Answer:
Step-by-step explanation:
Mixed number Improper fraction
a) 1 + 1 + 1/3 = 
7/3
b) 1 + 1 + 1 + 5/8 = 
29/8
c) 1 + 1 + 1 +2/4 = 
14/4
Answer:
f(x) = 2 ( x + 7/4)2 - 25/8
Step-by-step explanation:
Calculate for the mean/ average of the given numbers:
μ = (1 + 2 + 3 + 4 + 5) / 5 = 3
Then, we calculate for the summation of the squares of differences of these numbers from the mean, S
S = (1 - 3)² + (2 - 3)² + (3 - 3)² + (4 - 3)² + (5 - 3)²
S = 10
Divide this summation by the number of items and take the square root of the result to get the standard deviation.
SD = sqrt (10 / 5) = sqrt 2
SD = 1.41
Thus, the standard deviation of the given is equal to 1.41.
Here's the answer, using the quadratic formula
