Answer:
B.
Step-by-step explanation:
Causation is often confused with correlation because they are so similar. B would mean that pollution is caused from something (lets say greenhouse gases for example) which then results in more cases of heart disease.
Causation is when the first variable may bring the second into existence or may cause the incidence of the second variable to fluctuate. So, causation is the capacity of one variable to influence another. Which, would make B, a suitable candidate.
Answer:
They are congruent
Step-by-step explanation:
They both have the sides with 15 and 12, and if you rotate it a bit it will look exactly the same.
A. because of 1x4=4 then 8x2=16
V = 1/3 area of base * height
Area of base = h [(b₁ +b₂)]/2
[(3 + 6) * 4] : 2 =
18 ft²
Volume =
18 * 3 =
54 ft³
Answer:
Sand: 21 parts.
Lime : 14 parts.
Cement: 7 parts.
Step-by-step explanation:
The number of parts is 3 + 2 + 1 = 6.
So for 42 parts we need:
Sand: 3/6 * 42 = 1/2 * 42 = 21.
Lime: 2/6 * 42 = 1/3 * 42 = 14,
Cement: 1/6 * 42 = 7.
