Answer:

Pr =0.75

Step-by-step explanation:

Given

See attachment for wedge

Required

P(x > 5)

The sample space of the wedge is:

S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}

n(S) = 20

The outcomes greater than 5 are:

x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}

n(x>5) =15

So, the probability is:

Pr =\frac{(n(x>5)}{n(S)}

This gives:

Pr =\frac{15}{20}

Pr =0.75

A)
To be similar triangles have to have equal angles
triangle ZDB' 
1)angle Z=90 degrees
triangle B'CQ
1) angle C 90 degrees

angle A'B'Q=90
DB'Z+A'B'Q+CB'Q=180, straight angle
DB'Z+90+CB'Q=180
DB'Z+CB'Q=90

triangle ZDB'
DZB'+DB'Z=180-90=90

DB'Z+CB'Q=90
DZB'+DB'Z=90
DB'Z+CB'Q=DZB'+DB'Z
2)CB'Q=DZB' (these angles from two triangles ZDB' and B'CQ )
3)so,angles DB'Z and B'QC are going to be equal because of sum of three angles in triangles =180 degrees and 2 angles already equal.
so this triangles are similar by tree angles
b)
B'C:B'D=3:4
B'D:DZ=3:2
CQ-?
DC=AB=21
DC=B'C+B'D (3+4= 7 parts)
21/7=3
B'C=3*3=9
B'D=3*4=12
B'D:DZ=3:2
12:DZ=3:2
DZ=12*2/3=8
B'D:DZ=CQ:B'C
3:2=CQ:9
CQ=3*9/2=27/2

c)
BC=BQ+QC=B'Q+QC
BQ' can be found by pythagorean theorem

Jean bought 4 2 3 yards of fabric. How much is this in feet?
Misha Larkins [42]

Here we have to convert 423 yards into feet.

first let us find the basic relation between yard and feet

1 yard =3 foot

so applying this to our question we get,

423 yard =423*3 foot = 1269 feet

Answer 423 yards =1269 feet
