PLEASE HELP circle a has area 500in squared. the diameter of circle b is three times the diameter of circle a. esitmate the area

of circle b.
Mathematics

Answer:

Step-by-step explanation:

r and d are the radius and diameter of a, respectively.

area of a = πr² = 500 in²

r = √500/√π = 10√5/√π

d = 20√5/√π

radius of b = 3r = 30√5/√π

area of b = π(30√5/√π)² = π(4500/π) = 4500 in²

The faces of a tetrahedron die are numbered 1 to 4. if each of the 4 sides is equally likely to land down, what is the probabili
Hoochie [10]

The probability distribution for the face landing down =  4/15

<h3>What is the probability?</h3>

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

<h3>According to the given information:</h3>

If we assign 1 probability x

then 2 has probability  1/2 x.

Similarly,

then 3 has probability = 1/2((1/2)*x) = (1/4)*x

so

then 4 has probability = 1/2((1/4)*x) = (1/8)*x

These probabilities need to sum to 1.

Hence:

                x+\frac{1}{2} x+\frac{1}{4} x+\frac{1}{8} x=1

or equivalently

                   (15/8)*x = 1

                       x = 8/15

the probability distribution for the face landing down  = (1/2)*(8/15)

                                                                                         = 8/30

                                                                                         =  4/15

I understand that the question you are looking for is:

A tetrahedral die has four faces, numbered 1-4. If the die is weighted in such a way that each number is twice as likely to land facing down as the next number (1 twice as likely as 2, 2 twice as likely as 3, and so on) what is the probability distribution for the face landing down?

A parking spcae shaped like a paralelelogram has a base of 17 feet and a hiehgt of 9 feet, a car parked in the sapce is 16 feet
docker41 [41]

Answer:

57 Square Feet

Step-by-step explanation:

First, we determine the area of the parallelogram shaped parking space.

Area of a Parallelogram= base X Perpendicular Height

= 17X9=153 Square feet.

Next, we determine the area of the car packed on the space.

The space where the car is packed is 16 feet long and 6 feet wide.

This suggests a rectangular shape.

Area of the Packed Car

Length X Breadth=16X6= 96 Square feet.

Finally, we determine the area of the packing space not covered by the car.

Area not covered=Area of Parking Space - Area Covered by the Car

=153-96

=57 Square Feet
