Class A: 3 out of 30 = 3 / 30 = 0.1 = 10%
Class B: 28 out of 40 = 28 /40 = 0.7 = 70%
Class C: 11 out of 28 = 11 / 28 = 0.39 = 39%
Class D: 14 out of 50 = 14 / 50 = 0.28 = 28%
The answer is Class D
Answer:
Distance = 0.5
Step-by-step explanation:
A(2.7 , 5.1) B(3 , 4.7)
D = √((4.7 - 5.1)² + (3 - 2.7)²)
D = √(12² + 5²)
D = 0.5
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.
It looks like this.
Only 1 of the 3 rectangles that's inside is shaded in. So that would be 1/3 of the rectangle
