Due to the annual rate of inflation, a gallon of milk that costs $3. 25 today would have cost $1. 75 if it was bought 20 years ago.
Answers
The annual rate of inflation between the two time periods is approximately 3.05%.
To calculate the annual rate of inflation, we can use the formula:
Annual Inflation Rate = ((Current Price - Past Price) / Past Price) * 100 / Number of Years
Plugging in the values, we have:
((3.25 - 1.75) / 1.75) * 100 / 20 ≈ 0.153 * 100 / 20 ≈ 3.05%
Therefore, the annual rate of inflation between the two time periods is approximately 3.05%.
Inflation refers to the general increase in prices over time, which leads to a decrease in the purchasing power of money. In this case, the cost of a gallon of milk has increased from $1.75 to $3.25 over 20 years. By calculating the annual rate of inflation, we find that prices have been rising at an average rate of 3.05% per year during this period.
This means that the cost of goods and services, including milk, has increased by an average of 3.05% each year due to inflation. It highlights the importance of considering inflation when comparing prices and understanding the impact it has on the value of money over time.
In conclusion, based on the given information, the annual rate of inflation between the two time periods is approximately 3.05%, indicating the increase in the cost of a gallon of milk over 20 years.

In a positively skewed distribution, what order (left to right) will we find the mean, median and more
Answers
So the order from left to right would be: Mode, Median, Mean.
In a positively skewed distribution, the mean is typically larger than the median, and the median is larger than the mode.
This can be illustrated in the following way:
Mean: The mean is affected by extreme values in the tail of the distribution, and will be pulled in the direction of the skew. Therefore, in a positively skewed distribution, the mean will be to the right of the median.
Median: The median is the value that separates the lower 50% of the data from the upper 50% of the data. In a positively skewed distribution, the tail of the distribution is on the right-hand side, which means that the median will be closer to the left-hand side than the mean.
Mode: The mode is the most frequent value in the distribution. In a positively skewed distribution, the mode will be the smallest value, located at the left-hand side of the distribution, while the mean and median will be to the right of it.

Answers
Answer:
A
Step-by-step explanation:
The sum of angles in a quadrilateral is 180
\((x - 5) + (x + 35) + 1.4x + x = 360\)
\(2x + 30 + 1.4x + x = 360\)
\(4.4x + 30 = 360\)
\(4.4x = 330\)
\(x = 75\)
\(x = 75\)
\((x - 5) = 70\)
\((x + 35) = 110\)
\(1.4x = 105\)
\(x = 75\)
Answer:
A. 75°, 70°, 110°, 105°, 75°
Step-by-step explanation:
As the figure says, the sum of all the angles is 360 degrees, thus, write down:
\((x-5)+(x+35)+1.4x+x=360\)
And solve for x:
\((x-5)+(x+35)+1.4x+x=360\\4.4x-5+35=360\\4.4x+30=360\\4.4x=330\\x=75\)
Replace x into the other angles and solve:
\(A_1=(75-5)=70\\A_2=(75+35)=110\\A_3=1.4(75)=105\\A_4=75\)
Choice A shows all the correct angle measures, therefore, A is the correct answer.

The triangle inequality states that the sum of the two shortest side lengths must be greater than the largest side length of the triangle. Basically, we need to find if DE + FE > DF. We know that DE = 1/2 DF and FE = 1/3 DF so the inequality becomes 1/2 DF + 1/3 DF > DF which simplifies to 5/6 DF > DF.

dujuan bought a car for $ 17000 , and ever since the car's value has decreased exponentially by 17 % per year. how long will it take for the car's value to be $ 5000 ?
Answers
It will take approximately 8.84 years for the car's value to be $5000.
We can use the formula for exponential decay to find the time it takes for the car's value to reach $5000:
V = V0 * \(e^{(-rt)\)
where V is the current value, V0 is the initial value, r is the decay rate, and t is the time in years. We can rearrange this formula to solve for t:
t = -ln(V/V0) / r
Plugging in the given values, we get:
t = -ln(5000/17000) / (-0.17) = 8.84 years (rounded to two decimal places)

a group of roommates equally shared the 6000$ in rent for an apartment. when four of the roomates moved out, those roomates remaining still shared the 6000$ rent equally, but each roomate's share of the rent increased by 250$. how many roomates were there orginally
Answers
The original number of roommates was 6, determined by comparing the original and new shares of rent per roommate and solving for the minimum number of roommates that satisfies the inequality.
Let's assume that there were 'x' original roommates in the apartment.
When the rent was shared equally among 'x' roommates, each roommate's share was:
\(6000/x\)
After four roommates moved out, the remaining roommates continued to share the same rent of $6000 but each person's share increased by $250. So the new share per roommate is:
\((6000/x) + 250\)
Since the number of roommates decreased by 4, the new number of roommates is:
\(x - 4\)
We know that the new share per roommate is greater than the original share per roommate, so we can set up the following inequality:
\((6000/x) + 250 > 6000/x\)
Simplifying the inequality, we get:
\(250 > 6000/x - 6000/x\)
\(250 > 6000/x^2\)
\(x^2 > 24\)
\(x > 4.9\)
Since the number of roommates must be a whole number, the minimum value for x is 6.
Therefore, there were originally 6 roommates in the apartment.
The solution involves setting up an inequality to compare the original share of the rent per roommate with the new share of the rent per roommate, and then solving for the minimum number of original roommates that satisfies the inequality.

Each day that Barney goes to college, he either goes by bus or he walks.
The probability that Barney will go to college by bus on any day is 0.3
When Barney goes to college by bus, the probability that he will be late is 0.2
When Barney walks to college, the probability that he will be late is 0.1
Barney will go to college on 200 days next year.
Work out an estimate for the number of days Barney will be late for college next year.
Answers
Let's break down the problem step by step:
1. Probability of going by bus: The probability that Barney will go to college by bus on any given day is 0.3. Since he will go to college on 200 days next year, we can estimate that he will go by bus on 0.3 * 200 = 60 days.
2. Probability of being late when going by bus: The probability that Barney will be late when he goes to college by bus is 0.2. Therefore, on the 60 days he goes by bus, we can estimate that he will be late on 0.2 * 60 = 12 days.
3. Probability of walking: Since Barney either goes by bus or walks, the remaining days (200 - 60 = 140) are the days he walks to college.
4. Probability of being late when walking: The probability that Barney will be late when he walks to college is 0.1. Therefore, on the 140 days he walks, we can estimate that he will be late on 0.1 * 140 = 14 days.
Finally, to estimate the total number of days Barney will be late for college next year, we sum the estimated days for each mode of transportation: 12 days (going by bus) + 14 days (walking) = 26 days.
Therefore, an estimate for the number of days Barney will be late for college next year is 26 days.

Answers
Given that April has 30 days, Luke used, on average, 20.05 kilowatt-hours of electricity per day during April.
What is average?The average is the mean value obtained by dividing the total value of a data set by the number of items.
In this situation, we can divide the total electric bill for April by 30 to obtain the average daily charge.
In addition, we can divide the average charge per day by the cost per kilowatt-hour to obtain the number of kilowatt-hours used per day.
The total electric bill for April = $84.21
The charge per kilowatt-hour (kWh) = $0.14
The number of days in April = 30
The bill per day = $2.807 ($84.21/30)
The kilowatt-hours per day = 20.05 kWh ($2.807/$0.14)

Answers
Over the past 10 years, you have paid off $1,80,000 - $1,12,681 = $67,319 of the original loan.
This amount represents the reduction in the loan balance over the years. It is essential to consider that your monthly payments were not entirely directed towards the loan principal; a portion went towards paying interest charges. As a result, the loan balance was gradually reduced over time.
The interest on the loan accumulated each month, which affected the allocation of your payments. Initially, a significant portion of your payments likely went towards interest, with a smaller fraction reducing the principal balance. However, as time progressed, the interest portion decreased, and more of your payments started chipping away at the loan's principal.
It is crucial to recognize the impact of interest on loans, especially over extended periods. The difference between the current value of your house and the remaining loan balance illustrates the progress you have made in building equity over the years. As you continue making payments, the loan balance will further diminish, and your equity will continue to grow.

In ΔGHI, the measure of ∠I=90°, the measure of ∠G=82°, and GH = 3. 4 feet. Find the length of HI to the nearest tenth of a foot
Answers
In triangle ΔGHI, with ∠I measuring 90° and ∠G measuring 82°, and GH measuring 3.4 feet, the length of HI is 24.2 feet.
To find the length of HI, we can use the trigonometric function tangent (tan). In a right triangle, the tangent of an angle is equal to the ratio of the length of the side opposite the angle to the length of the side adjacent to it. In this case, the side opposite ∠G is HI, and the side adjacent to ∠G is GH. Therefore, we can set up the equation: tan(82°) = HI / GH.
Rearranging the equation to solve for HI, we have: HI = GH * tan(82°). Plugging in the given values, we get: HI = 3.4 * tan(82°). Using a calculator, we find that tan(82°) is approximately 7.115. Multiplying 3.4 by 7.115, we find that HI is approximately 24.161 feet. Rounded to the nearest tenth of a foot, the length of HI is 24.2 feet.
