Answer:

Step-by-step explanation:

Mode: Mode is the value that appears most often in the data set

115 , 32, 48 , 11 , 112 , 67 , 91 , 11 ,160 , 11 , 91 , 128 , 147

Here 11 comes 3 times

So, mode = 11

$\sf \boxed{\text{Mean =$\dfrac{sum \ of \ all \ the \ data}{number \ of \ data \ sets}$}}$

$\sf = \dfrac{245 + 65 + 123 + 100 + 22 +43 + 36+ 177 + 21 }{9}\\\\ =\dfrac{832}{9}\\\\= 92.4$

Mean = 92.4

Range :

3) Range = maximum value - minimum value

= 297 - 19

= 278

4) Range = 129 - 6

= 123

Median: Arrange the data set in ascending order and find the middle term

5) 3 , 3 ,3 , 21 , 87 , 100 , 124, 174 , 191

n = 9

As the number of terms is odd number,

$Median = (\dfrac{n+1}{2})^{th} \ term\\$

$\sf = (\dfrac{9+1}{2})^{th} \ term\\\\= (\dfrac{10}{2})^{th} \ term\\= 5^{th} \ term$

= 87

5 tins of soup have a total weight of 1750 grams.

WITCHER [35]

Answer:

30 grams

Step-by-step explanation:

So, first I had to figure out what 1 tin weight. Which was 350 grams because I divide 5 into 1750. Then I did 350+4 which gave me 1,400. I knew that there was three packets so 30 grams per packet should be the answer because 30×3 is 90 grams.

Answer:

Step-by-step explanation:

<h3>Given Question:</h3>

$r + {s}^{2}$

Given values -

r = 4 , s = 1

Therefore putting their values in the question,

Answer:

The answer is below

Step-by-step explanation:

Select the two answers

a.A would be at (-3,5)

b. B would be at (-1,5)

c.C would be at (-5,8)

d. It would end at the same spot if the original design was reflected across the x-axis,followed by a 180 degree rotation about the origin,followed by translation 1 unit to the left.

E.It would end at the same spot if the original design was reflected 180 degrees rotation about the origin,followed by a translation 3 unit up and translated 1 unit to the left

E.It would end at the same spot if the original design was reflected 180 degrees rotation about the origin,followed by a translation 3 unit up and translated 1 unit to the left

Solution:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

If a point X(x, y) is translated b units up and a units right, the new point is X'(x + a, y + b). If a point X(x, y) is translated b units down and a units left, the new point is X'(x - a, y - b)

If X(x, y) is reflected across the y axis, the new point is X'(-x, y)

If X(x, y) is reflected across the x axis, the new point is X'(x, -y)

If X(x, y) is rotated 180 degrees, the new point is X'(-x, -y)

If A(2, 0), B(4,-2), C(2,-5) and D(0,-2). If he translates it 5 units to the left and 3 units down the new point is A'(-3, -3), B'(-1, -5), C'(-3, -8), D'(-5, -5). If it is then reflected across the y axis, the new point is A"(3, -3), B"(1, -5), C"(3, -8), D"(5, -5).

If A(2, 0), B(4,-2), C(2,-5) and D(0,-2). If he reflected across the x-axis the new point is A'(2,0), B'(4, 2), C'(2, 5), D'(0, 2). If it is then rotated 180 degrees, the new point is A"(-2, 0), B"(-4, -2), C"(-2, -5), D"(0, -2). If it is translated 1 unit left the point would be A"'(-3, 0), B"'(-5, -2), C"'(-3, -5), D"'(-1, -2)

If A(2, 0), B(4,-2), C(2,-5) and D(0,-2). If he rotated 180 degrees the new point is A'(-2, 0), B'(-4, 2), C'(-2, 5), D'(0, 2). If it is then translated it 3 units up and 1 units left, the new point is A"(-3, 3), B"(-5, 5), C"(-3, 8), D"(-1, 5).
