We can find the common multiples of two or more numbers by listing the multiples of each number and then finding their common multiples. For example, to find the common multiples of 3 and 4, we list their multiples and then find their common multiples. Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36,
Step-by-step explanation:
this is the rai d right?
Just 9
I'm not sure for the second one but I think 1 ft
<ABC + <ABC = 180
3x- 9 + 7x - 1 = 180
10x - 10 = 180
10x = 190
x = 19
<ABC = 3x- 9 = 3(19) - 9 = 48
Answer:
Expected number of books = 1.0
Step-by-step explanation:
Expected number of books, E(x) = ∑xp(x)
∑ = Summation
x = books
p(x) = probability of purchasing a book
E(x) = (0*0.4) + (1*0.2) + (2*0.4)
E(x) = 0 + 0.2 + 0.8 = 1.0
