Assume that females have pulse rates that are normally distributed with a mean of 73.0 beats per minute and a standard deviation Of 12.5 beats per minute, If I adult female is randomly Selected, find the probability that her pulse is less than 80 beats per minute.​

up

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

168

step-by-step explanation:

i am pretty sure that the answer is 168

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

im pretty sure its
