This is the formula you would use to calculate how many tiles you would need.
# of tiles you need = Total square footage ÷ square footage of each tile
Total square footage: 69x69 = 4761 square feet
Square footage of each tile = 2x2 = 4 square feet
# of tiles you need = 4761 ÷ 4 = 1190.25
You will need 1190.25 tiles.

In this question, we are asked to calculate the probability of selecting a sunflower greater than a particular height.
What to do in this case is to first find the z-score based on this information given.
Mathematically,
Z-score = x- mean/standard deviation
Here, z-score will have a value of;
(16.4-14.2)/2.15 = 1.023
Therefore,
P(height >16.4ft) = P(Zscore >1.023) = 1-Fz(1.023) = 0.153
89.25 is the original price first i did 75÷100=0.75×51=38.25+51=89.25 is the correct answer.
