umm I think it =(m)(x+−x)
=(m)(x)+(m)(−x)
=mx−mx
=0

Divide the number of bands by the total acts:
3 /16 = 0.1875
Multiply by 100:
0.1875 x 100 = 18.75% were bands. ( Round answer as needed.)
Answer:
C
Step-by-step explanation:
3 - (-12) = 15
6 + (-24) = (-18)
There are 150 confident adults out of 1000.
Selecting four at random withOUT replacement
Probability that all four are confident
=(150/100*149/999*148/997*147/996)
=150!/146! / (1000!/996!)
= 7301/14925090
= 0.00048918
(check: answer < (150/1000)^4=0.00050625, ok)
