If all 22 tables had 6 people, there would be 132 people seated. There are 13 more than that, so 13 tables have 7 people.
Answer: The table and figure are given below,
Solution:
The given equation is 
.
put x=0 in the equation.
Similarly find the values of y at different values of x. The values are shown in the table.
From table it is notices that the value of y=-2 for x=0, y=-1 for x=3, y==-3 for x=-3, y=0 for x=6.
Plot these points in the coordinate plane and joint them by a straight line.
The gra his shown in below figure.
Make a rectangle that is 10 squares by 10 squares and color in 11 squares.
I think the correct answer would be the second option. Given the data above, the type of association that the scatter plot would show would be a positive linear association. It is best if you plot these points so you will see that there is an almost linear relation of the points. By doing linear regression, you can validate that the correlation of the data points would be linear. A positive linear association would mean that it changes linearly from the left increasing to the right. So, most likely, the graph would be sloping up to the right and it can be observed for the given data above.
Factor the equation into...
(3b+5)(3b+5)=0
Each factor 3b+5=0 so 3b=-5 so b=-5/3
Check:
9(-5/3)^2+30(-5/3)+25=
9(25/9)-50+25=
25-50+25=0
It checks,
So answer is A.-5/3
