A histogram is a rough illustration of how numerical values are distributed. Karl Pearson coined the phrase at the beginning.

A histogram is a visual representation of statistical data that makes use of rectangles to illustrate the frequency of data points over a range of successive numerical intervals of equal width. The independent variable and dependent variable are plotted along the horizontal axis and the vertical axis, respectively, in the most typical type of histogram.

A common tool for graphing is the histogram. It is employed to summarise continuous or discrete data that is measured on an interval scale. It is frequently used to provide a convenient manner of illustration for the main characteristics of the data distribution.

Therefore, the correct answer is both option c) and d) Range, because Flower Town is skewed and symmetric.

The standard deviation of the data set is  0.7.

First, calculate the mean of the data set:

(mean) = (2+1+1+2+2+3)/6 = 11/6 ≈ 1.8

Next, calculate the deviation of each data point from the mean:

2 - 1.8 = 0.2

1 - 1.8 = -0.8

1 - 1.8 = -0.8

2 - 1.8 = 0.2

2 - 1.8 = 0.2

3 - 1.8 = 1.2

Now square each deviation:

0.2² = 0.04

(-0.8)² = 0.64

(-0.8)² = 0.64

0.2² = 0.04

0.2² = 0.04

1.2² = 1.44

The sum of the squared deviations is:

0.04 + 0.64 + 0.64 + 0.04 + 0.04 + 1.44 = 2.84

To find the variance, we divide by the number of data points:

variance = 2.84/6 ≈ 0.4733

Finally, take the square root of the variance to get the standard deviation:

standard deviation = √(0.4733) ≈ 0.69

Therefore, the standard deviation of the data set {2,1,1,2,2,3} is approximately 0.7 (rounded to the nearest tenth).

There are 8 different trips that can be made from City X to City Z, passing through City Y.

To find the number of different trips that can be made from City X to City Z, passing through City Y, we can use the multiplication principle of counting.

First, we need to choose one of the 2 major roads from City X to City Y. Then, for each of these roads, there are 4 major roads from City Y to City Z, and we need to choose one of these roads.

By the multiplication principle of counting, the total number of different trips from City X to City Z, passing through City Y, is the product of the number of choices at each stage. Thus, we get:

Number of different trips = Number of roads from City X to City Y x Number of roads from City Y to City Z

= 2 x 4

= 8

The equation representing the scenario is 1.5x + 8 = 20 and the possible number of rides is 8.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, The cost of entering the fair is $8 and the cost of each ride is $1.50.

Let, The number of rides be 'x'.

Therefore, The equation can be formed as, 1.5x + 8 = 20.

Now, To obtain the number of rides,

1.5x + 8 = 20.

1.5x = 12.

x = 12/1.5.

Answer:

CF = 7.2 cm

Step-by-step explanation:

given 2 chords intersecting inside a circle , then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

BF ×FC = DF × EF

10x = 8 × 9 = 72 ( divide both sides by 10 )

x = CF = 7.2 cm

42 adult tickets and 421 children tickets were purchased for the field trip, based on the given information that the total cost of the tickets was $995 and the children tickets cost $11 while the adult tickets cost $13, and the number of children tickets purchased was one more than ten times the number of adults tickets purchased.

Let's use variables to represent the unknown quantities in the problem:

Let x be the number of adult tickets purchased

Then the number of children tickets purchased is 10x + 1 (since it is one more than ten times the number of adults tickets purchased)

Using these variables, we can set up an equation based on the total cost of the tickets:

13x + 11(10x + 1) = 995

Simplifying and solving for x, we get:

23x + 11 = 995

23x = 984

x = 42.7826087 (rounded to 9 decimal places)

Since we can't purchase a fraction of a ticket, we'll round x down to the nearest whole number, which means 42 adult tickets were purchased. Then the number of children tickets purchased is:

10x + 1 = 10(42) + 1 = 421

So, 42 adult tickets and 421 children tickets were purchased.

The measure of x is 14, by using the definition of secants.

A straight line that intersects a circle in two points is called a secant line. A chord is the line segment that joins two distinct points of the circle. A chord is in a unique secant line and every secant line defines a unique chord. In geometry, a secant is a line that cuts any curve in at least two different points.

Given that, two secants are intersecting inside the circle making two arcs measuring 55° and 75° and an angle measuring 3x+23

We know that,

If two secants intersect inside a circle, then the measure of the angle formed is equal to half the sum of the measures of the intercepted arcs.

Therefore,

3x+23 = 1/2[55° + 75°]

3x+23 = 1/2 × 130

3x+23 = 65

Since Hank is allergic to chocolate, he cannot eat Reese's, Snickers, Hershey's bars, or any other type of chocolate candy.

Therefore, the only candy that Hank can eat is the Sour Patch Kids and Skittles.

The total number of Sour Patch Kids that Hank has is 5.

The total number of Skittles that Hank has is 6 packs, or 6 * the number of Skittles in one pack (let's assume it's 10 Skittles per pack). So, the total number of Skittles that Hank has is 6 * 10 = 60.

Adding the number of Sour Patch Kids and Skittles, the total number of candy that Hank can eat is 5 + 60 = 65.

The total amount of candy that Hank has is 8 Reece's + 12 Snickers + 5 Sour Patch Kids + 4 Hershey's bars + 6 packs of Skittles = 8 + 12 + 5 + 4 + 6 * 10 = 8 + 12 + 5 + 4 + 60 = 89.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

a. The oldest grandchild got the most ice cream.

b. Let's first calculate the fraction of the ice cream that was left after serving the youngest and middle grandchild.

The youngest grandchild received 1/5 of the ice cream, which means 4/5 was left.

Then the middle grandchild got 1/4 of the remaining 4/5, which is 1/5. So 4/5 - 1/5 = 3/5 of the ice cream is left.

Now, if Grandpa Mick serves himself the same amount as the second grandchild (1/4 of the original amount), he will be taking 1/4 of 1/5 of the original amount, which is 1/20.

Step-by-step explanation:

Step-by-step explanation:

Let's call the number of purple counters "x". This means that the number of blue counters is x - 78, and the number of white counters is 18x.

According to the ratio, the sum of the number of purple and blue counters is 16x + (x - 78) = 17x - 78.

And the sum of all counters is 16x + 18x + 3x = 37x.

Knowing that the sum of all counters is the same, we can set the two sums equal to each other:

37x = 17x - 78 + 37x

So, we have:

74x = 17x - 78 + 37x

57x = -78

x = -78/57

Since x can't be negative, we have to reject this solution.

However, the number of white counters can be found by multiplying 18 by the number of purple counters:

18 * x = 18 * (x/57) = (18/57) * x = (18/57) * 78 = 72

Therefore, there are 72 white counters in the bag.

(1) The hypothesis is stated that completing a 2-week mindfulness training course

(2) The type of study design this is randomized controlled trial.

(3) The choice of the study type is randomized controlled trial is justified. (4) The list of the two variables with their operational definitions is 2-week mindfulness training course and GRE scores.

(5) Yes, this study demonstrate that the relationship between the two variables is causal

In a study conducted by Mrazek et al. (2013), it was found that students who completed a 2-week mindfulness training course scored higher on the GRE than those who did not participate in the training.

The hypothesis of this study is that completing a 2-week mindfulness training course will result in higher scores on the GRE compared to those who do not complete the training.

This study design is a randomized controlled trial. In this type of study, participants are randomly assigned to either a treatment or control group, and the effects of the treatment are compared to the effects of no treatment (or a placebo). In this case, the treatment group received the 2-week mindfulness training course, while the control group did not.

The choice of study type as a randomized controlled trial is justified because it allows for the comparison of two groups while minimizing the effects of confounding variables. Random assignment to groups helps to ensure that any differences in outcomes between the groups are due to the treatment and not some other factor.

The two variables in this study are the completion of the 2-week mindfulness training course and GRE scores. The operational definition of completion of the training course is that participants in the treatment group attended all sessions of the 2-week course. The operational definition of GRE scores is the score that participants received on the exam.

This study does suggest a causal relationship between completion of the mindfulness training course and higher GRE scores. The randomized controlled trial design helps to reduce the effects of confounding variables, making it more likely that any observed differences in outcomes between the treatment and control groups are due to the treatment.
