The histogram shows the number of items that customers bought during a trip to the grocery story 1 day. 400 customers took a trip to the grocery store that day. Which is the best estimate for the number who bought at least 50 items during their trip

Answers

The number of people who bought fewer than 30 items exists 204.

What is meant by histogram?

The frequency distribution of a few data points for one variable is represented graphically by a histogram. Heterogeneous "bins" or "range groups" are frequently used in histograms in order to categorize data and count the number of data points that are part of each bin.

Among graphing tools, the histogram is widely used. It is utilized to encapsulate discrete or continuous data that is measured on an interval scale. It is frequently employed as a convenient way to highlight the key characteristics of the data distribution.

As opposed to bar charts, which show categorical variables, histograms visualize quantitative or numerical data. Typically, a histogram's numerical data will be continuous (having infinite values).

Number of people who bought fewer than 30 items

= (0.14 + 0.12 + 0.24)400

= 0.51 x 400 = 204

Therefore, the correct answer is option B) 204.

What is factor?

A number that divides another number by itself with no residual is known as a factor. In other words, if multiplying two whole numbers results in the creation of a product, the numbers we are multiplying are factors of the product since the product is divisible by them. Division and multiplication are the two ways to discover factors. A number or other mathematical object is factorized or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort. One factorization of the polynomial x2 - 4 is 3 5, which is also a factorization of the number 15.

The diagram shows two proportional right triangles.
What is the perimeter of the larger triangle?

Answers

Answer:

48 units.

Step-by-step explanation:

Since the triangles are similar (proportional), their dimensions are increased at the same ratio at any point, which means their perimeter too. So the base of the larger triangle is twice as long as the base of the smaller triangle.

The perimeter of the smaller triangle is 10 + 6 + 8 = 24 units.

24 * 2 = 48. Because the ratio of increase is 2:1 from the bigger triangle to the smaller triangle.

[tex]A = \pi r^{2}[/tex]

In this question, pi is 3.14. The radius of a circle is half of its diameter. So:

[tex]\frac{34}{2} =17[/tex]

Plug these values into the equation:

[tex]A = 907.46[/tex]

The area of the circle is 907.46 inches squared.

A)Mark and Jada share 5 yards of ribbon equally. How much ribbon will each get
B)It takes half of a yard of ribbon to make a bow. How many bows can be made with 5 yards of ribbon?

Answers

A) Mark and Jada will each get 2.5 yards of ribbon.

Explanation:
Mark and Jada are sharing 5 yards of ribbon equally amongst 2 people, the two of the together. In order to solve the equation, you must divide the number of yards of ribbon by the number of people equally sharing it, which would be 5 divided by 2. 2 can not be multiplied by any non-decimal number to equal 5, so we can put down the number multiplied by 2 that is closest to 5, which would be 2, because 2 x 2 = 4. Subtracting 5 from 4 gives us 1. Since there are no remainders in our answer, the answer will be a decimal. So then we put a decimal in front of the 2, and add a 0 next to the 1 we got by subtracting 4 from 5, turning the 1 into a 10. 2 times 5 equals 10, so add a 5 to your answer and subtract 10 from 10. 10 - 10 = 0, so the answer is 2.5 yards of ribbon. You can check this answer by multiplying the 2.5 yards of ribbon in our answer by the 2 people who are equally sharing it, 2.5 x 2 = 5 yards of ribbon. So we can certainly conclude that Mark and Jada will be sharing 2.5 yards of ribbon.


B) Mark and Jada can make 10 bows with 5 yards of ribbon.

Explanation:
It takes half a yard of ribbon to make a bow, so we will need to find half of 1. 1 divided by 2 equals 0.5, so 0.5 yards of ribbon will be used for each bow. Now we need to find out how many bows can be made with 5 yards of ribbon. 5 divided by 0.5 equals 10, so the answer come out to be 10 bows. You can check your answer by solving 5 divided by 10, which equals 0.5. So we can safely conclude that 10 bows can be made with 5 yards of ribbon.

In a certain year, 31% of adults in a certain country viewed college education as essential for success. For the following ten-year period, this percentage increased by approximately 2. 6 each year.

The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by __

Answers

The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by the function P(x) = 31 + 2.6x.

What is the percentage function?

To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100. Percentage formula = (Value/Total value) × 100. Example: 2/5 × 100 = 0.4 × 100 = 40 per cent.

The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by the function:

P(x) = 31 + 2.6x

Where P(x) is the percentage of adults who viewed college education as essential for success x years after the first year, and x is the number of years after the first year.

The function shows that the percentage increase by 2.6 every year for x years after the first year, and the initial percentage is 31%.

This function is representing a linear trend since the coefficient of x is constant.

Hence, The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by the function P(x) = 31 + 2.6x.

A quadratic equation is an equation of the form ax2 + bx + c = 0, where a, b, and c are constants, and x is an unknown variable. The solution to such an equation is a value of x that will make the equation true.

To determine the number of seeds they donated, we have to write two equations and solve.

data;

Martha = 2x - 3Miguel = 2[2x - 3] = 4x - 6

The product of the seeds is (2x - 3)(4x - 6) = 8x² - 24x + 18

This can be written as

8x² - 24x + 18 = 50

Bonaly is one of the most decorated individuals in womens figure skating. She won medals in nearly every competition she entered. Bonaly did not start out as many young figure skaters do. For example, instead of learning to ice skate at a young age, Bonaly got her start in gymnastics. From the beginning, she showed promise as she began winning competitions for her tumbling routines. Her excellence and competitiveness paid off when, at the age of twelve, she won the World Championship in tumbling. From there, Bonaly turned her energies to ice-skating. Even at that young age, she was getting a late start in a sport that many skaters begin as early as age four. However, her strong gymnastics background helped fuel Bonaly's quick and early successes in competitive figure skating.Bonaly soon earned praise for her powerful and athletic performances. Her fierce determination to win was noted. Bonaly was a strong skater, performing extremely difficult moves and landing them consistently. However, she soon found herself battling against strongly held stereotypes of what a womens figure skater was supposed to be. This included ideas of a cool and aloof ice princess or as cute as a buttona perky ballerina on ice skates. To set herself apart, Bonaly chose to wear bold and bright costumes instead of the pastel colors favored by other female skaters. It was also suggested by some that because she was black and did not fit the typical womens ice skater model, Bonaly was judged more harshly than the other competitors. Bonaly felt she had to do more than any other competitor to be accepted and, perhaps even more importantly, win. Her growing perceptions of a double standard became even more visible during the 1994 World Championships in Japan. Bonaly earned a silver medal, losing to Japans Yuka Sato. A visibly upset Bonaly claimed that her routine was far more difficult than Satos. She not only refused to stand on the second place winners spot at the podium but also removed her silver medal from around her neck. Some say that she behaved poorly. To that, Bonaly responded, When you do sport, the rule is that you're supposed to play fair, to be a good athlete and good sport, I get it,""But I think at this point it was more an act of saying, 'OK, this is too much.' It happened many years in a row."Bonaly is probably most famous for a bold and daring stunt she performed during the 1998 Olympic Games held in Nagano, Japan. By this time, Bonaly was a clearly established skating champion; she had already won numerous honors for her skating, including winning the French Nationals nine times, as well as being a five-time European champion. She was also a three-time world silver medalist. The Nagano Olympics was Bonalys third time at the international winter sports competition. But she entered the games during a period when her skating performances that year were weaker than usual, due to an ongoing heel injury. The extent of Bonalys injury was reflected in her low scores. She realized that she would not earn a medal. So, she decided to do something special in her last routine, the freestyle skate. The something speciala backflipwas a feat she was already known for. It had already gotten her into trouble as the jump was banned by Olympic officials because of the danger. But, knowing that this would be her last Olympics, Bonaly decided to please the crowd and not the judges. In the middle of her routine, Bonaly abandoned her planned triple Lutza jump combined with three spinsand instead threw her arms overhead to do the back flip, landing successfully on one skate. Bonaly landed her flip cleanly and finished her program with no mistakes. The crowd went wild with applause and cheers.Although her feat did not win her a medal, it was a move that, given its risk and difficulty, made people remember her. Twenty years later, people who saw this famous jump still talk about it. Bonaly remains the only female skater in history to do this jump successfully in competition. Although still illegal to perform in Olympic competition, the flip has now been named The Bonaly. Bonaly will also be remembered for being a strong and outspoken woman of color in a sport that traditionally has few minorities. Her willingness to challenge traditional expectations for young female figure skaters has shown others that there are many different paths to success.
