Answer:
Step-by-step explanation:
The only place that the function is increasing is [-3, -1] (learn your interval notation). At x = -3, y = -11; at x = -2, y = -6 (-6 is greater than -11); and at x = -1, y = -1 (-1 is greater than -6). The next x value, 0, returns a y value of -2. But -2 is less than -1, the value before it, so it begins deceasing again at x = 0.

Step-by-step explanation:
3/8 x 9 (or 9/1)
Answer: 296
Step-by-step explanation:
Unique addresses (population size) = 1,346
Sample size = 50
Number of children - - - - - - - No of household
0 - - - - 5
1 - - - - 11
2 - - - -13
3 - - - - 10
4 - - - - 9
5 - - - - 2
Number of households with more than 3 children :
That is, households with 4 and 5 children
Total = 9 + 2 = 11 households
Therefore, proportion of households with more than 3 children :
(11 / sample size) × population size
(11 /50) × 1346 = 296.12
Approximately 296 households
