Answer:
3.74
Step-by-step explanation:
First, we can place the square root of fourteen between it's two closest square roots:
√9 < √14 < 16
3 < √14 < 4
Now since 14 is closer to 16 than 9, we can do this:
3.9^2 = 15.21
3.8^2 = 14.44
3.7^2 = 13.69
We can see that √14 must be between 13.69, and 14.44, which are 3.7^2 and 3.8^2, so we know that √14 must be between those numbers. If we go even further, then:
3.72^2 = 13.83
3.73^2 = 13.91
3.74^2 = 13.98
3.75^2 = 14.06
We can see that 3.74^2 is the closest to 14, only .02 away from the actual number, so 3.74 is our estimate for the square root of fourteen.

<h3>What is percentage?</h3>
The term "percentage" comes from the Latin phrase "per centum," meaning "by the hundred." Percentages represent fractions with a denominator of 100. In other terms, it is the relationship between portion and whole in which the value of the whole is always assumed to be 100.
Now according to the question;
Let x represent the total number for cruise passengers during 2017.
In 2018, a 6.7% rise in x results in 28.5 million cruise passengers.
So, 106.7 % of x = 28.5
Multiplying both sides by 100;
Dividing both sides by 106.7;
x = 26.7
Therefore, the number of cruise passengers in 2017 must have ranged from 26.7 million.
