Out of 17 boys and 13 girls of a class, one student is to be selected. What is the probability of selecting a girl

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

its a straight line parallel to the time axis

25% is the answer

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.
