Answer:
In Grade 8, 22% of students liked volleyball.
Step-by-step explanation:
Given:
The table representing the relative frequencies of different sports in different grades among the students.
Swimming Running Volleyball Row totals
Grade 8 0.14 0.18 0.22 0.54
Grade 9 0.17 0.24 0.05 0.46
Column totals 0.31 0.42 0.27 1
Relative frequency gives the ratio of the number of quantities of a particular kind and the total number of quantities.
From the above table, we can conclude the following points:
Grade 8:
14% liked swimming, 18% liked running and 22% liked volleyball. So, a total of 54% students liked playing sports.
Grade 9:
17% liked swimming, 24% liked running and 5% liked volleyball. So, a total of 46% students liked playing sports.
Combining students of grade 8 and 9:
31% liked swimming, 42% liked running and 27% liked volleyball.
From all the options available, we observe that, third option is only correct.
In Grade 8, 22% of students liked volleyball.

H ( 6, 4 ) and K ( 2, 8 ):
x 1 = 6, x 2 = 2;
y 1 = 4, y 2 = 8:
x m = ( 6 + 2 ) / 2 = 8 / 2 = 4
y m = ( 4 + 8 ) / 2 = 12 / 2 = 6
Answer: D ) ( 4, 6 )
Answers
t= 20/x seconds
b) d=25m
s= x+0.5 m/s
t= d/s = 25/x+0.5
c) total time = 6 seconds
therefore, 20/x + 25/x+0.5 = 6
make a common denominator of x(x+0.5):
(20(x+0.5) + 25x)/x(x+0.5) = 6
move the demoninator to the other side, and expand to form:
20x+10+25x = 6x(x+0.5)
45x+10= 6x^2 +3x
tidying it up (moving everything to one side)
6x^2 - 42x-10 = 0
divide everything by 2
3x^2-21x-5= 0 (as required)
d) use quadratic formula to solve
e) therefore, what does x equal?
hope this helps
