Is the number of members of Club X greater than the number of members of Club Y ? (1) Of the members of Club X, 20 percent are a

Oliga [24]

Answer:

Yes

Step-by-step explanation:

The 20% of members of club X that are also members of club Y can be written as: P(Y/X) = 20% (that is, the probability of belonging to Y given that it belongs to X)

The 30% of members of club Y that are also members of club X can be written as: P(X/Y) = 30% (that is, the probability of belonging to X given that it belongs to Y)

The formula of conditional probability of A given B is

P(A/B) = (A∩B) / P(A)

Where (A∩B) is the probability that both events A and B occur and P(A) is the probability of A.

Based on that, we can write,

P(Y/X) = P(Y∩X) / P(X) = 20 % = 0.2

P(X/Y) = P(Y∩X) / P(Y) = 30 % = 0.3

Clearing P(Y∩X) of both equations and equalizing,

P(Y/X).P(X) = P(X/Y).P(Y)

Moving terms ,

P(X) / P(Y) = P(X/Y) / P(Y/X) = 0.3 / 0.2 = 1.5

That is, P(X) is 1.5 times P(Y), which means that the amount of members of X is greater than the members of Y.

What is the measure of angle C?

quester [9]

Answer:

C = 10.39

Step-by-step explanation:

We know that the sin of an angle is the opposite side over the hypotenuse

sin C = 22/122

sin C = 11/61

Take the inverse sin of each side

sin ^-1 (sin C) = sin ^-1 ( 11/61)

C = 10.38885782

To the nearest hundredth

C = 10.39

A circle has a circumference of 615.44 units. What is the radius of the circle?

Mama L [17]

Answer:

The radius of the circle is $r=98\ units$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=615.44\ units$

assume

$\pi=3.14$

substitute and solve for r

$615.44=2(3.14)r$

$r=615.44/6.28$

$r=98\ units$

<h2>Answer:</h2>

20. $\angle3$

21. $\angle F$

22. $\angle BHF$

<h2>Additional information:</h2>

Vertical angle means opposite angles.

It states that If two lines intersect each other, then the vertically opposite angles are equal.

For eg :- In this diagram,

$\angle1 = \angle3$

$\angle4= \angle6$

Linear pair means to form 180°.

It states that the two axioms above together is called the Linear Pair Axiom.
If the sum of two adjacent angles is 180°, if non-common arms of the angles form a line.

For eg :- In this diagram,

$\angle1 + \angle2 = 180 \degree$

$\angle4 + \angle5= 180 \degree$
