This question is incomplete.
The complete question says;
The two-way table shows the number of hours students studied and whether they studied independently or with a study group.
What is the relative frequency of students that studied independently for more than 2 hours to the total number of students that studied independently?
a) 0.4 c) 0.25
b) 0.33 d) 0.11
Table is attached as image
Answer: C (0.25)
The number of students that studied for more than 2 hours as given in the table are 4.
The total number of people that studied independently include those that studied less than 2 hours and those that studied for more than 2 hours.
Those that studied less than 2 hours independently are 12.
Those that studied more than 2 hours independently are 4.
Hence the total number of people that studied independently is 16.
Therefore the relative frequency of students that studied independently for more than 2 hours to the total number of students that studied independently would be = 4/16 = 1/4 = 0.25.
Answer:
<h2>NONE OF THEM</h2>Step-by-step explanation:
From the graph,
y and x intercepts are and approximately
respectively
for A, C and D :
x intercept the value of y=0, and y intercept x=0.
x and y intercepts are and approximately
respectively
for B:
x and y intercepts are and approximately
respectively
Therefore x and y intercepts for the lines and
they are not equal to the x and y intercepts of the given graph
