Which number produces an irrational number when added to 0.4

1 answer:

6 0

Any other irrational number. 0.4 is rational (ie., it can be written as a fraction), but rational+irrational is always irrational.

So examples would be π or √2. If you add those, the result is irrational.

List the sample space for rolling two dice and finding the sum of the numbers. How many 8's are there in the sample space? [Assu

Reptile [31]

Using the given assumption, there are 3.

The sample space for rolling two dice and finding the sum is:

2 3 4 5 6 7
3 4 5 6 7 8
4 5 6 7 8 9
5 6 7 8 9 10
6 7 8 9 10 11
7 8 9 10 11 12

From the sample space alone, there are 5. However, since a 3 and a 5 is the same as a 5 and a 3, this means that 2, 6 is the same as 6, 2 as well; this takes 2 off of the 5, leaving us 3.

the population of arizona is estimated go increase by 6.2% every year. if the population was 4.18 million in 2016 estimate popul

aleksklad [387]

Given:

a.) The population of Arizona is estimated to increase by 6.2% every year.

b.) The population was 4.18 million in 2016.

For us to be able to determine the population in 2022, we will be using the following formula:

$\text{ P = P}_0e^{rt}$

Where,

P = Total population after time (t)

P₀ = Starting population = 4.18 million

r = Growth rate (in decimal form) = 6.2%/100 = 0.062

t = time (in years) = 2022 - 2016 = 6 years

e = Euler's number = 2.71828182845

We get,

$\text{ P = P}_0e^{rt}\text{ = (4,180,000)(}2.71828182845)^{0.062(6)}$ $\text{ P = 6,063,645.861797897 }\approx\text{ 6,063,646}$

Therefore, the population in 2022 will be approximately 6,063,646.
