Answer:
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.
Answer:
1) 34.5°
2) 0.25(180-B)=D
Step-by-step explanation:
180-42=138
1/2x138=69
1/2x69=34.5
0.25(180-B)=D
Answer:
Mean: 45.1
Median: 44
Mode: 41
Step-by-step explanation:
To find the mean, add up all the values, and then divide the sum by the number of values:
46 + 41 + 44 + 39 + 50 + 43 + 41 + 49 + 53 = 406
406 ÷ 9 ≈ 45.1
The mean is 45.1
To find the median, list all the values in numerical order, and find the value in the middle:
39, 41, 41, 43, 44, 46, 59, 50, 53
The median is 44
To find the mode, find the number of time each value appears. The value the appears the most times is the mode:
41 appears twice, and every other number appears once.
The mode is 41
(-2,8) is the image point of A(8,2)
<h3>What is
Rotation ?</h3>
A rotation is a type of transformation which takes each point in a figure and rotates it a certain number of degrees around a given point.
As we know , the rule for rotation of is given by :-
(x,y)⇒(-y,x)
In the above formula (x,y) is the point of pre-image and (-y,x) is a point of image.
Since ,given point of pre-image : A(8,2)
After the rotation of , the image point are :-
(8,2) ⇒ (-2,8)
Therefore,
The image point of A(8,2) is (-2,8) .
