Answer:
68 %
Step-by-step explanation:
Since we have our mean x = 250 and standard deviation σ = 20, we need to find how many standard deviations away the values 230 and 270 are.
Note x - σ = 250 - 20 = 230 and x + σ = 250 + 20 = 270
The values are one standard deviation away.
So, the values between 230 and 270 lie in the range x - σ to x + σ.
Since the batting averages are approximately normally distributed and for a normal distribution, 68 % of the values lie in the range x - σ to x + σ.
So, 68 % of Braves players fall between 230 and 270.
Answer:
p=5i
Step-by-step explanation:
(p^(4)=-25p^(2))/p^(2)
p^(2)=-25
Square root both sides
p=5i
i is the square root of -1, so 5i is five times that much.
The square root of a negative number in not real. That is why it is i, and not a number.
