Step-by-step explanation:
2.4x4+9.6
Answer:
60 ft^2
Step-by-step explanation:
a = l x w so,
a = 5 x 12
a = 60
A) 5/10 = (5/10)*(10/10) = 50/100
b) 47/100 +50/100 = (47+50)/100 = 97/100
Answer:
The question is incomplete, but here is the complete part of the question; What is the standard deviation (±0.01) of Juan's mean result? (That is, if Juan kept on making 4 measurements and averaging them, what would be the standard deviation of all his x⎯⎯ 's?) How many times must Juan repeat the measurement so that the standard deviation of x⎯⎯ is 3? (Round your answer to the nearest whole number.)
Standard deviation of his measurement = 5
minimum number of measurement = 12
Step-by-step explanation:
The concept of standard error of mean is applied here which is the approximate standard deviation of a sample distribution or in a normal distribution. Mathematically, Standard error is given as SE = s/√n, where n is the sample size.
The equation implies that the sample error increases as the sample size decreases and vice versa.
The step y step calculation is shown below
