An article in knee surgery sports traumatology, arthroscopy, "effect of provider volume on resource utilization for surgical procedures," (2005, vol. 13, pp. 273–279) showed a mean time of 111 minutes and a standard deviation of 16 minutes for acl reconstruction surgery for high-volume hospitals (with more than 300 such surgeries per year).
a. if a high-volume hospital needs to schedule 10 surgeries, what is the mean and variance of the total time to complete these surgeries? assume the times of the surgeries are independent and normally distributed. mean = ? minutes and variance = ?

sine

step-by-step explanation:

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

c) yes, because of asa or aas

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
