Making a good decision a. requires probabilities for all states of nature. b. requires a clear understanding of decision alternatives, states of nature, and payoffs. c. implies that a desirable outcome will occur. d. all of the alternatives are true. group of answer choices
£11.20 – £33
the minimum value in the table is £11.20. the maximum value in the table is £33. the range of costs is the interval bounded by these values.
the difference between the maximum and minimum is £33 -11.20 = £21.80.
"range" has two possible meanings here. when "range" is applied to function values, it has one meaning. when "range" is applied to statistical data, it can have a different meaning.the extent of function values, from the minimum to the maximum.the difference between the maximum and the minimum.
choose the meaning as defined in your curriculum material.
we are given an equation 5z² + 9z - 2 = 0 and we are to find possible values of z by solving that equation
we will do the task by factorization method:
5z² + 9z - 2 = 0
we can break the midterm (+9z) in two terms such that when they are multiplied the result is -10z² i.e. equal to product of first and third term of the equation above and their sum is equal to 9z
5z² + 10z - z - 2 = 0
5z(z + 2) - 1(z + 2) = 0
taking z+2 common in the above equation
(z+2)(5z-1) = 0
we can write above equation as
(x+2) = 0 (5z-1) = 0
x = -2; 5z = 1
we took $ 24 to the movies.
let total money be
on movies = half of the money =
on popcorn =
on candy = $2
on soda = $3
total money spent = ++ 2+3+1
x = ++ 2+3+1
x- - = 6
- - =6
