Suppose that you have been growing pigs in your farm. In 2015, you had 25 piglets and measured birth weight in kilograms. The data were assigned in the array named weight2015 The following MATLAB commands give: mean (weight2015) ans = 1.44 >std (weight2015) ans = 0.39 Note that the answers were already trimmed up to the significant figures defined by your accuracy in weight measurement What is the population mean and the population standard deviation of piglet birth weight of year 2015 in your farm?

mean = 1.44

S.D = 0.39408

Step-by-step explanation:

The population mean of piglet birth weight of year 2015 in the farm is 1.44

The population SD of piglet birth weight of year 2015 in the farm is

E(S) =[sqrt(2/(n−1)) Γ(n/2)/Γ((n−1)/2)]σ

0.39 =[sqrt(2/(25−1)) Γ(25/2)/Γ((24)/2)]σ

0.39 = 0.9896404σ

σ = 0.39/0.9896404 =0.39408

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
