The percentage did the total yield, by weight, of her fruit harvest declined by approximately 24%, which is option B.

what is percentage ?

Percentage is a way of expressing a number or quantity as a fraction of 100. It is often denoted by the symbol % (percent). For example, 50% means 50 out of 100, or 50/100, or the equivalent fraction 1/2.
Percentages are commonly used in many real-world situations, such as in finance, statistics, and everyday life. They are often used to express changes, differences, or ratios between two values.

According to the question:

To solve this problem, we need to calculate the total weight of fruit harvested in the first year and the total weight of fruit harvested in the second year, and then calculate the percentage decline.

Total weight of fruit harvested in the first year = 40 + 12 = 52 pounds

After a 25% decline, the weight of pears in the second year = 40 - 0.25(40) = 30 pounds

After a 20% decline, the weight of plums in the second year = 12 - 0.20(12) = 9.6 pounds

Total weight of fruit harvested in the second year = 30 + 9.6 = 39.6 pounds

Percentage decline in the total yield of fruit harvest = [(52 - 39.6)/52] x 100% = 23.8%

Therefore, the answer is approximately 24%, which is option B.

Answer:

The scale of measurement used by the researcher is interval scale as the data is continuous and there are equal intervals between the values.

Mean = (1+2+4+5+7+11)/6 = 5

Median = (4+5)/2 = 4.5

Mode = There is no mode in the data set as none of the numbers are repeated.

Range = maximum value - minimum value = 11 - 1 = 10

Sample Variance = ((1-5)^2 + (2-5)^2 + (4-5)^2 + (5-5)^2 + (7-5)^2 + (11-5)^2)/(6-1) = 14.67

Standard Deviation = sqrt(sample variance) = sqrt(14.67) = 3.83

Mean + 2SD = 5 + 2*3.83 = 12.66, rounded to the nearest integer = 13.

According to the Empirical Rule, 68% of the sample lies within 1 standard deviation of the mean. Therefore, we need to find the values that are 1 standard deviation away from the mean:

Lower limit = Mean - SD = 5 - 3.83 = 1.17, rounded to the nearest integer = 1.

Upper limit = Mean + SD = 5 + 3.83 = 8.83, rounded to the nearest integer = 9.

So the number of leaves associated with 68% of the sample is between 1 and 9.

Here are the step-by-step instructions to find the number of ear cleanings that the groomer gave:

Start with the given number of nail trims, which is 15.

Divide the number of nail trims by 5 to find out how many groups of 5 nail trims there are. This gives us: 15 ÷ 5 = 3.

Multiply the number of groups of 5 nail trims by the corresponding ratio of ear cleanings per 5 nail trims, which is 3. This gives us: 3 × 3 = 9.

This means that for every 5 nail trims, the groomer gave 3 ear cleanings, and since the groomer gave 15 nail trims, they gave 9 ear cleanings in total.

So, the pet groomer gave 9 ear cleanings in total.

The monthly payments are $248.53.

The total amount that he will pay $14911.8.

The amount of interest is $4911.8

What is the interest rate?

The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate. The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.

The formula of monthly payment is

P = [tex]\frac{r (PV)}{1-(1-r)^{-n}}[/tex]

r is the rate of interest.

PV is the present value

n is the number of terms.

The bank offers you an installment loan with an interest rate of 17% over a 60-month term. The cost of the car is $10,000.

PV = $10,000

n = 60

r = 17%/12 = 0.17/12

The monthly installment is

P = [tex]\frac{ \frac{0.17}{12}\times 10000}{1-(1- \frac{0.17}{12})^{-60}}[/tex]

P = 248.53

The monthly installment is $248.53.

Total payment is (60 ×$248.53) = $14911.8

The interest is $(14911.8 - 10000) = $4911.8

By answering the above question, we may state that As a result, $35.40 interest in simple interest is due for the use of the funds.

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.

For simple interest, use the formula:

I = P * r * t

where I represents the amount of interest payable, P the amount borrowed, r the interest rate, and t the length of time in years.

Inputting the values provided yields:

I = $590 * 0.03 * 2

I = $35.40

So the lowest price that yields a revenue of $7840 is $32 and the highest price is $64.

The first ten integers are the basic numbers in mathematics. The range of these vital values is 0 to 9. Basic integers in the 0 to 9 range include 0 through 1, 2, 3, 4, 5, 6, 7 and 8.

The total revenue from selling x units is given by:

R = xp

Substituting the demand equation p = 128 - 0.04x, we get:

R = x(128 - 0.04x)

R = 128x - 0.04x²

To find the prices that yield a revenue of $7840, we can set R equal to 7840 and solve for x:

7840 = 128x - 0.04x²

0.04x² - 128x + 7840 = 0

Dividing both sides by 0.04, we get:

x² - 3200x + 196000 = 0

Using the quadratic formula, we can solve for x:

x = [3200 ± √(3200² - 4(1)(196000))] / 2

x = [3200 ± √(10240000)] / 2

x = [3200 ± 3200] / 2

x = 1600 or x = 2400

Therefore, the corresponding prices that yield a revenue of $7840 are:

p = 128 - 0.04x

p = 128 - 0.04(1600) = 64 dollars

p = 128 - 0.04(2400) = 32 dollars

So the lowest price that yields a revenue of $7840 is $32 and the highest price is $64.

Answer:

Step-by-step explanation:

To start, let's use algebra to set up some equations based on the information we have. We know that Trip has a total of 15 coins and their total value is 95 cents. Let's call the number of nickels Trip has "n" and the number of dimes "d". Then we can write:

n + d = 15 (since Trip has a total of 15 coins)

0.05n + 0.1d = 0.95 (since the total value of the coins is 95 cents)

Next, we know that four of the coins are each worth twice as much as the rest. Let's call the value of the "rest" coins "x". Then the value of the four coins that are worth twice as much is 2x. We can set up an equation based on the total value of the coins using these values:

4(2x) + 11x = 95

Simplifying this equation, we get:

19x = 95

x = 5

Now we know that each of the "rest" coins is worth 5 cents. We can substitute this value into the equation for the total value of the coins to get:

4(2*5) + 11(5) = 95

Simplifying this equation, we get:

40 + 55 = 95

So our values for n and d are correct: Trip has 11 nickels and 4 dimes.

To justify this argument, we can use a proof by contradiction. Suppose that Trip had a different number of nickels or dimes. If Trip had more than 11 nickels, then the total value of the nickels alone would be greater than 55 cents, which is impossible since the total value of all the coins is only 95 cents. Similarly, if Trip had more than 4 dimes, then the total value of the dimes alone would be greater than 40 cents, which is also impossible. Therefore, Trip must have exactly 11 nickels and 4 dimes, and our argument is justified.
