Answer:
Counselor's estimate isn't correct.
Step-by-step explanation:
Total number of students in university = 30,600
2% break 3 of the languages
Therefore, 2/100 × 30600 = 612 students break 3 of the languages in the University according to the counselor.
In a random sample of 240 students, 20 break 3 of the languages.
% = 20/240 × 100 = 8.33%
SinceTotal number of students = 30,600
Therefore, 30,600/240 = 127.5
Which means 127.5 × 20 = 2550.
Which means 2550 students break 3 of the languages as against the 612 students stated by the counselor.

Answer:
No, they are not the same.
Step-by-step explanation:
Lets say the price is 100 dollars. Lets start with the 25 and then 10 percent off. Since its 25% off we need to multiple the 100 dollar price by .75.
100*.75=75
Now that we have the 75 dollar price, we need to take off the 10%. We need to multiply the current price of 75 by .9
75*.9=67.5
The price after these 2 discounts is $67.50
Now lets do the 35% off right away. Since is 35% off we need to multiple our right of 100 by .65.
100*.65=65
The price after the 35% off is $65
So no, they are not the same.
