RoseWind [281]

Answer:

(B) Slope increases, correlation increases

Step-by-step explanation:

The plot graph is having a positive correlation with all of the dots located near the line. The new tenth data is located in the bottom left, touching the right side of the line. Since the new data is very close to the line, the correlation will increase. The data is located on the right of the line so it will shift the line to the right. If the bottom part of the line shift to the right, the slope will become higher.

Name a number that can be evenly divided by 6 and and by 7
Alona [7]

There are an infinite number of them.  The smallest one is 42,
and every multiple of 42 is another one.

I don't remember the official correct way to solve this problem. 
I can only show you my own way of doing it.

I take the bigger number, and I go through its multiples, one by one,
until I spot one that's also a multiple of the smaller one.

Example:  6 and 7.
Go through the multiples of 7:

7 ... no, not a multiple of 6
14 ... no, not a multiple of 6
21 ... no, not a multiple of 6
28 ... no, not a multiple of 6
35 ... no, not a multiple of 6
<em><u>42</u></em> ... Yes !  A multiple of 6.  yay !

How many extraneous solutions does the equation below have?
FrozenT [24]

<u>Answer</u>

0


<u>Explanation</u>

(2m)/(2m+3)-(2m)/(2m-3)=1

Simplifying the left hand first

(2m)/(2m+3)-(2m)/(2m-3) = {2m(2m-3) - 2m(2m+3)}/(4m²-9)

                                        (4m²-6m-4m²-6m)/(4m²-9)

                                         = (-12m) / (4m²-9)

Now this equet to 1

(-12m) / (4m²-9) = 1

-12m =  4m²-9

4m²+ 12m -9 =0 ⇒⇒⇒ This is a quadratic equation that has 2 real solutions.

4m²+ 12m -9 =0

m² + 3m + (3/2)²= 9/4 + 9/4

(m + 3/2)² = 18/4

m = √18/2 - 3/2                or m = -√18/2 - 3/2

    = 0.621                                       = -3.621

So we can say that the equation has NO extraneous solutions.

Answer = 0
