With placing positive integers around the circle. Yes, there exist three integers in consecutive locations around the circle that have a sum greater than or equal to 17.
What exactly is a circle?
A circle is a kind of ellipse with zero eccentricity and two foci that are coincident. A circle is also known as the locus of points drawn at equal distances from the center. The radius of a circle is the distance from its center to its outside line. The diameter of a circle is the line that divides it into two equal sections and is equal to twice the radius.
The equation for a circle in the plane is:
(x-h)^²+ (y-k)² = r²
When the coordinate points are (x, y)
(h, k) is the coordinate of a circle's center.

Let R be the region bounded by y= square root of 25-x^2 and y=0. Find the volume of the solid of revolution obtained by revolving R about the x-axis.
As a result, the volume of the revolution solid is roughly -62.83π cubic units.
What is volume?Volume is the quantity of space in a 3D object in arithmetic. A fish tank, for example, is 3 feet long, 1 foot wide, and 2 feet tall. To calculate the volume, multiply the length by the breadth by the height, which is 3x1x2, which is six. As a result, the fish tank has a volume of 6 cubic feet.
Here,
The region R is the upper half of a circle centered at the origin with a radius of 5. By the method of washers, the volume of the solid of revolution obtained by revolving R about the x-axis can be found by subtracting the volume of a cylinder of height "h" and radius "x" from the volume of a cylinder of height "h" and radius "sqrt(25-x²)".
The volume of a cylinder of height "h" and radius "r" is given by V = πr²h.
So, the volume of the solid of revolution can be expressed as:
V = ∫π(sqrt(25-x²)²- x²) dx from x=0 to x=5
Evaluating this integral, we get:
V = π(∫(25-x²)*0.5 dx - ∫x² dx) from x=0 to x=5
Using substitution and integrating, we can obtain the volume:
V = π * (5 * (2 * sqrt(25 - x²) - x²/2))
Evaluating the expression at x=5, we get:
V = π * (5 * (2 * sqrt(25 - 25) - 25/2))
V = π * (5 * (0 - 25/2))
V = -62.83π cubic units.
So, the volume of the solid of revolution is approximately -62.83π cubic units.

At a particular restaurant, each onion ring has 40 calories and each pizza roll has 80
calories. A combination meal with pizza rolls and onion rings is shown to have 800
total calories and 4 more pizza rolls than onion rings. Graphically solve a system of
equations in order to determine the number of onion rings in the combination meal,
x, and the number of pizza rolls in the combination meal, y.
As a result, the combo meal includes 4 onion rings and 8 pizza buns.
What is equation?An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.
Here,
Let x be the number of onion rings in the combination meal and y be the number of pizza rolls. We can write the following system of equations to represent the given information:
40x + 80y = 800 (the total calories of the meal)
y = x + 4 (the number of pizza rolls is 4 more than the number of onion rings)
We can substitute the second equation into the first equation to solve for x:
40x + 80(x + 4) = 800
40x + 80x + 320 = 800
120x = 480
x = 4
We can use this value to find y:
y = x + 4 = 4 + 4 = 8
So, the combination meal contains 4 onion rings and 8 pizza rolls.

From a sample with n=12, the mean number of television per household is 3 with a standard deviation of 1 television. Using Chebychev Theorem,determine at least how many of the households have between 1 and 5 televisons
Answer:
9
Step-by-step explanation:
Chebyshev's Theorem states that for any given sample, at least 1 - 1/k^2 of the data falls within k standard deviations from the mean.
Let's use k = 2. Then, at least 1 - 1/2^2 = 1 - 1/4 = 3/4 of the households should have between 3 - 2 = 1 and 3 + 2 = 5 televisions.
So, at least 12 * 3/4 = 9 of the households in the sample have between 1 and 5 televisions.

Wendy will have new carpet installed on her rectangular bedroom floor. The floor is 15 feet in length and 12 feet in width. The carpet costs $27.50 per square yard, and installation costs $4.15 per square yard. Which statement about the total cost of the carpet and installation is true?
a. The total cost is $379.80 since $31.65×12 = $379.80.
b. The total cost is $633.00 since $31.65×20 = $633.00.
c. The total cost is $474.75 since $31.65×15 = $474.75.
d. The total cost is $4,950.00 since $27.50×180 = $4,950.00
Answer: The statement "d. The total cost is $4,950.00 since $27.50×180 = $4,950.00" is incorrect.
The first step is to convert the dimensions of the floor from feet to yards. Since 1 yard = 3 feet, the length of the floor is 15 feet / 3 feet/yard = 5 yards, and the width of the floor is 12 feet / 3 feet/yard = 4 yards. The total area of the floor is 5 yards * 4 yards = 20 square yards.
The total cost per square yard for carpet and installation is $27.50 + $4.15 = $31.65.
The total cost for carpet and installation for the entire floor is 20 square yards * $31.65/square yard = $633.00.
So, the statement "b. The total cost is $633.00 since $31.65×20 = $633.00" is correct.

What is the probability that a randomly selected person aged 40 years or older is female and smokes?B. Would it be unusual to randomly select a person aged 40 years or older who is female and smokes?
A. The probability that a randomly selected person aged 40 years or older is female and smokes is 0.05841.
B. No, it would not be unusual to randomly select a person aged 40 years or older who is female and smokes.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
When given an event A and an event B, the conditional probability that A will occur given than B has occurred is calculated using this formula -
P(A|B) = P(A and B) / P(B)
Let A be that the person is female and B be that they smoke. It is known that P(B) = 0.295 and let P(A|B) = 0.198.
Use the formula for conditional probability -
0.198 = P(A and B) / 0.295
P(A and B) = 0.198 × 0.295
P(A and B) = 0.05841
The probability that a person aged 40 years or older is female and smokes would happen is 0.05841, which is not less than the usual benchmark of 0.05 to be considered unusual.
Therefore, no, this would not be unusual.

how do you find the range algebraically?? Please and thank you if you reply
Answer:
[9, 9+√18.25] ≈ [9, 13.272]
Step-by-step explanation:
You want the range of f(x)= 9+√(6+7x-x^2), determined algebraically.
RangeThe range is the set of values that f(x) may take on. It is the vertical extent of the graph. Here, it will be limited by the possible values the radical may have.
The expression under the radical is a quadratic that opens downward. It will have a maximum at its vertex, and a minimum usable value of 0.
The vertex of the quadratic can be found by putting it in vertex form:
-x² +7x +6 = -(x² -7x) +6 = -(x² -7x +(7/2)²) +6 +(7/2)² = -(x -7/2)² +18.25
The maximum value the quadratic may have is 18.25.
Then the range of values that f(x) may have is ...
9 +0 ≤ f(x) ≤ 9 +√18.25
The range is [9, 9+√18.25] ≈ [9, 13.272].

The graph of the function g(x) = a |x| includes the point (1, 16). What is another point on the graph of the function? What is the value of a?
The graph of the function g(x) = a |x| includes the point (1, 16). (-1, 16) is another point on the graph of the function.
What is function?Exactly one element of Y is assigned to each element of X in a mathematical function from a set X to a set Y. Both the set X and the set Y are referred to as the function's domain and co-domain, respectively. The basic conception of functions was the relationship between fluctuating quantities and other variables.
Given that,
g(x) = a |x|
In a absolute value graph the value of y is the same in -x and x.
Then if the coordinates (x,y) one point is (1, 16), the graph have another point in (- 1, 16).
To find the value of a you use one of the points (x,y) in the general form of absolute value:
( 1 , 16) x = 1 f(x) = y = 16
16 = a | 1 |
As, |±a| = a
we get:
16 = a . 1
then, a = 16
The equation for the graph with points (1 , 16) and ( -1, 16) is:
g(x) = 16 |x|
a = 16

The equation __________ models the balance y after x months.
(Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation. Do not include the $ symbol in your answer.)
Answer:
Equation: y = 1800 - 120x
Step-by-step explanation:
y = 1800 - mx Where x = months after purchase of computer
y = balance remaining
1800 = y-intercept because this is your initial balance remaining as it is the actual price of the computer.
The coefficient of ‘m’ will be negative for this equation because the value of y decreases as x increases. (NOTE: y is NOT indirectly proportional to x as the line of the equation does not pass through the origin)
Next step is to determine 'm’:
m = slope of equation
Two sets of x and y values have been provided:
[tex](x_{2}, y_{2}) = (3, 1440)[/tex]
[tex](x_{3} ,y_{3})= (6, 1080)[/tex]
Use any set and substitute in the slope-intercept equation to determine the value of m:
1080 = 1800 - 6m
All the like terms are brought together and m needs to be isolated:
6m = 1800 - 1080
6m = 720
m = [tex]\frac{720}{6}[/tex]
m = 120
Therefore:
y = 1800 - 120x
