#1. Joseph wants to find the side length of a square that has an area of 150
adell [148]

Answer:

The answer is irrational

Step-by-step explanation:

we know that

The area of a square is given by the formula

A=b^2

where

b is the length side of the square

In this problem we have

A=150\ ft^2

substitute in the formula

b^2=150

take the square root both sides

b=\sqrt{150}\ ft\\

simplify

b=5\sqrt{6}\ ft

Remember that

A <u><em>Rational Number</em></u> is a number that can be made by dividing two integers

so

The length side is not a integer

therefore

The answer is irrational

If P(A)=0.4, P(A and B)=0.2,and P(A or B)=0.5, What is P(B)
Vladimir [108]

Answer:

\boxed{\ P(B)=0.3 \ }

Step-by-step explanation:

Hi,

We know that

P(A or B)=P(A)+P(B)-P(A and B)

so P(B)= P(A or B) - P(A) + P(A and B)

so

P(B) = 0.5 - 0.4 + 0.2 = 0.3

thanks
