HELP 10 POINTS and brainliest! What is the value of X? △MAH∼△WCF .

Mathematics
1 answer:
german3 years ago
4 0
The value of x is 23.

Simply find the scale factor or what was used to dilate △MAH to produce △WCF.

Use the equation copy over the original,

k = \frac{c}{o} = \frac{15.5}{62}

Reduce,

\frac{15.5}{62} = \frac{1}{4} = 0.25

So our scale factor is ¼ or 0.25

So if we use it and multiply the corresponding side of the missing side with the original we get,

92 \times \frac{1}{4} = 23

Therefore 23 is our missing side! !

~~

I hope that helps you out!!

Any more questions, please feel free to ask me and I will gladly help you out!!

Select strong association, weak association, or moderate association to correctly classify the correlation coefficient.
11Alexandr11 [23.1K]
Answers:


0.45 is a moderate association

0.95 and -0.8 are both strong association

0.10 is weak association


Explanation:


This is the interpreation of the correltaion coefficient:

1) The correlaion coefficient assesses the relationship between two variables in a scatter plot.


2) If the sign of the correlation coefficient is positive means that the two variables trend to grow or decrease in the same sense. This is an uphill line or curve:  if variable X grows, variable Y grows, and if variable X decreases variable Y grows.

If the sign of the correlation coefficient is negative means that the two variables go in opposite direction. This is a downhill line or curve.


3) A correlation coefficient of +1 or -1 is a perfect association. The two variables are totally associated.


4) A correlation coefficient less that +1 but greater than 0.7 is a strong association. The same with a coefficite between - 0.7 and -1.


5) A correlation coefficient arroun +0.5 or -0.5 is a moderate association.


6) A correlation coefficient of 0 is a nill association.


7) A correlation coeffiicient between 0 and 0.3 is a weak association. The same when the correlation coefficient is between -3 and 0.
