Answer:
6 cubic cm
Step-by-step explanation:
3 · 3 · 2 = 18
18 · 1/3 = 6
This trend line shows a general pattern, and since we are with biological samples this trend line will not always be true. The outliers could be from either a genetic difference or an environmental difference that occured in the persons life.
Answer:
Yes
Step-by-step explanation:
Let L be the low copper alloy and H be the high copper alloy.
We need 0.15L + 0.60H = 0.42 and L + H = 100
L=100 - H
Substituting this into the second equation for L, we get:
0.15(100-H) + 0.60H = 0.42(H+L)
15 - 0.15H + 0.60H = 0.42(H+100-H)
15 + 0.45H = 0.42(100)
0.45H = 42 - 15 = 27
H = 27/.45 = 60 lbs
Back substitution, L = 40 lbs.
