<h3>
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
Answer: I think it is -x/8+2y/3+10
Step-by-step explanation:
Write out 5t^2 3t 5t^2
-------- . Invert --------- and multiply ---------- by the result:
8x^2 (x^2) 8x^2
5t^2
multiply ---------- by the result: 5t^2 5*x^2 25 t^2 x^2
8x^2 ------- * --------- = ----------------
8x^2 3t 8x^2 (3t)
Reducing this, we get 25t
-------
24x
Answer:
36
Step-by-step explanation:
In this example, s=6
6^2=36
or you can think about it like this:
you have 6 squares across and 6 down, how many do you have totle?
■■■■■■
■■■■■■
■■■■■■
■■■■■■
■■■■■■
■■■■■■
Then count them for a totle of 36
