Answer:
4 years
Explanation:
Let x be the age ( in years ) of each daughters,
∵ Mother is 30 years older than her daughters,
⇒ Age of the mother = x + 30
Now, after 2 years,
The age of each daughter = x + 2,
And, the age of the mother = x + 30 + 2 = ( x + 32 ) years,
According to the question,
3(x+2+x+2) = x + 32
3(2x+4) = x + 32
6x + 12 = x + 32
5x = 20
⇒ x = 4
Hence, each of the daughters is 4 years old.
Answer:
Random Sampling
Explanation:
According to my research on different research methodology, I can say that based on the information provided within the question Ariana is ensuring that her survey results are accurate by using Random Sampling. This is a survey method in which participants are chosen at random. This ensures that results are accurate because it gets rid of any researcher bias that may occur if the participants were specifically chosen.
