If you have a graphing calculator, go to 2nd vars, normalcdf(.
Put 150 for the lower bound and 99999999 for the upper bound. You want to know the probability of all the values over 150. Put 131.8 for the mean and 29.12 for the standard deviation. Click paste.
Your answer will be .266
Answer:
I believe it is 11 1/4. Hope I'm right.
Step-by-step explanation:
I multiplied 2*5=10
Then I multiplied 1/4*5= 1 1/4
Then I added 10+1 1/4=11 1/4
Answer:(x-3)=-(y-5)=z
Step-by-step explanation:
Given
the point through which line passes is (3,5,0)
so we need a vector along the line to get the equation of line
It is given that line is perpendicular to both i+j & j+k
therefore their cross product will give us the vector perpendicular to both
v=(i+j)\times (j+k)=i-j+k
therefore we get direction vector of line so we can write
=t
i.e.
x=t+3,y=-t+5,z=t
