Answer:

Step-by-step explanation:

→ Substitute in the numbers

1\frac{2}{5} -\frac{5}{6}

→ Simplify

1\frac{2}{5} -\frac{5}{6}=\frac{7}{5} -\frac{5}{6}=\frac{42}{30} -\frac{25}{30} =\frac{17}{30}

Which relationship would most likely have a positive correlation?
tiny-mole [99]

Answer:

C.

Step-by-step explanation:

The only thing to do here is just check all of the answers.

A makes no sense, as the number of keys on a keyboard doesn't affect the amount of memory in a computer at all (no correlation).

B makes a bit more sense, but it's still wrong. If a train travels faster, it gets places quicker, or the time goes down. If (If one goes up, the other goes down) is true, then you have negative correlation.

C makes the most sense, as if there's more people at a game, then those more people will probably buy more hot dogs. If (If one goes up, so does the other) is true, then you have positive correlation, which is what we want.

No. They are not equivalent.

=> \frac{6}{10} \neq  \frac{5}{10}

Therefore, 3/5 and 1/2 are not equivalent.
