Answer:

7.5

Step-by-step explanation:

given:

3/4 = x/10    (multiply both sides by 10)

(3/4)(10) = x

x = 30/4

x = 7.5

The value of x is 7.5

Given:

The proportion 3/4 = x/10

3/4 = x/10

30 = 4x

30/4 = x

7.5 = x

Therefore, the final answer is 7.5.

A significance test tells the researcher how likely it is that the results of the experiment occurred by chance alone. This is the correct option among the given options.

Significance testing is a statistical method used to determine whether a result or relationship in data is significant or not. It informs you whether there is sufficient evidence to reject the null hypothesis that there is no difference between two groups or no association between two variables.

The null hypothesis is always that there is no difference between the groups or no relationship between the variables. A significance test assesses how likely it is that the null hypothesis is true based on the sample data.

If the probability of getting such data is low, we reject the null hypothesis and accept the alternative hypothesis that there is a difference or an association between the variables.

Step-by-step explanation:

Therefore, the rate of the boat in still water is 70 mph, and the rate of the current is 30 mph.

Let's denote the rate of the boat in still water as "b" and the rate of the current as "c."

When the boat is traveling upstream, it is going against the current, so the effective speed is reduced. The speed of the boat relative to the ground can be calculated as (b - c).

Given that it takes 5 hours to travel 200 miles upstream, we can set up the equation:

Distance = Speed * Time

200 = (b - c) * 5

Dividing both sides by 5, we get:

40 = b - c (Equation 1)

When the boat is traveling downstream, it is aided by the current, so the effective speed is increased. The speed of the boat relative to the ground can be calculated as (b + c).

Given that it takes 2 hours to travel 200 miles downstream, we can set up the equation:

200 = (b + c) * 2

Dividing both sides by 2, we get:

100 = b + c (Equation 2)

Now we have a system of equations consisting of Equation 1 and Equation 2:

40 = b - c

100 = b + c

We can solve this system of equations using any method of solving simultaneous equations, such as substitution or elimination.

Adding Equation 1 and Equation 2:

40 + 100 = (b - c) + (b + c)

140 = 2b

Dividing both sides by 2, we get:

b = 70

Substituting the value of b back into Equation 1 or Equation 2:

40 = 70 - c

Subtracting 70 from both sides:

-30 = -c

Multiplying both sides by -1, we get:

30 = c

Answer:

u = 6/35

Step-by-step explanation:

w = k * u

w = ku

Where

k = constant of proportionality

if w=5 when u= 3

w = ku

5 = k * 3

5 = 3k

k = 5/3

find u when w is =2/7​

w = ku

2/7 = 5/3 * U

2/7 = 5/3u

u = 2/7 ÷ 5/3

= 2/7 × 3/5

= (2*3)/(7*5)

= 6/35

u = 6/35

Answer:

A. Right a multiple of 2 and up a multiple of 1.

B. (2, 1)

C. the same

Step-by-step explanation:

A. The original point was (2, 1), so if Larissa moves right a multiple of 2 and up a multiple of 1, she'll stay within the ratio.

B. We already know this is proportional, since it goes through the origin; the line just has to pass through the right point: (2,1)

C. The line will be proportional, so as long x is twice as much as y, Larissa will have the same shade of green paint every time.

The situation that could be true about the reduction in Julie's net worth will be; d). Julie's assets decreased by more than her liabilities.

'Net Worth' is characterized as 'the value of all the assets one possesses after subtracting all his/her debts or liabilities.'

In the given situation, the decrease in Julie's net worth would denote that the total of her liabilities for that financial year exceeded her total assets given in the question.

However another possibility could be that the decrease faced in her liabilities is higher than the decrease in her assets leading her net worth to be negative.

The main answer to your question is "interchanging". To find the inverse of a function, we interchange the numbers in each ordered pair of the function. This means that we switch the x and y values of each point in the function.

For example, if we have a function f(x) = 2x + 3, the ordered pairs would be (1,5), (2,7), (3,9), etc. To find the inverse function, we would switch the x and y values of each point to get ordered pairs such as (5,1), (7,2), (9,3), etc.

The explanation for why we interchange the numbers is that the inverse function "undoes" the original function. If we apply the original function to a number, the inverse function will take us back to the original number. By switching the x and y values, we make sure that the inverse function will undo the original function.

In conclusion, to find the inverse of a function, we interchange the numbers in each ordered pair of the function. This ensures that the inverse function will undo the original function.
Hi! I'm happy to help you with your question.

Main answer: The inverse of a function can be found by interchanging the numbers in each ordered pair of the function.

Explanation: When finding the inverse of a function, you are essentially swapping the input and output values in each ordered pair (x, y) to create a new ordered pair (y, x). This process is called interchanging the numbers in the ordered pair.

Conclusion: To find the inverse of a function, you need to interchange the numbers in each ordered pair of the function, which essentially swaps the input and output values.

x=9

Answer:

16. \(x = 80^\circ\)

17. \(x = 55, y =70, z = 55\)

18. \(x =8, y =3\)

19. \(r = 66^\circ\), \(t = 73^\circ\)

20. \(y = 70^\circ, x = 55^\circ\)

21. \(x =56^\circ, y = 62^\circ\)

Step-by-step explanation:

16. Side \(AB = AC\)

So, the opposite angles of the triangle will also be equal.

\(\angle B =\angle C = 50^\circ\)

Using triangle sum property, angle of all the internal angles of a triangle is equal to \(180^\circ\).

\(50+50+x = 180\\\Rightarrow x = \bold{80^\circ}\)

17. Two sides are given as equal, \(x = z\)

Angles on a straight line are always equal to \(180^\circ\).

So,

\(x + 125 = 180\\\Rightarrow x = 55\)

\(z = 55\)

Using triangle sum property, angle of all the internal angles of a triangle is equal to \(180^\circ\).

\(55+55+y = 180\\\Rightarrow y = \bold{70^\circ}\)

18. All the angles are given equal to each other, therefore all the sides of the triangle will also be equal to each other.

\(4x+7 = 13y =39\)

\(13y = 39\\\Rightarrow y = 3\)

\(4x +7 = 39\\\Rightarrow 4x = 32\\\Rightarrow x = 8\)

19. Two sides are given equal to each other, therefore angles opposite to them will be equal.

Using the triangle sum property in the left triangle:

\(r + 57 + 57 = 180\\\Rightarrow r = 66^\circ\)

Using the property that vertically opposite angles are equal and the triangle sum property in the right triangle.

\(t+50+57 = 180 \\\Rightarrow t = 73^\circ\)

20. All the sides are given equal to each other.

So, all the angles will be equal to \(60^\circ\).

\(y - 10 = 60\\\Rightarrow y = 70^\circ\)

\(x+5=60\\\Rightarrow x = 55^\circ\)

21. Angles on a straight line are always equal to \(180^\circ\).

Angles opposite to equal sides in a triangle are also equal.

\(118 + y = 180\\\Rightarrow y = 62^\circ\)

Using triangle sum property:

\(x+2y = 180\\\Rightarrow x = 180 - 124 = \bold{56^\circ}\)

Answer:

Area of the shaded region = (8x + 6)

Step-by-step explanation:

Area of the shaded region = Area of the large rectangle - Area of the smaller rectangle

Area of the large rectangle = Length × width

                                             = (x + 3)(x + 2)

                                             = x(x + 2) + 3(x + 2)

                                             = x² + 2x + 3x + 6

                                             = x² + 5x + 6

Area of the smaller rectangle = x(x - 3)

                                                 = (x² - 3x)

Area of the shaded region = (x² + 5x + 6) - (x² - 3x)

                                            = x² + 5x + 6 - x² + 3x

                                            = (8x + 6)
