Answer:

Explanation:
You are comparing irrational numbers.
By inspection, i.e. at first sight you can only compare
because they have the same radicand.
You can order: 
You can introduce the 2 inside the radical by squaring it:

Since 5 is between 3 and 12, you can order:
Which is:
You must know that π ≈ 3.14.
5 is less than 9 and the square root of 9 is 3; hence,
and 
Now you must determine whether π is less than or greater than 
Using a calculator or probing numbers between 3 and 4 you get 
Hence, the complete order is:
Infinite solutions; both equations are the same.

Answer:
D and A
Step-by-step explanation:
96 - 12 is 24, then you divide by 12. A and D are the same but D is Just A simplified
The second one. You can draw it out and test it yourself.
Answer:
option B
Step-by-step explanation:
Given,
mean result (μ) = 65
standard deviation (σ)= 15
probability that student will score between 50 and 80
= 
= 
= 
= P(Z < 1) - P(Z < -1)
Using z table,
= 0.8413 - 0.1587
= 0.6826
the correct answer is option B
