Answer:
28 ft
Step-by-step explanation:
mark me brainliest!
The table is missing, so i have attached it.
Also, the correct question is;
The surface area of the East China Sea is k times the surface area of the Baltic Sea.
Work out the value of k.
Give your answer to the nearest whole number
k = 3
From the attached table,
Surface area of east china = 1.25 × 10^(6) km²
Surface area of Baltic sea = 4.22 × 10^(5) km² = 0.422 × 10^(6) km²
We are told that the surface area of East China Sea is k times that of the surface area of the Baltic Sea.
Thus;
1.25 × 10^(6) = k × 0.422 × 10^(6)
k = 1.25/0.422
k = 2.96
Approximating to whole number gives;
well the shape is same but the measurements are different

Answer: (1583.63, 1672.37)
Given : Sample size : n= 83
Sample mean :
Sample standard deviation :
The population standard deviation is unknown .
The confidence interval for population mean :
For 90% confidence , significance level =
Using t-distribution table , Critical t-value =
, where n-1 is the degree of freedom.
Now , 90% confidence interval for the mean square footage of all the homes in that city will be :-
Hence, the 90% confidence interval for the mean square footage of all the homes in that city = (1583.63, 1672.37)
