Answer: (a) spuriousness relationship
Step-by-step explanation:
Spurious occurs between two variables that are actually caused by a third variable. Examples is like a number of teachers in region and number of people learn from college.
It means try to figure out the question by using the things with the same variable. so if it says “x + 6 = 13 and x = 8 then you use the x = 8 to figure out x + 6 = 14
Answer:
A = (12h x b1) + (12h x b2)
A = 12hb1 + 12hb2
A - 12hb1 = 12hb1 - 12hb1 +12hb2
A - 12hb1 = 12hb2
(A - 12hb1) / (12h) = (12hb2) / (12h)
b2 = (A - 12hb1) / (12h)
Answer:
r= 2.5 and s=3
Step-by-step explanation:
2r plus 6r equals 8r
-3s and 3s cancell eachother out
and 14 plus 6 is 20
with leaves us with
8r=20
20 divided by 8 is 2.5
now we go back to the orginal problems
2 times 2.5 is 5
14 minus 5 is 9
9 divided by 3 is 3
so s=3
but to check this all you would use r=2.5 and s=3 in the othe equsion
6 times 2.5 is 15
and -3 times 3 is -9
15-9= 6
