Answer: It's not clear what measures 3.8 and 9.2 represent. However, if they represent angles in degrees, then the range of these measures would be:
- If there are no restrictions on the angles, the range would be [0°, 360°), meaning any angle between 0 degrees and 360 degrees (excluding 360 itself).
- If the angles are restricted to be acute angles (less than 90 degrees), then the range would be (0°, 90°), meaning any angle between 0 degrees and 90 degrees (excluding 0 and 90 themselves).
- If the angles are restricted to be obtuse angles (between 90 and 180 degrees), then the range would be (90°, 180°), meaning any angle between 90 degrees and 180 degrees (excluding 90 and 180 themselves).
- If the angles are restricted to be right angles (exactly 90 degrees), then the range would be {90°}, meaning only the angle of 90 degrees.

Step-by-step explanation:

An integer is 17 more than 4 times another. If the product of the two integers is -15, then find the integers.
Let's use algebra to solve this problem.
Let x be one of the integers, and y be the other integer.
From the problem, we know that:
x = 4y + 17 (one integer is 17 more than 4 times the other)
xy = -15 (the product of the two integers is -15)
We can use substitution to solve for one of the variables. From the first equation, we can write:
y = (x - 17)/4
Substituting this expression for y into the second equation gives:
x(x - 17)/4 = -15
Multiplying both sides by 4 and expanding gives:
x^2 - 17x = -60
Rearranging gives:
x^2 - 17x + 60 = 0
This is a quadratic equation that can be factored as:
(x - 5)(x - 12) = 0
So the solutions are:
x = 5, y = (-12/4) = -3
x = 12, y = (-5/4) = -1.25
Since the problem states that the integers are both integers, the only valid solution is:
x = 5, y = -3
Therefore, the two integers are 5 and -3.

Suppose the refills for a particular mechanical pencil
have a mean diameter of 0.5 mm and standard
deviation of 0.007 mm. Refills below 0.485 mm do not
stay in the pencil, while those above 0.520 mm do not
fit in the pencil at all.
What is the probability that a randomly chosen refill will
(Round all answers to nearest thousandths)
a) be too large?
b) be too small?
c) fit correctly?
回
Answer:
the probability that a randomly chosen refill will fit correctly is 0.9780 (rounded to three decimal places).
Step-by-step explanation:
We can use the standard normal distribution to solve this problem. We first need to calculate the z-scores for the given diameters.
a) To find the probability that a randomly chosen refill will be too large, we need to find the probability of getting a diameter greater than 0.520 mm.
z-score = (0.520 - 0.5) / 0.007 = 2.857
Using a standard normal table or calculator, we find that the probability of getting a z-score of 2.857 or greater is 0.0021.
Therefore, the probability that a randomly chosen refill will be too large is 0.0021 (rounded to three decimal places).
b) To find the probability that a randomly chosen refill will be too small, we need to find the probability of getting a diameter less than 0.485 mm.
z-score = (0.485 - 0.5) / 0.007 = -2.143
Using a standard normal table or calculator, we find that the probability of getting a z-score of -2.143 or less is 0.0164.
Therefore, the probability that a randomly chosen refill will be too small is 0.0164 (rounded to three decimal places).
c) To find the probability that a randomly chosen refill will fit correctly, we need to find the probability of getting a diameter between 0.485 mm and 0.520 mm.
First, we find the z-scores for each diameter:
z-score for 0.485 mm = (0.485 - 0.5) / 0.007 = -2.143
z-score for 0.520 mm = (0.520 - 0.5) / 0.007 = 2.857
Using a standard normal table or calculator, we find that the probability of getting a z-score between -2.143 and 2.857 is 0.9780.
Therefore, the probability that a randomly chosen refill will fit correctly is 0.9780 (rounded to three decimal places).
Suppose I am rolling a standard 6-sided dice. Let A be the event I roll a prime number, Let B be the event I roll a number less than or equal to 4. I ran a trial 10 times and got the results 2, 4, 3, 1, 5, 6, 1, 3, 2, 1
What is the experimental P(B)
The experimental probability of rolling a number less than or equal to 4 is 0.7.
How is conditional probability calculated? What does it mean?The likelihood that an event (A) will occur given the occurrence of another event (B) is known as conditional probability. P(A|B), which stands for "the probability of A given B," is used to express it. You must first determine P(A and B) by multiplying the odds of A and B happening together. Next, you may compute P(A|B). The conditional probability of A given B is then obtained by dividing the result by P(B).
Several situations in everyday life, including medical diagnosis, industrial quality control, and risk assessment in insurance, call for the usage of conditional probability.
Given that, the trial was run 10 times.
Thus,
P(B) = (number of times B occurred) / (total number of trials)
= 7 / 10
= 0.7
Therefore, the experimental probability of rolling a number less than or equal to 4 is 0.7.

Answer:
The simplified expression is -13/12. (are you sure you don't have a typo somewhere), double checked.
Step-by-step explanation:
First, let's simplify the expression inside the absolute value bars:
5/6 - 17/12 = 10/12 - 17/12 = -7/12
Next, we can simplify the expression outside the absolute value bars:
| -7/12 | - | 5/3 |
= 7/12 - 5/3 (since the absolute value of -7/12 is 7/12)
= 7/12 - 20/12
= -13/12
The simplified expression is -13/12.
_______________________
Simplify the following:
abs(5/6 - 17/12) - abs(5/3)
Put 5/6 - 17/12 over the common denominator 12. 5/6 - 17/12 = (2×5)/12 - 17/12:
abs(((2×5)/12 - 17/12)) - abs(5/3)
2×5 = 10:
abs(10/12 - 17/12) - abs(5/3)
10/12 - 17/12 = (10 - 17)/12:
abs(((10 - 17)/12)) - abs(5/3)
10 - 17 = -7:
abs((-7)/12) - abs(5/3)
Since 5/3 is a non-negative constant, abs(5/3) = 5/3:
abs(-7/12) - 5/3
Since -7/12 is a negative constant, abs(-7/12) = 7/12:
7/12 - 5/3
Put 7/12 - 5/3 over the common denominator 12. 7/12 - 5/3 = 7/12 + (4 (-5))/12:
7/12 - (5×4)/12
4 (-5) = -20:

1. The equilibrium quantity = 60, the equilibrium price = 300
2. If the government imposes the tax of 24, the quantity supplies would fall to 56, and the price would rise to 308
How to solve for equilibriumAt equilibrium we have P = Q
that is price is equal to quantity. Such that we would have:
420-2q = 60+ 4q
take the like terms
420 - 60 = 4q + 2q
360 = 6q
q = 360 / 6
q = 60
The equilibrium quantity = 60 then equilibrium price =
420-2q
420 - 2 * 60
300
The equilibrium price is 300
2. If the government imposes 24 dollar per unit
420-2q = 60+ 4q + 24
420 - 2q = 84 + 4q
420 - 84 = 4q + 2q
336 = 6q
56 = q

A rectangular corral of 117 square meters is to be fenced off and then divided by a fence into two sections, as shown in the figure to the right. If the cost of fencing for the boundary is $10 per meter and the dividing fence costs $6 per meter, find the dimensions of the corral that minimize the cost of the fencing.
Answer:
the dimensions of the corral that minimize the cost of the fencing are approximately 17.91 meters by 6.54 meters.
Step-by-step explanation:
Let the length of the corral be x, and the width be y. We know that the area of the corral is 117, so:
xy = 117
We also know that the corral is divided by a fence into two sections. Let the length of one section be L, and the width be y. Then, the length of the other section will be x - L, and the width will still be y. The total fencing cost will be:
10(2x + 2y) + 6(L + 2y)
Simplifying this expression, we get:
20x + 32y + 6L
Using the area equation, we can rewrite this as:
20x + 32(117/x) + 6L
To minimize the cost, we need to take the derivative of this expression with respect to L, and set it equal to zero:
d/dL [20x + 32(117/x) + 6L] = 6 = 0
Solving for L, we get:
L = x/2
Therefore, the two sections of the corral will have equal length. Substituting this value of L into the expression for total fencing cost, we get:
20x + 32y + 3x
Simplifying this, we get:
23x + 32y
Using the area equation to substitute for y, we get:
23x + 32(117/x)
Taking the derivative of this expression with respect to x, and setting it equal to zero, we get:
23 - 3744/x^2 = 0
Solving for x, we get:
x = sqrt(3744/23) ≈ 17.91
Substituting this value of x into the area equation, we get:
y = 117/x ≈ 6.54
Therefore, the dimensions of the corral that minimize the cost of the fencing are approximately 17.91 meters by 6.54 meters.

A rancher has 600
feet of fencing to put around a rectangular field and then subdivide the field into 3
identical smaller rectangular plots by placing two fences parallel to one of the field's shorter sides. Find the dimensions that maximize the enclosed area. Write your answers as fractions reduced to lowest terms.
The dimensions of the rectangular field that maximize the enclosed area are 150 feet by 75 feet.
What is area?
An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.
Let's call the length of the rectangle "l" and the width "w".
We can write two equations based on the given information -
Perimeter equation: 2l + 4w = 600 (since there are two sets of parallel sides, we have to add an extra "w" to the perimeter equation)
Area equation: A = 3lw (since the field is divided into 3 equal parts)
We want to maximize the enclosed area, which means we want to find the values of "l" and "w" that make the area as large as possible.
We can use the perimeter equation to solve for one of the variables in terms of the other -
2l + 4w = 600
2l = 600 - 4w
l = 300 - 2w
Now we can substitute this expression for "l" into the area equation -
A = 3lw
A = 3(300 - 2w)w
A = 900w - 6w²
To find the maximum area, we can take the derivative of this equation with respect to "w" and set it equal to zero -
dA/dw = 900 - 12w = 0
12w = 900
w = 75
So the width of each of the smaller rectangular plots is 75 feet.
We can use the perimeter equation to find the length -
2l + 4w = 600
2l + 4(75) = 600
2l = 300
l = 150
Therefore, the dimensions value are obtained as 150 feet by 75 feet.

A five-pound bag of potatoes costs $2.95 in a particular store. What is the unit price of the potatoes per ounce?
Therefore, the unit price of the potatoes per ounce is $0.036875.
What is unitary method?The unitary method is a mathematical technique that involves finding a single unit value in order to solve a problem involving multiple units. In other words, the unitary method involves finding the value of one unit of a given quantity, and then using that value to calculate the value of another quantity that is related to it.
Here,
First, we need to convert pounds to ounces since the unit price is usually measured in terms of ounces. There are 16 ounces in one pound, so:
5 pounds = 5 x 16
= 80 ounces
The bag of potatoes costs $2.95 for 80 ounces, so the unit price per ounce can be found by dividing the total cost by the number of ounces:
Unit price per ounce = Total cost / Number of ounces
Unit price per ounce = $2.95 / 80
= $0.036875

I’s it yes or no because you have to justify the answer
Yes, both triangles are similar.
What is similar triangle?Similar triangles are two triangles that have the same shape, but may differ in size. In other words, their corresponding angles are congruent and their corresponding sides are proportional. This means that if you were to scale one triangle up or down, it would still maintain the same shape as the other triangle.
In ΔABC,
AC² = 36² +15²
AC² = 1521 = 39²
AC = 39
In ΔXYZ,
XY² = 24² +10²
XY² = 676 = 26²
XY = 26
If the ratio of the sides of both triangles are similar So we can say that the both triangles are similar.
AB/XZ = BC/YZ = AC/XY
15/10 = 36/24 = 39/26
3/2 = 3/2 = 3/2
Here we can see that the ratio of the sides of both triangles are similar So we can say that the both triangles are similar.
