Answer: The proportion of oil tankers that had spills is or 0.329.
Step-by-step explanation:
Since we have given that
Number of tankers is drawn = 474
Number of tankers did not have spills = 318
Number of tankers have spills = 474 - 318 = 156
Proportion of oil tankers that had spills is given by
Hence, the proportion of oil tankers that had spills is or 0.329.
Using the given property, we conclude that:
f(4) = 8
<h3>
What is the value of f(4)?</h3>
We know that our function has the property:
5*f(x) = f(5*x)
Now, we also know that:
f(20) = 40
Notice that we can rewrite:
f(20) = f(5*4)
Using the above property, we know that:
f(20) = f(5*4) = 5*f(4) = 40
Using the last part:
5*f(4) = 40
f(4) = 40/5 = 8
f(4) = 8

Answer: 37.5 minutes
Step-by-step explanation:
It takes Jahanna 50 minutes to deliver to 40 customers.
On Sunday however, she has to deliver to only 30 customers.
Assume that the amount of time it will take her is x minutes and use direct proportion:
50 minutes : 40 customers
x minutes : 30 customers
Cross multiply:
40x = 50 * 30
40x = 1,500
x = 1,500/40
x = 37.5 minutes
7.55 is the answer
