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
Answer:
A) 41 / 93
2) 20 / 93
3) No
Step-by-step explanation:
With nuts total = 186-104 = 82
Chocolate chips with nuts = 82-40 = 42
2/3 of cookies are chocolate chip.
So,
2/3 * Total
=> 2/3 * 186
=> 2 * 62
=> 124 chocolate chip cookies
A) Probability of having nuts = With nut cookies / Total
=> 82 / 186
=> 41 / 93
B) Probability of Oatmeal raisin cookie having nuts = Oatmeal nut cookies / Total
=> 40 / 186
=> 20 / 93
C) They are not independent of each other. They are dependent on each other. If they were independent their probability were to be same.

Its 34
Because it shoukd equal 180 so when you do 101+45= 146 then you subtract 180-146= 34
I'll offer you a deal in return for your 5 points: I'll solve it . . . . You check it.
<u>-1/2x - 7 = -11</u>
Add 7 to each side: -1/2 x = -4
Multiply each side by 2 : - x = -8
Multiply each side by -1 : <em> x = 8</em>

Answer:
Step-by-step explanation:
The next number is 31.
3 + 1 = 4
4 + 2 = 6
6 + 3 = 9
9 + 4 = 13
13 + 5 = 18
18 + 6 = 24
24 + 7 = 31
The point-slope formula:
We have (-2, 1) and (1, 7).
Substitute:
