The mean number of fielding errors committed by a major league second baseman in a season is normally distributed about a mean of 7 with a standard deviation of 1. For a third baseman, the mean is 10 with a standard deviation of 2. If the second baseman for the Yankees commits 8 errors in a season and the Blue Jays third baseman committed 13, who is the better fielder? Justify your answer.

step-by-step explanation:

not really sure

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

what is the question?
