Answer:

$63.00

Step-by-step explanation:

Since you have sales tax, you would do a 10% sales tax for 15 dollar

10/100 = x/15

Therefore you will calculate x and 100 divided by 15 which would be 6.6 repeated

You would round to the nearest tenth and get 6.6 then you would add 56.4 as in the tip+ month airtime usage and get 63 dollars.

The side of the triangle from shortest to longest can be arranged as,

A triangle is a polygon with three sides such that the sum of all the interior angles is always 180°.

In a triangle, the side opposite to the biggest angle is always the lengthiest, while the side opposite to the smallest angle is the shortest.
Given that the measure of ∠A is 100°, therefore, the length of the side BC will be the lengthiest.
Also, the measure of ∠B is 20°, therefore, the length of the side AC will be the shortest.

Hence, BC > AB > AC.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

The rate of change of the distance below the sea level with respect to time is 11 feet per second.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

The table has a linear relationship.

We can choose two data from the table.

At time = 15,

Distance below the sea level = 545 feet.

At time = 27,

Distance between the sea level = 677

Now,

The rate of change of the distance below the sea level with respect to time.

Slope:

Answer:

Here is a table showing the relationship between the number of coins collected and the total points earned:

Number of coins (c) Total points (p)

0 0

1 20

2 35

3 50

4 65

5 80

6 95

7 110

8 125

9 140

10 155

To graph these ordered pairs, we can plot the number of coins collected (c) on the x-axis and the total points earned (p) on the y-axis. Then we can plot each ordered pair as a point on the graph and connect the points with a line. The resulting graph should show a linear relationship between c and p, with a slope of 15 and a y-intercept of 0.

Analyzing the graph, we can see that as the number of coins collected increases, the total points earned also increases at a constant rate. This suggests that collecting coins is an important part of the game, as it significantly increases the player's total score. Additionally, the slope of the line (15) tells us that each additional coin collected is worth 15 points, while reaching the next level is worth only 5 points.

To calculate the angle between the transmission axes of the two polarizers, we need to use the equation for the intensity of transmitted light through two polarizers:

I = I0 * cos^2(θ)

Where:

I is the intensity of transmitted light,

I0 is the initial intensity of unpolarized light incident on the first polarizer,

θ is the angle between the transmission axes of the two polarizers.

Given:

I0 = 65 W/m^2 (initial intensity of unpolarized light)

A = (1.0 cm)^2 (area of the photodiode)

E = 10 mJ (energy absorbed by the photodiode)

t = 4.0 s (exposure time)

To calculate the intensity I, we can use the formula:

I = E / (A * t)

Plugging in the given values:

I = (10 mJ) / [(1.0 cm)^2 * 4.0 s]

  = (10 × 10^(-3)) / [(1.0 × 10^(-2))^2 * 4.0]

  = 2.5 × 10^(3) / 4.0

  = 625 W/m^2

Now, we can equate the transmitted intensity I to the initial intensity I0 * cos^2(θ):

625 = 65 * cos^2(θ)

Dividing both sides of the equation by 65:

cos^2(θ) = 625 / 65

cos^2(θ) = 9.615

Taking the square root of both sides to solve for cos(θ):

cos(θ) = √(9.615)

θ ≈ arccos(√9.615)

θ ≈ 27.6 degrees

Therefore, the angle between the transmission axes of the two polarizers is approximately 27.6 degrees.

Length = 14cm

Breadth ( AKA Width) = 9cm

Step-by-step explanation:

1) Address the facts

(L)Length = b + 5

(W)Width = b

(P)Perimeter = 46cm

= 2(b + 5 +b)

= 2(2b + 5) 2)Simplify the equation

3) Make b the SOTF (subject of the formula)

46 = 2(2b + 5)

46 = 4b + 10 3a) Simplify further

36 = 4b 3b) Minus 10 on both sides

9 = b

\____ 3c) Divide by 4 on both sides to get JUST b

4) Substitute aka replace the letters with numbers

L = b + 5

= 9 + 5

= 14cm

W = b = 9cm

Therefore the breadth(/width) is 9cm and the length is 14cm :)

Answer:

The condition of a ≠ 0 is imposed in the definition of the quadratic function to ensure that the function represents a true quadratic equation.

In a quadratic function of the form f(x) = ax^2 + bx + c, the coefficient "a" represents the leading coefficient or the coefficient of the quadratic term. This coefficient determines the shape of the graph and whether the function represents a quadratic equation.

When a = 0, the quadratic term becomes zero, resulting in a linear function (f(x) = bx + c) rather than a quadratic function. In other words, without the condition a ≠ 0, the function would degenerate into a straight line, losing the key characteristics and properties associated with quadratic equations, such as the presence of a vertex, concavity, and the ability to intersect the x-axis at most two times.

By imposing the condition a ≠ 0, we ensure that the quadratic function represents a genuine quadratic equation, allowing us to study and analyze its properties, such as the vertex, axis of symmetry, roots, and the behavior of the graph. It helps distinguish quadratic functions from linear functions and ensures that we are working with the appropriate mathematical model when dealing with quadratic relationships and phenomena.

You can do this problem in two ways.
Either the long way or the short and easy way.

Or you can do the slightly longer way which finds you the tax amount which then you can add onto the total:

You do 180*0.06 which gets you $10.80 of tax. $10.80 is how much tax they have to pay on top of the $180, then we can do 180+10.80 to get us the grand total of $190.80.

Step-by-step explanation:

When dividing two exponents, you can use a formula of:

\(\frac{x^a}{x^b} = x^{a - b}\)

So your question would return:

\(\frac{3^2}{3^6} = 3^{2-6} = 3^{-4}\)

When an exponent is negative, it is equal to 1 divided by the positive number, so for this question, it would be:

\(\frac{1}{3^4}\)

The first statement is true, while the second and third statements are false. Multicollinearity can impact the model and can lead to misleading results, even if some predictor variables are highly correlated with each other. Additionally, the significance of F-test alone cannot rule out the possibility of multicollinearity.

i. The first statement is true. The Variance Inflation Factor (VIF) can be used to measure the amount of collinearity in the model. VIF is a measure of the amount of correlation between a predictor variable and the other predictor variables in the model. Higher VIF values indicate higher levels of collinearity. Typically, a VIF value greater than 10 indicates a problematic level of collinearity.

ii. The second statement is false. If some predictor variables in the model are highly correlated with each other, it can lead to multicollinearity, which can impact the model's results. Multicollinearity can make it difficult to interpret the individual effect of each predictor variable on the outcome variable, and it can also increase the standard errors of the regression coefficients. This can result in reduced statistical power, decreased predictive accuracy, and misleading results.

iii. The third statement is also false. A significant F-test indicates that at least one of the predictor variables in the model is related to the outcome variable, but it does not rule out the possibility of multicollinearity. If none of the t-tests are significant, it could be due to a lack of statistical power or the presence of multicollinearity, which can make it difficult to detect the individual effects of each predictor variable.

To test for multicollinearity, one can examine the VIF values or use other diagnostic tests, such as the condition number or tolerance values. If multicollinearity is detected, one can consider removing one of the highly correlated predictor variables or using techniques like regularization to address it.

The z-score for the new player's salary is 0.59375

The z-score is a measure of how many standard deviations a value is from the mean. To find the z-score for a salary of $2.65 million, we can use the following formula:

z = (x - μ) / σ

where:

x = the salary of the new player ($2.65 million)

μ = the mean salary of professional baseball players ($2.46 million)

σ = the standard deviation of the salary ($0.32 million)

Plugging in the values, we get:

z = ($2.65 million - $2.46 million) / $0.32 million

z = ($0.19 million) / $0.32 million

z = 0.59375

Therefore, the z-score for the new player's salary is 0.59375. This means that the new player's salary is 0.59375 standard deviations above the mean salary of professional baseball players.
