Alicia is sewing a rectangle bedspread that measures 72 inches by 60 inches. The bedspread is red with a gold circle 18 inches i

Natalija [7]

Answer:

$4,066\ in^{2}$

Step-by-step explanation:

we know that

The area of the bedspread that is red is equal to the area of rectangle minus the area of the circle

step 1

Find the area of rectangle

The area is equal to

$A=72*60=4,320\ in^{2}$

step 2

Find the area of the circle

$A=\pi r^{2}$

we have

$r=18/2=9\ in$ ----> the radius is half the diameter

assume

$\pi=3.14$

substitute

$A=(3.14)(9)^{2}$

$A=254.34\ in^{2}$

step 3

Find the area of the bedspread that is red

Find the difference of the areas

$4,320\ in^{2}-254.34\ in^{2}=4,066\ in^{2}$

P(A) = 0.8, P(B) = 0.55 and P(A and B) = 0.35.<br> What is P(A or B)?

Likurg_2 [28]

<h3>Answer: 1</h3>

Work Shown:

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

P(A or B) = 0.8 + 0.55 - 0.35

P(A or B) = 1.35 - 0.35

P(A or B) = 1

A probability of 1 means there is 100% certainty the event happens. This must mean that there are only possible outcomes are: either event A happens, or B happens, or possibly both A and B happen simultaneously.
