[ HELP ASAP ]Theorem: The segment joining the midpoints of two sides of a triangle is parallel to the third side and half its length. A two column proof of the theorem is shown, but a justification is missing. A triangle with vertices A at 6, 8. B is at 2, 2. C is at 8, 4. Segment DE. Point D is on side AB and point E is on side BC (Image attached for info down below in case it's too confusing to read) The coordinates of point D are (4, 5) and coordinates of point E are (5, 3) Midpoint Formula Length of segment DE is Square root of 5 and length of segment AC is 2 multiplied by the square root of 5 . Segment DE is half the length of segment AC. Substitution Property of Equality Slope of segment DE is −2 and slope of segment AC is −2. Slope Formula Segment DE is parallel to segment AC. Slopes of parallel lines are equal. Which is the missing justification? (6 points) a. Additive Identity b. Distance Formula c. Midsegment Theorem d. Transitive Property of Equality

After completing a study, Orlando International Airport managers concluded that the time needed to get passengers loaded on an airplane is normally distributed with a mean equal to 22.5 minutes and a standard deviation equal to 5.25 minutes. Recently one airplane required 33 minutes to get passengers on board and ready for takeoff. Find the probability that a flight will take 33 or more minutes to get passengers loaded.

Two pulleys, one with radius 3 inches and one with radius 6 inches, are connected by a belt. If the 3 dash inch pulley is caused to rotate at 4 revolutions per minute, determine the revolutions per minute of the 6 dash inch pulley. (Hint: The linear speeds of the pulleys are the same, both equal the speed of the belt.)

In a random sample of fivefive microwave ovens, the mean repair cost was $75.0075.00 and the standard deviation was $13.0013.00. Assume the population is normally distributed and use a t-distribution to construct a 9090% confidence interval for the population mean muμ. What is the margin of error of muμ? Interpret the results.

Please help The steps in writing f(x) = 18x + 3x2 in vertex form are shown, but a value is missing in the last step. Write the function in standard form. f(x) = 3x2 + 18x Factor a out of the first two terms. f(x) = 3(x2 + 6x) Form a perfect square trinomial. f(x) = 3(x2 + 6x + 9) – 3(9) Write the trinomial as a binomial squared. f(x) = 3(x + ______)2 – 27 What is the missing value in the last step?
