Answer: a. 0.9876
Step-by-step explanation:
Given : The distribution of total body protein in healthy adult men is approximately Normal with mean 12.3 kg and standard deviation 0.1 kg.
and ![\sigma=0.1](https://tex.z-dn.net/?f=%5Csigma%3D0.1)
sample size : n= 25
Let x denotes the total body protein in healthy adult men in the sample.
Then, the probability that their average total body protein is between 12.25 and 12.35 kg will be :-

Answer:
435 ft
Step-by-step explanation:
area of triangle:
A = (b x h) : 2
A = (15 x 4) : 2
A = 60 : 2
A = 30 ft
area of rectangle:
A = b x h
A = 25 x 15
A = 375 ft
area of the yard = area of the triangle + area of the triangle + area of the rectangle (Here, both triangles have the same area.)
area of the yard: 30 + 30 + 375 = 435 ft.
So, the area of the yard is 435 ft.
