Answer:

It states that time spent on social networking sites & twitter have a strong positive correlation.

Step-by-step explanation:

Correlation is the statistical measure of co-movement relationship between two variables. Correlation Coefficient 'r' lies between -1 & +1

Correlation can be following on basis of variables relationship direction

  • Positive Correlation : It means two variables move in the same direction - one variable increase, other variable increase & one variable decrease, other variable decrease. 'r' is positive.
  • Negative Correlation : It means two variables move in opposite direction - one variable increase, other variable decrease & one variable decrease, other variable increase. 'r' is negative.

Correlation can be following on the basis of variables :

  • Strong Correlation : It means the variables fluctuations are more inter-related. r > 0.5
  • Weak Correlation : It means the variables fluctuations are less inter-related. r < 0.5

Correlation between times spent on social networking sites & twitter is 0.8 This r = 0.8 means that the two activities have strong positive correlation. It implies that increase in one lead to increase in other activity & vice versa, by a high magnitude.

Sum of exterior angles in a equilateral triangle
poizon [28]

Answer:

In the case of the equilateral triangle, , the exterior angle, plus 60 equals 180. Subtracting 60 from both sides of this equation gives us a value of equal to 120. This means that the exterior angle of an equilateral triangle is equal to 120 degrees. The sum of all the exterior angles is always 360 degrees.

The sum of two numbers is 64 and their differences in 10. Find the numbers
uranmaximum [27]

Answer:

37 and 27

Step-by-step explanation:

Lets say that the two numbers are x and y. We get the equations x + y = 64 and x - y = 10. We can then add these two equations together to get, 2x = 74. Then we divide by two on both sides and get x = 37. We then plug this value back into the second equation and get that 37 - y = 10. We can simplify this and we get that y = 27. So our two numbers are 37 and 27.

15 points: can someone help me with this thank you. (all separate equations)
OLga [1]

Step-by-step explanation:

6x+3y=12\qquad\text{subtract}\ 6x\ \text{from both sides}\\\\6x-6x+3y=12-6x\\\\3y=12-6x\qquad\text{divide both sides by 3}\\\\\dfrac{3y}{3}=\dfrac{12}{3}-\dfrac{6y}{3}\\\\\large\boxed{y=4-2y}\\\\===================

2p-k=3\qquad\text{subtract}\ 2p\ \text{from both sides}\\\\2p-2p-k=3-2p\\\\-k=3-2p\qquad\text{change the signs}\\\\k=-3+2p\\\\\large\boxed{k=2p-3}\\\\===================

6v-2w=10\qquad\text{subtract}\ 6v\ \text{from both sides}\\\\6v-6v-2w=10\\\\-2w=10-6v\qquad\text{divide both sides by (-2)}\\\\\dfrac{-2w}{-2}=\dfrac{10}{-2}-\dfrac{6v}{-2}\\\\w=-5+3v\\\\\large\boxed{w=3v-5}\\\\===================
