Coordinate of real point = J(0, 4)
Then, Coordinate of Image = J'(-3, 8)
So, Factor: x = -3-0 = -3
y = 8-4 = 4
So, Your Final Answer would be: Option C) (x-3, y+4)
Hope this helps!

Step-by-step explanation:
Max-Min
249.99-201.49= 48.50
Answer:
The correct answer is A
Step-by-step explanation:
Answer:
90% confidence interval for the mean is between a lower limit of 3.08 days and an upper limit of 3.18 days.
Step-by-step explanation:
Confidence interval is given as mean +/- margin of error (E)
mean = 3.13 days
sd = 0.48 day
n = 250
degree of freedom = n-1 = 250-1 = 249
confidence level (C) = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 249 degrees of freedom and 10% significance level is 1.65153
E = t×sd/√n = 1.65153×0.48/√250 = 0.05 day
Lower limit of mean = mean - E = 3.13 - 0.05 = 3.08 days
Upper limit of mean = mean + E = 3.13 + 0.05 = 3.18 days
90% confidence interval is (3.08, 3.18)
