1400/100= 14
Step-by-step explanation:
The slope of tangent line at a max or a minimum is 0,.
So using point slope formula.
Is the equation of a tangent line. This means we have a horizontal line at y= 4. Horizontal lines have a slope of 0.
To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.
