The answer for -2.5x-10=40 would be:
x = - 20.
In form ax + b = c: 2x - 8.4 = 5
Solution to equation: x = 6.7
Step-by-step explanation:
4x - 8.4 = 2x + 5
2x - 8.4 = 5
2x = 13.4
x = 6.7

To find the median, arrange all the numbers from least to greatest.
10, 31, 36, 36, 38, 42, 47, 48, 49, 52
The middle two numbers are 38 and 42. Take their average.
40
40 is the median of 10, 31, 36, 36, 38, 42, 47, 48, 49, and 52.
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
