4 - 2(x + 3) = 5
4 - 2x - 6 = 5
-2x - 2 = 5
-2x = 5 + 2
-2x = 7
x = -7/2 or = -3 1/2
Answer:
The standard deviation for the number of bags that are underfilled is 2.236.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval. The variance is the same as the mean, which mean that the standard deviation is the square root of the mean.
In this question:
Expected number of underfilled bags in a sample of n bags is:

1000 bags, so

Standard deviation 
The standard deviation for the number of bags that are underfilled is 2.236.
The value of f(1) = 81
Step-by-step explanation:
For the recursive function, f(n+1) = one-half(n)
Thus, when n = 2,
f(3) = 9
If n = 1,
f(2) = 9×3
f(2) = 27
If n = 0,
f(1) = 27 ×3
f(1) = 81

Answer:
it is b
Step-by-step explanation:
I did it on ed 2020
Answer:
see below
Step-by-step explanation:
a) 1/7 is the smallest, so a is in the correct t location.
b) is 1/3, which is larger than 1/4
c) is 2/10 or 1/5, which is smaller than 1/4
so on the graph, b and c are backwards. c should be to the right of 1/4, and b should be to the left.
