If you’re good with permutations in math 30 please help answer the question below A license plate consists of 3 letters, followed by 3 numbers. Repetitions are not allowed. If any letter may be used except for U and I, and the allowed digits are 3, 4, 5, 6, 7, 8, and 9, how many different license plates can be produced?

a) 500 405

b) 900 800

c) 1 059 776

d) 2 550 240

b

i think its b because i always GUESS b and get it wron- correct

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
