3.1 Area under the curve, Part I: Find the probability of each of the following, if Z~N(μ = 0,σ = 1). (please round any numerical answers to 4 decimal places)

a) P(Z < -1.35) =

b) P(Z > 1.48) =
0.069

c) P(-0.4 < Z < 1.5) =

d) P(| Z | >2) =

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.

your answer would be 12

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
