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

Yes, the blank numbers that can be written as a product of blank factors are called the prime factorization of a number. It can also be composite numbers where it can be written also as the product of prime factors.
Answer:
The answer would be 26
Step-by-step explanation: (Broken down into 2 parts)
-PART ONE- solving (12-7) x (8-5) -7
(12-7) x (8-5) -7 (do whats in parentheses first)
(5)x (3) -7 (multiply 5x3)
15-7 (subtract)
ANSWER- 8
-PART TWO- solving (16-4) + (10 - 12 divided by 3)
(16-4) + (10 - 12 divided by 3) (do what is in parentheses)
12 + 10-4 (add)
22-4 (subtract)
ANSWER- 18
Now combine the two answers 18+8 and you get 26
Therefore, 26 is the final answer.
Hope this helps!!
