k=11 because if you divide 7 on each side to get k alone you 11
Answer:
A. 270.9
Step-by-step explanation:
We know that the rule of significant figures for addition and subtraction states that 'the number of places after the decimal point in the result is equal to the least number of decimal places in each term.'
So, 67.31 - 8.6 + 212.198 = 67.31 + 212.198 - 8.6 = 279.508 - 8.6 = 270.908
Now, the resultant number is 270.908
Using the rule of significant figures, we get that, the number of places after the decimal point in 270.908 will be equal to the least number of decimal places i.e. 1 ( in 8.6 )
Hence, 67.31 - 8.6 + 212.198 = 270.9

Recall that for a random variable
following a Bernoulli distribution
, we have the moment-generating function (MGF)
and also recall that the MGF of a sum of i.i.d. random variables is the product of the MGFs of each distribution:
So for a sum of Bernoulli-distributed i.i.d. random variables
, we have
which is the MGF of the binomial distribution
. (Indeed, the Bernoulli distribution is identical to the binomial distribution when
.)
