Suppose humans have weights which are normally distributed with mean 170 lbs and SD 50 lbs. If 400 humans are selected at random

MrRa [10]

Answer:

$P(x< 175)= 0.9772$

Explanation:

given,

mean weight of human = μ = 170 lbs

standard deviation = SD = 50 lbs

N = 400 humans

By using central limit theorem,

P (x< 175)

$P(x< 175)= P(z$

$P (x< 175)= P(z$

using z-table

$P (x< 175)= 0.9772$

hence, the probability that total weight is less tan 175 lbs is equal to

$P(x< 175)= 0.9772$

how many times will the kinetic energy of a body increased if the it's speed is tripled show by calculation

Orlov [11]

Answer:

we know that

ke=1÷2×mv^2

and when speed become triple of original then new speed become 3v

then,new ke=1÷2×m(3v)^2

=1÷2×9mv^2

9×original ke

hence ke will increase by 9 times
