D. 40
follow the pattern
1 band director calls 3 members. = 4
Each member calls 3 more members 3(3) = 9
Then each of those 9 call 3 more members 9(3) = 27
Add them up
4+9+27 = 40

2. 3x+2y=6
Step-by-step explanation:
$560* (30/100)
= $168
Reniel saved $168 last week~
This is not a difficult question and I will help you solve it :)
When calculating 1/10 from 40, what we have to do is this:
(1/10) * 40 = 4
This means that we have to multiply 40 by 1 and divide by 10 :)
So the answer in this case is 4.
Answer:
0.19
Step-by-step explanation:
Given that :
Total possible outcomes = 10
If the same name can be chosen twice, then probability is with replacement ;
Probability = required outcome / Total possible outcomes
Required outcome = number of Collins in name = 1
Probability of choosing Collins atleast once ;
2[P(Collins) * P(not Collins)] + P(Collins) * P(Collins)
P(colins) = 1/10
P(not Collins) = 9/10
2(1/10 * 9/10) + (1/10 * 1/10)
2(9/100) + (1/100)
18/100 + 1/100
19/100
= 0.19
