Answer:
(-9, -5)
Step-by-step explanation:
Ok, so when you move an image to the right, you are moving along the x-axis, and when you move up, you are moving up the y-axis. So if the altered image is (x,y) and the values are (-5, -1), you reverse what has been done to the image. In this case, since we moved to the right 4 units, we know that means we added 4 to x, so we subtract 4 to get -9. And then, for the y-value, because we added 4, we do the opposite, and subtract 4 to get -5. So the pre-image should be (-9, -5)
Answer:
14 students
Step-by-step explanation:
We can set up a percentage proportion to find 2% of 700.
, and we can use the cross products property to find the value of x.
Hope this helped!
All you need to do is add them together. 14+(-7)+9=16
Answer: 0.9660
Step-by-step explanation:
Given: Mean : 
Variance : 
⇒ Standard deviation : 
The formula to calculate z is given by :-
For x= -3
The P Value =
For x= 3
The P Value =
Hence, the probability that a given error will be between -3 and 3=0.9660
