An environmentalist wants to find out the fraction of oil tankers that have spills each month. Step 1 of 2 : Suppose a sample of 1453 tankers is drawn. Of these ships, 1018 did not have spills. Using the data, estimate the proportion of oil tankers that had spills. Enter your answer as a fraction or a decimal number rounded to three decimal places.

p = 0.299

Step-by-step explanation:

A proportion is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

We want to estimate the proportion of oil tankers that had spills. Of the 1453, 1018 did not have spills, and 1453 - 1018 = 435 had. So

Total outcomes:

All the 1453 tankers, so

Estimating the proportion

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
