

Then p=0.25

And p' the probability of not being hospitalized during a year is 1-p

Thus p' = 1-p = 1-0.25 = 0.75

The probability that no one in a family of five will be hospitalized in a year is equal to $p'^(5)$ . That is

$p'^(5)$ = $0.75^(5)$ ≈ 0,2373
