There are 6 questions, half of six is 3
So we're looking for how many students got more than 3 correct
in the 4 column there are 3, in the 5th column 4, and in the 6th column there are also 4
So now we have to add up how many got more than half together
3+4+4=11
11 students got more than half correct, so your answer is B
Answer:
B
Step-by-step explanation:
Corret on A P E X
(5x7)-9 Thisis because product means multiply "Of" mean sa smaller equation. therefor you need the (...) then 9 less than is minus but it has to go after the product since it's subtraction
Answer:
It is going to be bell-shaped(normally distributed), with mean 
and standard deviation 
.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
What can we say about the shape of the distribution of the sample mean time?
It is going to be bell-shaped(normally distributed), with mean and standard deviation .
Please, use the symbol " ^ " to denote exponentiation. At first I had no idea what you meant by 3r2.
You are using the approx. formula A = 3 r^2 to find the area.
The given radius is 4.3 inches. Subst. this value for r in the above equation.
Find A (keeping in mind that it's an approximation).
