A.
P=2(L+W)
W=29
P is at least (means greater than or equal than ) 134
so
134≤2(L+29) is the inequality
B.
solve
divide both sides by 2
67≤L+29
minus 29 from both sides
38≤L
Length is any value greater than or euqal to 38ft
The answer is 10 if you see my work in the picture
Answer:
30 cm
Step-by-step explanation:
Since the length of tangents drawn from a point are equal, the perimeter is 3+3+9+9+3+3=30
There are three ways to achieve the combination of one male singer, one female singer, and no voice instrumental
Male - Female - No Voice
Male - No Voice - Female
Female - Male - No Voice
Female - No Voice - Male
No Voice - Male - Female
No Voice - Female - Male
For each combination, the probabilities are
MFN = 0.45×0.4×0.15 = 0.027
MNF = 0.45×0.15×0.4 = 0.027
FMN = 0.4×0.45×0.15 = 0.027
FNM = 0.4×0.15×0.45 = 0.027
NFM = 0.15×0.4×0.45 = 0.027
NMF = 0.15×0.45×0.4 = 0.027
Then add all the probabilities we have 0.027×6 = 0.162
