During a routine check of the fluoride content of gotham city's water supply, the given results were obtained from replicate analyses of a single sample: 0.91500 mg/l , 0.88900 mg/l , 0.91100 mg/l , 0.88900 mg/l , and 0.91900 mg/l . determine the mean and 90% confidence interval for the average fluoride concentration in this sample. report the mean and the confidence interval with three significant figures. mean: 0.905 mg/l 90% confidence interval: ± 0.0124 mg/l

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.

mean, 40.6

step-by-step explanation:

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.
