516+497+501+528+476= 2518
2518/5= 503.6
round up to 504
Answer:
A. The larger the sample size the better.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation 
In this question:
We have to look at the standard error, which is:
This means that an increase in the sample size reduces the standard error, and thus, the larger the sample size the better, and the correct answer is given by option a.
Answer:
the 4th it hits 10 after 2 seconds
Step-by-step explanation:
the ball starts at (6,0) feet/height 0 seconds, then is thrown, at the slope/ top is where the ball accelerated or went the highest is (10,2) ten feet, two seconds, and was able to stay in the air for 6 and ends at (0,6 1/8) 0 feet and 6 1/8 seconds, that is why the the slope curves down, showing that the ball has landed but this is not exactly 6 seconds. hope this helps
Answer:
The correct option is;
x = 1
Step-by-step explanation:
The parameters given are;
Location of circle center = 1 on the x axis
Radius of circle = 1
Required operation on circle = Revolving to create a sphere
To form a spherical shape by the rotation of a circular figure involves rotating the circular figure about a line passing through the center of the circle
Therefore, to form a sphere, the circle should be about a line that passes through x = 1
Hence, the circle should be rotated about the line x = 1.
To solve this problem, we make use of the formula:
y = a sqrt (b (x – h)) + k ---> 1
Since we are given the parent function:
y = sqrt (x) --->
2
Then this automatically means that:
a = 1 and k = 0
So going back to equation 1 at a = 1 and k = 0:
y = 1 sqrt (b (x – h))
Since it is given that, b = 4 and h = 1,
therefore:
y = sqrt (4 (x – 1))
y = sqrt (4 x – 4)
Answer:
A. y = sqrt (4 x – 4)
