Anumber n plus 7 is less than or equal to 9

So n + 7 less than or equal to 9. substract 7 from both sides. n less than or equal to 2. that's your answer

Part A. A correlation coefficient of r = 0.01 is not an accurate value for the data.Part B. A scenario that would be a causal relationship for strawberries picked on the farm, may have the conditions of the roads as the cause.

Explanation:

Part A.

A correlation coefficient of r = 0.01 is not an accurate value for the data on the scatter plot, because it is very close to 0, which means that the data are not linearly correlated, while the figure, on the contrary, shows that the data moderately follow a linear pattern.

A pattern as the one shown in the figure is closer to 0.5 (may be between 0.4 and 0.6).

When the data are perfectly linearly correlated r is equal to +1 (positive correlation) or - 1 (negative correlation). The minimum absolute value for r is 0 and it means that the data are not correlated at all. Hence, r = 0.01, being very close to 0, means that the data are not linearly correlated, which contradicts the graph.

Part B.

A causal relationship is when the independent variable not only is correlated with the dependent variable but it causes it.

Is the day the cause of the number of strawberrys picked? Hardly. It must be another third variable, which is somewhat associated with the day in February but not a 100%, and that is directly responsible for the number of strawberries picked.

What variable might it be? It could be the state of the road to the harvesting place.

That would be the case if the road is repaired and every day the road is a bit better, letting the workers arrive earlier to the place and spend more hours harveting.
