Answer: labor force participation rate =60%

unemployment rate = 6.67%

Step-by-step explanation:

The labor force participation rate is computed as

$\text{labor force participation rate}=\dfrac{\text{Total employed persons}}{\text{Total population}}$

i.e. $\text{labor force participation rate}= \dfrac{72000}{120000}$

$= 0.6\ or\ 60 \%$

The unemployment rate is computed as:

$\text{unemployment rate}=\dfrac{\text{Number of personsdon't have jobs }}{\text{Total population}}\\\\\text{unemployment rate}=\dfrac{8000}{120000}\\\\\text{unemployment rate}=0.0667\ or\ 6.67\%$

Hence, labor force participation rate =60%

unemployment rate = 6.67%

Answer:

1. y² - 3x - 18

2. 4x² - 33x + 35

3. 12x² - 11x + 2

Step-by-step explanation:

All we do with these questions are expanding the factored binomials. Use FOIL:

1. y² + 3y - 6y - 18

y² - 3y - 18

2. 4x² - 28x - 5x + 35

4x² - 33x + 35

3. 12x² - 3x - 8x + 2

12x² - 11x + 2
