The formula for converting Celsius temperatures into Fahrenheit temperatures is a linear equation. Water freezes at 0 degrees Celsius, or 32 degrees Fahrenheit, and it boils at a hundred degrees Celsius, or 212 degrees Fahrenheit. Find the slope and the y-intercept for a graph that gives degrees Celsius on the horizontal axis in degrees Fahrenheit on a vertical axis then write an equation in slope-intercept form that converts degrees Celsius into degrees Fahrenheit.

What is the equation of the graph below? y=sec(x)-4

which of the following sets of data would produce the largest value for an independent-measures t statistic? the two sample means are 10 and 20 with variances of 20 and 25 the two sample means are 10 and 20 with variances of 120 and 125 the two sample means are 10 and 12 with sample variances of 20 and 25 the two sample means are 10 and 12 with variances of 120 and 125

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
