In a class of 50 students, everyone has either a pierced nose or a pierced ear. The professor asks everyone with a pierced nose
Tems11 [23]

Answer:  3

Step-by-step explanation:

Let E be the event of that student pierces ear and N be the event of that student pierces nose.

Given: n(E\cup N=50)

n(E)=46\\\\n(N)=7

For any two event A and B, we have

n(A\cup B)=n(A)+n(B)-n(A\cap B)

Similarly , n(E\cup N)=n(E)+n(N)-n(E\cap N)

50=46+7-n(E\cap N)\\\\\Rightarrow\ n(E\cap N)=53-50=3

Hence, 3 students have piercings both on their ears and their noses.

If I have a triangle with a leg of 4 and a leg of 3 what is the length of the hypotenuse
Dmitrij [34]

Answer:

5

Step-by-step explanation:

To solve for hypotenuse we use the Pythagorean theorem:

a^2+b^2=c^2

In this theorem:

c= hypotenuse

a = leg

b = leg

Substitute into theorem:

4^2+3^2=c^2

16+9=c^2

25=c^2

(square root both sides)

5=c

Therefore the hypotenuse has a length of 5.

Please say thanks if correct :)
