Investors are becoming more and amore concerned about the securities fraud, especially involving initial public offering. During the six-year period, the number of the number of federal securities-fraud class action suits has continued to increase: Year Suits 1996 110 1997 178 1998 236 1999 205 2000 211 2001 282 What is the slope of the best fitting line? a.26,514b.26.514 c.-52785 d.52785

Correct option is (a). 26.514

Step-by-step explanation:

The formula to compute the slope of regression line from raw data is:

Compute the values of ∑ XY, ∑ X , ∑ Y and ∑ X² as shown in the table.

The values are:

Compute the slope of the best fitting line as follows:

Thus, the slope of the best fitting line is 26.514.

The correct option is (a).

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
