What is an equation?An equation is an expression that contains numbers and variables linked together by mathematical operations of addition, subtraction, multiplication, division and exponents. An equation can either be linear, quadratic, cubic, depending of the degree of the variable.
Trigonometric ratio is used to show the relationship between the sides and angles of a right triangle.
Let h represent the height of the mountain. Let d represent the distance from the plain to the mountain base
Using trigonometric ratio:
tan(32) = h/d
h = d * tan(32)
Also:
tan(36) = h / (d - 1000)
h = (d - 1000) * tan(36)
Equating:
d * tan(32) = (d - 1000) * tan(36)
d = 7145.9 feet
h = d * tan(32) = 7145.9 * tan(32) = 4465.2 feet

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?
Answers
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.

What is the solution to the given equation?Given the equation in the question;
5x - 2 + x = 9 + 3x + 10
Solve for x, first collect and add like terms
5x - 2 + x = 9 + 3x + 10
5x + x - 2 = 3x + 10 + 9

how do you find the range algebraically?? Please and thank you if you reply
Answers
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].
A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 20% off clearance items. What percent of the original price do you end up paying?
Answers
The required, we end up paying 60% of the original price.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
If an item is marked down by 25%, then its sale price is 75% of its original price.
If the sale offers an additional 20% off clearance items, then the final sale price is 80% of the sale price.
Multiplying these two percentages, we get:
Final price = 80% of 75% of the original price
Final price = 0.80 × 0.75 × original price
Final price = 0.6 × original price
So the final price that you pay is 60% of the original price.
Therefore, we end up paying 60% of the original price.

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

let the random variable Y possess a uniform distribution on the interval(0,1). Derive the
a) distribution of the random variable W=Y^2
b) distribution of the random variable W=Y^(1/2)
Answers
To derive the distribution of W, we need to find the cumulative distribution function (CDF) of W, F_W(w), and then find its probability density function (PDF), f_W(w).
a) The distribution of the random variable W = Y^2:
The cumulative distribution function (CDF) of W is given by F_W(w) = P(W <= w), where W is the random variable defined as W = Y^2.
Since Y has a uniform distribution on the interval (0,1), its CDF is given by:
F_Y(y) = 0, for y < 0.
= y, for 0 <= y <= 1.
= 1, for y > 1.
Therefore, the CDF of W = Y^2 is:
F_W(w) = P(Y^2 <= w)
= P(0 <= Y <= sqrt(w))
= F_Y(sqrt(w))
= sqrt(w), for 0 <= w <= 1.
= 1, for w > 1.
Thus, the CDF of W is a monotonically increasing function that maps the interval [0, 1] to [0, 1].
The probability density function (PDF) of W is given by f_W(w) = dF_W(w)/dw. The PDF of W can be found by differentiating the CDF:
f_W(w) = dF_W(w)/dw
= d(sqrt(w))/dw
= 1/(2*sqrt(w))
f_W(w) is defined only for 0 <= w <= 1.
b) The distribution of the random variable W = Y^(1/2):
The CDF of W = Y^(1/2) is given by F_W(w) = P(W <= w), where W is the random variable defined as W = Y^(1/2).
Using the same argument as in part (a), we have:
F_W(w) = P(Y^(1/2) <= w)
= P(0 <= Y <= w^2)
= F_Y(w^2)
= w^2, for 0 <= w <= 1.
= 1, for w > 1.
The PDF of W = Y^(1/2) can be found by differentiating the CDF:
f_W(w) = dF_W(w)/dw
= d(w^2)/dw
= 2w
f_W(w) is defined only for 0 <= w <= 1.

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
Answers
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.

Answers
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.

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.

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (0, 5) and (8, -2).
Now,
Since, The equation of line passes through the points (0, 5) and (8, -2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - 5) / ( 8 - 0)
m = - 7 / 8
Thus, The equation of line with slope - 7/8 is,
⇒ y - 5 = - 7/8 (x - 0)
⇒ y - 5 = - 7/8x
⇒ y = - 7/8x + 5
Therefore, The y - intercept of the graph is, 5

(b)The area of a rectangular window is 6789 cm².
If the width of the window is 73 , what is its length?
Answers
Answer:
93cm
Step-by-step explanation:
6789 = 73 * length
length = 6789/73=93
Answer:
The length is 93 cm.
Step-by-step explanation:
We know that area is width times height. So, if we don't know what the length is,
Let x = the length
The equation would be
[tex]73x=6789\\[/tex]
We multiply 73 by x because of the formula talked about previously.
Now, lets divide 73 on both sides
[tex]x = 93[/tex]
