If she receives $2 off the regular price, p. by using a coupon. her total cost, including 20% for tax and tip, is $9. then the regular price of the lunch special is $11.

Let's figure out why that is so. Romita gets a sushi lunch special at Yoshi's, with a coupon. Romita received a discount of $2 off the regular price, P.

         Let's assume that the price of lunch before the discount is $P.

 Therefore, after the discount, the cost of the lunch is (P - 2).

 Now, let's determine the total cost of the lunch. The price of the lunch is inclusive of 20% tax and tip. This implies that Romita's total cost is 120% of the final cost of the lunch.

    We can represent this information in the equation below:

             Total cost = 120% of (P - 2)

             Total cost = 1.2(P - 2)

    From the given information, we know that the total cost is $9.

    This means we can solve the equation for P.P = (9/1.2) + 2P = 7.5 + 2P = $11

         The regular price of the lunch special is $11.

Here, Y and x are related in such a way that there is a distinct value of y for each value of x, and this relationship is frequently represented as y = f(x), or "f of x." In other words, the same x cannot have more than one value for f(x). The domain and range of the function are the set of values of f(x) that are produced by the values in the domain of the function, which is the set of values of x. In addition to f(x), other abbreviated symbols for functions of the independent variable x include g(x) and P(x), especially when the nature of the function is ambiguous or unspecified.

The function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable). In mathematics, functions are everywhere, and they are crucial for constructing physical relationships in the sciences. German mathematician Peter Dirichlet first offered the modern definition of function in 1837.

Answer:

Step-by-step explanation: First, you need to convert the width of the mural from feet to meters.

1 meter = 3.28084 feet (approximately)

So, 1 foot is approximately 0.3048 meters.

13 feet x 0.3048 meters/foot = 3.9624 meters (rounded to four decimal places)

Therefore, the width of the mural on the scale drawing would be 3.9624 meters.

Next, you need to convert the height of the mural from feet to meters.

24 feet x 0.3048 meters/foot = 7.3152 meters (rounded to four decimal places)

Therefore, the height of the mural on the scale drawing would be 7.3152 meters.

So, the measurements of the mural on a scale drawing using the scale 3m: 2ft would be 3.9624 meters wide and 7.3152 meters tall.

The measure of the angle is 81 degrees, and the measure of its supplementary angle is 99 degrees.

Let x be the measure of the angle in question, and let y be the measure of its supplementary angle.

By definition, supplementary angles add up to 180 degrees, so we have:

x + y = 180

We also know from the problem statement that:

x = y - 18

We can substitute the second equation into the first equation to eliminate y, giving:

(y - 18) + y = 180

Simplifying this equation, we get:

2y - 18 = 180

Adding 18 to both sides, we get:

2y = 198

Dividing both sides by 2, we get:

y = 99

Finally, we can use the equation x = y - 18 to find the measure of the angle in question:

x = 99 - 18 = 81

Therefore, the measure of the angle is 81 degrees, and the measure of its supplementary angle is 99 degrees.

Answer: the answer to the question is A.

Using the data of interquartile range and median given, only option C is correct because approximately 50% of the days had a high temperature greater than 62°F.

We are given that the median high temperature is 62°F and the interquartile range is 32. The interquartile range is the difference between the first and third quartiles, which means that the first quartile is at 62 - 16 = 46°F and the third quartile is at 62 + 16 = 78°F.

Option A: approximately 25% of the days had a high temperature less than 30°F.

Since 30°F is much lower than the first quartile (46°F), it is unlikely that 25% of the days had a high temperature less than 30°F. Therefore, option A is not true.

Option B: approximately 25% of the days had a high temperature greater than 62°F.

This statement cannot be true because the median is already at 62°F, which means that 50% of the days had a high temperature greater than or equal to 62°F. Therefore, option B is not true.

Option C: approximately 50% of the days had a high temperature greater than 62°F.

This statement is true because the median high temperature is 62°F, which means that 50% of the days had a high temperature greater than or equal to 62°F, and the interquartile range is 32, which means that the third quartile is at 78°F. Since the third quartile is above 62°F, approximately 50% of the days had a high temperature greater than 62°F. Therefore, option C is most likely true.

Option D: approximately 57% of the days had a high temperature less than 94°F.

The maximum temperature that can be associated with the interquartile range of 32°F is the third quartile, which is at 78°F. Therefore, we cannot say that approximately 57% of the days had a high temperature less than 94°F. Therefore, option D is not true.

Hence, the most likely true statement is option C: approximately 50% of the days had a high temperature greater than 62°F.

Two methods for proving that two triangles on a Cartesian coordinate plane are congruent are:

Two methods for proving that two triangles on a Cartesian coordinate plane are congruent are:

Side-Side-Side (SSS) congruence theorem: Two triangles are congruent if their corresponding sides are equal in length.

Side-Angle-Side (SAS) congruence theorem: Two triangles are congruent if two corresponding sides and the included angle are equal in both triangles.

To prove that two triangles on a Cartesian coordinate plane are congruent using coordinate geometry, we can follow these steps:

Identify the coordinates of the vertices of the two triangles.

Use the distance formula to find the lengths of the sides of each triangle.

Use the angle formula to find the measure of one angle in each triangle.

Check if the corresponding sides and angles of the two triangles are equal.

If the corresponding sides and angles are equal, the two triangles are congruent by SAS or SSS congruence theorem.

Here are the coordinates of the Triangles:

ΔABC = A(-3, 4) B (-4, 1) C (0,3)

ΔDEF = D(0, 2) E(3, 1) F(2, -2)


To prove whether the two triangles ΔABC and ΔDEF are congruent or not, we need to check if their corresponding sides and angles are equal.

Using the distance formula, we can find the lengths of the sides of each triangle:

AB = √[(4 - 1)² + (-4 - (-3))²] = 3.16

BC = √[(3 - 1)² + (0 - 4)²] = 4.47

AC = √[(3 - 4)² + (0 - (-3))²] = 3.16

DE = √[(2 - 1)² + (3 - 0)²] = 3.16

EF = √[(2-3)² + (-2- 1)²] = 3.16

DF = √[(0-2)² + (2 - - 2)²] = 4.47


Thus, on the basis of the side-side-side postulate, both triangles are congruent because the three sides have an equivalent on each triangle.

The probability that at least 4 of the 10 selected employees are women is approximately 0.671.

Let the probability that a randomly selected employee is a woman is "p",

The 120 employees are men and rest 80 are women,

We have,

⇒ p = (number of women)/(total number of employees),

⇒ p = (200 - 120)/200,

⇒ p = 0.4,

Let X = number of women among the 10 employees selected.

Then X follows a binomial distribution with parameters "n = 10" and "p = 0.4".

The probability of "at-least-4" selected employees are women is expressed as⇒ P(X ≥ 4) = 1 - P(X ≤ 3),

⇒ P(X ≤ 3) = [tex]\[ \sum_{k=0}^{3} \][/tex] C(10,k) × 0.4^k × 0.6^(10-k),

We can then subtract this value from 1 to obtain P(X ≥ 4),

⇒ P(X ≥ 4) = 1 - P(X ≤ 3),

⇒ P(X ≥ 4) ≈ 0.671

To draw the line going through (-6,1) with a slope of -2/3, we can follow these steps:

Plot the point (-6,1) on a coordinate system. This will be one point on the line.

From that point, use the slope to find another point on the line. A slope of -2/3 means that for every 3 units to the right we move, we must move 2 units down. So starting from (-6,1), we can move 3 units to the right and 2 units down to get to the point (-3,-1). This is another point on the line.

Draw a straight line through the two points to represent the line going through (-6,1) with a slope of -2/3.

To write the equation of the line, we can use the point-slope form of the equation:

y - y1 = m(x - x1)

where (x1,y1) is one point on the line, m is the slope, and (x,y) are the coordinates of any other point on the line. Let's choose (-6,1) as our point:

y - 1 = (-2/3)(x - (-6))

Simplifying, we get:

y - 1 = (-2/3)x - 4
