Answer: 3m
Step-by-step explanation:
You're multiply 3 by m. Since this isn't possible unless you have m's value, you must write the expression as 3m.
Answer:
PR = 5 because LP + PR = LR according to the Segment Addition Postulate, and 7 + 5 = 12 using substitution
Step-by-step explanation:
The naming of the segments suggests that point P is between L and R, so that ...
LP + PR = LR
This corresponds to the last choice.
_____
<em>Comments on the alternate interpretation</em>
On the other hand, if point L is between P and R, then the segments are PL and LR. The Segment Addition Postulate would tell you that ...
PL + LR = PR
The Reflexive Property of Congruence would tell you that PL = LP. The Substitution Property would tell you LP can be substituted into this equation, making it ...
LP + LR = PR
and by the commutative property, ...
LR + LP = PR.
Multiple properties of addition and congruence are involved with this interpretation, which more or less matches the third choice. That is, the simple explanation of answer choice 3, by itself, is insufficient to explain why the length of PR should be considered to be 19, not 5.
Answer:
D
Step-by-step explanation:
the n th term ( explicit formula ) of a geometric sequence is
•
= 

where r is the common ratio and
the first term
here r =
=
=
and
= 64, hence
= 64
→ D
Answer:
1/10
Step-by-step explanation:
P(a successful member
had Bertha as her trainer) = P(Bertha being you trainer) x P(being successful if
trained by Bertha)
= 1/3 x 30/100
= 30/300
= 1/10
