1. Is a rotation of 180° the same as a reflection over the y-axis? Please justify your answer in complete sentences.

sp2606 [1]

Answer:

Not the same.

Step-by-step explanation:

Given that there is a rotation of 180 degrees . To check whether this is a reflection over the y axis.

Reflection over the y axis make the coordinates (x,y) as (-x,y)

i.e. this means rotation of 180 degrees about the origin anticlockwise.

Hence just rotation of 180 degrees is not the same as a reflection over y axis.

The conditions are:

i) 180 degree to be rotated anticlockwise

ii) Rotation is about the origin

Hence a rotation of 180 degrees need not always be the same as reflection over y axis.

Answer:

a) $s= 9.74$

D. 9.74

b) $Median= 74$

B. 74

Step-by-step explanation:

Part a

We have the following dataset given:

69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83

We can begin calculating the sample mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X = 75.04$

Now we can calculate the sample deviation with the following formula:

$s =\sqrt{\frac{\sum_{i=1}^n (X_i-\bar X)^2}{n-1}}$

And after replace we got:

$s= 9.74$

Part b

For this case we need to sort the value on increasing way:

[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93

And the median would be the value in the position 13 and we got:

$Median= 74$
