What you see in the z score table is P(z< a constant), for P( z≥ a number), subtract the probability from 1:
1-0.1587=0.8413
on the z score table, you will see that p(z<1.00)=0.8413
so c=1.00
4x + 8 = -12 is the equation for this statement
Its 15 boats bcuz...252+288=540 and 540/36= 15 boats :D
2x4=8 2x2=4 4+8=12, so it is A
Here you go I hope I helped
