Dustin walk at the rate of 6 miles per hour.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Dustin can run 2 miles per hour faster than he can walk around the track. If Dustin walks around the track in 20 minutes and runs around the track in 15 minutes.
Let the speed of Dustin walking = x
We know that;
Speed = Distance / Time
For walking;
Speed = Distance / Time
x = Distance / (20/60)
x × 20/60 = Distance
Distance = x/3 miles
For run;
Speed = Distance / Time
⇒ x + 2 = (x/3) / (15/60)
⇒ 3 (x + 2) = 4x
⇒ 3x + 6 = 4x
⇒ 4x - 3x = 6
⇒ x = 6
Thus, Dustin walk at the rate of 6 miles per hour.

Miko packed 40 bottles of perfume in a box. She sold each bottle of perfume for $30. How much money did she receive from sale of 15 boxes of perfume in all?
Answer: $18 000
Step-by-step explanation:
40 bottles per box
40*15 = 600 bottles total
600 * $30 = $18 000
She made $18 000 in total.
Amount of money she receives from sale of 15 boxes of perfume in all is $18,000.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Given that,
Number of bottles of perfume packed in a box = 40
Cost for each perfume = $30
Cost for 40 perfumes = 40 × $30 = $1200
So cost for a box of perfume = $1200
Cost for 15 boxes of perfume = 15 × $1200
= $18,000
Hence the amount for 15 boxes of perfume is $18,000.

Edudig Digger
£35950
Samir buys this digger and expects to use it for 1250 hours each year.
The digger will decrease in value at a yearly rate of 18% of its value at the end of the previous
year.
Use this information to calculate the decrease in value of Samir's digger when it has been
used for 10000 hours.
Answer: To calculate the decrease in value of Samir's digger after 10000 hours, we need to determine its value at the end of each year, taking into account the yearly depreciation of 18%.
Here's the calculation for the first year:
Value at the end of Year 1 = £35950 - (£35950 * 18%) = £29576
And for the second year:
Value at the end of Year 2 = £29576 - (£29576 * 18%) = £24480.48
And so on, until we reach 10000 hours. To determine the exact value after 10000 hours, we would need to perform the calculation for each year until we reach the total number of hours used. However, this calculation would involve multiple steps and can become quite complex. A simpler way to estimate the decrease in value would be to use the concept of present value.

As a result, the actual interest rate is 5.06% since Nolan purchases a $12,000 13-week treasury bill at 5%.
what is interest ?Divide the original by the lending rates, the duration of time, and other factors to arrive at simple interest. Simple gain = principal + interested + hours is the marketing formula. This system makes it simpler to calculate interest. The most popular technique to figure out this is as a portion of the principal sum. He can only pay his share of the 100% interest, for example, if he borrow $100 from a friend he agrees to repay him with 5% interest. $100 (0.05) = $5. When you borrow more money, you should pay interest, and when you give it out, you must make payments. Interest is often determined as an indicator of the overall of the loan total. The interest on the loan is this percentage.
given
Simple interest = $12,000 × 0.05 × 13/52 = $150
Simple discount note = ($12,000 - $150) × 13/52 = $2962.5

I=PRT
P=5,600
R=0.2
T=4
Step-by-step explanation:
The formula "I=PRT" is the simple interest formula, where:
I = interest
P = principle (the initial amount of money)
R = interest rate (as a decimal)
T = time (in years)
Given the values of P, R, and T:
P = 5,600
R = 0.2
T = 4
We can plug these values into the formula to find the interest:
I = P * R * T = 5,600 * 0.2 * 4 = 4,480
So, the interest earned on a principle of $5,600 at an interest rate of 0.2 (or 20%) for 4 years would be $4,480.

_______ is the error due to the particular sample selected being an imperfect representation of the population of interest. it may be defined as the variation between the true mean value for the sample and the true mean value of the population.
Random sampling error is the error due to the particular sample selected being an imperfect representation of the population of interest.
What is random sampling error?When an analyst selects a sample that is not a true representation of the entire population of data, they commit a statistical error known as a sampling error. The results of the sample therefore do not fairly represent the results of the entire population.
Sampling is a type of analysis where a small sample of observations are selected from a larger population. The selection process has the potential to result in both sampling errors and non-sampling errors.
According to the definition, random sampling error is the error that results from the particular sample being chosen not accurately representing the population of interest. It could be described as the difference between the true mean value for the sample and the true mean value of the population.

A sugar solution was made by mixing 11qt. of a 70% sugar solution and 4 qt. of a 85% sugar solution. Find the concentration of the new mixture.
Answer:
Step-by-step explanation:
To find the concentration of the new mixture, we need to find the total amount of sugar in the mixture, and then divide it by the total volume of the mixture.
Let's first find the amount of sugar in each of the two original solutions:
70% solution: 11 qt. * 70% = 7.7 qt. of sugar
85% solution: 4 qt. * 85% = 3.4 qt. of sugar
Now we add the volume of the two original solutions to find the total volume of the new mixture:
Total volume: 11 qt. + 4 qt. = 15 qt.
And add the amount of sugar in the two original solutions to find the total amount of sugar in the new mixture:
Total sugar: 7.7 qt. + 3.4 qt. = 11.1 qt.
Finally, we divide the total amount of sugar by the total volume to find the concentration of the new mixture:
Concentration: 11.1 qt. / 15 qt. = 0.7407 (rounded to four decimal places).
So the new mixture is approximately 74.07% sugar.

Use the vertex ( h, k ) and a point on the graph ( x, y ) to find the standard form of the equation of the quadratic function:
Vertex = (0,6)
Point = (2,7)
G( x )= Answer field 1
(x- Answer field 2
)^2 +Answer field 3
The required equation of the quadratic function in standard form is:
f(x) = (1/4) x² + 6.
A parabola is a cross-section cut out of the cone and represented by an equation f(x) = a(x - h)² + k.
The standard form of a quadratic function is given by:
f(x) = a(x - h)² + k
where (h, k) is the vertex of the parabola.
Given the vertex (0, 6) and the point (2, 7), we can find the values of a and k and use them to write the equation in standard form.
Let's use the vertex form of the equation:
f(x) = a(x - h)² + k
Since the vertex is (0, 6), we have h = 0 and k = 6:
f(x) = a(x - 0)² + 6
f(x) = a × x² + 6
Next, we use the point (2, 7) to find the value of a:
f(2) = a × 2² + 6
7 = 4a + 6
7 - 6 = 4a
1 = 4a
a = 1/4
So, the equation of the quadratic function in standard form is:
f(x) = (1/4) x² + 6

The average score for the class on the exam was 78 points with a standard deviation of 6.4 points. The student who took the make-up exam scored 79.25points.
1. Calculate the mean of the first 23 exams:
Mean = 78 points
2. Calculate the standard deviation of the first 23 exams:
Standard Deviation = 6.4 points
3. Calculate the mean of the entire class:
Mean = (78 x 23) + 62 = 1840 + 62 = 1902
Total = 24
Mean = 1902 / 24 = 79.25 points
The average exam score for the class of 24 students was 78 points with a standard deviation of 6.4 points. This means that most students in the class scored between 71.6 and 84.4 points on the exam. The student who took the make-up exam the following day scored 79.25points. This score is significantly lower than the average score of the class, suggesting that the student may have not done as well on the exam compared to the other students. It is also possible that the student faced additional challenges that the other students did not have to face, such as taking the exam on a different day.

Add 3 and 4 to get 7
then divide 245 by 7 to get 35.
after you will need to times 35 by the ratio of boys which is 3.
35 ×3 =105.
So your answers is 105 boys.
Answer: 105 preschoolers are boys
The first thing we must do is add up our total to get a starting fraction. 3+4 is 7. Which means 3/7 of our students are boy and 4/7 of our students are girls.
Next we must multiply our total students "245" into the number of boys and girls.
3/7 x 245 is 105. 4/7 x 245 is 140.
105+140 is 245, which means our numbers are correct.
And finally that leads us with our answer.
105 of the students are boys.
