Total 4 sticks
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
Hope this helps you!
Answer:
The demand reduces by $7.12 per month
<em></em>
Step-by-step explanation:
Given




Required
Determine the rate of change of demand
We have:

Differentiate with respect to time

Collect like terms

Factorize

Solve for dx/dt

Given that:
and 
Solve for x


Equate to 0


Using a quadratic calculator, we have:

Demand must be greater than 0;
So: 
So, we have:
; 
The rate of change of demand is:




<em>This implies that the demand reduces by $7.12 per month</em>
Answer:
x=16
Step-by-step explanation:
We can use ratios to solve
8 11
---- = -----------
x 6+x
Using cross products
8(6+x) = 11x
Distribute
48 +8x = 11x
Subtract 8x from each side
48 = 11x-8x
48 = 3x
Divide by 3
48/3 = 3x/3
16=x
Given
