Answer:
B
Step-by-step explanation:
C = R/1.8 - 273
C + 273 = R/1.8
1.8 * (C + 273) = R
1.8 can also be read as the fraction 9/5.
9/5 * (C + 273) = R
Thus your answer is B. Hope I helped!
If he goes there 4 times a week then $8 plus $2 equals $10 and times $10 by 4 times a week equals $40
So Elijah spends $40 a week at the restaurant

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
