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
see the table attached
Answer:
The answer is 4!!
Step-by-step explanation:
A Passport picture is normally in the rectangular formation meaning, if the width of the top of the passport picture is 3, then the bottom is 3 as well.
That lets you figure out, since perimeter is all sides added together, 3+3 = 6 so 6 is both widths combine.
With this 6 in mind, if the perimeter of the entire passport is 14cm, and you have 6cm as both widths combine, now you need to find the length of this object.
Now here, since 6 is both widths combined, simply here you do 14cm - 6cm which is 8.
8 is the total length, meaning both sides added. See now that is the answer if you are finding out the total length (which is ha not the question).
Since you are trying to find only 1 side of the length, since there are 2 sides, you do 8 divided by 2, and BAM you get which is actually your answer as well!
PS. I don't even know if this is right though it should be right, use a calculator if you are doubtful :D
Happy New year!
The answer is A I believe
