Flying against the wind, an airplane travels 6230 kilometers in 7 hours. flying with the wind, the same plane travels 10,480 kilometers in 8 hours. what is the rate of the plane in still air and what is the rate of the wind?

Answers

The speed (rate) of the plane in still air is 1100 kilometers per hour and the speed (rate) of the wind is 210 kilometers per hour.

We assume the speed (rate) of the plane in still air to be x kilometers per hour, and the speed (rate) of the wind to be y kilometers per hour.

Thus, flying against the wind, the acting speed (rate) for the plane will be x - y kilometers per hour.

Flying with the wind, the acting speed (rate) for the plane will be x + y kilometers per hour.

We are given that flying against the wind, the airplane travels 6230 kilometers in 7 hours.

Thus, speed (rate) = 6230/7 kilometers per hour = 890 kilometers per hour.

Equating this to the derived speed of the airplane flying against the wind, we get x - y = 890 ... (i).

We are given that flying with the wind, the airplane travels 10480 kilometers in 8 hours.

Thus, speed (rate) = 10480/8 kilometers per hour = 1310 kilometers per hour.

Equating this to the derived speed of the airplane flying with the wind, we get x + y = 1310  ... (i).

Now, on adding equations (i) and (ii), we get:

2x = 2200,

or, x = 1100.

Substituting x = 1100 in (ii), we get:

x + y = 1310,

or, 1100 + y = 1310,

or, y = 1310 - 1100 = 210.

Thus, the speed (rate) of the plane in still air is 1100 kilometers per hour and the speed (rate) of the wind is 210 kilometers per hour.

every subscription that she sells. Sophie gets $3 per subscription sold, in addition to a base
wage of $4 per hour. If they each sell a certain number of subscriptions in an hour, they will
end up earning the same amount. How much would each one earn?
Write a system of equations, graph them, and type the solution.

Answers

Answer:

The each have to place 2 subscriptions

Step-by-step explanation:

Adriana

E (earnings) = 6 + 2*x where x is the number of subscriptions

Sophie

E (earnings) = 4 + 3x

For them to earn the same amount, their right sides must be equated.

4 + 3x = 6  + 2x                    Subtract 2x from both sides

4 + 3x - 2x = 6+ 2x  - 2x       Combine

4 + x = 6                                Subtract 4 from both sides

4 - 4 + x = 6 - 4

The purpose of statistical inference is to make estimates or draw conclusions about a _____. a. population based upon information obtained from the sample b. mean of the sample based upon the mean of the population c. sample based upon information obtained from the population d. statistic based upon information obtained from the population

Answers

a)The purpose of statistical inference is to make estimates or draw conclusions about a population based upon information obtained from the sample.

Statistical inference is the process of drawing conclusions about populations or scientific truths from data. There are many ways to make inferences, including statistical modeling, data-driven strategies, and the explicit use of designs and randomization in analyses.

Hypothesis testing is a form of statistical inference that uses data from a sample to draw conclusions about a population parameter or population probability distribution.

First, a preliminary assumption is made about the parameter or distribution. This assumption is called the null hypothesis and is denoted H0.

An alternative hypothesis (denoted Ha) is then defined, which is the opposite of what is stated in the null hypothesis. The hypothesis testing procedure involves using sample data to determine whether or not H0 can be rejected. If H0 is rejected, the statistical conclusion is that the alternative hypothesis Ha is true.

Answers

The correct answer is option B which is we need ∠L ≅ ∠R to prove congruency.

What is congruency?

The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.

According to the SAS theorem which means Side Angle Side, The angle which is included between the two sides must be congruent.

Here we are given that

Suppose that x and y vary inversely, and x = 12 when y = 8 . Write the function that models the inverse variation.

Answer:

[tex]y=\frac{96}{x}[/tex]

Step-by-step explanation:

So when x and y, vary inversely, it means that the product of x and y will remain constant such that: [tex]xy=c[/tex]. This means that the function can be defined as [tex]y=\frac{c}{x}[/tex] by dividing both sides by x. In this case x=12, and y=8, this means the constant is equal to 12 * 8 which is 96. So we have the equation:  [tex]xy = 96[/tex], which can be defined as [tex]y=\frac{96}{x}[/tex]

1) The dimensions of an irregular solid are as shown in the figure below.

a) Write a polynomial function, in standard form, to model the volume of this solid.

b) If the volume of the solid is 208 cubic inches, what is the value of x?

Answers

Hello,

a) Volume of the figure = Volume of light blue rectangular parallelepiped - volume of dark blue rectangular parallelepiped

Volume of rectangular parallelepiped = lengh × high × height

Volume of light blue rectangular parallelepiped :

V = (x + 2) × (x + 5) × (2x + 1)

V = (x² + 5x + 2x + 10) × (2x + 1)

V = (x² + 7x + 10) × (2x + 1)

V = 2x³ + 15x² + 27x + 10

Volume of dark blue rectangular parallelepiped :

V = x × 3 × (x + 5)

V = 3x(x + 5)

V = 3x² + 15x

Polynomial function, in standard form, to model the volume of this solid :

V = 2x³ + 15x² + 27x + 10 - (3x² + 15x)

V = 2x³ + 15x² - 3x² + 27x - 15x + 10

V = 2x³ + 12x² + 12x + 10

b) We have to solve 2x³ + 12x² + 12x + 10 = 208

⇔ 2x³ + 12x² + 12x - 198 = 0

⇔ 2(x - 3)(x² + 9x + 33) = 0

⇔ x = 3 or x² + 9x + 33 = 0

a = 1 ; b = 9 ; c = 33

Δ = b² - 4ac = 9² - 4 × 1 × 33 = -51 < 0 ⇔ Δ < 0 ⇒ no solution

So if the volume of the solid is 208 cubic inches, the value of x is 3

Circle Q is centered at the origin. Is point (-5, 0) on the circle? Justify your answer

Answers

The answer is No, because the distance from the origin to point (-5,0) is less than the radius of the circle. Why? Well, given that point (-5,0) is 5 units away in absolute value from the origin, we can justify that it is not on the circle because the radius is 6 units long.

How to find the radius of a circle:

To find the radius of a circle, what we do typically is we start at the middle point of the circle (which in this case is the origin or (0,0)). From the middle point, we measure the distance to one side of the circle. This side of the circle can be either vertical or horizontal, but you mainly will encounter problems where it is horizontal. Because we have a number line, we can count out that the distance from the origin to any of the sides of the circle is 6 units. Because 6 is greater than 5, we now know that the point (-5,0) is not on the circle.

The scatter plot shows the number of strawberries that have been picked on the farm during the month of February:


A scatter plot with points showing an upward trend with points that are moderately spread out from a line of best fit. The y axis is labeled Number of Strawberries and the x axis is labeled Days in February


Part A: Using computer software, a correlation coefficient of r = 0.01 was calculated. Based on the scatter plot, is that an accurate value for this data? Why or why not? (5 points)


Part B: Instead of comparing the number of strawberries picked and the day in February, write a scenario that would be a causal relationship for strawberries picked on the farm. (5

Answers

It's not an accurate value for the data based on the scatter plot, r = 0.01 is not an accurate value for this data, because 0.01 means practically no correlation, while the points on the graph are moderately correlated

How to illustrate the information?

1. Part A:

Since the points in the scatter plot shows a moderated upward trend, you must expect a correlation coefficient close to ± 0.5. A correlation coefficient of 0.01 is too close to 0, which would mean that the points are almost not correlated at all.

The correlation coefficients, r, measure the strength of the correlation of two variables and they can have values from - 1 to  1.

Here, r = - 1 is a perfect negative correlation as the points will adjust perfectly to a line with a negative slope.

r =  + 1 is a perfect positive correlation: the points will adjust perfectly to a line with a positive slope.

r = 0 means that the variables are not correlated at all.

Hence, the closer to zero, the worse the correlation is, and that is what r = 0.01 means, but the graph shows another thing.

Therefore, the calculated value of r = 0.01 is not accurate for this scatter plot.

2. Part B.

A causal relationship means that the explanatory variable (the independent variable) is the cause of the dependent variable.

Hence, you must find a reasonable variable that can be the cause of the number of strawberries picked.

Thus, the scenario could be:

Amount of rainfall in mm (x)         Number of strawberries picked (y)

      100                                                     20

        50                                                     40

        25                                                     80

        12.5                                                  160

        6.25                                                 320

The amount of rainfall is the cause of the number of strawberries picked, and you could find a model that relates both variables.

d. For the group(s) with similar triangles, tell (roughly) what transformations would be needed to make one of the triangles carry onto the other triangle in its group.

Answers

The two triangles in group A are similar because two angles of one are congruent to two angles of the other.

How to explain the triangle?

The two triangles in group A are similar because two angles of one are congruent to two angles of the other.

The two triangles in group B are not similar. The ratio of the short sides of the two triangles is 10:4 or 2.5:1, and that is the same ratio as the two sides 24 and 9.6.

However, using the fact that an angle bisector in a triangle divides the opposite side into two segments in the same ratio as the lengths of the two sides that include the angle, the length of the third side of the left triangle can be found to be about 25.12; and 9.25 times 2.5 is not close to 25.12.

b. In group A, the third side of the first triangle, by the Pythagorean Theorem, is sqrt(306).

The scale factor between the two triangles is 3:5, so the length of the third side of the second triangle is 15*(5/3) = 25.

In both triangles, the third angle measure is 31 degrees, since the sum of the three angles is 180.

c. The scale factor, again, is 3:5 which means the ratio of the areas of the two triangles is 3²:5² or 9:25.

d. The first triangle can be carried onto the second with the following transformations:

(1) dilate by a factor of 5/3 to make it the same size;

(2) rotate 90 degrees counterclockwise;

(3) translate so the hypotenuses of the two triangles are the same line segment; and

(4) reflect on the hypotenuse.

Let the frequency of the higher note be represented by f, and that of the lower note by [tex]f_{l}[/tex]. Thus, we have;

[tex]f_{l}[/tex] = [tex]\frac{2}{3}[/tex] f

Therefore, the expression for the frequency of the lower notes is   [tex]\frac{2}{3}[/tex] f.

The statement "The value of a is positive, so the vertex is a minimum" is correct.

What is a quadratic function?

Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

From the table we can find the quadratic function:

f(x) = ax² + bx + c

Plug (x, y) on the above function.

a + b + c = 3 ...(1)

9a + 3b + c = -3 ...(2)

25a + 5b + c = -5 ...(3)

After solving the above equations:

a = 0.5

b = -5

c = 7.5

The value of a is positive.

Thus, the statement "The value of a is positive, so the vertex is a minimum" is correct.
