The test is proved that hypothesis that the population mean is atleast 3-miles per gallon.

A hypothesis is the proposed explanation for any kind of  phenomenon.

So here are the values of X  BAR i=2.4. S is 1.8.

Our sample n =100.

The null hypothesis here is that mu is greater than or equal to 3.

Against the alternative hypothesis that  is less than three. Now the calculated value for the test statistic is going to be the  equal to X bar is in (-)  knots. That's 2.4 -3. divided by S over  2^2 of end. So 1.8 divided by the square root of the  100 gives us negative 3.33. So we can refer to that box of the T distribution and we are  get the value. The p value for the test is going to be less than 0.5. Therefore we have the  strong evidence that the not hypothesis is going to be the  read checked it.  So  therefore we can reject to the  null hypothesis and then it can accept the alternative by the  hypothesis that  is less than three.

What are the denominator and numerator?

A fraction's top digit is always referred to as the numerator. It displays the number of our parts. A fraction's numerator—the lowest digit—is referred to as the denominator. It displays the overall number of pieces that something can be broken down into.

We have,

- 3/8 - 1/4

so, calculating the given values,

((-3) ÷ (8)) - (1 ÷ 4)

make the denominator the same by multiplying 1/4 by 2, we get,

An experiment involves selecting a random sample of 256 middle managers for study. one item of interest is their annual incomes. the sample mean is computed to be $35,420.00. if the population standard deviation is $2,050.00, the standard error of the mean is $128.125

The population mean's likelihood to differ from a sample mean is indicated by the standard error of the mean, or simply standard error. It reveals how much the sample mean would change if a study were to be repeated with fresh samples drawn from a single population.

By dividing the standard deviation by the square root of the sample size, the standard error is determined. By taking into account the sample-to-sample variability of the sample means, it provides the precision of a sample mean.

Standard error of the mean = 2050/sqrt {256} = $128.125

Using the given angles, the value of x in the triangle is x = 3

From the question, we are to determine the value of x

Given that the measures are the angles of a triangle ABC.

Then, we can write that

A + B + C = 180° (Sum of angles in a triangle)

From the given information,

A = 75

B = 2 + 11x

C = 70

Thus,

75 + 2 + 11x + 70 = 180

147 + 11x = 180

11x = 180 - 147

11x = 33

Divide both sides by 11

11x/11 = 33/11

x = 3

Hence, the value of x is 3

3. Subtraction property of equality

4. Definition of congruence

The given results can be proved by the linear pair property of angles on a straight lines.

The linear pair property can be defined as the sum of all the angles on the one side of a straight line is equal to 180°.

In the given diagram the following data is given,

The angles ∠DEH and ∠DEF are on the straight line HEF.

And, the angles ∠DEF and ∠FEG are on the straight line DEG.

As per the linear property of angles, it can be written as,

m∠DEH + m∠DEF = 180°.

And,  m∠DEF + m∠FEG = 180°.

Which implies that m∠DEH + m∠DEF = m∠DEF + m∠FEG

Subtract the common terms from both sides to get,

m∠DEH + m∠DEF - m∠DEF = m∠DEF + m∠FEG - m∠DEF

⇒ m∠DEH = m∠FEG

⇒ ∠DEH ≅ ∠FEG

This is also known as the property of vertically opposite angles.

The plane with an angle of depression of 70° is closer to the airport.

The distance between the plane and the airport is 15957 feet.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

Two planes are flying at an altitude of 15,000 feet.

The angle of depression from one plane to the airport is 70°.

This means,

The distance of the plane from the airport.

Sin 70 = 15,000 / Distance

Distance = 15,000/ sin 70 = 15,000 / 0.94 = 15957 feet _____(1)

The angle of depression from one plane to the airport is 60°.

The distance of the plane from the airport.

Sin 60 = 15,000 / Distance

Distance = 15,000/ sin 60 = 15,000 / 0.87 = 17241 feet _____(2)

3x + y = 4

Step-by-step explanation:

The standard form of an equation can be written as: ax + by = c

The equation is currently written in slope-intercept form.

In order to turn it into standard form, we must have both x and y on one side of the equation. So...

y = -3x + 4 Add 3x to both sides

3x + y = 4

Therefore the standard form of the equation y = -3x + 4 is 3x + y = 4

Three  pairs of fractions that have a sum of 5/6 are;

1/3 + 2/3 = 5/6

1/4 + 3/4 = 5/6

2/6 + 3/6 = 5/6

1/3 + 2/3 = 5/6: The fractions have a common bottom number of 3 because they both have the same bottom number.

Adding the top numbers: 1 plus 2 equals 3.

The total is three divided by three, which can also be written as one.

However, we need to show the total with a bottom number of 6 to match the original part. So, we make the top and bottom numbers twice as big to get 2/6. Hence , 1/3 + 2/3 = 2/6.

1/4 + 3/4 = 5/6:The fractions have the same bottom number, so their common denominator is 4.

When you add 1 and 3 together, you get 4.

The sum is four over four, and when simplified, it equals one.

Once again, we have to find a way to write the sum with a bottom number of 6 so that it is the same as the first number in the fraction. So, we take the top number and the bottom number and multiply them both by 3 to get the fraction 3/6. Hence, 1/4 + 3/4 = 3/6.

2/6 + 3/6 = 5/6:In this situation, the fractions already have the same bottom number which is 6.

Adding the top numbers together: 2 + 3 = 5.

The answer is 5/6, which is what we wanted to get.

Therefore each pair shows a different way to add numbers together, either by finding a number that both denominators can divide evenly into or by using numbers that already work well together.

Answer:

Step-by-step explanation:

There a few ways to solve this system. Since each equation is set equal to y on the left side, that means that we can set the right side of each equation to be equal to each other. So,

3x - 4 = -2x + 6

This can now be solved for x:

5x - 4 = 6 (added 2x to each side)

5x = 10 (added 4 to each side)

x = 2 (divided each side by 5)

Now that we know what x must be, we can plug 5 in for x in either of the equations and solve for y:

y = 3(5) - 4

y = 6 -4

y=2

This means y should be 2. To make sure this answer is correct, we can plug our y and x numbers into the OTHER equation to see if it makes sense:

(2) = -2(2) + 6

2 = -4 + 6

2=2

That looks right, so x = 2 and y = 2

A standard deviation (or σ) is a tool to measure how dispersed the data is in relation to the mean. While, in statistics, a central tendency is a central or typical value for a probability distribution. Some of the most common measures of central tendency consist of the arithmetic mean, the median, and the mode. Deviation means a change or a distance. But change is always followed by the word 'from'. Hence standard deviation is a measure of change or the distance from a measure of central tendency- which is normally the mean. Hence, standard deviation is different from a measure of central tendency.

Length of the curve is e² - 1 .

What is function?

In arithmetic, a function from a group X to a group Y assigns to every part of X precisely one part of Y. The set X is termed the domain of the function and therefore the set Y is termed the codomain of the function

Main body:

A parametric curve is a function expressed in components form, such that

x=f(t) , y=g(t). The length of a parametric curve on the interval a ≤ t ≤ b is given by the definite integral :

L =  [tex]\int\limits^a_b {\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt} )^2} } \, dt[/tex]

Let's begin by getting the first derivative of the components of the function with respect to the variable t.

x = e^t - t  

dx / dt = e^t−1

y = 4 e^t/2

dy /dt = 2 e^t/2

Substitute the derivatives into the following definite integral which computes the length of the parametric curve on the interval

[a,b]=[0,2].

L =[tex]\int\limits^a_b {\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt} )^2} } \, dt[/tex]

L=  [tex]\int\limits^2_0 {\sqrt{(e^{t}-1 )^2 + (2e^{t/2} } )^2} } \, dt[/tex]

L =[tex]\int\limits^2_0 {e^{t} -1} \, dt[/tex]

Evaluate the solution at the limits of integration to get the length.

L = (e² - 1 )- (e⁰ - 1)

L = e² - 1 - 1 + 1

L= e² - 1

Hence , length of the curve is e² - 1 .
