Answer:

1 cm : 10 cm

Step-by-step explanation:

If you put this into fraction form (15/150) and divide the numerator and denominator by 15, you will get 1/10. This means that for every 1cm on the paper, the couch is actually 10cm long (in that place) in real life.

Answer:

6.7% of employees at Solar Systems, Inc. are younger than 30 years old

Step-by-step explanation:

The mean of ages of the employees at Solar Systems is 32.7 years

Mean = $\mu = 32.7$

Standard deviation = $\sigma = 1.8 years$

We are supposed to find What percentage of employees at Solar Systems, Inc. are younger than 30 years old i.e.P(x<30)

So, $Z=\frac{x-\mu}{\sigma}$

$Z=\frac{30-32.7}{1.8}$

Z=-1.5

Refer the z table for p value

So,p value = 0.0668

So P(x<30)=0.0668= 6.68% = 6.7%

So, 6.7% of employees at Solar Systems, Inc. are younger than 30 years old

Hello,

There is a mistake: it is 816 cm² !!! (an area)

length are multiplied by 2,
so area are mutiplied by 2²=4
Area B=816*4=3264 (cm²)
