Answer:
2/1
Step-by-step explanation:
x1=1 ,y1=3
x2=2 , y2=5
then
m= 5-3/2-1= 2/1

Answer:
42
Step-by-step explanation:
Answer:
the answer is 148
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.
