Answer:
<em>100 miles.</em>
Step-by-step explanation:
When we look at the graph, we can see that they want to see <em>how far the ship will travel</em> in <em>4 hours</em>. So lets look at the graph and at 4 hours, we can see the ship will<em> travel 100 miles.</em>
Well, 4.4 + 7.7 = 12.1
So that would be 12 tonnes
<u>Or </u>
4.4 = 4 tonnes
and
7.7 = 8 tonnes
Hope this helps
Basically you multiply the probabilities
So 92/100 * 92/100 = 0.8464 so around 84-85%

12^2+x^2=(x+6)^2
144+x^2=x^2+12x+36
12x=108
x=9
-2x^4+10x^3-21x^2+19x-4
