Given figure is a trapezoid.

Perimeter = 6 + 3.6 + 2 + 2.6 mm = 14.2 mm

Area = 1/2 * ( 6 + 2 ) * 2.3 sqmm = 9.2 mm

A and B are two events. Let P(A)=0.5 , P(B)=0.9 and P(A and B)=0.15 .

Nana76 [90]

Answer:

option-C

Step-by-step explanation:

we are given

Let P(A)=0.5

P(B)=0.9

P(A and B)=0.15

we know that

$P(A|B)=\frac{P(Aand B)}{P(B)}$

now, we can plug values

$P(A|B)=\frac{0.15}{0.9}$

$P(A|B)=0.16666$

but we have

P(A)=0.5

we can see that both are not equal

$P(A|B)\neq P(A)$

so, A and B are not independent

so, option-C........Answer

PLEASE HELP W/ THIS ASAP!!

Answer:

- 1.375

Step-by-step explanation:

Each dot is worth -1/8 of a unit when moving left.

So the coordinates of the dark dot are - 1 and - 3/8

or - 1.375 . The word coordinates (plural) bothers me. It all depends on how you have been asked to represent these points. Another possibility is (-1.375,0). You have to choose from the examples you have been given. I wouldn't do that because you have not been given and xy graph.
