Answer/Explanation:
A. Fom the dattached diagram below showing the number of flowers that have bloomed in the garden in the month of March, we can infer that the trend shows a strong positive correlation. If we attempt to draw a straight line to connect some of the points on the plot, we would realized that we're going to be having a line that slopes upward, and also points are either on the line or are at least not far from the line drawn. Having a correlation coefficient or r = 0.98, we can assume that value to be accurate because the trend shows a positive correlation that is closer to a correlation coefficient of 1.
B. A scenario that would show a casual relationship for flowers in the garden is the comparison of the numbers of flowers in the garden and the quantity, in kg of a nutrient-rich fertilizer.

I'm assuming that you mean
because if you meant
then u would simplify and you couldn't make it the subject.
Under this assumption, we start with
We multiply both sides by
We expand the left hand side:
We move all terms involving u to the left and all terms not involving u to the right:
We factor u on the left hand side:
We divide both sides by
3x²+x-5=0
a = 3, b = 1, c= -5
-> ∆ ( delta ) = b²-4ac = 61 > 0
-> x1 =( -b+√∆ )÷ 2a =...
x2 = (-b-√∆)÷2a =...
p/s: do your teachers teach you how to use ∆ ( delta ) in maths calculation ? i live in europe and our teachers teach us that way. however, it is a rịght and fast way. you should learn it.
