The coefficient of elasticity of demand would be equal to 2 .

The price elasticity of demand for a good determines how responsive the desired amount is to the price (PED).

We know that the coefficient of elasticity of demand is given by

ED = Change in demand(percent) ÷ change in price (percent)

ED = 20% ÷ 10% = 2

ANSERS

(a) The function is:

(b) At the end of one year, he would have paid $2,380.

Answer:

The equation of the linear function represented in the table is y = -4x + 1.

Explanation:

Since the values in the x-variable are consecutive, let's take a look at the y-values.

Let's determine the common difference of the y-values.

As we can see, the common difference between the y-values is -4. Therefore, the slope of the equation is -4.

To determine the y-intercept, let's subtract -4 from -3 to determine the y-value at x = 0.

Hence, the y-intercept is 1.

Therefore, the equation is y = -4x + 1.

The sum of the angles on a straight line is 180 degrees. This means that

angle MJO + angle NJO = 180

From the information given,

angle MJO = 131

angle NJO = 15x + 4

Thus,

131 + 15x + 4 = 180

135 + 15x = 180

15x = 180 - 135 = 45

x = 45/15

x = 3

We would substitute x = 3 into angle NJO = 15x + 4

angle NJO = 15 * 3 + 4 = 45 + 4

angle NJO = 49

We will see that there are 19,656,000 different passwords that can be made with the given characters.

We need to find the number of possible options for each character of the password.

The first character is a letter, so we have 26 options.

The second character is another letter, so we have 25 options (because we can't repeat).

Then we have 5 digits, for each digit we have 10 options (removing one for each subsequent one)

The total number of passwords is given by the product between the numbers of options.

P = 26*25*10*9*8*7*6 = 19,656,000

3. The correct tangent statement is;

Here's a diagram to show why

The two lines never intersect (are parallel lines) thus the equation:

6 - x = 3 - x

Has no solutions.

Here we have the equation:

6 - x = 3 - x

And (supposedly) a graph of the two lines:

y = 6 - x

y = 3 - x

Notice that the part on the linear equations that depens of x is equal to the ones in the equation above.

So basically we have a system of equations:

y = 6 - x

y = 3 - x

Because "y" is the same thing in both equations, we can rewrite:

6 - x = y = 3 - x

If we remove the part in the middle, we return to the original equation:

6 - x = 3 - x

Now, the solution of that equation is given by the point where the two graphs of the linear equations intersect, it will never happen, because both linear equations are parallel (have the same slope) which means that the equation:

6 - x = 3 - x

Has no solutions.

The probability that the aircraft is overloaded is 97.98%, which means the pilot should take the action.

In a Normal distribution with mean ц and standard deviation σ, the z-score of a measure x is given by:

Z = X-ц / σ

· It measures how many standard deviations the measure is from the mean.

· After finding Z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

· By the Central Limit Theorem, the sampling distribution of sample means of the size n has standard deviation σ

σ = σ / [tex]\sqrt{n}[/tex]    

σ is standard deviation

n is the sample size.

Given that the mean and the standard deviation of the population is 176.1 lb and 35.4 respectively.

⇒ ц = 176.1  and σ = 35.4

For a sample of 43 passengers, we have

n = 43

σ =  [tex]\frac{35.4}{\sqrt{43}}[/tex]

σ = 5.398

Z = X-ц / σ

Z = [tex]\frac{165-176.1}{5.398}[/tex]

Z = -2.05 has p- value of 0.9798

The probability that the aircraft is loaded is

1 - p-value of Z

1 - 0.0202 = 0.9798

The probability that the aircraft is overloaded is 97.98%

Step-by-step explanation:

Supposing that the two points are (2,4) and (10,10), the distance between them is given by:

A. 10.

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

This formula is derived from the Pythagorean Theorem, as the points form a right triangle in the xy-plane, with the hypotenuse being the distance between them.

For this problem, the two points are (2,4) and (10,10), hence the distance between them is given as follows:

[tex]D = \sqrt{(10 - 2)^2+(10 - 4)^2} = \sqrt{100} = 10[/tex]

Hence the distance is of 10 units and option A is correct.
