<h2>
Step-by-step explanation:</h2>
We will use the Gaussian elimination method to solve this problem. To do so, let's follow the following steps:
Step 1: Let's multiply first equation by −2. Next, add the result to the second equation. So:
Step 2: Let's multiply first equation by −1. Next, add the result to the third equation. Thus:
Step 3: Let's multiply second equation by −35, Next, add the result to the third equation. Therefore:
Step 4: solve for z, then for y, then for x:
By substituting 
into the first equation, we get the 
. So:
The function will exist on all real numbers. Hence the domain of the exponential function given is all real numbers
<h3>Domain of a function</h3>
The domain are independent values of an expression for which it exist. The standard exponential equation is expressed as y = ab^x
Given the exponential function as shown:
y = 5(3)^x
The function will exist on all real numbers. Hence the domain of the exponential function given is all real numbers

Answer:
I have given it step by step below.
Step-by-step explanation:
(i) Mean = sum of observations/total no. of observation
= 23 + 20 + 4 + 19 + 28 + 35 + 25 + 0 +1 + 30/ 10
= 185/10
= 18.5
(ii) additional 35 runs
New Mean
=previous total + 35/10 + 1 (the 1 gets added in denominator because of the additional observation)
= 185 + 35/11
= 220/11
= 20
