Answer:

The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles is 102.

Step-by-step explanation:

Consider the provided information.

Emanuel surveyed a random sample of 50 subscribers to Auto Wheel magazine about the number of cars that they own. Of the subscribers surveyed, 15 own fewer than 2 vehicles.

The probability of fewer than 2 vehicles is: $\frac{15}{50}$

Now it is given that there are 340 subscribers to Auto Wheel magazine.

Simply multiply the probability of fewer than 2 vehicles with 340.

$P=\frac{15}{50} \times 340=102$

Hence, the most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles is 102.

Select the correct answer.

lara [203]

First convert them to fractions (the answer choices are fractions):

a) 0.333... = 1/3
b) 0.555... = 5/9

Now add a and b:

1/3 (or 3/9 for a common denominator) + 5/9 = 8/9

That fraction is in simplest form, so leave it as it is.

Hope this helps!
