(A) The standard error of the estimate for the given regression equation is 3.04.

(B) The t-statistic for the given regression equation is 2.97, which is greater than the critical value at the 0.05 level of significance.

(A) The standard error of the estimate measures the variability of the observed data points around the regression line. It indicates how well the regression equation fits the data.

A lower value of standard error of the estimate indicates a better fit of the regression line to the data. In this case, the value of the standard error of the estimate is 3.04, which means that the observed data points are expected to deviate from the predicted values by approximately 3.04 units on average.

(B) To test for a significant relationship between the independent variable and dependent variable, we use the t-test. The t-test is used to determine whether the coefficient of the independent variable in the regression equation is significantly different from zero.

The t-statistic is calculated by dividing the estimated coefficient of the independent variable by its standard error. In this case, the t-statistic is 2.97, which is greater than the critical value at the 0.05 level of significance, indicating that the relationship between the independent variable and dependent variable is statistically significant. Therefore, we can conclude that the estimated regression equation provides a good fit to the data and there is a significant relationship between the independent variable and dependent variable.

Answer:

120

Step-by-step explanation:

The sum of the angles in a quadrilateral is 360 degrees

2t+t+2t+t = 360

6t = 360

Divide by 6

6t/6 = 360/6

t = 60

Angle Z = 2t

Angle Z = 2*60 = 120

Answer:

\(120 \: \: degrees\)

Second answer is correct.

Step-by-step explanation:

The sum of the angles in a qudrilateral = 360°

\(t + 2t + t + 2t = 360 \\ 6t = 360 \\ \frac{6t}{6} = \frac{360}{6} \\ t = 60\)

angle z

\(2t = 60 \times 2 \\ \: \: \: \: \: \: \: = 120\)

SET 1 will form triangle (√2 cm  , 9cm , √7cm )

Define right angle triangle?

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The sum of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

In a right-angled triangle, the hypotenuse is the longest side and

Hypotenuse² = Base² + Perpendicular²

Let  9cm  be the hypotenuse and √2ft  and √7cm to be the base and perpendicular respectively,

9 = √2)²+√7)²

9=9

Hence, set 1 is the correct set of side lengths for a right triangle.

What is Pythagoras theorem?

The right triangle's three sides are interconnected. The Pythagorean Theorem explains this connection. This theorem states that in a right triangle,

The applicants that would have to apply in order to meet the target is 52. Option 4 is correct.

We have to define x as the applications to meet target

The number of persons to hire is 30

10 percent do not meet requirements. Hence 90 meets the requirements. 90% of x

= 0.9X

12% fail the pre screening stage. Hence 88% have passed it. This would be 88% of 0.9x. = 0.792x

23% Did not come for the interview, hence 77% showed up. This would be 0.77*0.792x = 0.60984x

then 5% are said to have failed the background test. This means that 95% passed the test.

0.95 * 0.60984x = 0.579348X

We have to equate this to 30 in order to get the value of x

0.579348X = 30

divide through by 0.579348

X = 30 / 0.579348

The substitution, transforms the Bernoulli equation dy/dx + P(x)y = Q(x)y^n into the linear equation dv/dx+(1-n)P(x)v(x) = (1 - n)Q(x). It is done as:

The equation is in the form  

dy/dx +P(x)y=Q(x)yⁿ,  where P and Q are functions of x or constants, this is called Bernoulli's equation.

Now, we have to substitution using 

\(v = {y}^{1 - n} \)

Differentiating both side with respect to 'x'

\(v' = (1 - n) {y}^{ - n} y' \\ \frac{dx}{dy} = \frac{1}{1 - n} {y}^{n} v'\)

we get,

\(= \frac{1}{1 - n} {y}^{n} v' + p(x)y \\ = q(x) {y}^{n} \\ = v' + (1 - n)p(x) {y}^{1 - n} \\ = (1 - n)q(x)\)

Now, by using 

\(v' = {y}^{1 - n} \)

The given equation is expressed as:

\(v + (1 - n)p(x)v = (1 - n)q(x)\)

or dv/dx + (1-n)P(x)v(x) = (1 - n)Q(x)

The domain of the function \(g(x) = loga (x² - 9) is (-∞,-3) and (3, ∞)\).

A logarithmic function is the inverse of an exponential function, as we know.

The logarithmic function's basic definition is \(loga (x) = y\).

The logarithm of a number x to the base a is y.

Here, a is called the base of the logarithm.

It is written as \(y = loga(x)\).

Domain of the function:

For all x such that \(x² - 9 > 0\),

the function

\(g(x) = loga (x² - 9)\) exists.

g(x) is defined when

\(x² - 9\) is greater than zero.

Thus, for the function \(g(x) = loga (x² - 9)\),

the domain is given by all real numbers excluding -3 and 3.

This means that the domain is \((-∞,-3) and (3, ∞)\).

Answer: 171.3in^2

Step-by-step explanation: Each round part is 1/4 of a circle. First we get the radius of the circle which is 2. Then we find the area so it is 3.14 * 2^2  = 3.14 * 4. That is 12.56. Then, because it is 1/4 of a circle you do 1/4 * 12.56 which is 3.14. There are two of those round parts so 3.14 * 2 = 6.28. The square in between them is 2*2 = 4. Then we find the width which will be 25in - 2in = 23in. 23 * 7 = 161. 161 + 4 + 6.28 = 171.28. Then we round so it is 171.3.

The trader could sell 4 covered call contracts on half of her shares, covering a total of 400 shares (4 contracts * 100 shares per contract), leaving her with 452 shares remaining uncovered.

To determine the number of covered call contracts a trader could sell when owning 852 shares of a stock and planning to cover half of her shares, we need to consider that each standard covered call contract typically covers 100 shares of the underlying stock.

Since the trader plans to sell covered calls on half of her shares, we can calculate the number of shares she wants to cover as 852/2 = 426 shares.

To determine the number of covered call contracts, we divide the number of shares to be covered by the number of shares covered per contract:

Number of contracts = Number of shares to be covered / Number of shares covered per contract

                  = 426 shares / 100 shares per contract

                  = 4.26 contracts.

Since contracts are usually traded in whole numbers, the trader could sell 4 covered call contracts. However, it's important to note that fractional contracts are generally not available, so in practical terms, the trader would likely round down to the nearest whole number.

Answer:

Therefore, the two cities are 91.22 degrees apart in latitude and 212.05 degrees apart in longitude.

Step-by-step explanation:

The Haversine formula is:

d = 2r * arcsin(sqrt(sin^2((lat2 - lat1)/2) + cos(lat1) * cos(lat2) * sin^2((lon2 - lon1)/2)))

where:

d is the distance between the two points

r is the radius of the Earth (mean radius = 6,371km)

lat1 and lat2 are the latitude values of the two points

lon1 and lon2 are the longitude values of the two points

Using this formula, we can calculate the distance between Liverpool and Melbourne in terms of latitude and longitude:

Latitude difference = |53.41 - (-37.81)| = 91.22 degrees

Longitude difference = |(-2.99) - 144.96| = 147.95 degrees

Note that the longitude difference is greater than 180 degrees, which means that we need to account for the fact that the two cities are on opposite sides of the 180 degree meridian. To do this, we can subtract the longitude difference from 360 degrees:

Longitude difference = 360 - 147.95 = 212.05 degrees

Therefore, the two cities are 91.22 degrees apart in latitude and 212.05 degrees apart in longitude.
