To solve this we use the z statistic. The formula for z
score is:
z = (x – u) / s
where x is the sample value = less than 16, u is the
sample mean = 16.1, s is standard dev = 0.1
z = (16 – 16.1) / 0.1
z = - 1
From the standard distribution tables at z = - 1,
P (z = -1) = 0.1587
<span>So about 15.87% is underweight.</span>

Answer: d = 1/5t
Step-by-step explanation:
Since it is a direct variation , Let d represent the distance and t represent the time ,then
d ∝ t
introducing the proportionality constant, we have
d = kt
Substituting t = 10 and d = 2 , we have
2 = 10k
k = 1/5
substitute k = 1/5 into the original equation , we have
d = 1/5t
Answer:
x<-16
Step-by-step explanation:
1/4x+6<2
1/4x<2-6
1/4x<-4
x<-4/(1/4)
x<-4(4/1)
x<-16/1
x<-16
