Answer:
20% or .2
Step-by-step explanation:
First divide 240 by 300
240/300
this gives you .8, you would then subtract that from 1 to get .2
You can check your answer by multiplying 300 by .2
300*.2
this gives you 60 which is the difference between the 2 numbers
Hope this helps
Answer:
1. Slope = 0.5857
2. Intercept = 31.7
3. Y = 88
4. X = 70
5. 5.4234
Step-by-step explanation:
We have x and y
Mean of x = 91
Mean of y = 85
Sd of x = Sx = 10.5
Sd of y = Sy = 8.2
The registration regression equation
Y - ybar = r(Sy/Sx)(x-xbar)
y - 85 = 0.75(8.2/10.5)(x-91)
Y - 85 = 0.75(0.7809)(x-91)
Y-85 = 0.5857X - 53.3
Y = 0.5857X - 53.3+85
Y = 0.5857X + 31.7
1. Slope = 0.5857
2. Intercept = 31.7
3. If x = 96,
Y = 0.5857(96) + 31.7
Y = 87.927
Y = 88
4. If x = 65,
Y = 0.5857(65)+31.7
Y = 69.77
Y = 70
5. Sy * √(1-r²)
= 8.2 x √(1-0.75²)
= 8.2 x √(1-0.5625
8.2 x √0.4375
= 8.2x 0.6614
= 5.4234

Answer:
its an rhombus
Step-by-step explanation:
Well, you didn't bother to list the answer choices, so there's no way
I can help you pick the correct choice.
But I can tell you this: Any time a figure is dilated by a scale factor of 1,
the image is congruent to the original figure.
