Answer:
The margin of error for this estimate is of 14.79 yards per game.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
T interval
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 20 - 1 = 19
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of 
. So we have T = 2.093
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
You randomly select 20 games and see that the average yards per game is 273.7 with a standard deviation of 31.64 yards.
This means that 
What is the margin of error for this estimate?
The margin of error for this estimate is of 14.79 yards per game.
Answer:
The solution is 
.
Step-by-step explanation:
A first order differential equation 
is called a separable equation if the function 
can be factored into the product of two functions of 
and 
:
where 
and 
are continuous functions.
We have the following differential equation
In the given case 
and 
.
We divide the equation by and move 
to the right side:
Next, integrate both sides:
Now, we solve for
We use the initial condition 
to find the value of C.
Therefore,
8.333333 reoccurring. 1 divided into 6 is 1.666667. Multiply by the remaining amount, 5? Idk
