Answer:
(x,y) maps to (-y,x).
Step-by-step explanation:
Use vertex I as an example.
Pre-image I is graphed at point (-3,2), while image I' is graphed at point (-2,-3) .
In order to change between these points, the x and y coordinates must be swapped, as well as multiplying the y coordinate by -1.
Answer:
The answer is 4
Step-by-step explanation:
For a poisson distribution, the variance is equal to the mean. Since the average number of defects per product is 2, it means that the mean per product is 2. Hence for 32 units it is 16 divided by 2 which is 16.
Also, since the square root of variance is equal standard deviation, the square root of 16 is 4.
It would be 7 beacause the # after the decimal is the tenths pleace
