Answer:
0.68
Step-by-step explanation:
Given that :
P(trombone | snow) = 0.8 ;
P(trombone | no snow) = 0.5
P(snow) = 0.6
P(trombone) = P(trombone | snow) * p(snow) + P(trombone | no snow) * p(no snow)
P(no snow) = 1 - 0.6 = 0.4
Hence,
P(trombone) = P(trombone | snow) * p(snow) + P(trombone | no snow) * p(no snow)
P(trombone) = (0.8 * 0.6) + (0.5 * 0.4)
P(trombone) = 0.48 + 0.20
P(trombone) = 0.68
Answer:
The triangles SYX and SYZ are congrient so by CPCTC
,
and
.
Step-by-step explanation:
Given information: YS is the perpendicular bisector of XYZ.
In triangle YXS and triangle YSZ,
(YS is the perpendicular bisector of XYZ)
(Common side, Reflexive property)
(YS is the perpendicular bisector of XYZ)
By ASA postulate,

The corresponding parts of congruent triangles are congruent. so,



Point slope form
y-y1=m(x-x1)
m=slope
(x1,y1) is a point
(-5,-1)
x1=-5
y1=-1
m=-5/4
y+1=-5/4(x+5)
y=-5/4x-29/4
Answer:
the first one bc look at the m's and the d's the others look the same
Step-by-step explanation:
First make improper fractions: —> 13/3 divided by 7/3
Then multiply by the reciprocal: —> 13/3 times 3/7
The threes will cancel making the answer 13/7 or 1 6/7
