A polynomial p is graphed. What could be the equation of p?
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :
X+y=3
x-y=21
x=3-y
3-y-y=21
-2y+3=21
-2y=18
y=-9
x = 3-(-9) = 12
Two numbers are 12 and -9.
Hope this helps.

That statement is only true sometimes. If you use 500 and 10, 10% of 500 is 50, while 20% of 10 is only 2. Clearly, 50 is larger than 2.
