Answer:
x-y =2 …(1)
x+y = 4 …(2)
add (1) and (2), to get
2x = 6, or x = 3. From (1) y = 3–2 = 1.
So x = 3, y = 1.
Answer:
Option C.
Step-by-step explanation:
In the given data minimum value is 0.5 and maximum value is 6.5.
In option A and D, last interval is 4-6. It means 6.5 is not included in these histograms. So, option A and D are incorrect.
Now,
Class interval Students Number of students
0-3 B,C,D,F,G,J,K,L,M,N,O 11
3-6 E,H,I 3
6-9 A 1
Histogram plots number of hours spent listening to music daily on x axis and number of students on y axis. Height of the bar in the x interval 0 to 3 is 11, height of the bar in the x interval 3 to 6 is 3, and the height of the bar in the x interval 6 to 9 is 1.
Therefore, the correct option is C.
The answer is 74. The parenthesis is another way of telling you to multiply.
