Sonja [21]3 years ago

The correlation coefficient of a scatter plot with line of best fit shown will be the slope of the line.

We can eliminate last 2 choices because the line is clearly a downward sloping line and it's slope wont be positive.

From the first two, it looks like the plot's slope is very close to -1. So we take -0.91, instead of -0.35. <em>[note: 0.91 is more steeper than 0.35 (which is very relaxed)]</em>


ANSWER: -0.91

Vladimir79 [104]
You should get it now from my previous answer.

But to apply it.

9 - 8b + 6b
9 + (-8b + 6b)   <- Collect like bases (b)
9 + (-2b)           
9 - 2b

Therefore it simplified is 9 - 2b

The point (4,6) a nonviable solution The point (6,5) mola bouton of this system of this system.

Solution :

Total amount to be targeted by selling of popcorns in the movie theatre is 550,000.

A viable solution is one which has a definite meaning or definite solution to the question in context whereas a non viable solution does not have a definite relevant solution to the question.

In the context,

The point (4,6) is a non viable solution as it does not satisfy 1st inequality and only satisfies the second inequality.

The point (6,5) is a viable solution as it satisfies both the inequalities.
