There are two answers :

In Grade 8, 17% of students liked running.

In Grade 9, 31% of students liked volleyball.

Step-by-step explanation:

We can convert decimal number to percent.

So 0.17*100= 17%

We just need to multiply by 100:

Grade 8: 24 %  17%   5% 46%

Grade 9: 42% 14% 22%    54%

From this we can see our answers.

In Grade 8, 17% of students liked running.

In Grade 9, 31% of students liked volleyball.

in grade 8 17% of students like running

Step-by-step explanation:

took  the test

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
