-2, 3 is the correct answer
Answer:
(y, -x -6)
Step-by-step explanation:
<em>The coordinates of PQRS is not given, however we'll assume the coordinates of PQRS to be (x,y)</em>
<em />
The first transformation: 6 units right
Where b = 6
So, the new coordinates will be
The second transformation: 90° clockwise
So, the new coordinates will be
<em>Hence, the new coordinates of PQRS is (y, -x - 6)</em>
Answer:
-12a - 48
Step-by-step explanation:
you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48
since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.
should be 60 cm if not it's 11
Answer:
Step-by-step explanation:
A) From the stem-leaf plot, we see that out of 21 tunas, 5 have dangerous levels of copper since the levels go beyond 5.7 parts per million. The required proportion is 5/21=0.2381
B) Given the sample mean is {x}=4.77, sample standard deviation s=1.16 and the sample size is n=21.
Since the population standard deviation is not known, we use t-distribution.
So the 98% CI for mean is
4.77 ± t{1-0.02 /2,20} x 1.16/sqrt(21) = (4.13, 5.41)}
We are sure with 98% confidence the true copper level (in parts per million) lies in the interval (4.13, 5.41)
