Answer:
4/5 of the cattle is left
Step-by-step explanation:
Given,
A farmer sells 2/5 of his cattle
Let "x" be the total number of cattle
Then,
sold = 2 / 5 x
Then,
Remaining = x - 2x / 5
remaining = 3x / 5
He gives 1/3 of the remainder to his son
son = 1 / 3 × 3x / 5
son = x / 5
Then,
Remaining = 3x / 5 - x / 5
Remaining = 4x / 5
Hope this answer helps you :)
Have a great day

Answer: 0.9726
Step-by-step explanation:
Given : Females have pulse rates that are normally distributed with a mean of 74.0 beats per minute and a standard deviation of 12.5 beats per minutes.
i.e. and
Let x is a random variable to represent the pulse rates.
Formula :
For n= 16 , the probability that her pulse rate is less than 80 beats per minute will be :-
Hence, the required probability = 0.9726
