Answer:
a) We need to find p(x<68.15)
Standardize x to z, we have, z = (68.15-μ)/σ
=(68.15-57)/8.1
=1.38
Reading from standard normal tables,
p(z<1.38) =0.9162.
b) We need to find p(x>54.4)
Standardize x to z, we have, z = (54.4-μ)/σ
=(54.4-57)/8.1
=-0.32
Reading from standard normal tables,
p(z>-0.32) = 0.6255
b. i hope thats the right answer and works
Prepositional phrases express position and relation in space and time and begin with a preposition. The only prepositional phrases here are 1) "in the house," 2) "through the tunnel," and 3) "in 45 minutes." So, whichever of these are underlined in the problem, the corresponding sentences are the answers. Hope that helps!
