adelina 88 [10]

Answer:

The answer is explained below

Step-by-step explanation:

What use are statistics if there is no engineer to use them? In other words, a statistician corrects, improves, reinforces, and supports an engineer in building / designing / developing a new product and / or improving an existing product.

The statistician provides a special kind of vision through which I see the same problem in a completely different vision. So you can see the strengths, weaknesses of my product and the promise of improvements that can be made.

Each class of statistics is essential for a student to see and understand a problem in a whole new way where it is much easier to understand information.

A boat traveled 37 miles in 2 hours. At this<br> rate, how many miles will the boat travel in
Inessa [10]

<u><em>Answer:</em></u>

i. The boat will travel 18.5 miles in one hour

ii. The boat will travel 9.25 miles in half an hour

iii. The boat will travel 27.75 miles in one and a half hours

<u><em>Explanation:</em></u>

We are given that the boat travel 37 miles in 2 hours

To get the miles traveled, we can simply use cross multiplication

<u>i. Miles traveled by the boat in one hour:</u>

37 miles .....................> 2 hours

x miles ........................> 1 hour

x = \frac{37*1}{2}=18.5 miles

<u>ii. Miles traveled in half an hour:</u>

37 miles .....................> 2 hours

x miles ........................> 0.5 hour

x = \frac{37*0.5}{2}=9.25 miles

<u>iii. Miles traveled in an hour and a half:</u>

37 miles .....................> 2 hours

x miles ........................> 1.5 hour

x = \frac{37*1.5}{2}=27.75 miles

Hope this helps :)
