The melting points of two alloys are being compared. thirty-five specimens of alloy 1 were melted. the average melting temperature was 517.0◦f and the standard deviation was 2.4◦f. forty-seven specimens of alloy 2 were melted. the average melting temperaturewas510.1◦2.1◦f. find a 99% confidence interval for the difference between the melting points.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":
