Answer:
B
Step-by-step explanation:
32x + 24 = 20
24 - 24= 0
20 - 24= -4
32x = -4
32x/32
x
-4/32= -8
X= -1/8
Answer: 0.3023
Step-by-step explanation:
86 band members
26 are senior, 17 plays trumpet. If 4 are seniors and play trumpet, we solve this using the bayes theorem of conditional probability.
Probability of choosing band member that plays trumpet =17/86 = 2/43.
Probability of choosing a senior that plays trumpet = 4/26
Probability that a chosen member is a senior given that he plays trumpet = (2/43)/(4/26)
= 0.3023.
Let Sara weight =x+25
amber wiegh =x
x+25+x=205
x= 90
Sara weight is 90+25= 115
X/3 +4 = 5+x/6
6(x/3 +4 = 5+x/6)
2x+ 24 = 30 +x
x= 6
V=lw*h/3
So since its a square l and w are the same
11*11 = 121
h=20
20/3= 6.6666666
V=121*6.6666666
V= 806.66667
