Answer:
The probability that at least one of the three smoke detectors functions properly = 0.996625
Step-by-step explanation:
Given that:
a certain brand of smoke detector functions properly 85 percent of the time
Let X represent the certain brand of smoke detector
X = 85%
X = 0.85
Let the probability that at least one of the three smoke detectors functions properly be P(Y)
P(Y) = 1- (1 - X)³
P(Y) =1 - (1 - 0.85)³
P(Y) = 1 - 0.003375
P(Y) = 0.996625
∴
The probability that at least one of the three smoke detectors functions properly = 0.996625

Answer:
Option (2) CPCTC
Step-by-step explanation:
In the given regular triangle ADF, all sides and angles of the triangle will be equal
∠A = ∠D = ∠F = 60°
And DE = EF [Since E is the midpoint of side DF]
Statements Reasons
1). ∠D ≅ ∠F Given
2). ∠DBE ≅ ∠ECF Given
3). DE ≅ EF Given
4). ΔDBE ≅ ΔECF By AAS property
Therefore, DB ≅ FC
Option (2) Corresponding parts of the congruent triangles are congruent (CPCTC)
Answer:
15) x = 42
Remember: They are supplementary, add the two values and set it equal to 180.
16) The graph is not labeled so I’m not sure where ABC is.
