Convert 11.42424242 to a rational expression in the form of a/b , where b ≠ 0.

TiliK225 [7]

11.424242
isolate the repeating part
11+0.424242

focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242

subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99
$x=\frac{42}{99}$

so
$11.\overline{42}=11 \space\ \frac{42}{99}$

What are the explicit equation and domain for an arithmetic sequence with a first term of 8 and a second term of 5?

boyakko [2]

Answer:

Option C.

Step-by-step explanation:

It is given that the first term of the arithmetic sequence is 8 and second term is 5.

$a=8$

$d=5-8=-3$

We know that the explicit equation of an AP is

$a_n=a+(n-1)d$ , where n is an integer greater than or equal to 1.

where, a is first term and d is common difference.

$a_n=8+(n-1)(-3)$

$a_n=8-3(n-1)$

So, domain of this explicit equation is all integers where n ≥ 1.

Therefore, the correct option is C.

If the probability of getting a particular result in an experiment is 75.3%, what is the probability of not getting that result?

goldfiish [28.3K]

Well the probabilities of one or more different outcomes have to add up to 100%. You can't have one outcome be 90% and another be 20% because it does not equal 100%.
So if you know the percentage of one outcome you have to subtract that from 100%
That means C is your answer.
