Any value that satisfies the equality.
E.g. 2x + 4x = 10 the value that makes this true is 2
or
x^2 = 2 The values that would make it true are 4 and -4, since the squared of any number is always a positive.
It's not prime and it can be timed by 2
Answer:
The standard error of the mean = 5.14 mins
Step-by-step explanation:
Number of random sample (n) = 20
Mean(X) = 31.25 mins
Standard deviation (α) = 23.7 mins
Standard error of mean =
standard deviation / √sample size
= 23.7/√20
= 23.7/4.4721
= 5.14 mins
