Answer:
3x-12=y
which equals to
1/y=1/(3x-12)
Now,multiply both sides by x
x/y=x/(3x-12)
8x/2y=4x/y=4x/(3x-12)
Step-by-step explanation:
''.''
W=kxp
where
k is the constant of proportionality given by:
k=w/xp
<span> If w=78 when x=2 and p=10 then
</span>k=78/(2*10)
k=3.9
thus the formula is:
w=3.9xp
b] <span>find x when w=858 and p=5.5
plugging the values in the formula we get:
858=3.9</span>×5.5×x
hence
x=858/(3.9×5.5)
x=358/21.45
x=16.69

Step-by-step explanation:
Which display is more useful for approximating the minimum distance?
More useful is box-and-whisker plot (second display) because there you can exactly see that the minimum distance is 10 km (left point at the plot).
Which display can be used to find that there were 23 vehicles at Nam’s Used Car Lot?
More useful is first display, because you see the following information:
Distance Number of vehicles
0 - 50 3
50 - 100 4
100 - 150 5
150 - 200 6
200 - 250 3
250 - 300 2
Total number of vehicles = 3 + 4 + 5 + 6 + 3 + 2 = 23
