Try this option:
1. rule: P(E)+P(not E)=1.
2. according to the rule above
P(not E)=1-P(E)=1-0.3=0.7;
P(E)=1-P(not E)=(100-65)%=35%.
Answer:
30/125
Step-by-step explanation:
30 divided by 125 is the same
Answer:
answer id the 4th degree angle
Step-by-step explanation:
WXYZ is a rhombus with vertices W(0,4b), X(2a,0), Y(0,-4), Z(-2,0). You can see thap points W and Y lie on the y-axis and points X and Z lie on the x-axis. Then the centre of the rhombus is origin, thus W and Y are symmetric about the origin. Then b=1 and point W has coordinates (0,4). Similarly points X and Z are symmetric about the origin and a=1, hence X(2,0).
Let KLMN be middlepoints of segments WX, XY, YZ, ZW, respectively. Then
.
Now find the vectors
,
,
and
:
that means that
.
Similarly,
,
,
.
You prove that KLMN is a recctangle.
