The value of a correlation coefficient ranges between -1 and 1.
The greater the absolute value of the Pearson product-moment correlation coefficient, the stronger the linearrelationship.
The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.
The weakest linear relationship is indicated by a correlation coefficient equal to 0.
A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
therefore
d is correct
-0.9
Answer:
Step-by-step explanation:
You need to pay very close attention to the triangle similarity statement. This says that triangle NML is similar to triangle NVU. But if you look at the way that triangle NVU is oriented in its appearance, it's laying on its side. We need to set it upright so that angle N is the vertex angle, angle V is the base angle on the left, and angle U is the base angle on the right. When we do that we see that sides NV and NM are corresponding and exist in a ratio to one another; likewise with sides VU and ML. Setting up the proportion:
Filling in:
Cross multiply to get
324 = 108x
and x = 3
Answer: y=1
Step-by-step explanation:
First we need to get y alone.
y+3 = 4
We must subtract 3 on both sides (this will cancel out the +3 on the y side).
y=1
If you had y-3=4 then you would have to add 3 on both sides to cancel out the -3 on the y side.
If it is division you multiply and vise versa. Just do the opposite to everything on the y side to give y alone and figure out what y is equal to!
:) Best of luck!
-23 3/4
the reason why its negative because its below sea level

Answer:
6.8
Step-by-step explanation:
To round 6.752 to the nearest tenth consider the hundredths’ value of 6.752, which is 5 and equal or more than 5. Therefore, the tenths value of 6.752 increases by 1 to 8.
