Lesha and Maria spend the weekend studying for upcoming tests. The table lists their scores for the first three math tests of the semester. Part A Maria cannot remember what she scored on the second test, but she knows that the sum of the three tests is 270. Write AND solve an addition equation to determine the score that Maria had on her second test.

Part B An “A” grade will be given to students having at least 450 total test points. There are two more tests to take. Write AND solve an equation that will show the average score Lesha will need to have on the next two tests to finish with an “A”

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

care to share were the trapezoid shown is ?

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
