Cost of a television Ms. Singh wants to buy = £840
Ms. Singh's weekly wage = £300
Money she saves each week :
= 40% of her weekly wage
![=\tt 40\% \: of \: 300](https://tex.z-dn.net/?f=%20%3D%5Ctt%2040%5C%25%20%5C%3A%20of%20%5C%3A%20300)

![\color{plum} = \tt£120](https://tex.z-dn.net/?f=%5Ccolor%7Bplum%7D%20%3D%20%5Ctt%C2%A3120)
Thus, Ms. Singh's weekly savings = £120
Number of weeks in which she will be able to buy a TV :
![= \tt \frac{840}{120}](https://tex.z-dn.net/?f=%20%3D%20%5Ctt%20%5Cfrac%7B840%7D%7B120%7D%20)
![\color{plum} =\tt 7 \: weeks](https://tex.z-dn.net/?f=%5Ccolor%7Bplum%7D%20%3D%5Ctt%207%20%5C%3A%20weeks)
Therefore, Ms. Singh will be able to buy a TV from her savings in <u>7 weeks</u>.
Answer:
A = P * a / 2
A = 81.25
Step-by-step explanation:
We have that there is a corresponding formula for a regular decagon, which depends on the apothem and the perimeter, it is the following:
A = P * a / 2
In this case, the perimeter is the sum of all the sides, that is, 10 sides, therefore:
P = 10 * 3.25
P = 32.5 meters
We replace:
A = 32.5 * 5/2
A = 81.25
Which means that for that regular decagon, the area is 81.25 square meters.
The problem ask to explain the use if the normal curve to compare that
score to the population and the best explanation is that the normal
curve depends on a lot of assumptions. If the population score are
normally distributed, we will know its mean and standard deviation, so
can tell that our particular individual's row score falls on that
distributions.
