The five-number summary for the given set of sample data is
1. Minimum value = 6
2. Lower quartile Q1 = 35
3. Median = 52
4. Upper quartile Q3 = 75
5. Maximum value = 100
How do calculate the five-number summary (min, Q1, median, Q3, max) for a given sample data?The formulas for finding a five-number summary of a given set of n data values are:
Minimum value = least value from the entire data set
Maximum value = highest value from the entire data set
Lower quartile Q1 = 1/4 (n + 1)th term
Upper quartile Q3 = 3/4 (n + 1)th term
Median = middle term of the data set.
To find the median:
Arrange the given data in the ascending orderIf the n value is odd then the median lies at (n+1)/2 th termIf the n value is even then the median lies in between the two data values obtained by n/2 th term and the (n/2 + 1) th term.Calculation:The given set of sample data is
{6, 20, 24, 25, 26, 35, 40, 41, 43, 48, 50, 52, 53, 59, 66, 71, 72, 75, 79, 80, 83, 89, 100}
So, the sample size n = 23
The data is arranged in ascending order as
{6, 20, 24, 25, 26, 35, 40, 41, 43, 48, 50, 52, 53, 59, 66, 71, 72, 75, 79, 80, 83, 89, 100}
Then,
Minimum value = 6
Maximum value = 100
Calculating the median:
Since n = 23 is an odd number then the median lies at (n + 1)/2 th term
So,
Median = (23 + 1)/2 = 24/2 = 12th term
In th given set of data values, the 12th term is 52
∴ Median = 52
Calculating the lower quartile Q1:
Lower quartile Q1 = 1/4 (n + 1)th term
⇒ Q1 = 1/4(23 + 1)th term
⇒ Q1 = 1/4 × 24 = 6th term
From the given data set, the 6th term is 35
∴ Q1 = 35
Calculating the upper quartile Q3:
Upper quartile Q3 = 3/4(n + 1)th term
⇒ Q3 = 3/4(23 + 1)th term
⇒ Q3 = 3/4 × 24 = 18th term
From the given data set 18th term is 75
∴ Q3 = 75
Then the five-number summary for the given data set is {min = 6; Q1 = 35; median = 52; Q3 = 75; max = 100}

Clarence walks 3.1 miles around Lake Johnson every day for five days.
If it takes him a total of 6 hours to walk the 15.5 miles, what is his
average time per day?
minutes per day.
Answer:
Average time per day = 1.2 hours per day
Average time per day = 72 minutes per day
Step-by-step explanation:
To find Clarence's average time per day, we need to divide the total time he takes to walk the 15.5 miles by the number of days he walks, which is five.
Let's calculate his average time per day:
Average time per day = Total time / Number of days
Since Clarence takes a total of 6 hours to walk the 15.5 miles, we'll divide 6 by 5 to find his average time per day:
Average time per day = 6 hours / 5
Average time per day = 1.2 hours per day
To convert hours to minutes, we'll multiply the average time per day by 60:
Average time per day = 1.2 hours * 60 minutes
Average time per day = 72 minutes per day
Therefore, Clarence's average time per day is 72 minutes.

The radius of a circle is 1 foot. What is the length of a 90° arc?
90°
r=1ft
Give the exact answer in simplest form.
According to the given data the length of a \(90^{0}\) arc is \(\pi /2\) or approximately \(1.57\) feet.
What is meant by length of arc?In geometry, the length of an arc is the distance along the curved line that makes up the arc. It is a measure of the "length" of a portion of a circle's circumference, and it is usually expressed in the same units as the circle's radius.
According to the given information:
The length of a \(90^{0}\) arc in a circle with radius \(1\) foot can be calculated using the formula:
Length of arc = (angle/\(360\)) x \(2\pi r\)
where angle is the central angle of the arc in degrees, r is the radius of the circle, and \(\pi\) is a mathematical constant approximately equal to \(3.14159\).
Substituting the given values, we have:
Length of arc = (\(90/360\)) x \(2\pi(1 ft)\)
Length of arc = \((1/4)\) x \(2\pi ft\)
Length of arc = \(\pi /2 ft\)
Therefore, the length of the \(90^{0}\) arc is \(\pi /2 feet\) or approximately \(1.57 feet\)

the length of the 90° arc is π/4 feet or approximately 0.785 feet
What is arc of circle?
In geometry, an arc of a circle is a portion of the circle's circumference. It is defined by two endpoints and all points along the circle between those endpoints. The measure of an arc is typically given in degrees or radians and can be used to calculate various properties of the circle, such as its length, area, and sector angles.
The formula for the length of an arc is:
L = (θ/360) × 2πr
where L is the length of the arc, θ is the central angle of the arc in degrees, and r is the radius of the circle.
In this case, θ = 90° and r = 1 ft, so we have:
L = (90/360) × 2π(1) = (1/4) × π = π/4
Therefore, the length of the 90° arc is π/4 feet or approximately 0.785 feet (rounded to 3 decimal places).

Answer:
1. h = 900/b
2. 36
Step-by-step explanation:
The area of a rectangle is given by:
A = length x width
In this case, we know that the area of the pet door is 900 square centimeters, so we can write:
900 = h x b
To solve for the height in terms of the width, we can divide both sides by b:
h = 900/b
Now, if the base of the pet door is 25 centimeters wide, we can substitute b = 25 into the equation above to find the height:
h = 900/25 = 36
Therefore, the height of the pet door would be 36 centimeters if the base is 25 centimeters wide.

Write the equation of a line that is parallel to y = 3x and goes through (-2, 1).
Answer:
y = 3x + 7
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 3x. Its slope is 3. A line parallel to this one will also have a slope of 3.
Plug this value (3) into your standard point-slope equation of y = mx + b.
y = 3x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-2, 1). Plug in the x and y values into the x and y of the standard equation.
1 = 3(-2) + b
To find b, multiply the slope and the input of x (-2)
1 = -6 + b
Now, add 6 to both sides to isolate b.
7 = b
Plug this into your standard equation.
y = 3x + 7
This equation is parallel to your given equation (y = 3x) and contains point (-2, 1)

Find cott given that cost =

Please quickly
Recall that
cos²(x) + sin²(x) = 1
for any x. Also, remember that cotangent is defined as
cot(x) = cos(x) / sin(x)
We're given that cos(t ) = 5/13 and cot(t ) < 0, which means sin(t ) must be negative. So when we solve for sin(t ) in the first relation, we have to take the negative square root:
sin²(t ) = 1 - cos²(t )
sin(t ) = -√(1 - cos²(t ))
sin(t ) = -√(1 - (5/13)²) = -12/13
Then
cot(t ) = (5/13) / (-12/13) = -5/12
One brand of cola co fizz is sold in packs of 4*500ml for 2.50 another brand colo is sold in packs of 10 330mlfo $2 which brand is more expensive
Based on the given information, the second brand, Cola, is the more affordable option in terms of cost per milliliter compared to Co Fizz.
To determine which brand of cola is more expensive, we need to compare the cost per unit volume for each brand.
For the first brand, Co Fizz, a pack contains 4 bottles, and each bottle has a volume of 500 ml. The cost of the pack is $2.50. Therefore, the total volume in a pack is 4 * 500 ml = 2000 ml. To find the cost per milliliter (ml), we divide the total cost by the total volume: $2.50 / 2000 ml = $0.00125 per ml.
For the second brand, Cola, a pack contains 10 bottles, and each bottle has a volume of 330 ml. The cost of the pack is $2. Therefore, the total volume in a pack is 10 * 330 ml = 3300 ml. To find the cost per milliliter (ml), we divide the total cost by the total volume: $2 / 3300 ml ≈ $0.000606 per ml.
Comparing the two brands, we can see that the cost per milliliter for Co Fizz is $0.00125, while the cost per milliliter for Cola is approximately $0.000606.
Since the cost per milliliter for Co Fizz is higher than the cost per milliliter for Cola, it can be concluded that Co Fizz is more expensive in terms of price per unit volume.

The loss percentage is 91%.Given that Venessa bought 80 apples for 4$, out of these apples, 25% were rotten and had to be thrown away. Venessa sold the remaining apples at 6 cents per apple.To calculate the profit or loss percentage, we need to determine the cost price, selling price, and the number of apples sold.
Cost price (CP) = 4 $.Selling price (SP) = 80 × 0.75 × 6 cents= 36 cents = 0.36 $.Now, let's calculate the profit.Profit = SP – CP= 0.36 $ – 4 $= – 3.64 $Loss = CP – SP= 4 $ – 0.36 $= 3.64 $.
Therefore, Venessa incurred a loss of $3.64 when she sold 80 apples at 6 cents per apple.Now let's calculate the loss percentage Loss Percentage = (Loss / CP) × 100= (3.64 / 4) × 100= 91%.
Therefore, the loss percentage is 91%.Note: If the result obtained after the subtraction of SP from CP is negative, it means there is a loss, and the percentage of loss can be calculated by (loss/CP) × 100.

a study studied the birth weights of 1,999 babies born in the United States. The mean weight was 3234 grams with a standard deviation of 871 grams. Assume that birth weight data are approximately bell-shaped. Estimate the number of newborns who weighed between 1492 grams and 4976 grams. Write only a number as your answer. Round your answer to the nearest whole number.
Answer:
1899
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 3234
Standard deviation = 871
Percentage of newborns who weighed between 1492 grams and 4976 grams:
1492 = 3234 - 2*871
So 1492 is two standard deviations below the mean.
4976 = 3234 + 2*871
So 4976 is two standard deviations above the mean.
By the Empirical Rule, 95% of newborns weighed between 1492 grams and 4976 grams.
Out of 1999:
0.95*1999 = 1899
So the answer is 1899

The length of the hypotenuse is 12.52 yards.
Given that a right triangle, we need to find the value of the hypotenuse x,
Trigonometric ratios can be calculated by taking the ratio of any two sides of the right-angled triangle.
We can evaluate the third side using the Pythagoras theorem, given the measure of the other two sides. We can use the abbreviated form of trigonometric ratios to compare the length of any two sides with the angle in the base.
Let us consider a right-angled triangle with one of its acute angles to be x. Then the cosine formula is, cos x = (adjacent side) / (hypotenuse), where "adjacent side" is the side adjacent to the angle x, and "hypotenuse" is the longest side (the side opposite to the right angle) of the triangle.
We know that, the cosine of the angle is the ratio of the base to the hypotenuse,
So,
Cos 37° = 10 / x
x = 10 / Cos 37°
x = 12.52
Hence the length of the hypotenuse is 12.52 yards.
