The 8 is in the ten thousands place, so it equals 80,000.
7,328,562
The 7 is in the millions place, to it equals 7,000,000.
The sum is the value of two numbers added together (the answer to an addition problem).
80,000 + 7,000,000 = 7,080,000
Answer:
17.8
Step-by-step explanation:
First, round the two. umbers to the nearest the th, or the first number past the decimal. 19.28 rounds to 19.3 (round up because 8 is bigger than 5) and 1.546 rounds to 1.5 (round down because 4 is smaller than 5). Then subtract. 19.3 - 1.5 = 17.8
Answer:
1.691
Step-by-step explanation:
Standard error of the mean is expressed as SEM = S/√n
S is the population standard deviation
n is the sample size (number of observation)
Given S = 27 and n = 255
SEM = 27/√255
SEM = 27/15.97
SEM = 1.691
Hence the standard error of the mean is 1.691
The answer to the question is 15x+30-64
