Rosie wanted to calculate the change in temperature today. When she woke up this morning, she recorded the temperature at -10^ F. When she went to bed that night, she recorded the temperature at 8^\F. What was the change in temperature from morning to night?

The angle created by the two rays or arms at a shared vertex is known as the angle measure in geometry.

With a protractor, you can determine how large an angle is. Alternatively, the congruent angles could be indicated on the figure by an arc. Supplementary angles are two angles whose combined measurements are 180°, such as two right angles since 90° + 90° Equals 180°. the measurement of an angle wherein 1 degree equals 1/360 of a circle.

An angle (created by perpendicular lines) that is exactly 90 degrees is called a right angle. Less than 90 degrees is considered an acute angle. Revolutions, degrees, and radians are the three types of angles that can be measured. Degrees serve as a more widely used measurement unit. In order for a right angle to be 90 degrees, a circle must be divided into 360 equal degrees.

Answer:C

Step-by-step explanation:

Answer:

A. 4%

Step-by-step explanation:

We can find out the total weight in the beginning by adding 240+10 which is 250

Then we divide 10/250 or we can multiply both sides by 4 to move the denominator to the 1000th which is 40/1000 and remove a 0 from both sides which makes 4/ 100 or 0.04 which is 4%

The percentage increase in x​ is 44 %.

According to the definition of proportion, when two ratios are equivalent, they are in proportion. The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as,

a : b :: c : d = a/b = c/d

There are two other proportional formulas based on direct or indirect variation. If two quantities x and y are in direct proportion, then y = kx and when two quantities x and y are in indirect proportion, then y = k/x, where k is the constant of proportionality.

We are given that x is proportional to ​y where y > 0 and y is increased by 44%.

We have to find the percentage increase in x.​

x is proportional to ​y

=> x = k ​× y

Let say y = 10n

=> x =  k ​× 10n

=> x = 10kn

Now, y = 10n and y is increased by 44%.

=> y = 10n   + (44/100)10n

= 14.4n

=> x =  k ×​14.4n

=> x = 14.4kn

x changed from 10kn to 14.4kn

Increase = 14.4kn - 10kn = 4.4kn

% increase = (4.4kn/10kn) * 100  = 44 %

percentage increase in x​ = 44 %

Thus, the percentage increase in x​ is 44 %.

Step-by-step explanation:

The appropriate p-value for the given test statistic and hypotheses is approximately 0.0253.

Tο determine the apprοpriate p-value fοr the given hypοthesis test, we need tο use the t-distributiοn and the t-statistic value οbtained.

Given:

Null hypοthesis (H0): μ = 130 (pοpulatiοn mean)

Alternative hypοthesis (HA): μ > 130 (pοpulatiοn mean)

T-statistic: t = 2.73

Degrees οf freedοm: df = 5

Tο calculate the p-value, we cοmpare the t-statistic tο the t-distributiοn.

Since the alternative hypοthesis is μ > 130, it is a οne-tailed test, and we are interested in the right tail οf the t-distributiοn.

Using a t-table οr a statistical sοftware, we can determine the p-value assοciated with the t-statistic and the degrees οf freedοm.

Fοr a t-statistic οf 2.73 with 5 degrees οf freedοm, the p-value is apprοximately 0.0257 (assuming a twο-tailed test).

Since we have a οne-tailed test, the apprοpriate p-value is half οf the twο-tailed p-value:

p-value = 0.0257 / 2 = 0.01285

Therefοre, the apprοpriate p-value fοr the given hypοthesis test is apprοximately 0.01285.

The marginal profit if you sell 150 pieces of pie is $1.20 per piece.E. The marginal profit if you sell 150 pieces of pie is the additional profit made by selling one more unit of a good.

Given,The cost to make x servings of apple pie is C(x) = 300+ 0.1x +0.003x².

The price to sell one piece of pie is $4.00.So, the revenue function, R(x) can be written asR(x) = price per unit × number of units soldR(x) = 4x.

The profit function, P(x) is given by the difference between the revenue function and cost function i.e.,P(x) = R(x) - C(x)

Substituting R(x) = 4x and C(x) = 300 + 0.1x + 0.003x² in P(x), we haveP(x) = 4x - (300 + 0.1x + 0.003x²)

P(x) = 4x - 300 - 0.1x - 0.003x²

P(x) = - 0.003x² + 3.9x - 300.

The marginal profit function is given by P'(x) = R'(x) - C'(x).Let's find R'(x) and C'(x).Differentiating R(x) = 4x with respect to x, we getR'(x) = 4Differentiating C(x) = 300 + 0.1x + 0.003x² with respect to x, we getC'(x) = 0.1 + 0.006x.

Substituting R'(x) = 4 and C'(x) = 0.1 + 0.006x in P'(x), we getP'(x) = 4 - (0.1 + 0.006x)P'(x) = 3.9 - 0.006x.

Now, let's find the marginal profit if we sell 150 pieces of pie.

Substituting x = 150 in P'(x), we getP'(150) = 3.9 - 0.006 × 150P'(150) = $1.20 per piece.

The marginal profit if we sell 150 pieces of pie is $1.20 per piece.

The marginal profit is the additional profit made by selling one more unit of a good.So, if we sell one more piece of pie, the profit will increase by $1.20.

Therefore, the area of the region bounded by the curve \(y = f(x) = x^3 - 4x + 1\) and the tangent line y = -x + 3 at (-1,4) is -3/4 square units.

To find the area of the region bounded by the curve \(y = f(x) = x^3 - 4x + 1\) and the tangent line to the curve at (-1,4), we need to determine the points of intersection between the curve and the tangent line.

First, let's find the equation of the tangent line. The tangent line at (-1,4) has the same slope as the derivative of f(x) at x = -1. Let's find this derivative:  \(f'(x) = 3x^2 - 4\).

Evaluating the derivative at x = -1:  

\(f'(-1) = 3(-1)^2 - 4 = 3 - 4 = -1.\).

Therefore, the slope of the tangent line is -1.

Using the point-slope form of a line, the equation of the tangent line is:   y - 4 = -1(x + 1).

Simplifying, we get: y = -x + 3.

Next, we find the points of intersection by setting the curve equation and the tangent line equation equal to each other: \(x^3 - 4x + 1 = -x + 3\).

Rearranging and simplifying, we get:\(x^3 - 3x + 2 = 0\).

Factoring the equation, we find that x = -1 is a root: \((x + 1)(x^2 - x + 2) = 0\)

The quadratic term \(x^2 - x + 2\) has no real roots, so the only intersection point is (-1, 4).

Now, we can find the area of the region bounded by the curve and the tangent line by calculating the definite integral of the positive difference between the curve and the line over the interval from x = -1 to x = 0:

Area = ∫[-1,0] [f(x) - (-x + 3)] dx.

Let's find this integral:

Area = ∫[-1,0] (\(x^3 - 4x + 1 + x - 3\)) dx = ∫[-1,0] (\(x^3 - 3x - 2\)) dx.

Integrating term by term:

\(Area = [\frac{1}{4} x^4 - \frac{3}{2} x^2 - 2x] |[-1,0]\)

\(= [\frac{1}{4} (0)^4 - \frac{3}{2} (0)^2 - 2(0)] - [\frac{1}{4} (-1)^4 - \frac{3}{2} (-1)^2 - 2(-1)]\)

\(= 0 - [\frac{-1}{4} - \frac{3}{2} + 2]\)

\(= -\frac{1}{4} + \frac{3}{2} - 2\)

\(= -\frac{1}{4} + \frac{6}{4} - \frac{8}{4}\)

\(= -\frac{3}{4}\)

Therefore, the area of the region bounded by the curve \(y = f(x) = x^3 - 4x + 1\) and the tangent line y = -x + 3 at (-1,4) is -3/4 square units.

A mathematical operation that is easily performed but highly unlikely to reverse in a reasonable amount of time is known as a "one-way function." One-way functions are fundamental to cryptography, particularly in areas like secure hashing and public-key encryption. These functions are designed to be simple and efficient to compute in one direction but extremely difficult and time-consuming to reverse.

A prime example of a one-way function is the multiplication of two large prime numbers. Multiplying them is a straightforward task, but attempting to factorize the product back into its original primes, known as the "prime factorization problem," is considered computationally infeasible for large numbers. This asymmetry in complexity is utilized in cryptographic systems, such as the RSA encryption algorithm, to ensure the security of sensitive information.

In summary, one-way functions are mathematical operations that can be easily performed but are highly challenging to reverse. Their properties make them invaluable in the realm of cryptography, where they provide the foundation for secure communication and data protection.

The inequality that relates the number of hours to the weekly sales is:

\(450 + 0.20x \ge 35y\)

The complete question implies that we define an inequality that represents the relationship between the number of hours worked in a week and the weekly sales

We make use of the following representation:

\(x \to\) weekly sales from cars.

\(y \to\) hours worked in a week

His weekly salary is then calculated as:

Salary (S) = Earnings per week + Commission * Sales from car

So, we have:

\(S = 450 + 20\% * x\)

Express percentage as decimal

\(S = 450 + 0.20* x\)

\(S = 450 + 0.20x\)

Assume he works for y hours in a week.

His hourly rate is:

\(Hourly = \frac{S}{y}\) --- i.e. weekly salary divided by number of hours

\(Hourly = \frac{450 + 0.20x}{y}\)

For this rate to be at least \(\$35\), the following condition must be true

\(Hourly \ge 35\) --- i.e. is hourly rate must be greater than or equal 35

So, we have:

\(\frac{450 + 0.20x}{y} \ge 35\)

Multiply both sides by y

The remainder when N is divided by 1000 is 106.

The Principle of Inclusion-Exclusion, often known as PIE, offers a method/formula for organizing information about the size of each set, the number of elements in the union of a given set of sets, and the size of all potential set intersections.

From the question,

First, we think about all the possible divisions of the 7×1 board. Since we require at least one tile of each color, we exclude the cases of just one or two pieces.

Three pieces = 5+1+1 , 4+2+1 , 4+1+2 etc (6C2) = 15 ways

Four pieces = 6C3 = 20

Five pieces = 6C4 = 15

Six pieces = 6C5 = 6

Seven pieces =6C6 = 1

Now, we apply the Principle of Inclusion-Exclusion to consider how many ways to color them:

Three pieces : 3³ - 3 × 2³ + 3 = 6

Four pieces: 3⁴ - 3 × 2⁴ + 3 = 36

Five  pieces : 3⁵ - 3 × 2⁵ + 3 = 150

Six pieces : 3⁶ - 3 × 2⁶ + 3 = 540

Seven pieces : 3⁷ - 3 × 2⁷ + 3 = 1806

Adding them together, we get

15×6 + 20×36 + 15×150 + 6×540 + 1×1806 = 8106

Hence, the remainder when it is divided by 1000 is 106.
