# So i have this equation: 36x^2-121y^2=49 which i rearranged to 36x^2/49-121y^2/49=1 so i want to go from here and find the eccentricity, foci, asymptotes

but i'm getting myself confused. since my equation is of the form x^2/a^2-y^2/b^2=1

both a and b would be which makes my eccentricity e=sqrt(1+49/49) but this is at odds with the software i'm using to practice this.

which part am i getting myself tied up with? you!

23) 84% of a contractor’s jobs involves electrical work. 75% of a contractor’s jobs involve plumbing work. Of the jobs that involve plumbing, 90% of the jobs also involves electrical work. Let E = jobs involving electrical work L = jobs involving plumbing work Suppose one of the contractor’s jobs is randomly selected. Using the sixth Excel worksheet, a) Find P(E). 0.84 b) Find P(L). 0.75 c) In words, what does E | L mean? d) Find P(E | L). e) Find P(E and L). f) Are E and L independent events? Why or why not? g) Find P(E or L). h) Are E and L mutually exclusive? Why or why not
