Answer:
7a^6b
Step-by-step explanation:
Using the pascal triangle to do this binomial expansion, we find out that the coefficient is 7. The a variables start at the power to which you are expanding and reduce by 1 for every consecutive term. The b variables start at the power of 0 and increase by 1 for every consecutive term. Using this information, we find out that the second term in the binomial expansion (a+b)^7 is 7a^6b
Note that the power of b in the second term is b^1 which is the same as b
Answer:
yes this is the right answer is 4X
Order from least to greatest
-9/2, - 3, 1/2, sqrt(6), 4.2
answer
D.-9/2, - 3, 1/2, sqrt(6), 4.2
----------------------------------
sqrt(10) is irrational number and real numbers
answer is B.irrational number and real numbers
-------------------------
square root (81) = 9
square root (100) = 10
square root (93) is between 9 and 10
so answer
9< sqrt(93) < 10
Answer:
a) It is probability distribution
b) mean = 2.5
c) Standard Deviation = 1.11
Step-by-step explanation:
We are given the following in the question:
x 0 1 2 3 4 5
P(x) 0.033 0.149 0.318 0.318 0.149 0.033
Probability distribution:
Since, the summation of all the probabilities is 1 and each value of probability is between 0 and 1, the given is a probability distribution.
Mean of probability distribution:
Thus, the mean of distribution is 2.5
Standard deviation of probability distribution:
Thus, the standard deviation of the probability distribution is 1.11
