By performing subtraction we know that the farmer sold 4.2 kilograms of apples in the market.
What is subtraction?One of the four operations used in mathematics, along with addition, multiplication, and division, is subtraction.
Removal of items from a collection is represented by the operation of subtraction.
For instance, in the following image, there are 5 2 peaches, which means that 5 peaches have had 2 removed, leaving a total of 3 peaches.
Subtraction in mathematics is the process of subtracting one integer from another. In other words, the result of subtracting two from five is three. After addition, subtraction is usually the second operation you learn in math class.
So, to find the weight of apples, perform subtraction as follows:
= 6.7 - 2.5
= 4.2 kilograms
Therefore, by performing subtraction we know that the farmer sold 4.2 kilograms of apples in the market.

Given that a : b=11:32 and that b : c=8:9, find the ratio a : b : cGive your ratio in its simplest form with integer parts.
The ratio a : b : c in its simplest form with integer parts is therefore 11 : 32 : 36.
We are informed that
a : b = 11 : 32 ...(1)
b : c = 8 : 9 ...(2)
We must first determine the ratio between a, b, and c in terms of a common component in order to determine the ratio a: b: c. We may accomplish this by using the variable k and writing:
From equation (1), b = 32k
c = (9/8)
(According to equation (2))
The result of putting the first equation into the second equation is:
c = (9/8)(32k)\s= 36k
Hence, we have:
A = B + C = 32k + 36k
We can enter b = 32k into equation (1) to get:
a : (32k) : 36k = 11 : 32
When we multiply both sides by 32, we obtain:
32a : 32(32k) : 32(36k) = 11(32)
Simplifying:
32a : 1024k : 1152k = 352
When we multiply both sides by 32, we get:
a : 32k : 36k = 11 : 32 : 36
Hence, 11: 32: 36 is the ratio of a: b: c in its simplest form with integer parts.

Selina is remodeling her home. She installed a low-flow toilet in her home that flushes 0.8 gallon each time. She replaced her showerhead with a low-flow showerhead that releases 1.5 gal/min. She flushes 12 times a day and showers for 10 minutes a day. On average, her appliances use 40.2 gal/day. Assuming no other appliance use, how much less water will she use than the average U.S. citizen?
The average U.S. citizen uses approximately 88 gallons of water a day.
What is Frequency?
Frequency is a measure of how often an event occurs within a given period of time. It is typically expressed as the number of occurrences of a given event per unit of time. Frequency can be used to measure a variety of phenomena such as the frequency of sound in a given environment or the frequency of a particular chemical element in a given sample.
Selina's low-flow toilet and showerhead will reduce her total water use to just 48.4 gallons per day, a savings of 39.6 gallons of water each day. This is a 44.8% reduction in her water consumption, saving her almost 40 gallons of water per day.
By making these improvements, Selina is helping to conserve a precious resource and limit her environmental impact. Not only is she helping to conserve water, but she is also saving money on her water bill. It is estimated that a typical household can expect to save about $170 annually by making these simple changes.
In addition to her low-flow fixtures, Selina can take additional steps to reduce her water consumption. She can install a water-efficient dishwasher, reduce the frequency of her laundry loads, and install a rain barrel to collect rainwater for gardening. By making these changes, she can reduce her water consumption even further and save even more money.

The shape of the distribution of the time to get an oil change is 15 minute oil change factory is unknown. However records indicate that the mean time is 16.9 and the standard deviation is 4.7 minutes Suppose the manager agrees to pay each employee a $50 bonus if they meet a certain goal. On a typical
Saturday, the oil-change facility will perform 40 oil changes between 10 A.M. and 12 P.M. Treating this as a random
sample, at what mean oil-change time would there be a 10% chance of being at or below? This will be the goal
established by the manager.
There would be a 10% chance of being at or below minutes.
(Round to one decimal place as needed.)
The mean oil-change time for which there is a 10% chance of being at or below is approximately 15.92 minutes.
What is the mean oil-change time?We can start by using the Central Limit Theorem.
Data given:
The population mean is μ = 16.9 minutes
population standard deviation is σ = 4.7 minutes
sample size of n = 40 oil changes performed between 10 A.M. and 12 P.M.
The standard error of the mean (SE) is given by:
SE = σ / √n
SE = 4.7 / √40
SE = 0.743
To find the mean oil-change time for which there is a 10% chance of being at or below, we need to find the z-score associated with the 10th percentile of the standard normal distribution, which is -1.28 (using a standard normal distribution table or calculator).
We can use the formula for a z-score:
z = (x - μ) / SE
where x is the desired mean oil-change time.
Substituting the known values and solving for x, we get:
-1.28 = (x - 16.9) / 0.743
x = -1.28 * 0.743 + 16.9
x = 15.92

Answer:
the future value or total amount due at the end of 8 months is $9,330.00
Step-by-step explanation:
To find the future value of a loan that is borrowed at a simple interest rate, we use the formula:
A = P(1 + rt)
where A is the future value or total amount due, P is the principal or initial amount borrowed, r is the simple interest rate as a decimal, and t is the time period in years.
In this case, the principal is $9000, the simple interest rate is 5.5% or 0.055 as a decimal, and the time period is 8 months or 8/12 = 2/3 years.
Substituting these values into the formula, we get:
A = 9000(1 + 0.055 × 2/3)
= 9000(1.0375)
= $9,330.00
Therefore, the future value or total amount due at the end of 8 months is $9,330.00
we know that a year has 12 months, so 8 months is really 8/12 of a year.

Kathleen begins working and at age 32she invests $6000.0 into a retirement account that pays an APR of 6.4% compounded monthly. She expects to retire at age 65. What will be the size of Kathleen’s total interest when she retires?
By answering the above question, we may state that Hence, when interest Kathleen retires, her total interest will be $10,389.
what is interest ?Divide the principal by the interest rate, the length of time, and other factors to arrive at simple interest. Simple return = principal + interest + hours is the marketing formula. This method makes it easiest to compute interest. The most typical technique to figure out interest is as a portion of the principle sum. He will only pay his share of the 100% interest, for example, if he borrows $100 from a buddy and promises to pay it back with 5% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you give it out, you must charge interest. Interest is often determined as an annual percentage of the loan total. The interest on the loan is this percentage.
[tex]FV = PV x (r/n + 1)(n*t)[/tex]
where: $6,000 is the initial investment's present value, or PV.
6.4% is the yearly interest rate at zero.
n = 12 is the number of times interest is compounded annually (monthly)
33 years are equal to t. (from age 32 to age 65)
When we enter the values, we obtain:
FV = $6,000 x (1 + 0.064/12)(12*33) FV = $6,000 x (1 + 0.00533)396 FV = $6,000 x 2.7315 FV = $16,389 FV = $6,000 x 2.7315 FV = $16,389.0
As a result, Kathleen's retirement account will be worth $16,389.0 when she turns 65.
The difference between the future value and the initial investment is the total interest that Kathleen will earn:
Total interest is equal to $16,389 minus $6,000

Lynette bought a new car for $34,000 . She paid a 20% down payment and financed the remaining balance for 60 months with an APR of 4.4% . Assuming she made monthly payments, determine the total cost of Lynette's car. Round your answer to the nearest cent, if necessary. Formulas
Answer:
The down payment Lynette made is:
Down payment = 20% of $34,000 = $6,800
The amount financed is:
Amount financed = Total price - Down payment
Amount financed = $34,000 - $6,800 = $27,200
To calculate the monthly payment, we can use the following formula:
Monthly payment = (Pr(1+r)^n) / ((1+r)^n - 1)
where:
P = amount financed
r = monthly interest rate
n = number of months
First, we need to calculate the monthly interest rate:
Monthly interest rate = APR / 12
Monthly interest rate = 4.4% / 12 = 0.0036667
Now, we can calculate the monthly payment:
Monthly payment = ($27,200 * 0.0036667 * (1+0.0036667)^60) / ((1+0.0036667)^60 - 1)
Monthly payment = $501.47
The total cost of the car is the sum of the down payment and the total of all the monthly payments over 60 months:
Total cost = Down payment + Monthly payment * 60
Total cost = $6,800 + $501.47 * 60
Total cost = $37,688.20
Therefore, the total cost of Lynette's car is $37,688.20.

What is the spread of 2 1 4 3 5 1 1 2 using standard deviation
The spread of the numbers 2, 1, 4, 3, 5, 1, 1, 2 using standard deviation is approximately 1.768.
We must first determine the mean (average) of the numbers in order to use the standard deviation to determine the spread (i.e., variability) of the set of data.
By adding up all the numbers and dividing by the total number of numbers, the mean is calculated:
mean = (2 + 1 + 4 + 3 + 5 + 1 + 1 + 2) / 8
= 19 / 8
≈ 2.375
The difference between each number and the mean is then determined:
2 - 2.375 = -0.375
1 - 2.375 = -1.375
4 - 2.375 = 1.625
3 - 2.375 = 0.625
5 - 2.375 = 2.625
1 - 2.375 = -1.375
1 - 2.375 = -1.375\s2 - 2.375 = -0.375
Then, each of these discrepancies is squared:
(-0.375)^2 = 0.140625
(-1.375)^2 = 1.890625
(1.625)^2 = 2.640625
(0.625)^2 = 0.390625
(2.625)^2 = 6.890625
(-1.375)^2 = 1.890625
(-1.375)^2 = 1.890625
(-0.375)^2 = 0.140625
The variance is then calculated as the average of these squared differences:
variance is equal to 3.125 x (0.0140625 x 1.890625 x 2.640625 x 0.390625 x 6.890625 x 1.890625 x 0.140625).
Lastly, we calculate the standard deviation by taking the square root of the variance:
(3.125) 1.768 is the standard deviation.
As a result, using standard deviation, the range of the digits 2, 1, 4, 3, 5, 1, 1, 2 is almost 1.768.

If P, then Q.
Not P.
Therefore, not Q.
This is the form of denying the antecedent, where the argument asserts that if P is true, then Q must also be true. However, the argument then proceeds to deny the antecedent by claiming that P is not true, and therefore, Q must not be true either.

An adult pass at the amusement park costs 1.6 times as much as a child’s pass.
How many dollars does an adult pass cost if a child’s pass costs:
By answering the supplied question, we may infer that the response is equation 1.6 x 30 Equals $48 for an adult pass if the price is $30.
so on.
What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
Let's assume that a child's pass costs $x.
The issue states that the price of an adult pass is 1.6 times that of a kid pass. Thus, an adult pass costs:
$1.6 times
So, if a child's pass is expensive:
a) If an adult pass costs $10, then 1.6 x 10 equals $16.
b) $20, then 1.6 x 20 Equals $32 for an adult pass.
1.6 x 30 Equals $48 for an adult pass if the price is $30.
so on.

the the percent change from 50 to 22
Answer:
227.27%
Step-by-step explanation:
Use the graph to answer the question. Graph of polygon ABCD with vertices at 1 comma negative 1, 3 comma negative 5, 7 comma negative 5, 5 comma negative 1. A second polygon A prime B prime C prime D prime with vertices at 1 comma negative 6, 3 comma negative 10, 7 comma negative 10, 5 comma negative 6. Determine the translation used to create the image. 5 units down 5 units up 1 unit down 1 unit up
The image was created by translating 5 units down, 5 units up, 1 unit down, and 1 unit up. ABCD and A'B'C'D' are two polygons on the graph.
The first polygon, ABCD, has vertices at (1,-1), (3,-5), (7,-5), and (8,-5). (5,-1). The vertices of the second polygon, A'B'C'D', are located at (1,-6), (3,-10), (7,-10), and (8,-10). (5,-6).
What exactly are vertices?Vertices are points in a geometric figure that define its shape. A vertex is defined mathematically as the intersection of two or more lines, edges, or curves.
We can compare the coordinates of the two polygons to determine the translation that was used to create the image. The first coordinate of the two polygons is (1,-1) and the second coordinate is (1,-1). (1,-6). The y-coordinate difference is 5 units, so the translation is 5 units down. The two polygons' second coordinate is (3,-5) and (3,-10). The y-coordinate difference is 5 units, so the translation is 5 units down.
The second polygon's third coordinate is (7,-5) and (7,-10). The y-coordinate difference is 5 units, so the translation is 5 units down. (5,-1) is the fourth coordinate of both polygons (5,-6). The y-coordinate difference is 5 units, so the translation is 5 units down.
The image was translated 5 units down, 5 units up, 1 unit down, and 1 unit up.

Suppose you play a game where you roll a fair six-sided die. If the die lands on an even number, you win $2, and if the die lands on an odd number, you lose $1. What is your expected value for one round of this game?
Show Work and Submit Full Answer
Answer:
1 buck
Step-by-step explanation:
Alright man im not a pro at this, so im not gonna have a professional explanation, but the final answer will be correct.
So listen up a dice has 6 sides labeled 1,2,3,4,5,6
3 of those are even
3 of those are odd
so you have a 50% chance of landing on an evan numbered side
and a 50% chance of landing on an odd-numbered side
So basically, if we play one round, there are 2 possibilities. We get even and win 2 bucks, or we get odd and lose a buck. We dont need to worry about probability as they are both 50%. Therfore, the value is 2-1 = 1 dollar. I found the value by subtracting the possbilities.
Find the percent decrease from 498 to 0
As a consequence, the percentage decline from 498 to 0 is equal to 100% of the original value.
what is percentage ?As a fraction of 100, a figure can be expressed as a percentage. For instance, the decimal equivalent of 50% is 50/100 or 0.5. The comparison or representation of changes between two numbers is frequently done using percentages. For instance, a percentage increase or decline indicates how much something has changed from its starting point. Additionally, percentages are frequently used in daily contexts like interest rates, shopping discounts, and academic performance.
given
The formula below can be used to determine the percent reduction from 498 to 0:
(Original value - New value) / 100% of the original value equals the percent decline.
The initial number in this case was 498, and the updated value is 0.
Reduced percentage equals (498 - 0) / (498 x 100%)
% drop equals 100%
As a consequence, the percentage decline from 498 to 0 is equal to 100% of the original value.

How to solve (x-4)^2-9=0
Answer:
Step-by-step explanation:
(x-4)^2-9=0
Let's assume a=x-4 and b=3
We know that,
[tex]a^{2} -b^{2} =(a+b)(a-b)[/tex]
substituting values a, and b in above equation we get,
(x-4+3)(x-4-3)==
(x-1)(x-7)=0
x=1,7
Answer:
[tex]\displaystyle{x=7,1}[/tex]
Step-by-step explanation:
Given the equation:
[tex]\displaystyle{\left(x-4\right)^2-9=0}[/tex]
Add 9 both sides:
[tex]\displaystyle{\left(x-4\right)^2-9+9=0+9}\\\\\displaystyle{\left(x-4\right)^2=9}[/tex]
Square root both sides:
[tex]\displaystyle{\sqrt{\left(x-4\right)^2}=\sqrt{9}}[/tex]
Cancel square root for left side and add plus-minus to right side:
[tex]\displaystyle{x-4=\pm \sqrt{9}}[/tex]
Evaluate the surd of 9:
[tex]\displaystyle{x-4=\pm 3}[/tex]
Add 4 both sides:
[tex]\displaystyle{x-4+4=\pm 3 +4}\\\\\displaystyle{x=\pm 3 +4}[/tex]
Two solutions can be either:
[tex]\displaystyle{x=3+4}[/tex] or [tex]\displaystyle{x = -3+4}[/tex]
