A certain system can experience three different types of defects. Let Ai (i = 1,2,3) denote the event that the system has a defe
denis-greek [22]

By definition of conditional probability,

P(A_2\mid A_1)=\dfrac{P(A_1\cap A_2)}{P(A_1)}

The inclusion-exclusion principle tells us

P(A_1\cap A_2)=P(A_1)+P(A_2)-P(A_1\cup A_2)=0.12+0.08-0.14=0.06

Then

P(A_2\mid A_1)=\dfrac{0.06}{0.12}=0.5000

Find m∠CXY<br> Please help with this, this is for my test review!!!
Murljashka [212]

Answer:

137°

Step-by-step explanation:

All angles in a triangle add up to 180° always.

Now imagine the two smaller shapes as a bigger triangle, CED.  The measure of angle CED is 89°, and CDE is 48°.  Do the math, and angle DCE is 43°.

But notice how the corresponding sides of the two smaller shapes are congruent.  (CX=XE, and DY=YE)  Meaning, the measure of angle C is equal to the measure of angle YXE.

We're almost there.  CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180.  180-43 = 137°.

Ayuden por favor. Es de matemáticas! La equation está en la foto
DanielleElmas [232]

Answer:

A = 0.65

B = 3.304

C = 6.07

Step-by-step explanation:

You have to subtract to the final result the initial one and divide it for the number of segments. Then, for every segment you add the number you found, for example:

Value of a segment:

\frac{1 - 0.5}{10}  = 0.05

Value of A:

0.5 + 3 \times 0.05 = 0.65
