Can Someone Explain How You Do This And Not Only Give Me The Answer So I Could Know The Formula?

Answers

Answer 1

Answer: 9/7 or 1 2/7

Step-by-step explanation:

Multiply 4 by the denominator and add 1:

29/7

Multiply 2 by seven (denominator) and add 6:

20/7

29/7 - 20/7 = 9/7

9/7 = 1 2/7

7 fits one time into nine and 2 is left.

The length of a rectangle is

Answers

Answer:

5 meters

Step-by-step explanation:

We should derive an equation to solve this problem.

Let's assign x to width and y to length.

[tex]2x-4=y[/tex]

and

[tex]2x+2y=22[/tex]

so

[tex]2x+2(2x-4)=22[/tex]

[tex]2x+4x-8=22[/tex]

[tex]6x-8=22[/tex]

[tex]6x=30[/tex]

How do you do the inverse of this function?

Answers

9514 1404 393

Answer:

  f^-1(x) = <see attachment>

Step-by-step explanation:

If we write the function as ...

  f(x) = ∛x +101/128x

Then the inverse function is the value of y when ...

  x = f(y)

This resolves to a cubic in y, whose solution can be found by use of any of the various cubic solution formulas. You can find the cubic by ...

  x = ∛y +by . . . . . . where b = 101/128

  x -by = ∛y . . . . . . . subtract by

  (x -by)³= y . . . . . . cube both sides

If we subtract the left side and expand the cube, we get ...

  b³y³ -3b²xy² +(1 +3bx²)y -x³ = 0 . . . . . . . a cubic in y

There will be one real and two complex solutions to this cubic. The real solution can be written in the form shown in the attachment. That is, ...

  y = f⁻¹(x) = [attachment expression]

A graph of it is shown in the second attachment. It is the reflection of f(x) across the line y = x, as an inverse function should be.

Additional comment

The idea here is to show that it is possible to write an expression for the inverse function. It is not pretty, and it is somewhat tedious to evaluate.

Which ordered pairs is a solution to −5x + 3y > 12?
(3, 9)


(-5, 5)


(3, -6)


(-2, -5)


(2, 8)


(-6, 0)

Answers

Answer :-

Given inequality ,

-5x +3y > 12 3y > 5x + 12 y > 5/3x + 12/3y > 5/3x + 4

From the options ,

When x is 3 and y = 9

y >1* 5 + 4y > 5 +4 9> 9 ( Not possible )

When x is -5 y is 5

y > 5/3*-5 + 4y > -8.3 + 4 5 > -3.7 ( Possible )

When x is 3 y is -6

y > 5 + 4 -6 > 9 ( Not possible )

When x is -2 y is -5

y > -3.33 + 4 -5 > -0.67 ( Possible )

When x is 2 y is 8

y > 3.33 + 4 8 > 7.77 ( possible )

When x is -6 y is 0

y > -10 +4 0 > -6 ( possible )
Given the inequality statement, -5x + 3y > 12

We’ll substitute the given points to determine which is a solution that satisfies the inequality:

(3, 9):
-5(3) + 3(9) > 12
-15 + 27 > 12
12 > 12 (False statement, as 12 ≯ 12)


(-5, 5):

-5x + 3y > 12

-5(-5) + 3(5) > 12

25 + 15 > 12

40 > 12 (True statement). Thus, it is a solution.


(3, -6)
-5(3) + 3(-6) > 12
-15 - 18 > 12
-33 > 12 (False statement. -33 ≯ 12).


(-2, -5)
-5(-2) + 3(-5) > 12
10 - 15 > 12
-5 > 12 (False statement. -5 ≯ 12).

Therefore, the only solution is (-5, 5).

Unit Rates
Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.

Answer the following questions about Kiley’s trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that Kiley is at rest (that is, not moving).

In this task, you will write the ratio of miles to hours for each leg of Kiley’s trip. You will then, express the ratio as a decimal number. Next, you will find the unit rate in miles per hour (mph) for each leg of the trip. If your unit rate includes a repeating decimal number, you must indicate which digits repeat (for example, write when the 3 repeats.) A description of each leg is listed below in parts A through F.

Part A
the car ride from Kiley’s house to the airport

Part B
at the airport, the walk from the car to the waiting area by the gate

Part C
the leg from the waiting area to the airplane’s takeoff

Part D
the airplane ride

Part E

Answer:

Step-by-step explanation:

When it says about hitting the ground, it means it hits the t-axis.

That means we have to solve for t-intercepts to find the solution.

Finding t-intercept, let y = 0.

[tex] \displaystyle \large{0 = - 16 {t}^{2} + 96t + 3}[/tex]

Use the Quadratic Formula.

[tex] \displaystyle \large{t = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} }[/tex]

Substitute in a = -16, b = 96 and c = 3.

[tex] \displaystyle \large{t = \frac{ - 96 \pm \sqrt{ {96}^{2} - 4( - 16)(3)} }{2( - 16)} } \\ \displaystyle \large{t = \frac{ - 96 \pm \sqrt{ 9216 + 192} }{ - 32} } \\ \displaystyle \large{t = \frac{ - 96 \pm \sqrt{ 9408} }{ - 32} } \\ \displaystyle \large{t = \frac{ - 96 \pm 56 \sqrt{3} }{ - 32} } \\ [/tex]

Then simplify to simplest form.

[tex] \displaystyle \large{t = \frac{ - 96 \pm 56 \sqrt{3} }{ - 32} } \\ \displaystyle \large{t = \frac{ 12\pm 7\sqrt{3} }{ 4} } \\ [/tex]

Then use the highest value/root which is 12+7√3 over 4 then input it in a calculator and you will see that the highest root is close to 6.

We use the highest root because thats when y or height = 0 hence if height = 0 then the object finally hits the ground.

You flip a coin 10 times and you get 10 heads. Based on these 10 outcomes what is
the empirical probability of getting a head?

Answers

The empirical probability is the ratio of the number of times an event occurred to the total number of trials. Hence, the empirical probability is 1.

The empirical probability is defined thus :

Number of times event occurred / total number of outcomes

Hence, the empirical probability of head in the experiment :

Number of heads / total number of tosses

P(Head) = 10/10 = 1

Therefore, the empirical probability of getting a head is 1.

A certain town is clustered around the town's largest employer, a paper mill. A researcher notices a large number of children with asthma and suspects the proportion of children with asthma in this town may be larger than the nationwide proportion of 7%.
(a) (2 pts) Write the null and alternative hypotheses.
(b) (3 pts) Suppose the researcher committed a Type I error. What did the researcher conclude and what was the reality regarding children with asthma?
(c) (3 pts) Suppose the researcher committed a Type II error instead. What did the researcher conclude and what was the reality regarding children with asthma?

Answers

Using statistical concepts, it is found that:

a)

The null hypothesis is: [tex]H_0: p \leq 0.07[/tex]

The alternative hypothesis is: [tex]H_0: p > 0.07[/tex]

b)

The type I error means that the researcher concluded that the proportion in this town was above 7%, while in reality it wasn't.

c)

The type II error means that the researcher concluded that the proportion in this town was not above 7%, while in reality it was.

Item a:

At the null hypothesis, we test if the proportion is the nationwide proportion of 7% of less, thus:

[tex]H_0: p \leq 0.07[/tex]

At the alternative hypothesis, we test if the proportion is larger than the nationwide proportion, that is:

[tex]H_1: p > 0.07[/tex]

Item b:

A Type I error happens when a true null hypothesis is rejected.

Thus, the type I error means that the researcher concluded that the proportion in this town was above 7%, while in reality it wasn't.

Item c:

A Type II error happens when a false null hypothesis is not-rejected.

Thus, the type II error means that the researcher concluded that the proportion in this town was not above 7%, while in reality it was.
