She made her mistake at the first step. To simplify a radical, you would find two numbers that multiply by each other to get your original number (under the radical)
and have one of the number be a perfect square.
Her reasoning is wrong because 10*10 is not
. Had she been correct, her answer should have been able to be squared to equal
In other words, she should have done
(We used 25 because 25 is a perfect square, 5*5=25).

Answer:
The Answer is :
Decrease of price in dollars is 4,225
Next model price is 37000-4225
Ans:- 32,775
429/36
Try and round the values...
430/40
Better?
That's about 10... 10 3/4.
429/36 is about 12 though.
Try and see which number is closest in your list.

Answer: Choice A) 0.20</h3>
===================================================
Explanation:
Let's say there are 1000 students. The students must take math, science or they can take both simultaneously.
- 65% of them are in math. So there are 0.65*1000 = 650 math students.
- 43% are in science, leading to 0.43*1000 = 430 science students.
- 13% are in both so we have 0.13*1000 = 130 students who are in both.
Now onto the sentence that says "Suppose a high school student who is enrolled in a math class is selected at random"
This means we only focus on the 650 math students and ignore the 1000-650 = 350 students who aren't in math.
Of those 650 math students, 130 are also in science (since 130 are in both classes).
The probability we're after is therefore 130/650 = 0.20
