Graph a triangle (STU) and reflect it over the y-axis to create triangle STU'. 1. Describe the transformation using words. Make sure you refer to the characteristics and the coordinates.
2. Draw a line segment from point S to the reflecting line, and then draw a line segment from point S' to the reflecting line. What
do you notice about the two line segments you drew? Do you think you would notice the same characteristics if you drew the
line segment connecting T with the reflecting line and then t' with the reflecting line? How do you know?

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?

Arecent study focused on the number of times men and women who live alone buy take-out dinner in a month. assume that the distributions follow the normal probability distribution and the population standard deviations are equal. the information is summarized below. statistic men women sample mean 24.85 21.33 sample standard deviation 5.54 4.93 sample size 34 36 at the 0.01 significance level, is there a difference in the mean number of times men and women order take-out dinners in a month? state the decision rule for 0.01 significance level: h0: μmen= μwomen h1: μmen ≠ μwomen. (negative amounts should be indicated by a minus sign. round your answers to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? what is the p-value? (round your answer to 3 decimal places.)

Using the rise/run counting method, the slope of the line is
