QUESTION 6 6.1 The following marks out of 50 were scored by learners in a Mathematics test. 41 33 26 14 45 23 24 27 13 33 12 6.1.1 Write down the range. 6.1.2 What is the modal mark? 6.1.3 Calculate the mean of the marks correct to two decimal places. 6.1.4 Determine the median mark.
Answers
Answer:
The range of a set of numbers is the difference between the highest and lowest values. In this case, the highest mark is 45 and the lowest mark is 6.1.1 Therefore, the range is 45 - 6.1.1 = 38.9.

Side length = L = 29 cm
number of sides = n = 9
Apothen = a = 40 cm
A = nLa / 2 = 9*29cm*40cm / 2 = 5,220 cm^2
Answer: 5,220 cm^2
Answer:
5220 cm
Step-by-step explanation:
A=9/4(a^2)cot(180°/9) is the formula and got 5,220 cm

(x-a)²+(y-b)²=r²
where:
(a,b) is the center
r is the radius
Given that the circle with center (-2,6) and cuts point (-2,10), the equation of the circle will be found as follows:
the radius of the circle will be:
r=√[(x-a)²+(y-b)²]
r=√[(-2-(-2))²+(10-6)²]
r=√[(-2+2)²+4²]
r=√[0+4²]
r=4 units
hence plugging the values to obtain the equation we get:
(x-(-2))²+(y-6)²=4²
simplifying we get:
(x+2)²+(y-6)²=4²

Answer:
Rs 12
Step-by-step explanation:
According to what I have understood;
13/100*4000= Rs Rs 512
So, Rs 4000 plus its VAT is
4000+ 512= Rs 4512
Then we need to find the difference, That is
Rs 4512 - Rs 4000= Rs 12
Answer:13/100x×4000=4500
13x×40=4500
480x=4500
x=4500/480
Answers
To do this we need to work out the major and minor radii and the centre
The centre is at (9, 7)
The major (y) radius is 1 and the minor (x) radius is 5
Therefore the equation is (x-9)/5 + (y-7)/1 = 1
