Answer:
Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.
Step-by-step explanation:
We use the central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a sample size larger than 30 can be approximated to a normal distribution with mean and standard deviation 
So
Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.
Let's take a look at a perfect square trinomial.
We can distribute this expression to get
.
An important relation to recognize here is that the constant is the square of half of the x value.
Now, if we wanted to add a number to
to make a perfect square trinomial, we could have the value of x and then square it.
Half of 16 is 8, and 8 squared is
Answer:
379.94
Step-by-step explanation:
11 squared is 122
Times 3.14 is 379.94
THE ANSWER IS GREATER THAN I TOOK THIS LESSON!
Answer:
y-9 = (-3/2)(x+8)
Step-by-step explanation:
point slope form: given (a,b) and slope m the equation is
y-b = m(x-a)
now just plug you given points in
y-9 = (-3/2)(x+8)
