Area under the curve: 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 1.48) =
b) P(Z > 1.48)=
c) P(-0.4 2) =
d) P( | Z | >2)=

step-by-step explanation:

c

step-by-step explanation:

answer: i dont know but if you try hard you will get it right : )

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
