Answer:
A, D
Step-by-step explanation:
The horizontal distance between the points is the difference of their x-coordinates.
A) 5.5 -(-6.5) = 12.0 . . . greater than 11
B) 4.7 -(-3.3) = 8.0
C) 11/3 -(-10/3) = 21/3 = 7
D) 2 -(-12) = 14 . . . greater than 11
10 +38h < =200
subtract 10 from each side
38h < =190
divide by 38
h<=5
Answer: They can rent at most 5 hours
The answer to this problem would be -2.5
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
Answer:
B.11.4
Step-by-step explanation:
The sum the 3 angles of a triangle add to 180 degrees
5x+8x+2x+9 = 180
15x+9 =180
Subtract 9 from each side
15x+9-9 =180-9
15x = 171
Divide by 15
15x/15 =171/15
x =11.4
