Answer:

Step-by-step explanation:

We know that 60% of drivers are over 30 years old and 5% of the 60% will be prosecuted for driving offence during the year. We know that 40% are 30 years and younger and 10% of that 40% will be prosecuted. The possibility of a driver 30 and younger being prosectued is:

$=0.4\cdot{0.1}=0.04$

Therefore the probability is 4%

A certain human red blood cell has a diameter of 0.000007 meters.Write an expression that represents this diameter, in meters in

By definition we have to:
Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large or too small to be written in a conventional manner.
The use of this notation is based on powers of base 10.
A number written in scientific notation follows the following pattern:
$m * 10 ^ e
$
The number m is called "mantissa" and e the "order of magnitude"
For this case we have:
0.000007
Using the definition, we have that the measure of the diameter in scientific notation is:
$0.000007 = 7 * 10 ^ {-6}
$
Answer:
An expression that represents this diameter, in meters in scientific notation is:
$7 * 10 ^ {-6}$
