Please help me with this question
Natali5045456 [20]
Again, In this question too you need to substitute the given variable values into the original expressions. Here, "x" is given as a value of "12" and the variable of "y" is given as as value of "2". A single variable of "x" in the numerator is given in the expression. On the denominator the variable of "y" with a value of "2" is multiplied by a numbered value of "3". So, now showing this by the help of LaTeX.

\mathbf{Since, \: x = 12, \: y = 2}

\mathbf{\therefore \quad \dfrac{12}{3 \times 2}}

\mathbf{\therefore \quad \dfrac{12}{6}}

\mathbf{2}

\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is: \: B) \: 2}}}

Hope it helps.

Choose the scatter plot that shows a negative correlation.
Alenkinab [10]

Negative correlation between two variables means when x is increasing but y is decreasing or vice versa.

First graph of suffered animals and children shows a positive slope which means if age of child increasing then numbers of suffered animal is also increasing.So, the first graph show a positive correclation.

Second graph of survey of adults doesn't represnt any distinct relationship as the data scattered randomly everywhere in the graph. So, it's showsa very week correlation.

Third graph of speed and MPG shows a negative slope as speed is increasing then MPG is decreasing. So, the third graph (speed and MPG) shows a negative correlation.
