x = ±
i
rearrange the equation and equate to zero
2x² - 6x = - 5 ⇒ 2x² - 6x + 5 = 0
this doesn't factor with integers, hence use the quadratic formula to solve
with a = 2, b = - 6 and c = 5
x = (6 ± √(36 - 40 ) )/4
= (6 ± √(-4) ) / 4
= (6 ± 2i ) / 4
x = ±
i
Answer:
0.625
Explanation:
The image below was not posted for the but is needed to anser the question.
Further Explanation:
Mohamed carried out 24 trials of a simulation
Therefore, Total frequencies = 24
To get number of frequency greater than 3 we have to use the result in the result in the graph to obtain the estimate. Look at the graph below, when you count the dots that are on number of boxes purchased greater than 3, you will get 15.
Therefore, Number of frequency greater than 3 = 15
P(more than 3 boxes) = 15/24 = 0.625
