A vendor sells h hotdogs and s sodas. If a hotdog costs twice as much as a soda, and if the vendor takes in a total of d dollars, how many cents does a soda cost?

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

yes. we do proportions in probabilities.

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.
