At the 0.05 significance level, what percentage of the samples will lead to a Type I error? These are sample proportions that would lead us to reject the null hypothesis and conclude the coin is weighted (unfair), even though the coin is actually a fair coin. 1%

An equation of the line tangent to y=x^3+3x^2+2 at its point of inflection is

Part a: sam rented a boat at $225 for 2 days. if he rents the same boat for 5 days, he has to pay a total rent of $480. write an equation in the standard form to represent the total rent (y) that sam has to pay for renting the boat for x days. (4 points)

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
