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%

Simplify the expression 10-4x(6+5-1) divided by 8+7

Eddi Din [679]

Simple,

writing out the problem...

$\frac{10-4x(6+5-1)}{15}$

Simplify it...

-4x(6+5-1)

-4x(11-1)

-4x(10)

-40x

Making it look like...

$\frac{10-40x}{15}$

Cancel out the common factors...

Thus making the answer:

$- \frac{2(4x-1)}{3}$ .

You were told that the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distrib

uysha [10]

Answer:

Step-by-step explanation:

Given that that (X) the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distribution with a mean of 15 seconds.

i.e. X is normal with mean = 15 and unknown std deviation $\sigma$

Given that $P(X$

i.e. P( $z$

z=-1.475 (from normal table)

Hence $\frac{13-15}{\sigma}=-1.475\\\sigma = 1.356$

Using this we find P(X>17) = $P(Z>\frac{17-15}{1.356} \\=P(Z>1.475)\\=0.5-0.428\\=0.072$

QUICK HELP PLEASE!!!!

h = 2t - d

multiply both sides by 2 to eliminate the fraction

2t = d + h

subtract d from both sides

2t - d = h ⇒ h = 2t - d
