At 100 machines the unit cost will be minimum and the minimum cost is 11985.

Finding the maximum and minimum on parabolas:

The lowest point on the graph, that is referred to as the minimum, or min, is the vertex of a parabola. The highest point on the graph, that referred to as the maximum, or max, is the vertex of a parabola.

The formula for the minimum value is given by -b/2a

Here we have

The medical equipment industry manufactures X-ray machines. If x machines are made, the unit cost is given by the function
C(x) = 0.9x²-180x+20,985.  

Compare given C(x) with the standard equation ax² + bx + c  

=> a = 0.9, b = -180 and c = 20,985  

We can find the x - coordinate where the minimum value occurs using the formula -b/2a    

The x-coordinate where the minimum value occurs = - (- 180)/2(0.9)

= (180)/1.8 = 100

Hence at x = 100, the unit cost will be minimum

The unit cost can be calculated as follows

C(100) = 0.9(100)²-180(100)+20,985

= 0.9(10000) -18000 + 20,985    

= 9000 - 18000 + 20985

= 11985

Therefore,

At 100 machines the unit cost will be minimum and the minimum cost is 11985.

Jayden wants to lay sod on his front yard and on half of his back yard. His front yard has a length of 50 feet and a width of 70 feet. His back yard has a length of 10 feet and a width of 40 feet. How many square feet of sod does Jayden need to purchase?

Answers

Jayden needs to purchase 3900 square feet of sod to cover his front and back yards.

The unitary method is a mathematical technique used to solve problems by finding the value of one unit and then multiplying or dividing to find the value of the whole. In this case, the unit we will use is square feet.

To calculate the area of the front yard, we need to multiply its length by its width. So, we have:

Area of front yard = Length x Width = 50 ft x 70 ft = 3500 sq ft

To find the area of the back yard, we use the same formula:

Area of back yard = Length x Width = 10 ft x 40 ft = 400 sq ft

Now, we need to add the two areas to find the total area that requires sod. So, we have:

Total area = Area of front yard + Area of back yard

=> 3500 sq ft + 400 sq ft = 3900 sq ft

Q9.
Gavin bought 3 pairs of jeans in the USA.
He paid a total of $72
Gavin sold the 3 pairs of jeans in England,
He sold each pair of jeans for £34.50
£1 = $1.34
Work out Gavin's percentage profit.
Give your answer correct to the nearest whole number.

Answers

Answer:

Gavin made a Profit of $66.69 that is 93% Profit

Step-by-step explanation:

First, we calculate the Selling Price of Jeans after converting from GBP to USD on the given rate:

Rate: £1 = $1.34

Quantity: 3

Price in USD = Selling Price per pair * Rate in USD

£34.50 * 1.34 = $46.23 per pair of jeans.

Total Selling Price = Price Per Pair * Quantity
= 46.23 * 3
= $138.69

Total Profit = Total Selling Price - Total Cost Price
= $138.69-$72
= $66.69

Percentage of Profit = Total Profit / Total Cost Price
=66.69 / 72
=92.65

Therefore, the Profit Percentage is 92.65 % the nearest whole number would be 93%





Final answer:

To calculate Gavin's percentage profit, find the difference between the selling price and the buying price, and calculate the percentage of the buying price that the profit represents.

Explanation:

To calculate Gavin's percentage profit, we need to find the difference between the selling price and the buying price, and then calculate the percentage of the buying price that the profit represents.

First, convert the selling price of each pair of jeans from pounds to dollars. Since £1 = $1.34, each pair of jeans sold for $34.50 x 1.34 = $46.23.Next, calculate the total selling price by multiplying the selling price of each pair by the number of pairs: $46.23 x 3 = $138.69.Then, calculate the profit by subtracting the total buying price from the total selling price: $138.69 - $72 = $66.69.Finally, calculate the percentage profit by dividing the profit by the total buying price and multiplying by 100: ($66.69 / $72) x 100 ≈ 92.6%.

Gavin's percentage profit is approximately 92.6%.

3. A golfer hits an errant tee shot that lands in the rough. A marker in the center of the fairway is 150
yards from the center of the green. Whilestanding on the marker facing the green, the golfer turns
110 toward his ball. He then paces off 35 yards to hit his ball. See figure. How far is the ball from the
center of the green? Round to the nearest yard

Answers

We can use the Pythagorean theorem to solve this problem. Let's call the distance from the ball to the center of the green "d". We know that the marker is 150 yards from the center of the green, and the golfer has paced off 35 yards in a direction 110 degrees from the marker.

Let's use x to represent the horizontal distance from the marker to the ball, and y to represent the vertical distance from the marker to the ball. Then, we have:

x = 35 * cos(110)

y = 35 * sin(110)

Using the Pythagorean theorem, we can find the distance "d" from the ball to the center of the green:

d^2 = x^2 + (y + 150)^2

Plugging in the values for x and y, we get:

d^2 = 35^2 * cos(110)^2 + (35 * sin(110) + 150)^2

d^2 = 1225 + (150 + 35 * sin(110))^2

Using a calculator, we can find that sin(110) = 0.939, so:

d^2 = 1225 + (150 + 31.65)^2

d^2 = 1225 + (181.65)^2

d^2 = 1225 + 32762.7225

Taking the square root of both sides:

d = sqrt(1225 + 32762.7225)

d = sqrt(33987.7225)

d = 183.83

Rounding to the nearest yard:

d = 184 yards

So, the ball is 184 yards from the center of the green.

if the test in problem 1 had been performed in a primary care setting (instead of a hospital) with a baseline cervical cancer prevalence of 15%, what would have been the test performance? for this, you need to use the same sensitivity and specificity values obtained in the study, but apply them to a different population with 15% prevalence of cervical cancer. use the blank tables given below. assume that the same number of patients is screened (3,300). round to the nearest whole number when making calculations.

Answers

In a primary care setting with a baseline cervical cancer prevalence of 15%, the screening test would have a sensitivity of 94.3% and a specificity of 85.7%. The PPV would be 53.1% and the NPV would be 98.8%.

To calculate the test performance of the screening test in a primary care setting with a 15% baseline cervical cancer prevalence,

we can use the same sensitivity and specificity values obtained in the study, but apply them to a different population.

Given that the prevalence of cervical cancer is 15%, the number of true positives (TP) and false negatives (FN) in the screened population would be:

TP = Prevalence x Sensitivity x Number screened

TP = 0.15 x 0.91 x 3300

TP = 449.19, rounded to 449.

FN = Number with disease - TP

FN = 0.15 x 3300 - 449

FN = 26.5, rounded to 27.

Similarly, the number of true negatives (TN) and false positives (FP) in the screened population would be:

TN = (1 - Prevalence) x Specificity x Number screened

TN = 0.85 x 0.85 x 3300

TN = 2382.75, rounded to 2383.

FP = Number without disease - TN

FP = 0.85 x 3300 - 2383

FP = 396.5, rounded to 397.

Using these values, we can construct the following 2x2 contingency table for the primary care setting:

Actual condition:-

Test outcome       Positive (P)                          Negative (N)

Disease (D)       True positive (TP = 449)         False negative (FN = 27)

No disease (ND) False positive (FP = 397)  True negative (TN = 2383)

Using this contingency table, we can calculate the following test performance measures:

Sensitivity = TP / (TP + FN) = 449 / (449 + 27) = 0.943, or 94.3%.

Specificity = TN / (FP + TN) = 2383 / (397 + 2383) = 0.857, or 85.7%.

Positive predictive value (PPV) = TP / (TP + FP) = 449 / (449 + 397) = 0.531, or 53.1%.

Negative predictive value (NPV) = TN / (FN + TN) = 2383 / (27 + 2383) = 0.988, or 98.8%.

Therefore, in a primary care setting with a baseline cervical cancer prevalence of 15%, the screening test would have a sensitivity of 94.3% and a specificity of 85.7%. The PPV would be 53.1% and the NPV would be 98.8%.

there is a common difference between consecutive terms in the sequence

7 - 1 = 13 - 7 = 19 - 13 = 6

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

It is a point that divides a segment into two congruent segments.
A.Point
B.Midpoint
C.Bisector
D.Ray​

Answers

The point that divides a segment into two congruent segments is called the midpoint. Therefore, the answer is B) midpoint.

In geometry, a midpoint is a point that divides a line segment into two equal parts. It is the point on the line segment that is equidistant from both endpoints. The midpoint is important in geometry as it can be used to construct other geometric figures, such as perpendicular bisectors, which are lines that pass through the midpoint of a line segment and are perpendicular to it. For example, if we have a line segment AB, the midpoint M is the point that is exactly halfway between A and B, such that AM = MB. This can be found by drawing a perpendicular bisector of AB, which is a line that passes through the midpoint M and is perpendicular to AB. The perpendicular bisector will intersect AB at the midpoint M. It is important to note that the midpoint is not a bisector, ray, or point on a line. A bisector is a line, segment, or ray that divides an object into two congruent parts, while a ray is a part of a line that extends infinitely in one direction. The midpoint is simply the point that divides a line segment into two equal parts, and it is denoted by a symbol, such as a small vertical line with a hat on top, or by labeling the midpoint as a letter, such as M in the example above

sin θ = y / r

cos θ = x / r

tan θ = y / x

Where:

x, y - Legsr - Hypotenuse.

Please notice that hypotenuse is the longest side of a right triangle.

The first five cases implies the determination of missing lengths in five right triangles:

x = 24.111

The following five cases implies the determination of angles by means of direct and inverse trigonometric functions:

Case 6

tan θ = 16 / 26

tan θ = 8 / 13

θ = 31.608° (32°)

Case 7

tan θ = 6 / 10

θ = 30.964° (31°)

Case 8

tan θ = 76 / 26

θ = 71.114° (71°)

Case 9

tan θ = 67 / 23

θ = 71.053° (71°)

Case 10

tan θ = 26 / 42

θ = 31.759° (32°)

8) x ≈ 71°

9) x ≈ 71°

10) x ≈ 32°

11) cos(A) ≈ 0.9

What are trigonometric ratios?

Trigonometric ratios are expressions that specify the relationships between two sides of a right triangle and an interior angle of the triangle.

1) The opposite side = 20 × sin(19°) ≈ 6.5

The adjacent side = 20 × cos(19°) ≈ 18.91

2) cos(30°) = 20/x

cos(30°) = (√3)/2, therefore;

(√3)/2 = 20/x

x = 20/((√3)/2) = 40·√3/3 ≈ 23.1

x ≈ 23.1

3) cos(51°) = 10/x

Therefore;

x = 10/(cos(51°)) ≈ 15.9

4) tan(42°) = 15/x

Therefore;

x = 15/(tan(42°)) ≈ 16.7

x ≈ 16.7

5) sin(52°) = 19/x

Therefore;

x = 19/(tan(52°))

x = 20/(cos(30°)) ≈ 23.1

x ≈ 23.1

6) tan(x) = 16/26

A group of students atten a math club. Half of them students are boys 4/9 of them boys have brown eyes

Answers

The fraction of the group are boys with brown eyes with total group of students who attend the math club is equals to the 2/9.

Let us assume that total number of students who attend the math club be 'x'. Now, according to problem, half of students who attend the math are boys. So, boys students out of total students who attend the math club, B = ( 1/2)x --(1)

Also, 4/9 of them boys have brown eyes. That is the boys students have brown eyes out of boys students who attend the math club, E = 4/9 of B

=> (4/9)B --(2)

We have to determine the relationship between boys with brown eyes (E) and the group of students (x). so, let's replace B in second equation with the expression present in eqution (1).

=> E = (4/9)(x/2)

For simplification, multiply the two fractions, that denominator with denominator and numerator with numerator.

=> E = 4x/18

For further simplification, simply dividing both the numerator and denominator by their common factor, ( 4, 18 ) = 2,

=> E = 2x/9

so, the required relationship between E and x is 2/9. Hence, required value is 2/9.

S164.219
$99.200

Answers

Answer: $212,019 to raise a child from birth to 17 years in a household with an annual income of $64,000.

Explanation:

To find out the total cost of raising a child in a household with an annual income of $64,000, we can plug in x = 64,000 into the equation y = 1.55x + 110,419:

y = 1.55x + 110,419

y = 1.55 * 64,000 + 110,419

y = 101,600 + 110,419

y = $212,019

So, it would approximately cost $212,019 to raise a child from birth to 17 years in a household with an annual income of $64,000.

Find the distance between the two points
rounding to the nearest tenth (if
necessary).
(3,-4) and (9,-9)

Answers

The distance between the given pair of points (3,-4) and (9,-9) is 7.8 unit.

What is the distance between the given pair of points?

The distance formula used in finding the distance between two points is expressed as;

D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )

Given the data in the question;

Point 1 ( 3,-4 )

x₁ = 3y₁ = -4

Point 2 ( 9,-9 )

x₂ = 9y₂ = -9

Plug the given values into the distance formula and simplify.

D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )

D = √( ( 9 - 3 )² + ( -9 - (-4) )² )

D = √( ( 9 - 3 )² + ( -9 + 4 )² )

D = √( ( 6 )² + ( -5 )² )

D = √( 36 + 25 )

D = √( 61 )

D = 7.8 units

Therefore, the distance between the of points is 7.8 units.

On a test that has a normal distribution, a score of 34 falls two standard deviations above the mean, and a score of 22 falls one standard deviation below the mean. Determine the mean of this test.

Answers

The mean of this data set is 65.

What is the mean absolute deviation?

The average distance between each data item and the mean is known as the mean absolute deviation.

The gap between each data value and the mean in absolute terms is represented by this average.

Let the mean be 'x' and the standard deviation be 'y'

3 standard deviations the mean means that we are taking away 3 standard deviations from the mean

Mathematically, we have that as;

x - 3y = 41...(i)

73 is 1 standard deviation above the mean

Mathematically;

x + y = 73...(ii)

So let us solve both equations simultaneously

Simply multiply equation (ii) by 3 then add to (i)

x - 3y = 41

3x + 3y =219

4x = 41 + 219

4x = 260

x = 260/4

x = 65.

The equation of line shown on the coordinate plane is,

⇒ y = - 1/4x

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, 0) and (4, -1).

Now,

Since, The equation of line passes through the points (0, 0) and (4, -1).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 1 - 0) / (4 - 0)

m = - 1 / 4

Thus, The equation of line with slope - 1/4 is,

⇒ y - 0 = - 1/4 (x - 0)

⇒ y = - 1/4x

Therefore, The equation of line passes through the points (0, 0) and

(4, -1) will be;

⇒ y = - 1/4x

Suppose p and q vary inversely and p = 14 when a = 4 Find p when q = 8 please show work

Answers

If p and q vary inversely and p = 14 when a = 4, then the work is  q = 8, p = 7.

What is inverse proportionality?

Inverse proportionality occurs when x increases and y decreases, and when x decreases and y increases.

If p and q vary inversely, this means that their product is constant:

p * q = k

where k is a constant. We can use this relationship to solve the problem.

We are given that when a = 4, p = 14. This means that:

p * a = k

14 * 4 = k

56 = k

So we know that the product of p and a is 56.

To find p when q = 8, we can use the fact that p and q vary inversely. This means that:

p * q = k

We know that k = 56, so we can substitute:

p * q = 56

We are given that q = 8, so we can substitute this as well:

p * 8 = 56

Solving for p, we get:

p = 56 / 8 = 7

Therefore, when q = 8, p = 7.

A building casts a 103-foot shadow at the same time that a 32-foot flagpole casts as 34. 5-foot shadow. How tall is the building (Round your answer to the nearest tenth. )

Answers

A building casts a 103-foot shadow at the same time that a 32-foot flagpole casts as 34. 5-foot shadow then the building is approximately 95.2 feet tall.

What is similar triangles ?

Similar triangles are useful in geometry and other fields because they allow us to solve problems involving unknown distances or heights. We can use the known lengths and angles of one triangle to find the lengths and angles of the other triangle, as long as we know that the two triangles are similar. This can be done using the properties of proportional relationships and the rules of similar figures.

Let's use similar triangles to solve this problem. The height of the building and the height of the flagpole are proportional to the lengths of their shadows. We can set up the following equation:

height of building / length of building's shadow = height of flagpole / length of flagpole's shadow

Let x be the height of the building. Then we have:

x / 103 = 32 / 34.5

Simplifying this equation, we get:

x = 103 * (32 / 34.5) ≈ 95.23

Therefore, the building is approximately 95.2 feet tall.
