Answers
Answer:
manufacturer produces two different models; X and Y, of the same product .The raw materials r1 and r2 are required for production. At least 18 Kg of r1 and 12 Kg of r2 must be used daily. Almost at most 34 hours of labor are to be utilized .2Kg of r1 are needed for each model X and 1Kg of r1 for each model Y. For each model of X and Y, 1Kg of r2 is required. It needs 3 hours to manufacture model X and 2 hours to manufacture model Y. The profit realized is $50 per unit from model X and $30 per unit from model Y. How many units of each model should be produced tomportance of commerce.

a) r = 0.30
There is a high direct association between measures of ‘cigarettes smoking’ and ‘lung damage’. The correlation coefficient consistent .
- Measuring "cigarette smoking" and "lung damage" directly is highly correlated. The preceding statement has a correlation coefficient of *2 points. a) r = 0.30. The correlation's numerical value serves as a barometer for the consistency of the relationship.
- A correlation of 1.00 is considered to be ideal and denotes a relationship that is entirely consistent. Each change in X is preceded by a completely predicted change in Y when the correlation is 1.00 (or -1.0).
- Two variables that tend to move in the same direction are said to have a positive correlation. When one variable tends to go down as the other goes down or when one variable tends to go up as the other goes up, there is a positive connection.
- Correlation coefficients typically fall between -1.00 and +1.00. The strongest connection is taken into account when the value is closest to +1 (positive correlation) or -1, in accordance with the rule of correlation coefficients (negative correlation).
