What is equation?

A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another.

For the predicament, the following input values would be suitable:

B) 1

C) 2

D) 3

E) 4

As the temperature drops by around 5°F for every 1,000 feet of height, we must utilise altitude numbers in thousands of feet to obtain the function's proper input values. Hence, we would utilise a value of 1 as an input for every 1,000 feet of height rise. Consequently, 1, 2, 3, and 4 would be the proper input values, which correspond to altitudes of 1,000, 2,000, 3,000, and 4,000 feet, respectively. The input value 0 represents the height at sea level, making it an inappropriate value for this function.

1. A wholesaler received a shipment of goods, which is reported to be containing at most 2% defective items. He will accept the shipment if the claim is found true and reject if the percentage of defective items is more. To verity this claim, he draws a sample of 200 items and finds that 10 items are defective. Use 5% level of significance to investigate the claim.

Answers

At a 5% level of significance, the claims that a shipment of goods contains at most 2% defective items is accepted.

To investigate the claim that the shipment contains at most 2% defective items, we can use the 5% level of significance. The claim is that the population proportion of defective items is at most 2%, or p0 ≤ 0.02. The sample size is n = 200, and the sample proportion of defective items is pobs = 10/200 = 0.05.

The test statistic is then:

z = (pobs - p0) / √(p0(1-p0) / n)

= (0.05 - 0.02) / √(0.02(1-0.02)/200)

= 1.02.

With a 5% level of significance, we can look up the critical value for a one-tailed z-test and find that it is zα/2 = 1.645. Because 1.02 < 1.645, the test statistic is not greater than the critical value, and thus we fail to reject the null hypothesis that the population proportion of defective items is at most 2%.

In conclusion, with a 5% level of significance, the claim that the shipment contains at most 2% defective items is accepted.

Find angle A on a triangle when A(5x-1) B is unknown and C(2x)?

Answers

Answer:

  ∠A = 64°

Step-by-step explanation:

You have a triangle inscribed in a semicircle with acute angles marked A=(5x-1)° and C=(2x)°.

Right triangle

A triangle inscribed in a semicircle is a right triangle. (You know that because angle B is half the measure of 180° arc AC.) That means the two marked angles total 90°:

  (5x -1) +(2x) = 90

  7x = 91

  x = 13

Then angle A is ...

  A = (5·13 -1)° = (65 -1)° = 64°

The measure of angle A is 64°.

__

Check:

  C = (2x)° = (2·13)° = 26°

Then A+C = 64° +26° = 90°, as required.

2. IF TEST SCORES ARE NORMALLY DISTRIBUTED WITH A MEAN OF 84 AND A STANDARD DEVIATION OF 9. PLEASE FIND THE PROBABILITY A STUDENT SCORED BETWEEN 75 AND 89.
3. FIND THE PROBABILITY A STUDENT SCORED ABOVE 85.

Answers

The expected value of the game in which you have a (1/20) chance of winning  is $1.50.  The probability of a student scoring between 75 and 89 is 0.5536. The probability of a student scoring above 85 is 0.4562.

1. To find the expected value of the game, we need to multiply the probability of each outcome by the value of that outcome and then add them together.

E(X) = (1/20)($300 + $15) + (19/20)(-$15)

E(X) = $315/20 - $285/20

E(X) = $30/20

E(X) = $1.50

So the expected value of the game is $1.50.

2. To find the probability of a student scoring between 75 and 89, we need to use the z-score formula:

z = (x - μ)/σ

For x = 75, z = (75 - 84)/9 = -1

For x = 89, z = (89 - 84)/9 = 0.56

Using a z-table, we can find the probability of a student scoring between these two z-scores:

P(-1 < z < 0.56) = P(z < 0.56) - P(z < -1)

P(-1 < z < 0.56) = 0.7123 - 0.1587

P(-1 < z < 0.56) = 0.5536

So the probability of a student scoring between 75 and 89 is 0.5536.

3. To find the probability of a student scoring above 85, we need to use the z-score formula:

z = (x - μ)/σ

For x = 85, z = (85 - 84)/9 = 0.11

Using a z-table, we can find the probability of a student scoring above this z-score:

P(z > 0.11) = 1 - P(z < 0.11)

P(z > 0.11) = 1 - 0.5438

P(z > 0.11) = 0.4562

So the probability of a student scoring above 85 is 0.4562.

The scale factor of two similar hexagons is 3:7.

The area of the smaller hexagon is 18 m2.

What is the volume of the larger hexagon?

Question 7 options:

5832 m2


36 m2


42 m2


324 m2


98 m2

Answers

Since the two hexagons are similar, their corresponding sides are in the same ratio as the scale factor.

Let x be the length of a side of the smaller hexagon, then the corresponding length of a side of the larger hexagon can be expressed as (3/7)x.

The area of a hexagon can be calculated using the formula: A = (3√3/2)s², where s is the length of a side.

Since the area of the smaller hexagon is 18 m², we can solve for x as follows:

18 = (3√3/2)x²

x² = 12/√3

x = 2√3

Now we can calculate the area of the larger hexagon:

Area of the larger hexagon = (3√3/2)(3/7x)² = (3√3/2)(3/7(2√3))² = 54/49 m²

Finally, we can calculate the volume of the larger hexagon, assuming it is a regular hexagonal prism:

Volume of the larger hexagon = Area of hexagon x Height

The height of the hexagonal prism is the same as the length of the side of the larger hexagon, which is (3/7)x:

Volume of the larger hexagon = (54/49) x (3/7)x = 54/343 x² ≈ 0.212 x²

Substituting the value of x, we get:

Volume of the larger hexagon ≈ 0.212 x (2√3)² = 1.272 m³

Therefore, the volume of the larger hexagon is approximately 1.272 m³.

Well, I'm not sure if it's correct but I got 42.

I got this by doing something along the lines of:

1) 18/x = 3/7

2) Cross multiply

3) 3x = 126

4) Divide both sides by 3

5) x = 42

[tex](x-x_{1})^2+(y-y_{1})^2=r^2[/tex]

x1 and y1 is the point of the center of the circle, which in this case is (1,-2)

r represents the radius, which is the distance from the center to the edge of the circle, which is (4,-2) - (1,-2) = 3

Our equation is now:

[tex](x-1)^2+(y+2)^2=9[/tex]

the reason why its y+2 is because (y-(-2) = (y+2)

r is squared, which is why it's 9 instead of 3. Hope this helps!

If Emma needs to travel a distance of 15 miles or less, she should choose the red cab company because it has a lower cost. If she needs to travel more than 15 miles, she should choose the yellow cab company  

Determining the company that minimizes cost

From the question, we are to determine which company Emma should use when she wants to minimize cost.

Let's assume that Emma needs to travel a distance of d miles to get to the airport.

The cost C of taking the red cab company can be represented by the function:

Cred(d) = 3.50 + 1.25d

Similarly, the cost C of taking the yellow cab company can be represented by the function:

Cyellow(d) = 5.00 + 1.15d

To determine which company Emma should use to minimize cost, we need to find the value of d that makes the cost of each company equal. In other words, we need to solve the equation:

Cred(d) = Cyellow(d)

Substituting the expressions for Cred(d) and Cyellow(d), we get:

3.50 + 1.25d = 5.00 + 1.15d

Simplifying and solving for d, we get:

0.10d = 1.50

d = 15

Hence, if Emma needs to travel a distance of 15 miles or less, she should choose the red cab company because it has a lower cost. If she needs to travel more than 15 miles, she should choose the yellow cab company.

vIf the slope of a line is 32, how much vertical change will be present for a horizontal change of 96ft?

Answers

A horizontal change of 96ft, there will be a vertical change of 3072ft.

The slope of a line is the ratio of the vertical change to the horizontal change between two points on the line. In other words, the slope is the rise over the run.

If the slope of a line is 32, that means that for every 1 unit of horizontal change, there is a 32 unit vertical change.

So, if the horizontal change is 96ft, we can use the slope formula to find the vertical change:

Vertical change = slope × horizontal change

Vertical change = 32 × 96

Vertical change = 3072

Therefore, for a horizontal change of 96ft, there will be a vertical change of 3072ft.

The response to the given question would be that The slope of the line is the constant of proportionality if the graph is a straight line through the origin.

what is proportionality?

Partnerships that have the same ratio across time are said to be proportional. For instance, how many trees there are in an orchard and how many apples there are in a harvest of apples are determined by the average number of apples per tree. Proportional in mathematics refers to a linear connection between two numbers or variables. As the first quantity doubles, so does the other. When one of the variables drops to 1/100th of its previous value, the other also decreases. When two quantities are proportional, it means that as one rises, the other rises as well, and the ratio between the two quantities stays the same at all levels. As an example, consider the diameter and circumference of a circle.  

It is difficult to estimate the constant of proportionality between two variables, y and x, without first viewing the graph.

Nevertheless, the constant of proportionality may be calculated by dividing any y-value by its corresponding x-value if the two variables are directly proportional, which means that when x rises, y rises as well at a consistent pace.

If y = kx, where k is the proportionality constant, then mathematically, k = y/x at every point on the graph.

What is the minimum value of the function?

Enter your answer in the box. ​

Answers

Step-by-step explanation:

The given function is a quadratic function with a positive leading coefficient, therefore it opens upwards and has a minimum value. To find the minimum value of the function, we can use the formula:

x = -b/2a

where a = 1 and b = 6 are the coefficients of the quadratic function.

x = -6/2(1) = -3

Substitute x = -3 into the function to find the minimum value:

f(-3) = (-3)^2 + 6(-3) + 11 = 2

Therefore, the minimum value of the function is 2.

Answers

A function is given. g(x)=3−4/5x; x=−5 ,x=4 the net change between the given values of the variable is -7.2. The average rate of change between the given values of the variable is -0.8.

(a) To determine the net change between the given values of the variable, we need to find the difference between the function values at x = -5 and x = 4.

g(-5) = 3 - 4/5(-5) = 3 + 4 = 7
g(4) = 3 - 4/5(4) = 3 - 3.2 = -0.2

Net change = g(4) - g(-5) = -0.2 - 7 = -7.2

(b) To determine the average rate of change between the given values of the variable, we need to find the slope of the secant line between the points (-5, 7) and (4, -0.2).

Average rate of change = (g(4) - g(-5))/(4 - (-5)) = (-7.2)/(9) = -0.8

Therefore, the average rate of change between the given values of the variable is -0.8.

find the sine of angle C in this triangle.

Answers

The sine of angle C is √30/10.

Trigonometric ratios:

Trigonometric ratios are mathematical expressions used to relate the angles and sides of a right-angled triangle.

Sine = Opposite / Hypotenuse

Cosine  = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent  

are the fundamental ratios in a right-angle triangle  

where

"Opposite" refers to the side opposite to the angle.

"Adjacent" refers to the side adjacent to the angle.

"Hypotenuse" refers to the longest side of the right-angled triangle

Here we have  

A right-angle triangle DCB  

Where DC = 10 units, CB = √70  

From trigonometric ratios,

Sin θ =  Opposite side/ Hypotenuse

Sin C = DB/CD

By the Pythagorean theorem  

=> DC² = CB² + DB²  

=> (10)² = (√70)² + DB²

=> 100 = 70 + DB²

=> DB² = 100 - 70

=> DB = √30

Sin C = √30/10

Therefore,

The sine of angle C is √30/10.

The area of a circle is 1.1304 square kilometers. What is the circle's diameter? Use 3.14 for ​.

Answers

Answer:

Step-by-step explanation:

the diameter of the circle is approximately 1.2 kilometers.

We can use the formula for the area of a circle:

Area = pi x (diameter/2)^2

where pi is a constant approximately equal to 3.14, and diameter is the distance across the circle passing through its center.

We are given the area of the circle as 1.1304 square kilometers, so we can substitute this value into the formula and solve for diameter:

1.1304 = 3.14 x (d/2)^2

1.1304 = 0.785d^2

d^2 = 1.1304/0.785

d^2 = 1.440

d = sqrt(1.440)

d ≈ 1.2

Therefore, the diameter of the circle is approximately 1.2 kilometers.

Find the maximum and the minimum value of the following objective function, and the value ofxandyat which they occur. the functionF=5y−4xsubject toy≤4x+1,y≥−4x+5, andx≤4The maximum value of the objective function is whenx=andy=

Answers

The maximum value of the objective function is 73 when x=4 and y=17 and minimum value  is 21 when x=1 and y=5.

To find the maximum and minimum values of the objective function F=5y−4x, we need to use the constraints given in the question and solve for x and y. The constraints are y≤4x+1, y≥−4x+5, and x≤4.

First, we need to graph the constraints to find the feasible region. The feasible region is the area on the graph where all the constraints are satisfied.

Next, we need to find the corner points of the feasible region. The corner points are where the constraints intersect. The corner points are (1, 5), (4, 17), and (4, 11).

Finally, we need to plug in the corner points into the objective function to find the maximum and minimum values.

F(1, 5) = 5(5) - 4(1) = 21
F(4, 17) = 5(17) - 4(4) = 73
F(4, 11) = 5(11) - 4(4) = 47

The maximum value of the objective function is 73 when x=4 and y=17. The minimum value of the objective function is 21 when x=1 and y=5.
