Looking at the angles of the triangles
N=S
M=R
O=T
so MON would be RTS
Answer:
10*4-6*2=28
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
This is a division problem.
We want to find how many 1/3 liters are in 4⅔ liters.
We divide to obtain:

Or

Convert to improper fraction.


This simplifies to

Therefore there are fourteen ⅓ liters in 4⅔ liters
Answer:

Then we can find the mean and the standard deviation with the following formulas:
> mean(a)
[1] 50.72451
> sqrt(var(a))
[1] 7.470221
Step-by-step explanation:
For this case first we need to create the sample of size 20 for the following distribution:

And we can use the following code: rnorm(20,50,6) and we got this output:
> a<-rnorm(20,50,6)
> a
