the table shows the number of calories in four meals and the cost of each meal. which best describes the strength of the model? cost of meal and number of calories number of calories in the meal cost of the meal 550 $12 1,250 $11 780 $13 650 $10 a weak positive correlation a strong positive correlation a weak negative correlation a strong negative correlation

Answer

Explanation:

Step1: Observe data trends

As the number of calories increases from 550 to 1250, the cost goes from $11 to $13, but then at 780 calories the cost is $13 and at 650 calories the cost is $10. There is no clear - cut increasing or decreasing pattern.

Step2: Determine correlation type

Since there is no consistent increase or decrease in cost with an increase in calories, the correlation is weak. Also, there is no overall negative trend (as sometimes cost increases with calories), so it is a weak positive correlation.

Answer:

a weak positive correlation
