Answer:
The correct option is C) large sample size (n) with small variance.
Step-by-step explanation:
Consider the provided information.
It is given that the other factors are held constant, and we want the narrowest confidence interval for a population mean.
Confidence interval for a population mean is directly proportional to variance and inversely proportional to the sample size.
If we increase the variance, CI will increase. But we want the narrowest CI, so variance should be small.
As CI is inversely proportional to sample size, therefore if we increase the sample size CI will decrease.
Hence, the correct option is C) large sample size (n) with small variance.
#2 is 10x-y because 7x+3x=10xthen your subtracting 2y-y so it would be 10x-y
Well if the equation is -16t^2 + vt + h0,
and we know v = 30, because that's the velocity,
and we also know h0 = 6 because that's the height,
then the equation will read: -16t^2 + 30t + 6
Answer:
Option A - 
Step-by-step explanation:
Given : For the sequence 
To find : Identify the values of following?
Solution :
The nth term of the sequence is
Substitute n=0,1,2 and 3
When n=0,
When n=1,
When n=2,
When n=3,
Therefore, The value is
So, Option A is correct.
Using slope point form of equation:
(y-y1) = m(x-x1)
Given: A(1,5) which is in the form (x1,y1), and m= -8
substituting in the equation above:
(y-5)= -8(x-1)
y-5 = -8x+8
y=(-8x+13) <----Answer
which is in the form : y=mx+b (slope intercept form)
