b) \( \begin{array}{ll}x=3 & x-y=1 \\ x=5 & x+y=7\end{array} \)

What is the largest number that evenly divides the top and bottom of \( 12 / 20 \) ? (A) 2

\( \left. \begin{array} { l } { g ( x ) = \frac { \ln ( x ) } { e ^ { x } \frac { 1 } { x ^ { 2 } } } \quad [ 2 , c ] \quad n = 6 } \\ { \frac { 6 - 2 } { 6 } = 0.666 } \end{array} \right. \)

a) \( \frac{7^{\frac{1}{2}} \cdot 7^{\frac{1}{3}} \cdot 7^{\frac{4}{6}}}{7^{\frac{5}{2}} \cdot 7^{\frac{2}{3}}}= \)

Question 24 Maria's car gets 28 miles per gallon. She puts in 6 gallons of gas. She wants to calculate how far she can drive. \( 6 \times 28 \) may be hard to do mentally. Maria knows 28 is \( 20+8 \), so she starts with the tens, computing \( 6 \times 20=120 \). Continuing this method, what does Maria compute for the ones? (A) 14 (B) 120

Choose the correct answer below. A. Increasing values of \( X \) go with increasing values of \( Y \). A correlation exists between two variables when both variables increase together. B. \( X \) causes \( Y \). If \( Y \) decreases as \( X \) increases, then \( X \) must cause \( Y \) to change. C. \( X \) causes \( Y \). If \( Y \) increases as \( X \) increases, then \( X \) must cause \( Y \) to change. D. Increasing values of \( X \) go with increasing values of \( Y \). A correlation exists between two variables when both variables decrease together. Increasing values of \( X \) go with either increasing or decreasing values of \( Y \). A correlation exists between \( X \) and \( Y \) when higher values of \( X \) consistently go with higher values of \( Y \) or when higher values of \( X \) consistently go with lower values of \( Y \). F. Increasing values of \( X \) go with either increasing or decreasing values of \( Y \). A correlation exists between two variables when both variables increase or decrease together.
