Answer/Step-by-step Explanation:

A. From the scatter plot attached below showing the number of flowers that have bloomed for days in the month of March, we can observe an upward trend which shows a positive correlation , and also, if we are to draw a single line in an attempt to connect the points together on a straight line as much as possible, we'd discover that the points are not far away from the single line. This implies not only a positive correlation coefficient, but also a correlation coefficient that is closer to 1. Hence, we can infer that correlation coefficient of r = 0.98 is accurate because of the aforementioned reasons. The trend denotes a string positive correlation.

B. A scenario that would be a causal relationship for flowers in a garden to bloom is the length of daylight received each day by the flowers. Length of daylight could be a factor influencing flower bloom. Or we can also make a scenario of comparing amount of fertilizer for flower development given to plants in comparison to the number of flowers.

Answer:

The area of the building in terms of y in its simplest form is 12(y + 2)

Step-by-step explanation:

Since the area of a rectangle is A = LW where L = length and W = width. From our question, the width of the rectangular building is 3 feet. So, W = 3 feet and its length is 4y + 8 feet. So, L = 4y + 8 feet.

So, the area of the building in terms of y is A = LW

= (4y + 8) × 3

Factorizing out 4 from the expression, we have

= 4(y + 2) × 3

= 12(y + 2)

So, the area of the building in terms of y in its simplest form is 12(y + 2)
