Answer: The graph y = 18
+ mx + 2 will have only one intercept when m = 12 or m = -12.
Explanation:
A mass movement of funds invested in the stock market could result in a stock market crash such as that of 1929.
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
