All you need to know is that a km is 1000 m ( as the prefix kilo always means 1000 let it be even 1kg and that is equal to 1000g )

also know

that a 100 cm is 1 m and that's cause the prefix centi is 10^–2 (0.01)

answering your question

a) 5km = 5000m

5km and 20m in m is 5000m + 20m = 5020m

b) 13 cm = 13/100m = 0.13m

7m and 12cm is 7m + 0.13m = 7.13m.

remember

1km = 1000m

100cm = 1m

A computer company produces an extremely light laptop and they claim it is the lightest on the market weighing only 32 ounces. t
Darina [25.2K]

Solution: We are given:

\mu=0.33,  \sigma =0.7

Let x be the weight (oz) of laptop

We have to find P(x>32)

To find the this probability, we need to find the z score value.

The z score is given below:

z=\frac{x-\mu}{\sigma}

       =\frac{32-33}{0.7}

       =-1.43

Now, we have to find P(z>-1.43)

Using the standard normal table, we have:

P(z>-1.43)=0.9236

0.9236 or 92.36% of laptops are overweight
