Mean = 40 and Sd = 10

Need to find the value of m for the area given:

From left to right the normal dist has an area of 0.97

How do I find this?

This is what I did, normalcdf (-100,-3) = 0.00135

(Put -100 as some big number [Should be infinity])

then add to 0.97 = 0.97135, then I used invNorm (0.97135)

Don't know where I went wrong! What is the mean and sd for in this question O.o?

The answer is 58.81 but I cant get it

Please help!
