Answer:
12x = 84
x = 7
Step-by-step explanation:
12x = 83 1/3 + 2/3
12x = 84
x = 84/12
x = 7

3a(4a^2 - 5a + 12)=12a^3-15a^2+36a (C)
I think the group 2 survey is likely to be biased towards people who are not too keen on zoos since all the values are small.
From group 1 and 3 the mean number of visits are
(4 + 10 + 6 + 3 + 8 + 7 + 9 + 3 + 4 + 7) / 10
= 61/10
mean = 6
Answer:
-4 < x ≤ -3
Step-by-step explanation:
The compound inequality needs to be separated into its two parts in order to obtain a solution.

We can do a little preliminary work to make the solutions easier.
2x +6 ≤ x +3 < 3x +11 . . . . . given
x +3 ≤ 0 < 2x +8 . . . . . . . . subtract x+3
<h3>left side</h3>
x +3 ≤ 0
x ≤ -3 . . . . . . . subtract 3
<h3>right side</h3>
0 < 2x +8
0 < x +4 . . . . divide by 2
-4 < x . . . . . . subtract 4
<h3>solution</h3>
Now, we can rearrange these back into a compound inequality.
-4 < x ≤ -3
