Given:

The number of male professors = 15.

The number of female professors = 9.

The number of male teaching assistants = 6.

The number of female teaching assistants = 12.

A person is selected randomly from the group.

Required:

We need to find the probability that the selected person is a professor or a male.

Explanation:

The total number of people in the group = 15+9+6+12 = 42

n(S) =The total number of people in the group

n(S)=42

Let A be the event that the selected person is a professor or a male.

The number of people who are professors or male = 15+9+6 = 30

n(A)= The number of people who are professors or male.

n(A)=30

Let P(A) be the probability that the selected person is a professor or a male.

P(A)=\frac{n(A)}{n(S)}P(A)=\frac{30}{42}P(A)=\frac{15}{21}=\frac{5}{7}

Final answer:

The probability that the selected person is a professor or a male is 5/7.

podryga [215]

Answer:

13.5 meters

Step-by-step explanation:

25 / 2 = 13.5

because if a human is 3 meters tall and cast 2 times the length of himself then if a building casts 25 meters then it should be 2 times less than its shadow.

In analyzing the given diagram which is a combination of two right angle triangle, the value of sin∠L is 5/13.

<h3>What is the value of sin∠L?</h3>

Given that angle ONM is a right angled triangle, we can find length of OM using the Pythagorean theorem.

c = √( a² + b² )

OM = √( 4² + 3² )

OM = √( 16 + 9 )

OM = √25

OM = 5

Next, angle OML is also a right angled triangle, we can get the hypotenuse LO.

c = √( a² + b² )

LO = √( OM² + ML² )

LO = √( 5² + 12² )

LO = √( 25 + 144 )

LO = √169

LO = 13

Now, to get sin∠L, we use the mnemonic: SOHCAHTOA

sinθ = opposite / hypotenuse

sin∠L = OM / LO

sin∠L = 5/13

Therefore, in analyzing the given diagram which is a combination of two right angle triangle, the value of sin∠L is 5/13.
