Based on the calculations, the IQR of this data is equal to 2.
How to determine the IQR of this data?
IQR is an acronym for interquartile range and it is a measure of the middle 50% of data values when they are ordered from lowest to highest.
Next, we would order the data from lowest to highest and then determine the median as follows:
Data = {1, 4, 4,} 4, {4, 6, 5}
Median = 4.
For Q₁ of the lower half of the data, we have:
Lower half = {1, 4, 4,}
Q₁ = 4.
For Q₃ of the upper half of the data, we have:
Upper half = {4, 6, 5}
Q₃ = 6.
Mathematically, IQR is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):
IQR = Q₃ - Q₁
IQR = 6 - 4
IQR = 2.

The results of those seven rolls that are shown shows that the range is 5.
What is range?The range is the size of the smallest interval which contains all the data and provides an indication of statistical dispersion. It is measured in the same units as the data.
Given that a six-sided die is rolled 7 times, to give 1, 4, 4, 4, 4, 6, 5, we need to find the range,
The numbers that are gotten include:
1, 4, 4, 4, 4, 6, 5.
It should be noted that range is calculated as:
R = Highest value - Lowest value
R = 6 - 1
R= 5
Therefore, the range from the numbers given is 5.

Palmer participated in sports for eight hours and drama for five hours during a period of two weeks if Palmer continues practicing in these activities at this rate how many hours will he’s been practicing in them during 52 weeks
He has been practicing in sports and drama for 208hours and 130 hours respectively in 52 weeks using unitary method.
What is Unitary method?It is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given Data
We can solve this by unitary method.
Time spent on sports in 2 weeks= 8 hours
Time spent on sports in 1 week= 4 hours
Time spent on sports in 52 weeks = 4×52 hours
That is Palmer has spent 208 hours practicing in sports for 52 weeks.
Similarly, we can calculate for his participation in drama.
Time spent in drama for 2 weeks= 5 hours
Time spent in drama for 1 week= 2.5 hours
Time spent in drama for 52 weeks= 2.5 × 52
That is, Palmer spent 130 hours practicing in drama for 52 weeks.
Collectively, he has been practicing in sports and drama for (208+ 130=)338 hours in 52 weeks using unitary method.

Lines a & m are parallel. Using the diagram below, what is the degree measure of angle 3?
Enter the numerical answer only. Example, if the answer is 12 degrees, only enter 12.
Based on the Alternate Interior Angles Theorem, the degree measure of angle 3 is equal to 153.
What are parallel lines?Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.
What is the Alternate Interior Angles Theorem?The Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent.
Since line a and m are parallel lines, angle 4 and 6 are alternate interior angles. By applying the supplementary angle theorem, the measure of angle 6 is given by:
Q + R = 180°
153° + m<6 = 180°
Angle 6 = 180° - 153°
Angle 6 ≡ Angle 4 = 17°
Now, we can determine the degree measure of angle 3 by applying the supplementary angle theorem:
Q + R = 180°
17° + m<3 = 180°
Angle 3 = 180° - 17°
Angle 3 = 153°

Step-by-step explanation:
357.5 divided by 5 1/2 equals 357 1/2 divided by 11/2, or 715/2 times 2/11 using reciprocals. Multiply and you get 1430/22 which simplifies down to 65. Therefore you were driving at 65 miles per hour
A sample from a population with μ = 40 and σ = 10 has a mean of M = 44. If the sample mean corresponds to a z = 2.00, then how many scores are in the sample?
The number of scores that are in the sample will be 25.
How to calculate the value?From the information, the sample from a population with μ = 40 and σ = 10 has a mean of M = 44 and tthe sample mean corresponds to a z = 2.00.
The number of scores that are in the sample will be:
z = 4 / (10 / ✓n)

Additional comment
The square of a real number is always positive. That should be your first clue that (-4)² = 16 ≠ -16.
Sometimes it helps to remember that an exponent signifies repeated multiplication:
(-4)² = (-4)(-4) . . . . . . has an even number of minus signs, so is positive.
Please note that this is different from -4² = -(4²) = -16.

The length of RS is 58 when S is the midpoint of RT.
Distance is measured in length. According to the International System of Quantities, length has the dimension of distance. In most measurement systems, length is represented by a base unit from which all other units are derived. The International System of Units' fundamental unit of length is the meter.
In geometry, a line segment's midpoint is referred to as the midpoint. It serves as both the segment's and the ends' centroid, and it is equally spaced from both. It cuts the section in half.
If S is the midpoint of the line segment RT then , from the definition we can say that RS = ST
Now we can put the values and solve the equation to find the length of RS .
7x - 5 = 6x + 4
or, x = 9
Therefore RS = 7x - 5 = 7 × 9 - 5 = 58
Hence the length of RS is 58 units.

A car bought for 36000 euro depreciates in value by 8% each year
we have to find the formula for the value of the car V ,after t years
The Car Depreciation Calculator uses the following formulae
:V = P * (1 - R/100)^n
Where,
V is the value of the car after n years,
P is the purchase amount,
R is the percentage rate of depreciation per annum,
n is the number of years after the purchase.
P = 36000,
R =8%,
n = t
The value of the car after n years, V = P * (1 - R/100)^n
= 36000 * (1 - 8/100)^t
= 36000 * (1 - 0.08)^t
= 36000 * (0.92)^t
= 36000 * 0.92^t

The segment is the ends of a line segment are two. These endpoints are included, along with every point on the line that connects them. A segment's length can be measured, while a line's length cannot.
If there are 2 points on a line = 1 line segment; 3 points on a line = 3 segments.

Janet just graduated from college, has a job she's scheduled to begin in 3 months and has decided to treat herself to 6 weeks of travel across South America before she buckles down and starts working full-time. To do the trip, she's thinking of applying for a personal loan of $3500, and the bank she uses for her checking and savings account has offered her an interest rate of 24%. She has a goal of paying off the trip within two years. PLEASE HELP ASAP!!
3) By the time Janet pays off the loan, the total interest she would have paid is D. $941.17.
4) By the time Jane pays off the loan, the total cost of her tip is B. $4,441.17.
5) The equation to find the new balance after each month's payment is D. New balance = Previous balance - Total monthly payment.
How is the monthly payment computed?The monthly payments can be computed by first computing the total payments (future value of the loan). Then, the above figure is divided by the number of periods.
For instance, the total cost of Janet's trip is $4,441.17. The payments are made for 24 months. Dividing $4,441.17 by 24 gives $941.17.
Data and Calculations:N (# of periods) = 24 months (2 x 12)
I/Y (Interest per year) = 24%
PV (Present Value) = $3,500
FV (Future Value) = $0
Results:
PMT = $185.05
Sum of all periodic payments = $4,441.17 ($3,500 + $941.17)
Total Interest = $941.17
Thus, Janet would have spent $4,441.17 to obtain a loan of $3,500 for her trip at 24% interest with 24 months for repayment.

The rectangle will have a 548.1 square foot size and a 94.2-foot periphery.
What are the rectangle's area and perimeter?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be
Area of the rectangle = L×W square units
The length is 21 feet and the width is 26.1 feet.
The perimeter of the rectangle will be
P = 2 (21 + 26.1)
P = 2 x 47.1
P = 94.2 feet
The area of the rectangle will be
A = 21 x 26.1
A = 548.1 square feet
