57.885
Step-by-step explanation:
For such calculations a probability calculator is very helpful. The one in the attachment shows the 87th percentile to be 57.885.
___
A table of the standard normal distribution will tell you the 87th percentile corresponds to a z-value of 1.12639. Then the X value is ...
X = Zσ +μ = 1.12639(7) +50 = 57.885
Answer:
X=-5 or X=1
Step-by-step explanation:
f(x)=(x+5)(x-1)
(x+5)(x-1)=0
x=-5 orx=1
Answer:
114
Step-by-step explanation:
