The graph shows p > 2. There is no line under the "greater than" sign since we want to exclude the endpoint p = 2. This is what the open hole indicates.

Solve each of the answer choices to see which leads to p > 2

----------------
Choice A
5p+4 > 14
5p+4-4 > 14-4
5p > 10
5p/5 > 10/5
p > 2

So we found the answer on the first try. 

Let's check the others
----------------
Choice B

This will follow the same exact steps as choice A above, but instead we'll have an underline under each "greater than" sign. As explained above, there is no underline. So we can rule out choice B.
----------------
Choice C

5p-4 > 14
5p-4+4 > 14+4
5p > 18
5p/5 > 18/5
p > 3.6

We can eliminate choice C
----------------
Choice D

-5p+4 > 14
-5p+4-4 > 14-4
-5p > 10
-5p/(-5) < 10/(-5) ... inequality sign flips
p < -2 

We can eliminate choice D
----------------

So the only answer is choice A

Olin [163]

Answer:

Option D. -0.901

Step-by-step explanation:

we know that

<u>The correlation coefficient</u> r measures the strength and direction of a linear relationship between two variables. The value of r is always between +1 and –1

Using a Excel tool (Correl function)

The value of coefficient r is -0.9006876

Round to three decimal places

r=-0.901

What is the value of y if (4y + 8) - (7t - 12) = 11?
Sunny_sXe [5.5K]
If the '7t' is supposed to be '7y', then the answer is below
(4y+8)-(7y-12)=11
distribute the negative into the second parenthesis
4y+8-7y+12=11
combine like terms
-3y+20=11
subtract the 20 from both sides
-3y=-9
divide by -3 on both sides
y=3

if it is supposed to be '7t', I'm not sure if there's enough information
