The surface of a river has been marked as (-225) feet and the top of the building at (+18) feet.
If we consider surface sea as a base line to calculate the altitudes of certain place, then altitudes above the the river surface will be positive and the altitudes below the river surface will be negative.
Therefore, (-225) feet of a river means 225 feet below the sea level.
+18 feet of a building means 18 feet above the sea level.
the most common measure of how much sample mean differ from each other is the standard deviation of the sampling distribution of the mean. this standard deviation is called the standard error of the mean
Well 300 and 30 ones would be {330} and 30 hundreds and 30 tens would be 3,300 because 30 times 100 equals 3,000 and 30 times 10 equals 300. Hope this helps :}
Soo first apply the exponent rule (2^5)^1/3*1/4 1/3*1/4= 1/12 so (2^5)^1/12 then you apply the exponent rule again 2^5*1/2 so 5*1/12= 5/12 So the answer would be 2^5/12
