Please name all of the property of multiplication for 4*(-3)*5
PIT_PIT [208]

Answer:

Step-by-step explanation:

You can multiply -3 by 4 and then multiply the result of that by 5, or you could write -3, 4 and 5 in other orders (6 possible orders) and obtain the same result.

I would multiply (-3) by 4, obtaining -12, and then multiply this -12 by 5, obtaining -60.  But I could also multiply 5 by 4, obtaining 20, and then multiply this 20 by -3, obtaining the same -60.

What I have described here are the commutative and associative properties of multiplication.

vodomira [7]

Answer:

5/ 19 ≈ 0.26 = 26%

Step-by-step explanation:

given: student is female. there is a 100% chance that the student is female

probability we want = (favorable outcomes) / (total outcomes)

total outcomes = 19 because there are 19 female students and the student must be female

favorable outcomes = 19 - 14 = 5 females who do not have an A in the class

probability = 5/ 19 ≈ 0.26 = 26%
