Answer:
Step-by-step explanation:
Formula
Sn = (a + a + (n - 1)*d) * n / 2
Givens
Sn = 60
a = 3
Solution
You want integer values for d and n
60 = (2*a + (n - 1)*d) * n/2 Multiply both sides by 2
120 = (2*3 + (n - 1)*d ) * n
120 = (6 + n*d - d) * n
120 = 6n + n^2*d - d*n
This gives some really wild results. I will list all of them here. and then discuss them.
These are the ones that give results without any question and are correct.
n d tn
2 54 3 57
3 17 3 20 37
4 8 3 11 19 27
Here are some that are the gift of the equation
20 0 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3
Now the equation says the following 3 are correct, but are they? Can you have a negative n? The equation says yes, but I doubt your instructor will.
-5 5
-1 63
-2 22
You can bring these up if you are in a classroom. I wouldn't if you have to submit this to a computer which has absolutely no ability whatever to think about exceptions. Even the 20 0 is one I wouldn't use.

Step-by-step explanation:
its like doing 726 times 106 then just move the decimal. and i looked it up
Based on the ratings system and the summarize() and mean() functions, the code chunk to add is <u>summarize(mean(Rating))</u> and the mean rating is 3.185933.
<h3>How do you find the mean rating?</h3>
To find the mean rating, the complete code should be trimmed_flavors_df %>% summarize(mean(Rating)).
This code would allow you to see the mean rating of your data by combining the summarize() and mean() functions such that you can display summary statistics.
Because of the "mean()" function, the statistic that will be displayed is the mean rating which in this case would be 3.185933.

Answer:
The cow with 4 legs is going 50 miles per hour, while the cow with two legs is going 40 miles per hour.
Step-by-step explanation:
Take the 500 miles apart from your question and divide it by 10 (the hours) after that you get your total: 50 for the 4 legged cow. Minus 10 to get the two legged cow.
