A marketing researcher is testing out new names for a hair product. She asks 40 women to pick the name of the product that they
would be most likely to buy out of a list of 4 names. Could she use a dotplot to describe her results?
1 answer:
Answer:
Yes, she can use a dotplot to describe her results.
Step-by-step explanation:
A dot-plot is a chart where each data is represented as a dot and it's values fall in discrete bins.
She can set a graph where 4 names of the product is represented on the horizontal axis and for each woman giving a name of the product, a dot is placed on top of the horizontal axis.
A sample dot-plot for this study is attached.

Answer:
Option (A)
Step-by-step explanation:
By satisfying the equation of a function 'f' by each coordinates given in the options we can get the point which lies on the graph of f(x) =
Option (A). (1, 10)
f(1) =
10 = 10
True.
Therefore, point (1, 10) lies on the graph.
Option (B). (0, 10)
f(0) =
10 = 2
Not true.
Therefore, point (0, 10) doesn't lie on the graph.
Option (C). (10, 1)
f(10) =
1 = 19531250
Not true.
Therefore, point (10, 1) doesn't lie on the graph.
Option (D). (0, 0)
f(0) =
0 = 2
Not True.
Point (0, 0) doesn't lie on the graph.
Option (A) will be the answer.
