This is relatively easy because that 25 is a perfect square, whose (square) roots are 5 and -5. x^2-10x+25 = (x - 5)(x - 5). Note how (-5)(-5) = +25, and how -5x - 5x = -10x.
The roots are { (x-5), (x-5) }.
Maybe 50 meters I’m not sure
Answer:
4ft, 7 inches
Step-by-step explanation:
4 ft (48 inches), 7 inches
Cotxcos2x = 2cotx
cos2x = 2cotx/cotx
cos2x = 2
cos2x = 2cos²x - 1
2cos²x - 1 = 2
2cos²x = 2+1
2cos²x = 3
cos²x = 3/2
√cos²x = plus minus √(3/2)
cosx = plus minus √(3/2)
Answer: There is a high data value that causes the data set to be asymmetrical for the males.
The females 'might' have an outlier, but it's difficult to say exactly.
An outlier is defined as any data value greater than 1.5 times the Interquartile range or less.
