Yaa it's true
Step-by-step explanation:
-56=-56
from both side u get the same answer
For 5x-2y=-6 it is 2.5x+3 and for 15x-6y=-6 is 2.5x-1

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)
Answer:
Step-by-step explanation:
Y= 2/1x +7
1(1)= 1(2/1x +7)
1y =2x +7
-2x -2x
-2x + 1y = 7
