With this problem, you have to do order of operations.
you do the multiplying first (the part in parenthesis)
(5 x 1/3) - (3 x 2/3)
5/3 - 6/3 = -1/3
Ok so there are 7 different options for each of the remaining 7 people to be sat in which means that the answer can be given by 7!=7*6*5*4*3*2*1=5040 different ways
Answer:
Generally an unbiased statistic is preferred over a biased statistic. This is because there is a long run tendency of the biased statistic to under/over estimate the true value of the population parameter. Unbiasedness does not guarantee that an estimator will be close to the population parameter.
Step-by-step explanation:
The answer is 21.
if u look at (7-2) that gives you 5 then 3x5 gives you 15 and then you add 15+6 to get your answer of 21.
