Answer:

Step-by-step explanation:
We do FOIL to solve this
Answer:
Average of the draws equals 420
Standard Error = 11.88
Step-by-step explanation:
Given



Solving (a): The average of the draws
This implies that we calculate the sample mean
This is calculated as:
--- Sample Mean = Population Mean
So, we have:

Solving (b): The standard error
This is calculated as:

So, we have:

Using the calculator, we have:

answer = 7&3
step by step solution
let's take X and Y two intigers
X+Y=10
X-Y=4
adding both equation
X=7
Y=3
