Answer:
L' = (-1,1)
N' = (-1,4)
M' = (-4,2)
Step-by-step explanation:
Reflecting across y = x basically means switching the positions of x and y. In this case switching the coordinates.
L = (1,-1) and L' = (-1,1)
N = (4,-1) and N' = (-1,4)
M= (2,-4) and M' = (-4,2)
Ans:- 4:12:24
first add the ratios,that is =10
Then find the amount the 1st person payed= 1/10 *40
=4
2nd person payed= 3/10*40=12
3rd person payed= 6/10*40=24
therefore your answer is 4:12:24
can you also answer my question
Answer:
z = 10
Step-by-step explanation:
The value of the z-statistic is given by:
In which:
X is the measured value.
is the expected value.
is the standard deviation of the sample. 
is the standard deviation of the population.
In this question:
The mean length was 2.9 inches, and the population standard deviation is 0.1 inch.
This means that 
Random sample of 100 screws.
This means that n = 100.
To see if the batch of screws has a significantly different mean length from 3 inches, what would the value of the z-test statistic be?
3 inches, so
