Week 1 2. 3 4 5 6 7 8 Income (thousands of £) 53.5 42.3 39.8 45.1 52.4 19.4 47.9 42.5 The median income for the same eight weeks last year was £49 300 Vera knows that the median income for these eight weeks has decreased this year compared to last year. (a) Work out the percentage decrease of the median income. Give your answer to 2 decimal places.
Using the median concept, it is found that it suffered a 11.16% decrease.
What is the median of a data-set?It is the 50th percentile of the data-set, which is the value that separates the lower 50% from the upper 50%.
In this problem, the ordered data-set, in thousands of £, is given by:
{19.4, 39.8, 42.3, 42.5, 45.1, 47.9, 52.4, 53.5}
It has even cardinality, hence the median is the mean of the 8/2 = 4th and 5th terms, so:
M = (42.5 + 45.1)/2 = £43800.
It decreased from £49300 last year. The percentage decrease is the change divided by initial amount and multiplied by 100%, hence:
P = (49300 - 43800)/49300 x 100% = 11.16%.

The original number is 83.
The original number is 47.
The original number is 74.
The original number is 38.
Answer:
The original number is 47.
Step-by-step explanation:
A and C when reversed make a number less than the original value.
D when reversed makes 83 which is 45 more than 38, the original number.
C, when reversed, gives 74 which is 24 more than 47, the original value.

A triangle has an area of 48 square centimeters. The height of the triangle is 6 centimeters. What is the base of the triangle?
Question :-
A Triangle has an Area of 48 cm² . The Height of the Triangle is 6 cm . What is the Base of the Triangle ?Answer :-
Base of Triangle is 16 cm .Explanation :-
As per the provided information in the given question, we have been given that the Area of Triangle is 48 cm² . It's Height is given as 6 cm . And, we have been asked to calculate the Base of Triangle .
For calculating the Base of Triangle , we will use the Formula :-
[tex] \bigstar \: \: \: \boxed{ \sf{ \: Area \: _{Triangle} \: = \: \frac{1}{2} \: \times \: B \: \times \: H \: }} [/tex]
Where ,
B denotes to the Base .H denotes to the Height .Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf { Area \: _{Triangle} \: = \: \dfrac{1}{2} \: \times \: Base \: \times \: Height } [/tex]
[tex] \longmapsto \: \: \: \sf {48 \: = \: \dfrac {1}{2} \: \times \: Base \: \times \: 6 } [/tex]
[tex] \longmapsto \: \: \: \sf {48 \: \times \: 2 \: = \: 1 \: \times \: Base \: \times \: 6} [/tex]
[tex] \longmapsto \: \: \: \sf {96 \: = \: 1 \: \times \: Base \: \times \: 6} [/tex]
[tex] \longmapsto \: \: \: \sf {96 \: = \: 6 \: \times \: Base } [/tex]
[tex] \longmapsto \: \: \: \sf {Base \: = \: \dfrac {96}{6} } [/tex]
[tex] \longmapsto \: \: \: \textbf {\textsf {Base \: = \: 16 \: cm}} [/tex]
Hence :-
Base of Triangle = 16 cm .[tex] \underline {\rule {180pt} {4pt}} [/tex]
A triangle has an area of 48 square centimetres. The height of the triangle is 6 centimetres. What is the base of the triangle ?
Given : - Area of triangle = 48 cm²Height of triangle = 6 cmTo Find : -Base of triangle Formula Used : -[tex] \blue{\boxed{Area \: of \: triangle = \frac{1}{2} \times b \times h}}[/tex]
Where ,
b = Base of triangleh = Height of triangle Concept : -In this question the concept belongs to the areas of two dimensional shapes i.e. how we can find length , breadth or height with the help of given area .
So let's get started : -[tex] \longmapsto \: 48 = \frac{1}{2} \times b \times 6[/tex]
Now , transposing 2 to left hand side :
[tex] \longmapsto \: 48 \times 2 = 1 \times b \times 6[/tex]
Now , multiplying 48 with 2 and multiplying b with 1 and 6 :
[tex] \longmapsto \: 96 = 6b[/tex]
Now , transposing 6 to left hand side :
[tex] \longmapsto \: \cancel\frac{96}{6} = b[/tex]
Now , by cancelling them we get :
[tex] \longmapsto \: \red{ \boxed{ \sf{b = 16 \: cm}}}[/tex]
Therefore , base of triangle is of 16 cmVerifying : -We know that area of triangle is equal to 48 cm². So :
[tex] \rightarrow \: \frac{1}{ \cancel2} \times \cancel{16} \times 6 = 48[/tex]
Now , by cancelling 16 with 2 we get :
[tex] \rightarrow \: 8 \times 6 = 48[/tex]
So , by multiplying we get :
[tex] \rightarrow \: 48 = 48[/tex]
That means :
[tex] \rightarrow \: L.H.S = R.H.S[/tex]
Hence , Verified .Therefore, our answer is valid .#Keep LearningNeed assistance on this problem

What is the value of x in the equation –2.4x = 8.4?
Answer:
x= 3.5
Step-by-step explanation:
2.4 x= 8.4
x= 8.4 /2.4
x= 3.5
Answer:
X= -3.5
Step-by-step explanation:
You are trying to find what x is, and x is being multiplied with -2.4. The easiest way to find the answer is to divide 8.4 by -2.4. This way, you will get your answer of -3.5. Because two negatives make a positive when you multiply, 8.4 is not negative.
How I solved this.
-2.4x = 8.4
8.4=total
-2.4= Needs to be multiplied with x
x=?
8.4/-2.4=-3.5
Check your work:
-2.4(-3.5)=8.4
Final answer:
x= -3.5
