Answer:
15.8 % ???
at z = 1 p=.8413
I guess the question is asking 1-.8413 = 15.8 %
Step-by-step explanation:
50 x 3.14 = 157 i think this is the answer
2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.
-15,-5,-2,1,3,8 it's pretty simple
