Answer:

cos(x)=0.6

Step-by-step explanation:

cos(x) represents the horizontal distance of the unit vector

sin(x) represents the vertical distance of the unit vector (0.8)

tan(x) represents the distance on the tangent line from the point to the x-axis

cot(x) represents the distance on the tangent line from the point to the y=axis

Answer:

False?

Step-by-step explanation:

I'm pretty sure it's false because wouldn't it simplify to 5y? Sorry if I'm wrong. :)

WITCHER [35]

Answer: 0

Step-by-step explanation:

The line runs through the coordinate (0,0), rather than starting at (0,2), (0,4), or (0,8).

Always remember that you read coordinates as (x,y) which..

X is how many spaces right or left

Y is how many spaces up or down.

The dot plot displays the number of marshmallows added to hot cocoa by several kids. What is the MAD of the data represented in

Pie

Mean absolute deviation (MAD) of the data set indicates the average distance of all elements from mean of the data set.

MAD of the data represented by dot plot in the picture will be Option A.

Elements in the given dot plot are,

3, 4, 5, 5, 5, 5, 5, 5, 6, 7

Steps to be followed for the mean absolute deviation of this data set.

Find the mean of the data set
Find the absolute distance of each element from the mean
Find the average distance of all the elements which will be MAD of the data set.

Step - 1 :

Mean of the data set = $\frac{\text{Total of the data}}{\text{Total number of elements}}$

= $\frac{3+4+5+5+5+5+5+5+6+7}{10}$

= $\frac{50}{10}$

$=5$ (As shown on the dot plot)

Step - 2 :

Absolute distance of each element from the mean of the data set,

3 - 5 = |-2| = 2

4 - 5 = |-1| = 1

5 - 5 = 0

6 - 5 = 1

7 - 5 = 2

Step - 3 :

Average of the absolute distance = $\frac{2+1+0+0+0+0+0+0+1+2}{10}$

= $\frac{6}{10}$

= 0.6

Therefore, Option A will be the correct option.
