Answer:

The correct answer to the following question will be "60 students".

Step-by-step explanation:

Marta will be taking a sampling frame from some kind of 600 student group.

Mean,

N = 60  

Although the sampling method could perhaps consist of the following components 10% of the population,

⇒  600\times 10 \ percent

⇒  60

In order to view these findings as autonomous, 60 students would then have to analyze Marta lacking replacements.

sladkih [1.3K]

Answer:

Here is a proof

 

Angle DEF  =  angle ABC              

A transversal cutting two parallel lines makes alternate exterior angles equal

 

Sum of  measures of angles 1 and 2  = 50° + 48°  =  98°   = measure of angle DEF  =  measure of angle ABC

 

But since  s bisects   angle ABC, then angle 4  =  98 / 2   = 49°

 

But angles 3 and 4  are vertical angles....therefore.... measure of angle 3  =  49°

Function,d(r) = 0.034r , is used to convert Russian rubles in United States dollars, and function, e(d) = 0.76d , is used to con
Dahasolnce [82]
We have two functions, one which converts rubles to USD and one which converts USD to euros. If we want to convert from rubles to euros, we could just convert it to USD and then euroes.

2000₽ ⇒ USD
d(r)=0.034r\\d(2000)=0.034(2000)=68

$68 USD ⇒ €
e(d)=0.76d\\e(68)=0.76(68)=\boxed{51.68}

Extra: If you wanted, you could create a function to convert rubles into euroes.
Just substitute that 0.034r for d in e(d) = 0.76d and...e(r)=0.76(0.034r)=0.02584r
