Assume that females have a pulse right now to normally distributed with a mean of 75 beats per minute and a standard deviation of 12 beats per minute complete parts a through c below if 4 adult females are randomly selected find the probability that they have pulse rates with a mean less than 78 beats per minute

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
