Suppose that the weights of jars of jelly are normally distributed with a mean of 10.2 ounces and a standard deviation of 0.10 ounces a. What percentage of the jars of jelly would you expect to weigh less than 10.15 ounces?

b. What percentage of the jars of jelly would you expect to weigh more than 10.15 ounces?

c. What percentage of the jars of jelly would you expect to weigh between 10.15 and 10.35 ounces?

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
