Step-by-step explanation:
So I didnt really understand the beginning but what I did was $325x24=$7800 payed in 24 months if we are adding the $4500 it would be
$7800+$4500=$12300
You see how the a increases by 4 whenever b increases by one?
So, the equation is a=4b
Hope this helps!
Z score = 66 - 76
---------- = - 1
10
from the tables of normal distribution this corresponds to 0.34-3 of the area under the normal curve
so reuired number od students = 0.3413 * 230 = 78
23+52+34+61+30=200. Your answer of total gumballs is 200. At least I hope you meant to ask that. :)
-2 and 1 multiply to -2 and sum up to -1.
