Answer:
At the U.S. Open Tennis Championship a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 95 miles per hour. Suppose that the statistician indicated that the serve speed distribution was skewed to the left. Which of the following values is most likely the value of the median serve speed? Explain your answer.

Step-by-step explanation:
step 1. perpendicular lines have negative reciprocal slopes
step 2. perpendicular to m = 1/3 is the slope m = -3/1 or m = -3
step 3. a line through (3, 2) with m = -3 is y - 2 = -3(x - 3)
step 4. y - 2 = -3x + 9
step 5. y = -3x + 11.
$0.85
38.25/45= .85
TO CHECK
.85 times 45 equals 38.25
Answer:
Dan=6 days Dave=12 days
Step-by-step explanation:
1/2x + 1/x = 1/4
multiply each by 8x bc 4 * 2x = 8x
4 + 8 = 2x
12 = 2x
6 = x
