140 degrees is the answer.

Tangent touches the circle at 90 degrees. Since angles in a triangle add up to 180 degrees, 180 - (90+50)

angle BAD = 40

Supplementary angles add up to 180 degrees, so 180-40

= 140 degrees

Hope it helps :)

Match each description with its symbolic representation.

dezoksy [38]

Answer:

i) P(A) ; The probability that event A occurs

ii) P(AB) ; The probability that both event A and event B occur

iii) P(AUB) ; The probability that either event A or event B occurs

iv) 1 - P(ANB) ; The probability that both events A and B do not occur together, but either may occur by itself

v) 1- P(AUB) ; The probability that neither event A or event B occurs

vi) P(AIB) ; The probability that event A occurs given the fact that event B occurs

Step-by-step explanation:

P(A) simply represents the probability that an event A will occur. This event could be passing an examination, having snow in summer, arriving to work on time and so forth.

ii)

P(AB) is simply the probability that both event A and event B do occur. This is usually given by the product of the individual probabilities. Event A could be rolling a 6 in one throw of a fair die while B could be the event that a fair coin lands heads in a single toss.

iii)

P(AUB) refers to the probability that either event A or event B occurs. This is read out as the probability of A union B. This is usually given by the sum of the individual probabilities.

iv)

1 - P(ANB) is the probability that both events A and B do not occur together, but either may occur by itself. P(ANB) is the probability that both events A and B occur together. This is read out as the probability of A intersection B. Therefore implying that 1 - P(ANB) is simply the probability that either event A or B occurs but A and B can not occur together.

1- P(AUB) refers to the probability that neither event A or event B occurs. Earlier we defined P(AUB) as the probability that either event A or event B occurs. 1- P(AUB) simply the complement of P(AUB).

vi)

P(AIB) refers to the probability that event A occurs given the fact that event B occurs. This is a conditional probability event which evaluates the likelihood of an event A occurring given that an associated event B has already occurred

What is the remainder of the following division problem? x startlongdivisionsymbol x 1 endlongdivisionsymbol. minus x to get a r

irga5000 [103]

The remainder of the expression x/(x + 1) is a negative one. Then the correct option is D.

<h3>What is division?</h3>

The division means the separation of something into different parts, sharing of something among different people, places, etc.

The expression is given below.

$\rm \rightarrow \dfrac{x}{x+1}$

Add and subtract 1 in the numerator, then we have

$\rm \rightarrow \dfrac{x+1-1}{x+1}\\\rm \rightarrow 1 -\dfrac{1}{x+1}$

Then the remainder will be a negative one.

More about the division link is given below.

Convert polar equation to rectangular coordinates θ = − (9π/ 2)

yan [13]

Visualize pi/2 as 90° on the unit circle. this has no real component, only imaginary. same for 3pi/2, or -pi/2 as shown in this equation:

$- \frac{ \pi}{2} = 0 - i$

as you move around the unit circle, you'll find that 9pi/2 is the same angle as pi/2.

Thus, the rectangular coordinates are:
$- \frac{9\pi}{2} = 0 - i$
