WRITE EQUATION OF THE LINE PASSING THROUGH THE POINTS (5,4) AND (-6.3) Y=

Answers

Answer 1
Answer: First you have to find the slope of the line.  
(y2 -y1) / (x2 - x1) = slope
 so (3 - 4) / ( -6 - 5)  = -1/ -11 so the slope of the line is 1/11

Now you write y = mx + b  then substitute in one of the points with x and y
                     4 = (1/11)(5) + b
                     4 = 5/11 + b 
                 -5/11= - 5/11       change the 4 into 44/ 11 and subtract
     44 / 11 - 5/11=         b
                39/11 =     b                          now it depends on your teacher and text
usually, you can substitute the fraction for your b
     y = mx + b
     y = 1/11 x + 39/11   so this is your answer

Does that make sense or did I make a mathematical error?

Answer 2
Answer: ( x - 5) / ( -6 - 5) = (y - 4)/( 3 - 4) <=>  (x-5)/(-11) = (y-4)/(-1) <=> x - 5 = 11y - 44 <=>
 x - 11y + 39 = 0;

A junior college is going to choose a Homecoming Queen, and the candidates are the Freshman Queen and the Sophomore Queen. If there are 600 freshman and 400 sophomore voters, which would be a FAIR way of conducting the vote? [Fair, in this case, means that the Freshman Queen does not have an automatic advantage.]A) Count the votes, then deduct 100 from the freshman total.
B) Count the votes and the Queen with the highest total becomes Homecoming Queen.
C) Count the votes, counting each sophomore ballot as 1.5 votes and each freshman ballot as 1 vote.
D) Count the votes, counting each freshman ballot as 1.5 votes and each sophomore ballot as 1 vote.

Answers

count the votes, counting each sophomore ballot as 1.5 votes and each freshmen ballot as 1 vote.
ur doing this because there is 200 more freshmen then sophomores...and if u count each sophomore vote as 1.5, it would make up for the 200 more freshmen

The difference between an observational study and an experiment is thatA . in an observational study, only one group is studied, and in an experiment, two groups are studied.

B . in an observational study, the researchers do not control treatment, and in an experiment, they do.

C . in an experiment, cause-and-effect is analyzed, and in an observational study, it is not.

D . in an experiment, one group is studied over a short period of time, and in an observational study, the group is studied over a longer period of time.

Answers

Answer: (b) in an observational study, the researchers do not control treatment, and in experiment, they do.

Step-by-step explanation: In an observational study, only one group is studied, but in an experiment, more than one, may be two, three, etc. are studied, so option (A) is not correct. In an observational study, researchers control treatment but in experiment they do not, and so, option (B) is also incorrect. Option (D) is not correct, because a group is studied over a longer period of time in an experiment and the group is studied over a short period of time in observational study. The only correct option is (C) because cause and effect is studied in an experiment and are not studied in an observational study.

Hence, (C) is the correct option.
