HELP ME PLZ DUE TODAY PICTURE IS ABOVE

Which property is being demonstrated?

quotient of powers property
power of a product property
product of powers property
power of a quotient property

Answers

Answer:

A.

Step-by-step explanation:

We see a fraction. A fraction means a division, and the result of a division is called a quotient. We know we have a quotient.

We have two choices with "quotient."

A. quotient of powers property

D. quotient of powers property

We need to choose A or D.

A. quotient of powers means a division of powers. That is what we see with the fraction. A power in the numerator, and a power in the denominator. We have a division of powers, so it is a quotient of powers.

D. power of a quotient. This is take a fraction which is a quotient, and raise the entire fraction to an exponent. This is not what we have.

Answer: A.

The mean age of 5 people in a room is 31 years.
A person enters the room.
The mean age is now 30.
What is the age of the person who entered the room?​

Answers

Answer:

25 year

Step-by-step explanation:

Mean = sum/no. *of observations

Initially, number of people = 5 & let the sum of their ages be S.

=> 31 = S/5

=> 155 = S

When one more entered, number = 6. Let his age be 'a'.

Sum of ages = S + a = 155 + a

=> 30 = (155 + a)/6

=> 180 = 155 + a

=> 25 = a
