The answer should be 3? Geometry.
Answer:
1. 11.8x9.8=115.64 115.64/2=57.82 (57.82Inches)
2. 12x5=60 60/2=30 (30m)
3. 25x9=225 9x9=81 81/2=40.5 225-40.5=184.5 184.5/92.25 (92.25ft)

1. Any fraction that you multiply the numerator by the same number as the denominator.
Example:
1 x 2 = 2
-------------
2 x 2 = 4
2. The simplest form of 24/60 is 2/5 I believe.
3. 4/9
4. 23/8

Answer:

So then the best answer for this case would be:
C. 2.78
Step-by-step explanation:
For this case we have the following probabability distribution function given:
Score P(X)
A= 4.0 0.2
B= 3.0 0.5
C= 2.0 0.2
D= 1.0 0.08
F= 0.0 0.02
______________
Total 1.00
The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.
If we use the definition of expected value given by:

And if we replace the values that we have we got:

So then the best answer for this case would be:
C. 2.78
