In a survey of 400 people ,160 people said they would rather have a cat instead of a dog .what percent of the people said they would rather have a cat?

Hi,

For this question, your answer would 40%.

All you had to was divide 160 by 400.

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.
