Answer:
see below
Step-by-step explanation:
total - no nuts = nuts 186 - 104 = 82
total - o raisin = chip = 82 - 40 =42
2/3 of the cookies are c chip 2/3 * 186 = 124
124- 42 = 82 no nuts
104 - 82 = 22
40 +22 = 62
c chip o raisin total
nuts 42 40 82
no nuts 82 22 104
total 124 62 186
P ( nuts) = number of nuts / total in the total column 82 / 186 =41/93
P (nuts | oatmeal) = nuts / total in the oatmeal column =40/ 62 =20/31
They are not independent
They need to have the same probability to be independent

Hello,
A cubic polynomial with -2,1,2 as roots is
f(x)=k*(x+2)(x+1)*(x-2)=k(x²-4)(x+1)=k(x^3+x²-4x-4)
Looking the answers ==>k=1
==>Answer A
Amount raised from selling candy bars = $ 1036.25.
Amount raised from dance ticket sales = $524 and
Amount raised from valentines flower sales = $206.58.
In order to find the amount your class raise altogether, we need to add all those amounts.
Total amount = $ 1036.25 + $524 + $206.58 = $1766.83.
Therefore, your class raise $1766.83 altogether.
