Triangles MNP & MAB are similar (NP//AB & Angle A= Angle N (correspondent) Same for P & B
We know that MA = 67.2 -3.2 = 35.2
Since Triangles MNP & MAB are similar , then we can write the following ratio:
MN/MA=MP/MB or 67.2/35.2 =81.9/x
& x= 43 m
The mean distance for a group is the sum of individual numbers over the number of data. The mean distance of Group A is (1+1.5+3+3.2+2.8+1.5+1.8+2.5+2.2)/9=2.17 The mean distance of Group B is (<span>2+2.5+3.2+3+1.8+2.4+3+1.5+1.8)/9=2.36. Therefore, the mean is greater for group B than group A, but not doubling.</span>
7y - 3x = -5
-3x = -7y - 5
x = 7/3y + 5/3
<h3>
Answer:</h3>
<em>None of the above</em>. All the answers refer to <em>price</em>. The given equation refers to <em>value</em>. We imagine price may stay the same or actually increase year-to-year. The problem statement gives insufficient information to conclude anything about <em>price</em>.
Math is about attention to detail. The equation tells you ...
... The <em>value</em> of the boat decreases by 12% every year.
<h3>
Step-by-step explanation:</h3>
The value of the boat is multiplied by 0.88 each time X increases by 1. That means the value is 88% of what it was the year before, <em>a decrease of 12%</em>.
