Step-by-step explanation:

<h2>______________________</h2>

The sum of angle at a point is 360° so...

310° + a = 360°

a = 360° - 310°

a = 50°

Now...

here b and 180° are supplementary angle so ....

b = 180° - 80°

b = 100°

Again...

The sum of all angle of triangle is 180° so...

100° + 50° + c = 180°

150° + c = 180°

c = 180° - 150°

c = 30°

<h2>______________________</h2>

Hence...the value of a is 50° , b is 100° and c is 30°...

Answer:

a is 50

b is 100

and c is 130

Step-by-step explanation:

1) the reason why a is 50 because a circle has a constant angle which is 360 so we just need to subtract 360 by 310 to find out the missing angle to complete the entire circle.

2) a straight angle has a constant angle which is 180 degrees and now we have the given angle 80 so to complete the straight angle we just need to subtract 180 to 80.

3) now as we've found a, which is 50 degrees, we now also know that a straight angle is 180 degrees so just subtract 180 by 50 so we get 130.

I'm sorry I'm really bad at explanations but I tried and I hope it helps.

thank you

Graph the following lines and using the graph determine several values of x for which the graph is positive (negative): y=−4x+3

True [87]

Answer:

Step-by-step explanation:

Given line is,

y=-4x+3

when, x=-1 , y=-4(-1)+3=4+3=7

when, x=0 , y=-4(0)+3=0+3=3

when, x=1 , y=-4(1)+3=-4+3=-1

So, we got the points (-1,7) , (0,3) , (1,-1)

Now, putting the points in the graph and adding them , we will get the graph of given line.

Please check image for the graph.

Now for the second part-

The graph is positive means- it will be above the x-axis, that is y value will be positive.

From the graph we can see that, if x<0 , then y is positive.

So, any value of x which is less than 0 , will give the positive graph here.

A hospital’s financial reimbursement payor mix indicates 35% of the patients have Medicare and 15% have Medicaid. Of those who h

Damm [24]

Using conditional probability, it is found that there is a 0.035 = 3.5% probability that a hospital patient has both Medicare and Medicaid.

<h3>What is Conditional Probability?</h3>

<em>Conditional probability</em> is the <u>probability of one event happening, considering a previous event</u>. The formula is:

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

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, the events are:

Event A: Patient has Medicare.

Event B: Patient has Medicaid.

For the probabilities, we have that:

35% of the patients have Medicare, hence $P(A) = 0.35$ .

Of those who have Medicare, there is a 10% chance they also have Medicaid, hence $P(B|A) = 0.1$ .

Then, applying the <em>conditional </em>probability:

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

$0.1 = \frac{P(A \cap B)}{0.35}$

$P(A \cap B) = 0.35(0.1)$

$P(A \cap B) = 0.035$

0.035 = 3.5% probability that a hospital patient has both Medicare and Medicaid.
