Answer:
Kindly check explanation
Step-by-step explanation:
If the null is rejected, then we conclude that the average Consumption of beer and cider by customers who are 21 years and above is greater than 26.1
A type 1 error is committed if the null hypothesis is incorrectly rejected ; this means we will be concluding that customers who are 21 years and older have higher average Consumption when they actually do not. This may lead to a restriction on beer consumption in the city when there actually isn't a need for it.
For type 2 error, a false null is incorrectly accepted, in this scenario, we are saying that the consumption of beer and cider is not beyond the mean value when in actual sense it is.
We were told that the distance 
is directly proportional to the time 
.
We write this mathematically as,
We can now introduce our constant of variation and write the equation for the direct equation as;
where 
is the constant of variation or constant of proportionality.
We substitute 
and 
, in to the equation of variation to obtain the constant of proportionality.
That is;
This implies that,
This simplifies to give us,
Now our equation of proportion becomes,
When T=20
Writing this as a mixed number we obtain,
This can also be rewritten as
correct to one decimal places.

Answer:
a) The cash price of the gas stove was 1300 ringgit
b) The original unpaid balance = 1200 ringgit
The original unpaid balance including interest = 1320 ringgit
Step-by-step explanation:
Given:
Cash price of the gas stove = X ringgit
Down payment = RM100
Total monthly payments = 24
Each payment = RM55
Interest rate charged = 10%
now,
After down payment,
Remaining balance = RM(X - 100)
Balance after interest = RM(X - 100) × ( 1 + r)
= RM(X - 100) × ( 1 + 0.1)
= RM(1.1X - 110)
also,
amount paid in total installments
= 24 × RM55
= RM1,320
and,
RM1,320 = RM(1.1X - 110)
or
1.1X = 1,430
or
X = 1300
Hence,
a) The cash price of the gas stove was 1300 ringgit
b) The original unpaid balance = X - 100
= 1300 - 100
= 1200 ringgit
and,
after including interest
The original unpaid balance = 1.1(X - 100)
= 1.1 × (1300 - 100)
= 1320 ringgit
