Answer:
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).
Step-by-step explanation:
To find the interval, we can just make the conversion of the values from pounds to kilograms.
Each kilogram has 2.2 pounds. So, to realize the conversion from pounds to kilograms, we divide by 2.2.
Confidence interval: (102.3 pounds, 106.5 pounds).
102.3 pounds = 102.3/2.2 = 46.5 kilograms
106.5 pounds = 106.5/2.2 = 48.41 kilograms
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).
Answer:
All real numbers
Step-by-step explanation:
-3(10x - 4) = 5(-6x + 1) + 7
-30x + 12 = -30x + 5 + 7
-30x + 12 = -30x + 12
-30x = -30x
0 = 0
Best of Luck!
Answer:
The larger number = 116
Step-by-step explanation:
Let the smaller number = x
Given that one number is 78 more than another, so
The larger number = x+78
Given that if we add 12 to the smaller number, the result is 50, so
subtract 12 from both sides
Simplify
Therefore,
- The larger number = x+78 = 38+78 = 116
Thus, the larger number = 116
