Atank has an opening through which water leaks out. the table below shows the amount of water, in gallons, in the tank after different amounts of time, in hours:
what type of association will the scatter plot for this data represent between the number of hours and the amount of water in the tank, in gallons?
a negative nonlinear association
a positive linear association
a positive nonlinear association
a negative linear association

A negative linear association

Step-by-step explanation:

From the given table in the picture , it can be seen that as the time is increasing the amount of water in tank decreases, it indicates that there is a negative association between the two variables.

Also, the rate of change in amount of water is constant as 0.5 gallon per hour.

It implies there is a linear association.

Now, the scatter plot for this data represents there is a negative linear association between the number of hours and the amount of water in the tank, in gallons.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
