Based on the results shown in the table, what is the probability that the coin Jillian picks will be a quarter

Jillian Picked Coins From Her Piggy Bank And Recorded The Number Of Coins In The Table Below.Based On

Answers

Answer 1

Answer:

1/8

Step-by-step explanation:

There are 24 coins total. 3 of them are quarters. So Jillian has a 3 in 24 chance of picking up a quarter. Simplifying 3/24 we get 1/8

Answer 2

The probability of randomly picking a quarter is P = 0.125

How to get the probability?

If we assume that all the coins have the same probability of being randomly picked, the probability of picking a particular type of coin is equal to the quotient between the number of coins of that type that we have, and the total number of coins.

In this case, we have 3 quarters, and a total of:

T = (6 + 7 + 8 + 3) = 24

Then the probability of randomly picking a quarter is:

P = 3/24 = 0.125

a home mortgage for a home that costs $672096 with a 4% interest rate for 24 years. How much is the monthly payment for the mortgage with the interest?

Answers

9514 1404 393

Answer:

  $3633.96

Step-by-step explanation:

The monthly payment is given by the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

monthly payment for principal P at annual rate r for t years.

  A = $672096(0.04/12)/(1 -(1 +0.04/12)^(-12·24)) = $3633.96

The monthly payment for the mortgage is $3633.96.

There are 3 squares between them.

please please help me find the volume and surface area i’ll give brainliest

Answers

Answer:

Area: 272ft²

Volume = 82.6236447189ft³

Step-by-step explanation:

AREA

The area of a square pyramid is found by combining the area of the base and the area of the triangular faces:

Area of base = area of square = L² = 8² = 16ft²

Area of one triangular face = (1/2)bh = (1/2)(8)(16) = 64ft²

There are four triangular faces so the total area = 16+4(64)= 16+256= 272 ft²

VOLUME

The volume of a square pyramid = (a²)(h/3), where a is the length of the base and h is the length from the top of the pyramid to the middle of the square.

We are given a, but not h. To find h, we must imagine a right-angled triangle within the pyramid, where 16ft is the hypotenuse, h is the height and the base is half of a (since the base is a square and the distance is from the edge to the middle). We can then use pythagorus's theorem to find h:

A²=B²+C²

16²=(8/2)²+h²

256=16+h²

h=√240

h=15.4919333848ft

Knowing h, we can find the volume:

Volume = (a²)(h/3)

Volume = (8²)(15.4919333848/3)

Volume = (16)(5.16397779493)

Volume = 82.6236447189ft³

Please help me anyone any other answers would be reported Which of the Following Lines Is An Example of An Assertion Read the following stories.Story 1A wealthy boy from a prominent family was always pampered and taken care of, but he never had anything to do. He started taking long walks along the gates out front of his mansion, so he could catch a glimpse of the excitement of the town. One day while walking, he spotted a townsman outside the gate who looked just like him. The wealthy boy told the townsman of all the wonders and riches of the mansion, and the townsman spoke of all the gossip and business of his working life. They decided it might be fun to trade places. The townsman loved his new role as a wealthy young man. He ate fine food, watched wonderful entertainment, and wore stunning clothing. The wealthy boy loved his new role as a townsman. He explored the city streets, enjoyed all the sights and smells of the markets, and met all sorts of interesting people. Eventually, though, life at the mansion grew complicated. The wealthy boy's family wanted him to take over the family business, and the townsman grew stressed with his new responsibilities. The wealthy boy was having trouble too. He was having a hard time earning a living, and he was tired and hungry from working all day. The wealthy boy returned to the mansion gates to see the townsman. Life had looked more enchanting on the other side of the gates, but they returned to their rightful roles and were all the more thankful for the blessings of their own lives.Story 2There were two twin girls who dreamed of being married. The one girl was very intellectual. She loved to read, explore, and learn new things. The other girl was very athletic, and she wanted a husband that shared her same interest in sport and activity. The intellectual twin decided to marry a man who had been an explorer. He had fascinating tales of his travels. The athletic sister decided to marry a very competitive, loving, romantic young man who had a passion for hunting and sport. Both twins were very pleased with their choices and fell much in love with their respective husbands. Eventually though, their love began to fade. The athletic twin grew tired of being in constant competition with her husband. The intellectual twin's brain was being exhausted by the constant learning and testing. The twin sisters decided they would trick their husbands and make a switch. At first, the intellectual sister loved all the attention and competition from her sporty new husband. The athletic sister loved learning of all sorts of new things and loved going on long walks and adventures with her new husband. Eventually, though, the twins were doubly exhausted by the pursuits of their new husbands. They longed to switch back to the familiarity and routine of their own lives. Even though their husbands seemed to be troublesome, they were familiar, and they shared the interests that were best suited to each twin sister.What is different about the plots of both stories? In Story 1, a wealthy boy and a poor townsman trade lives. In Story 2, two twin sisters trade husbands. In Story 1, a wealthy boy and a sporty twin trade lives. In Story 2, an intellectual twin marries a townsman. One story is about poor people becoming wealthy, and the other is about wealthy people becoming poor. One story is about two people who look nothing alike, and in the other story the characters look identical. evan has 4 chocolate bars with a total of 48 pices are in each bar Question 6 of 10 What is the slope of the line that contains the points (-2, 2) and (3, 4)?
