Answer:
D. 189 is a good estimate.
Step-by-step explanation:
Fred has a spinner that is split into four equal sections: red, blue, green, and yellow.
This means each color has 1/4 chances to appear.
Fred spun the spinner 688 times.
So, a good estimate of the number of times the spinner lands on the green section will be =
We can say option D is closest.

y = - 3
Since y varies directly as x then
y = kx ← ( k is the constant of variation )
to find k use y = - 1 when x = 3
k = =
= -
hence y = - x
when x = 9, then
y = - × 9 = - 3
