Write the shortest distance of points a, b, c, and d from the y-axis

natta225 [31]

Point A: 60

Point B: 60

Point C: 50

Point D: 50

The distance a point is from the y axis is the absolute value of the x-coordinate, because the x-coordinate is how far (and the direction) to go from the y axis. However, because it also takes into account the direction, we have to find the absolute value of it (so it is positive), since distance has to be positive.

Answer:

μ = 1.877

Step-by-step explanation:

Data provided in the question:

Number of data samples, n = 10

Data: 2.18, 2.03, 1.56, 1.09, 1.56 ,2.28 ,1.62 ,2.02 ,2.11 ,2.32

Now,

Mean is calculated using the formula as:

Mean, μ = $\frac{\textup{Sum of all the observations}}{\textup{Total number of observations}}$

or

Mean, μ = $\frac{\textup{2.18 + 2.03 + 1.56 + 1.09 + 1.56 + 2.28 + 1.62 + 2.02 + 2.11 + 2.32 }}{\textup{10}}$

or

Mean , μ = $\frac{18.77}{10}$

or

Mean , μ = 1.877
