Answer:
0.081,0.2621,0.645,0.919
Step-by-step explanation:
Let X be the average speed of a car driving down freeway
Given that X is normal with mean as 70mph with a standard deviation of 5mph.
To convert to Z score we do
a) the probability that a randomly selected car is driving more than 77mph
b) probability that a randomly selected car is driving between 65 and 69 mph
=
c) the probability that a randonly selected car is driving between 67 and 77mph
=
d) the probability that a randomly selected car is driving less than 77mph

Based on the hints of distinguishing between <em>radical</em> and <em>non-radical</em> numbers, we have the following lists:
,
, 2.5,
- 3.01,

, - 4.1, 4.01,
- - 2.5,

, 2.5
<h3>How to order numbers from least to greatest</h3>
In this question we must order sets of numbers in ascending order. A hint consists in comparing <em>non-radical</em> numbers with the <em>closest</em> <em>radical</em> numbers whose results are integers.
In consequence, we obtain the following orders:
- 3.01,
- - 2.5,
