Answer:
Step-by-step explanation:
the shape is a trpizoid with height y
A=(a+b)/2 *h (a=2x=4cm, h=y=4cm, b=2z=12 cm
A=(4+12)/2 * 4
Area=16/2 *4=8*4= 32 cm²
Your using the distributive property in your example, hope that helps.
Answer:

And we can find this probability with the complement rule:

Step-by-step explanation:
For this case we define the random variable X ="driving distance for the top 100 golfers on the PGA tour" and we know that:

And for this case the probability density function is given by:

And the cumulative distribution function is given by:

And we want to find this probability:

And we can find this probability with the complement rule:
