Answer:
(5,7)
Step-by-step explanation:
(1,8)
(9,6)
x+x= 9+1=10
y+y= 8+6=14
ans. divide by 2
(5,7)
Categorical variables can assume values from a range of possible options, whereas quantitative variables can assume possibly infinitely many values from a certain number range.
So, the answer is "the colour of the bookshelf", because there can only be a limited number of possible colours for the bookshelf, whereas its width (no matter the unit measure) and height could be any number.
Answer: slope is 1/3
Step-by-step explanation: make a graph of y=1/3x+9
A transformation is rigid if the original shape remains the same shape and size after the transformation.
Flipping a pancake:
After it is flipped, the pancake should stay the same size and shape, so it is a rigid motion and it is a rotation.
Deflating an air mattress:
Deflating a mattress changes its size, so the transformation is not rigid. This is called a dilation.
Moving a clock's minute hand:
Moving the minute hand does not change the hand's size or shape so the transformation is rigid. This transformation is a combination of a translation and a rotation. The translation is what moves the hand around the center of the clock, and the rotation is what changes the direction of the hand.
Enlarging a photo:
Enlarging a photo changes the photo's size, so this transformation is not rigid. This is called dilation.
Putting a golf ball:
Putting does not change the size or shape of a golf ball, so this transformation is rigid. Putting a golf ball both rotates and moves the ball, so the transformation is rotation and translation.
Looking in a car's rear view mirror:
Assuming the car is moving relative to something behind it(because otherwise there would be no transformation), As things come closer to the back of the car, they would appear larger in the mirror, and as things move away from the back of the car, they would appear smaller in the mirror. Because the size changes when looking at the mirror, this is not a rigid transformation and is called dilation.
I'm not certain how exactly this question is supposed to be answered.
If it wants a ratio, Paul and Jennifer's speeds would be in a ratio of 3:4.
It also could be Paul types 20 words per minute slower than Jennifer.
It could be Paul types 33% slower than Jennifer.
Another answer could be Paul's typing speed is 3/4ths of Jennifer's typing speed.
Feel free to ask any further questions.
