#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
