Answer:

47 degrees

Step-by-step explanation:

Due to the Exterior Angle Theorem, you know that the exterior angle is equal to the sum of the opposite two interior angles:

$2x-2=x+45\\x=47$

Answer:

x = 47

Step-by-step explanation:

The exterior angle is the sum of the opposite interior angles for a triangle

2x-2 = x + 45

Subtract x from each side

2x-2 -x = x+45-x

x-2 = 45

Add 2 to each side

x-2 +2 = 45+2

x = 47

Antonio graphs these questions and finds that the lines intersect at a single point (-5,0.25)

lisov135 [29]

Given equations : Equation A: 4y -3x =16 and

Equation B: -x-8y =3.

We are given a point (-5,0.25) plugging it in first equation

4(0.25) -3(-5) =16

1+15 =16.

16 =16 : Satisfies first equation.

We are given a point (-5,0.25) plugging it in second equation.

-(-5)-8(0.25) =3.

5 - 2 = 3.

3=3.

<h3>Therefore, they are the only values that make both eqautions true.</h3>

baye's theorem certain test for cholera gives 5% false positives, and 12% false negatives. If the test gives correct results 93%

jekas [21]

Answer:

The percentage of people having cholera is 89.19%.

Step-by-step explanation:

According to the Bayes' theorem the total probability of <em>A</em> is:

$P(A)=P(A|B)P(B)+P(A|B^{c})P(B^{c})$

Let <em>X</em> = a person has chorea and <em>Y</em> = the test is positive.

Given:

$P(X^{c}|Y)=0.05\\P(X|Y^{c})=0.12\\P(Y)=0.93$

The value of $P(X|Y)$ is:

$P(X|Y)=1-P(X^{c}|Y)=1-0.05=0.95$

Compute the value of P (X) as follows:

$P(X)=P(X|Y)P(Y)+P(X|Y^{c})P(Y^{c})\\=(0.95\times0.93)+(0.12\times(1-0.93))\\=0.8835+0.0084\\=0.8919$

The percentage of people suffering form cholera is, 0.8919 × 100 = 89.19%.

Thus, the percentage of people having cholera is 89.19%.
