I got 23, 18, and 25 for the first one idk it's not on there though. Did you get an answer at all? I could try to get it again maybe I did something wrong
900 centimeters is the answer to this question
Step-by-step explanation:
B. Yes, we are 99% confident that the population mean is within the interval.
C. Yes, 225 is below the interval minimum, so it is reasonable to conclude the average cholesterol level is greater than 225 mg/dl.
D. No. Increasing the sample size would decrease the margin of error, so the ends of the interval would move closer to the sample mean of 251.9. So the interval minimum would still be higher than 225.
The 3 inside angles of a triangle need to equal 180 degrees.
Since you are given 2 angles, subtract both of those from 180 to find X.
X = 180 - 70 - 30 = 80 degrees.
X = 80
Answer: (-2, 5/3)
explanation: since you are given x = -2, just plug that into the equation and solve.
