A farmer sells 6.7 kilograms of pears and apples at the farmer's market. 2 5 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
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.

Suppose you have 3 jars with the following contents. Jar 1 has 1 white ball and 1 black ball. Jar 2 has 2 white balls and 1 black ball. Jar 3 has 1 white ball and 1 black ball. One jar is to be selected, and then 1 ball is to be drawn from the selected jar. The probabilities of selecting the first, second, and third jars are 1/2, 1/3, and 1/6 respectively. Find the probability the ball was drawn from Jar 3, given that the ball is white.
Given that the ball is white, the probability that it was taken from Jar 3 is 1/5, or 0.2. Given that the ball is white, there is a 20% likelihood that it was selected from Jar 3.
How is probability determined?We must apply Bayes' theorem in order to determine the likelihood that the ball was taken from Jar 3 given that it is white. Let J stand for the scenario in which Jar 3 is chosen, and W for the scenario in which a white ball is drawn. Next, we have:
P(W | J) * P(J) / P = P(J | W) (W)
where P(J) is the prior probability of choosing Jar 3 (1/6), P(W) is the probability of drawing a white ball, and P(W | J) is the probability of drawing a white ball provided that Jar 3 is chosen.
We must apply the law of total probability to determine P(W):
P(W) is equal to P(W | J1) * P(J1), P(W | J2) * P(J2), and P(W | J3) * P. (J3)
where P(W | J1) represents the likelihood that a white ball will be drawn if Jar 1 is chosen (which is 1/2), P(W | J2) represents the likelihood that a white ball will be drawn if Jar 2 is chosen (which is 2/3), and P(W | J3) represents the likelihood that a white ball will be drawn if Jar 3 is chosen (which is 1/2).
Now that the values have been inputted, we can calculate:
P(W) = (1/2 * 1/2) + (2/3 * 1/3) + (1/2 * 1/6) = 5/12
P(J | W) = (1/2 * 1/6) / (5/12) = 1/5

A meteorologist reports that the chance of snow is less than 30%. The correct inequality to represent this comparison is s < 30. The variable s represents the likelihood of snow.
Which numbers are solutions of the inequality?
Choose all that apply.
20%
35%
17%
30%
29 and one-half percent%
1.5%
The solutions to the inequality s < 30 are 20%, 17%, 29 and one-half percent (which is equivalent to 29.5%), and 1.5%.
The disparity that best illustrates the phrase "the possibility of snow is less than 30%" is:
s < 30
This implies that the inequality can be solved for any value of s that is less than 30.
We must compare the numbers to 30 and see if they are less than it in order to identify which ones are the answers to the inequality.
The answer is yes because 20% = 0.2 is less than 30%.
It is not a solution because 35% = 0.35 is not less than 30%.
The answer is yes because 17% = 0.17 is less than 30%.
It is not a solution because 30% = 0.3 is not less than 30%.
That is a solution since 29 and a half percent = 0.295 is less than 30%.
The answer is yes because 1.5% = 0.015 is less than 30%.
As a result, the answers to the inequality s 30 are 20%, 17%, 29 and a half percent (or 29.5%), and 1.5 percent.

O is the center of the regular octagon below. Find its area. Round to the nearest tenth if necessary.
The answer of the given question based on regular octagon ,the area of the regular octagon with center O is approximately 232.98 square units.
What is Area?Area is measure of amount of space inside 2-dimensional figure or shape, usually measured in square units like square centimeters or square meters. It is calculated by multiplying length and width of the figure or a shape.
To find the area of a regular octagon, we need to use the following formula:
A = 2(1 + √2) × s²
Since O is the center of the octagon, we can draw lines from O to each vertex of the octagon. This will divide the octagon into 8 congruent isosceles triangles.
Let's call the length of each side of the octagon "s". Then the base of each triangle will also be "s". We can use the Pythagorean theorem to find the length of the other sides of the triangle:
s²+ s² = (2s)²/2
2s² = 4s² - 4s²/2
2s² = 2s²/2
s² = s²/2
s = √2s/2
Now we can substitute this value of s into the formula for the area of the octagon:
A = 2(1 + √2) × s²
A = 2(1 + √2) × (√2s/2)²
A = 2(1 + √2) × 2s²/4
A = (1 + √2) × s²/2
A = (1 + √2) × (17/2)²/2
A ≈ 232.98 square units
Therefore, the area of the regular octagon with centre O is approximately 232.98 square units.

The diameter of a circle is 10 3/4 inches.
What is the radius, r, of the circle?
Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer: The radius of the circle is 5 3/8 inches.
Step-by-step explanation:
The radius of the circle is half of the diameter. We can start by converting the mixed number diameter to an improper fraction:
10 3/4 = (10 × 4 + 3)/4 = 43/4
So, the diameter of the circle is 43/4 inches. The radius is half of this, which we can find by dividing by 2:
r = (43/4) ÷ 2 = 43/8
To simplify the fraction, we can divide the numerator and denominator by their greatest common factor (GCF), which is 1:
r = 43/8 = 5 3/8
Therefore, the radius of the circle is 5 3/8 inches.
Answer:5 3/4
Step-by-step explanation:

Find the number of arrangements that can be made by taking 4 letters from the letters of the word addressee.
Answer: The word "addressee" has 8 letters. To find the number of arrangements that can be made by taking 4 letters from these 8 letters, we can use the formula for combinations, which is:
n C r = n! / (r! * (n-r)!)
where n is the total number of items, r is the number of items to be selected, and ! represents the factorial function.
In this case, we want to select 4 letters from the 8 letters in "addressee", so n = 8 and r = 4. Substituting these values into the formula, we get:
8 C 4 = 8! / (4! * (8-4)!)
= (8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / [(4 * 3 * 2 * 1) * (4 * 3 * 2 * 1)]
= 70
Therefore, there are 70 different arrangements that can be made by taking 4 letters from the letters of the word "addressee".

a helicopter hovers 1400 feet above a small island. the figure shows that the angle of the depression from the to the point P is 30 degrees. how far off the coast, to the nearest foot, is the island?
Step-by-step explanation:
this (outside) angle of depression is equal to the inner angle at P.
because the line of sight from the helicopter to P is like the diagonal in a rectangle spring the rectangle into 2 equal right-angled triangles (one of just rotated by 180° of the other).
so, the angle at P is 30°.
1400 ft = sin(30)×radius
radius being the line of sight from the helicopter to P.
we need to calculate the radius, because we need it for d :
d = cos(30)×radius
radius = 1400/sin(30) = 2800 ft
d = cos(30)×2800 = 2,424.871131... ft ≈ 2,425 ft

You have a portfolio consisting solely of Stock A and Stock B. The portfolio has an expected return of 10.2 percent. Stock A has an expected return of 11.7 percent while Stock B is expected to return 8.3 percent. What is the portfolio weight of Stock A?
The portfolio weight of Stock A is 0.625 for the given situation.
What use do portfolio weights serve?The percentage of a portfolio's investments that are assigned to each asset or security is shown by the portfolio weights. Investors can meet their chosen risk and return objectives by varying the weights of various assets in their portfolios. Portfolio weights are a key component of asset allocation and portfolio optimization methodologies since they are used to determine the expected return and risk of a portfolio.
Let w be the weight (proportion) of Stock A in the portfolio.
The weight of Stock B would be (1-w).
Given that, the portfolio has an expected return of 10.2 percent.
0.102 = w(0.117) + (1-w)(0.083)
w = (0.102 - 0.083)/(0.117 - 0.083) ≈ 0.625
Hence, the portfolio weight of Stock A is 0.625 for the given situation.

Which of the following sets of numbers could represent the three sides of a right triangle? O {9, 24, 26} O {37, 77,85} O {65, 72, 97} O {32, 56, 65}
From the given data, the only set of numbers that could represent the sides of a right triangle is {9, 24, 26}.
The set of numbers that could represent the three sides of a right triangle is {9, 24, 26}.
To determine if a set of numbers could represent the sides of a right triangle, we can use the Pythagorean theorem, which states that for a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. That is,
c² = a² + b²
where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.
For the set {9, 24, 26}, we have:
26² = 9² + 24²
676 = 81 + 576
Therefore, the set {9, 24, 26} could represent the three sides of a right triangle.
For the other sets:
{37, 77, 85}: 85² ≠ 37² + 77², so this set does not represent the sides of a right triangle.
{65, 72, 97}: 97² ≠ 65² + 72², so this set does not represent the sides of a right triangle.
{32, 56, 65}: 65² ≠ 32² + 56², so this set does not represent the sides of a right triangle.

The monthly cost for an HCF of 24 will be $39.13.
What is an expression?In mathematics, an expression is a combination of symbols and/or numbers that represents a quantity or a mathematical relationship between quantities. An expression can consist of variables, constants, and operators such as addition, subtraction, multiplication, and division.
Since the monthly water bill is a linear function of the amount of water used, we can use the point-slope form of a linear equation to write an equation for the line. Let y be the monthly cost (in dollars) and x be the amount of water used (in HCF). Then the equation of the line is:
y - 49.58 = 1.65(x - 21)
Simplifying this equation, we get:
y = 1.65x - 13.57
This means that the monthly cost (y) is equal to 1.65 times the amount of water used (x) minus a constant term of $13.57.
To find the monthly cost for 24 HCF, we simply substitute x = 24 into the equation we just found:
y = 1.65(24) - 13.57
y = 39.13
Therefore, the monthly cost for 24 HCF is $39.13.
