Gina wrote the following paragraph to prove that the segment joining the midpoints of two sides of a triangle is parallel to the third side:Given: ΔABCProve: The midsegment between sides Line segment AB and Line segment BC is parallel to side Line segment AC.Draw ΔABC on the coordinate plane with point A at the origin (0, 0). Let point B have the ordered pair (x1, y1) and locate point C on the x-axis at (x2, 0). Point D is the midpoint of Line segment AB with coordinates at Ordered pair the quantity 0 plus x sub 1, divided by 2. The quantity 0 plus y sub 1, divided by 2 by the slope formula. Point E is the midpoint of Line segment BC with an ordered pair of Ordered pair the quantity of x sub 1 plus x sub 2 divided by 2. The quantity of 0 plus y sub 1 divided by 2 by the slope formula. The slope of Line segment DE is found to be 0 through the application of the slope formula: The difference of y sub 2 and y sub 1, divided by the difference of x sub 2 and x sub 1 is equal to the difference of the quantity 0 plus y sub 1, divided by 2, and the quantity 0 plus y sub 1, divided by 2, divided by the difference of the quantity x sub 1 plus x sub 2, divided by 2 and the quantity 0 plus x sub 1, divided by 2 is equal to 0 divided by the quantity x sub 2 divided by 2 is equal to 0 When the slope formula is applied to Line segment AC the difference between y sub 2 and y sub 1, divided by the difference of x sub 2 and x sub 1 is equal to the difference of 0 and 0, divided by the difference of x sub 2 and 0 is equal to 0 divided by x sub 2 is equal to 0, its slope is also 0. Since the slope of Line segment DE and Line segment AC are identical, Line segment DE and Line segment AC are parallel by the definition of parallel lines.Which statement corrects the flaw in Gina's proof?

Which statements are true the ordered pair (1, 2) and the system of equations? y=−2x+47x−2y=3 Select each correct answer. When (1, 2) is substituted into the second equation, the equation is true. When (1, 2) is substituted into the second equation, the equation is false. When (1, 2) is substituted into the first equation, the equation is true. When (1, 2) is substituted into the first equation, the equation is false. The ordered pair (1, 2) is not a solution to the system of linear equations. The ordered pair (1, 2) is a solution to the system of linear equations.

Jen's commute to work requires that she take the blue subway line, then transfer to the red line. the length of the trip on the blue line has a mean of 18 minutes with a standard deviation of 2 minutes. the red line trip takes 12 minutes with a standard deviation of 1 minute. the waiting time between when she gets off the blue line and her red line train arrives has mean of 10 minutes and a standard deviation of 5 minutes. assume (perhaps unrealistically) that these times are independent random variables. what are the mean and standard deviation of her entire commute?
