2x^2 + 8x + 8
= 2(x^2 + 4x) + 8
= 2 [ (x + 2)^2 - 4) + 8
axis of symmetry is x = -2 ( because of the (x + 2)^2 )
Answer:
i think it is all ready in standard form
is the original number 0.000000423 if yes then it is in standard form
Answer:
20 units
Step-by-step explanation:
The y axis is 2-6 so subtract 6 and 2 which is 4
the x axis is 3-9 so subtract 9 and 3 which is 6
The other sides are the same
4+4+6+6= 20
3/4 (x+8)=9
3/4x+6=9
-6
3/4x=3
X=4
Check
3/4(4+8)=9
3/4 (12)=9
9=9
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
