If it snows tomorrow the probability is 0.8 that John will practice his trombone if it does not snow tomorrow there is only a 0.
Bas_tet [7]

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

YS is the perpendicular bisector of XYZ and YS is a shared side of XYS and ZYS. which of the following must be congrent in order
german

Answer:

The triangles SYX and SYZ are congrient so by CPCTC XY\cong YZ, XS\cong ZS and \angle X\cong \angle Z.

Step-by-step explanation:

Given information: YS is the perpendicular bisector of XYZ.

In triangle YXS and triangle YSZ,

\angle SYX=\angle SYZ                 (YS is the perpendicular bisector of XYZ)

YS=YS                                            (Common side, Reflexive property)

\angle YSX=\angle YSZ=90^{\circ}   (YS is the perpendicular bisector of XYZ)

By ASA postulate,

\triangle SYX\cong \angle SYZ

The corresponding parts of congruent triangles are congruent. so,

XY\cong YZ

XS\cong ZS

\angle X\cong \angle Z

(-5,-1), m=-5/4 I'm using that as a fraction
inessss [21]
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
