l壱INTRODUCTION
Numeracy segment provide various understanding of technicals and analytical aspects
that will be helpful to determine various positive outcomes. The project report provide various
information about various financial techniques such as investment appraisal tools and other
crucial financial systems. This consists of two sections of their respective data evaluation.
l壱SECTION 1
l弐QUESTION 1
Powers and Roots:
a) Simplify (2 marks)
b) Simplify (2 marks)
c) Evaluate (2marks)
[a]Power: It is a number which indicate about total times which uses the number in a
multiplication. This is shown as a small number to the right and above base number. The another
name of power is index or exponent. A number which is other than 0 is taken to the power 0
which is define to be 1. In order to simply power of a power , exponent has to be multiples by
keep the base same. Like for example: (xa)b= xa·b, in case of any positive number X and
integers a and b the above equation would be taken into account.
Problem 1:
Simplify (6.0*105) / (25*10-4)
=(60*104) / (25*10-4)
Cancellation of 60 with 4 times 15 and applying the formula of am/an=a m-n
= 4*104-(-4)
= 4*108
4

[b] Root: It is known as root of a number X is said to be another number which is being
multiplied by itself in so many time. A basic word to which affixes are taken into consideration
as root. Like for example, second root of 4 is 2, because 2*2=4. From this, it has been clear that
second roots are always count as square root.
[c] Evaluating square roots: It is simply means that to calculate value of the given problems.
Such as ?3+1
c) =1.73+1=2.73
l弐QUESTION 2
a) Express the power 100
1/2
using the root notation and evaluate. (2
marks)
b) Evaluate (2 marks)
c) Simplify 7 (2 marks)
d) Scientific notation allows one to express large or small numbers in a simpler form.
Express the UK population of 65,648,000 in a scientific notation (2
marks)
[A]: It has been seen that every non-negative real number has unique square root which
determine as square root. It has bee denoted by ?a, where ? is said to be radical sign.
=1001/2
=?100
= 10.
[b]: A square root is known as effective number which is a number that can multiply by itself to
a proper value. It is simply determine as written symbols which is used to indicate amounts and
any other value.
[c] In order to simplify 7 there are various ways which is being present underneath:
Round it off:
Create zeros: In this case, 7 becomes 10.
[d]: Calculation of scientific notation
= 6.5648 × 107
= 6.5648e7
= 65.648 × 106

= 65648000
(real number)
l弐QUESTION 3
Ann Miller invests £150,000 at an interest rate of 6% p.a. Calculate the final balance
after 5 years.
a) Using simple interest? (1 mark)
b) Using interest compounded annually? (3 marks)
c) Using interest compounded semi-annually? (3 marks)
d) Using interest compounded quarterly? (3 marks)
[a]: Simple interest: It is known as one of the simple and quick method to computer the interest
charges on the principles amount. It is determine by multiplying the everyday interest rate
through the principles with total number of days available among payments.
Formula: SI: P*R*T/ 100
SI: 150000*0.06*5
: $45000
Usually, the interest is included onto the initial amount of figures which is calculated
with 6% rate. The new amount of 5 year they will get is:
=150000+45000= 195000.
[b]: Interest compound annually: It is know as total addition of interest which is added to the
principles total of investments. This happens to be outcome of reinvesting interest, rather than
gainful it out. Formula: A= P(1+r/n)nt

annually, how long will it take her to receive the balance of £33,000?
(4 marks)
b) Using Rule 72, calculate how long will it take Eliza to double her investments?
(2 marks)
c) Mr Ramsbottom invests £32,000 in a bank savings account and after 10 years his
balance is £45,200.20. Calculate the compound interest rate he received and
round your answer to the second decimal place. (4 marks)
[a]: FV= PV(1+r)n
33000=22000(1+0.02)n
= 20.5
It will be take approximately 20 years 5 month and 22 days for the account to go from
22000 to 33000.
[b]: Rule 72 provide simple concept about total amount which is going to double investments.
Y = 72 / r
y= 72/2 =36
[c]:
In case total savings account which is being invested in the bank compounded yearly
with principles amount of $32000. After 10 years, the total amount increase to $45200.2. they
would get 3.5% of interest per annum.

B): Preparation of Histograms
It is known as effective charts which is used for regulating various data, where the bins
indicate various range information. The major difference of using histograms is only to make use
for the purpose of plotting overall frequency of score those are available in regular data series.

c): Interpretation:
From the above information collected from the data provide vital outcomes after preparing
histograms charts. The results are more clear that there is huge fluctuation in the total marks
collected by various student from that particular test. The histograms graphs provide vital
outcomes that maths, science and social science is provide more effective percentage in total

l弐Question 8
Probability is a measure of the likelihood and can be stated as a ratio, percentage or generally as
a number between zero and one.
a) What is the probability when the likelihood is impossible? (1 mark)
b) What is the probability when the likelihood is certain? (1 mark)
c) Express the probability of 0.06 as a % (2 marks)
d) Josiah tossed a coin and thrown a die at the same time (simultaneously). Work out the
probability of getting a head on the coin and a 5 on the die.
(4 marks)
[a]: Probabilities by their own explanation is level to which an activities is likely to be happen. It
use to measure overall ratio of favourable cases to the entire number of cases in best possible
manner. Henceforth, number of components is the overall set of favourable situations which is
10

less than or equal to the number of elements in a given data series. The ratios would in that
condition ends with 1 and less than 1.
The major point is that, probabilities equals only when favourable number in a given case
are similar as that of the whole number of situations. Definitely, it is not possible that it become
zero. It is defined as likelihood or any modification of arises in an given activities. Few events
are unlikely to be arises through not impossible during other conditions which is more likely to
be occurs.
B]:
It has been seen that a likelihood operate often simply the likelihood which is based on
the parameters of a statistical model in a particular data. The scale values in a specific data
range such as the actual probabilities of a data would provide parameters value. The LR are used
to assess various crucial things such as potential utility of a specific diagnostic test. Likelihood is
generally, a ratio of probably that test outcomes is correct to the best probability that test results
is incorrect.
c):
The probability of 0.06 is represent 0.94%
d]: Probabilities:
For a coin, there are 2 possible outcomes is possible such as= [Head, Tail]
In case of die which is having ( 6 sided) so a maximum of 6 possible results =[1,2,3,4,5,6]
Now, when coin is tossed and die is rolled at the same time, 2*6=12 possible outcomes can be
attain. Such as,
(Head, 1), (H, 2), (H, 3), (H,4), (H,5), (H, 6), (T,1), (T, 2), (T, 3), (T, 4), (T,5), (T,6)
So after analysing, all these results it has been seen that the chances of getting head is 2.
Probabilities= 2/12=1/6.

l弐Task 1 - Two Real life examples

Give two real-life situations or problems in businesses that involve the topics studied in
this module (e.g. powers and roots, simple and compound interests, linear relationships, graphs,
probabilities and Net Present values (NPV)).
(1) Let's assume Company XYZ wants to acquire another company ABC. For this purpose they
have taken estimation of their last 10 year performance. As NPV is said to be an effective
investment appraisal techniques which can be helpful for the company's in order to make
analysis of their actual return they are getting in present time. The below mentioned is the case
situation which would provide well effective information about their financial position by seeing
those XYZ company will decide whether to make accept this proposal.

In case of car loan:
It has been seen that car loan are amortised on monthly basis, which means that a certain
portion of the loan will go on to pay outstanding loan balance every month. Like for example: It
assume that a car loan of $ 20000 on which a simple interest is going to be payable at 2 %. The
loan would repaid after 5years in equal instalments.
I= P*R*T
= 20000*0.02*5
=2000
Total amount after completion of 5 years = 20000+2000
= 22000.
This much amount they are going to be gain over there total principles amount of 20000.
Usually in recent time, the interest is included onto the amount to determine exact figure after 5
years.
