The ratio of false positives to false negatives is (d) 3.5

<h3>How to determine the ratio?</h3>

The table of values is given as

                          Activates.   Does not activate Row Totals

Lightning in area     88%           2%                           90%

No lightning in area 7%             3%                           10%

Column Totals           95%          5%                          100%

The false negative is when there is lighting and it does not activate

So, we have

False negative = 2%

The false positive is when  there is no lighting and it activates

So, we have

False positive = 7%

When represented as ratio, we have

Ratio = 7% : 2%

So, we have

Ratio = 7 : 2

This gives

Ratio = 7/2

Evaluate

Ratio = 3.5

Hence, the ratio is (d) 3.5

AB and BC form a right angle at their point of intersection. This means AB is perpendicular to BC.

We are given the coordinates of points A and B, using which we can find the equation of the line for AB.

Slope of AB will be:

m= \frac{-1-1}{14-2}=-1/6

Using this slope and the point (2,1) we can write the equation for AB as:

y-1= \frac{-1}{6}(x-2) \\  \\ &#10;y= -\frac{1}{6}x+ \frac{1}{3}+1 \\  \\ &#10;y=-\frac{1}{6}x+ \frac{4}{3} &#10;

The above equation is in slope intercept form. Thus the y-intercept of AB is 4/3.

Slope of AB is -1/6, so slope of BC would be 6. Using the slope 6 and coordinates of the point B, we can write the equation of BC as:

y - 1 = 6(x - 2)
y = 6x - 12 + 1
y = 6x - 11

Point C lies on the line  y = 6x - 11. So if the y-coordinate of C is 13, we can write:

13 = 6x - 11
24 = 6x
x = 4

The x-coordinate of point C will be 4.

Therefore, the answers in correct order are:

4/3 ,  6,  -11,  4
