Answer:
Yes,
You need 88 points.
Step-by-step explanation:
What you need to do here is to set up an equation using algebra (I do this in my master's degree to determine my grade).
= 400
x = 320
Your target required points is 320.
320 - 232 = 88 points.
You need 88 points on the exam to get the 80%.
The standard scientific notation is expressed according to the expression
. The expression written in scientific notation is 2.226* 10⁸
<h3>Scientific notations</h3>
The standard scientific notation is expressed according to the expression![A\times 10^n](https://tex.z-dn.net/?f=A%5Ctimes%2010%5En)
where
- A is any real value between 1 and 10
- n is any integer
Given the expression
![(5.3\times10^4)(4.2\times10^3)](https://tex.z-dn.net/?f=%285.3%5Ctimes10%5E4%29%284.2%5Ctimes10%5E3%29)
This can be expressed as:
= (5.3 * 4.2)(10⁴ * 10³)
= 22.26 * 10⁷
= 2.23 * 10⁸
Hence the expression written in scientific notation is 2.226* 10⁸

Answer:
C) One student is chosen from Classroom A, then a second student is chosen from Classroom A.
Step-by-step explanation:
The choice of each student being chosen is dependent on the first one, as there will be one less person to choose from, leading to a higher chance of the another being chosen.
