Answer:
d. Yes, there appears to be a linear trend, but the fit is not exact.
Step-by-step explanation:
Answer: She will need the minimum of 12 months
7000-2500= 4500
4500/2=11.25
11.25 rounded up is 12
Answer:
5 hours
Step-by-step explanation:
Let s and w represent hours spent traveling south and west, respectively. The problem statement tells us ...
s + w = 8 . . . . . . total trip time
344s + 351w = 2773 . . . . total mileage (using d = s·t)
By Cramer's rule, we can find the value of s as ...
s = (1(2773) -351(8))/(1(344) -351(1)) = -35/-7 = 5
The plane was heading south for 5 hours.

<em>Comment on Cramer's rule</em>
For the equations ...
ax +by = c
dx +ey = f
The solution for x can be found to be ...
x = (bf-ec)/(bd-ea)
Similarly, the solution for y is ...
y = (cd-fa)/(bd-ea)
The total weight of Nico's diamond is 564 ounces
<h3>
Weights</h3>
The weights of the diamond are given as:
5, 13, 12, 4, 9, 8, 15, 210, and 6 ounces
<h3>
Total weights</h3>
Start by calculating the total weights


The above sum represents the total weights of Jack's diamonds.
So, the total weights of Nico's diamond is calculated as:


Hence, the total weight of Nico's diamond is 564 ounces

The points for this graph are (3,0) and (0,2). Looking at the point to the right, you go left or right before you go up and down. You first go to the right 3 times, but you don't go up or down. So this point is (3,0). Looking at the next point you don't go left or right at all, but you do go up two spaces, so this point is (0,2).
