You have to have a better question to answer that, 100 feet more what?
Answer:
The radius is given its 10 in
The diameter is 20 in
Step-by-step explanation:
Two find the diameter given the radius you just multiply by 2
10x2=20 therefore the diameter is 20
Hope this helps :)
Answer:
D)
, 
Step-by-step explanation:
The blue boundary line has a y-intercept of 2 and a slope of 2.
It has equation : 
Since the boundary line is not solid and the lower half plane of this line is shaded, its inequality is

The blue boundary line passes through the origin and has slope
.
Its equation is 
Since the boundary line is not solid and the right half-plane is shaded, its inequality is 
The correct choice is D.
The percentage of the runners who have times less than 14.4 sec is 0.15%
The times of all 15-year old who run a certain race are approximately normally distributed with a given mean of 18 sec and a standard deviation of 1.2 sec.
We know that,
where,
X = raw score = 14.4
μ = mean = 18
σ = standard deviation = 1.2
Putting the values,
Finding the probability from the z score table, we get
P(z < -3) = 0.00135 = 0.135%
