Choose the answer. 3. (1 pt) for the data shown in the stem-and-leaf plot, what is the effect on the mean and median of adding the value 30 to the data set?
a. the mean is increased by about 0.4 and the median is increased by 3.
b. the mean is increased by about 0.4 and the median is increased by 4.
c. the mean is increased by about 0.6 and the median is increased by 3.
d. the mean is increased by about 0.6 and the median is increased by 4.

Based on the question, there's no stem-and-leaf plot being presented. Nevertheless, giving you the technique, before adding 30 to the data, get the mean and the median. After that, 30 to the data. Then, get the mean and the median. Compare it.

Part A: f(w) = 3(15w) +35

Part B: f(w) represents the total number of flowers that bloomed after w weeks.

Part C: 1655

Step-by-step explanation:

Part A: combine the f(s) and s(w). Since s is the common variable we substitute to s(w) = 15w for s in the function f(s) = 3s = 35. So, the new function is 3(15w) + 35. We can combine the function notation to be f(s(w)) or we can create a new function notation, like f(w). So f(w) = 3(15w) + 35

Part B: f(w) represents the total number of flowers that bloomed after w weeks. This is pretty self-explanatory.

Part C: plug in 36 for w. f(w) = 3(15*36) + 35. f(w) = 1655
