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.
Answer:
The system has one solution.
Step-by-step explanation:
To find the number of solutions of the system, we equal both equations for y.
If we have ax = b, in which both a and b are different of 0, we have one solution.
If both a and b are 0, we have infinite solutions.
If a is 0 and b is not, there are no solutions.
y=6/7x-8 and y=7/9x+10/9
So
Both a and b are different of 0, so the system has one solution.
