Answer:
Step-by-step explanation:
<u>Finding the missing side</u> :
- x² = 13² - 12²
- x² = 169 - 144
- x = √25
- x = 5
<u>Taking the cot value</u> :
- cot T = adjacent / opposite
- cot T = -5/12 (As cot is negative in Quadrant 2)
First, we expand the equation:
Then, we combine certain terms in order to simplify them using trigonometry identities.
Note these identities:
Pythagoran relation:
Sum and Difference Formula/Identities:
Thus, if we apply these identities, the simplified equation would be:
Simplying further, the answer would be
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
