What is the selling price of a $470 TV with a 20% markup?

Answer:

D. y= 0.3x2

Step-by-step explanation:

In quadratic functions, the value of a affects the wideness of the graph. The smaller the absolute value of a, the wider the graph. In these choices, 1/3 and 0.3 are the smallest. To understand which is smaller convert both to decimals; 1/3 is 0.3333 repeating. Therefore, 0.3 is slightly smaller and wider.

To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.

Looking at the histograms described:

The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.

The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.

The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.

The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.

Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

Answer:

AB

Step-by-step explanation:

I believe because on the other side it is AE over ED so I just repeated the pattern.

Yes these two lines intersect with each other.

Given,

Co ordinates of line 1 : ( 1 , 2 ) , ( 5 , 3 )

Co ordinates of line 2 : ( 5 , 3 ) , ( 0 , 0 )

So,

Intersection is the meeting point of any lines at a common co ordinate.

The first line has the co ordinates of (1,2) and (5,3).

Similarly second line also has the co ordinate (5,3) and passes through origin.

Since both the lines has one point in common, that means that two lines intersect with each other at point (5,3).

Thus the two given lines will intersect each other at point (5,3)

The values for c and d are c = 4 and d = 5

From the question, we have the following parameters that can be used in our computation:

The square

The side length of the shaded square is calculated as

L = √c² + d²

So, the area is

Area = c² + d²

The shaded square has side length between 6 and 7 cm :

So, we have

6² < c² + d² < 7²

When evaluated, we have

36 < c² + d² < 49

When evaluated, we have

c = 4 and d = 5

i.e.

36 < 4² + 5² < 49

36 < 41 < 49

Hence, the values for c and d are c = 4 and d = 5

none of the provided options (a, b, c, d) appear to be accurate or close to the minimum space required.

To determine the minimum space required for a male restroom design with the given plumbing requirements, we need to consider the minimum space required for water closets and lavatories.

The minimum space required for water closets is typically around 30-36 inches per unit, and for lavatories, it is around 24-30 inches per unit.

Since the design requires a minimum of 12 water closets and 13 lavatories, we can estimate the minimum space required as follows:

Minimum space required for water closets = 12 water closets * 30 inches = 360 inches

Minimum space required for lavatories = 13 lavatories * 24 inches = 312 inches

Adding these two values together, we get a total minimum space requirement of 672 inches.

Among the given options, the closest value to 672 inches is option d) 249. However, this value seems significantly lower than the expected minimum space requirement.

Answer:

7 yards.

Step-by-step explanation:

Assuming both Richard (1,3) and Marlon (-6,3) are on the same altitude/y-axis, we can simply do a addition/subtraction equation to solve this problem. Using both x-axis coordinates, we setup -6 - 1. In turn, we get -7, since one cannot throw something in negative yards, we turn it into a positive. Finally, we get 7 yards in total.

Answer:

7 yards

Step-by-step explanation:

This is the answer because:

1) The question basically is asking what is the distance between the two points: (1,3) and (-6,3)

2) In order to solve for any distance between the points questions, use the formula: d=√((x_2-x_1)²+(y_2-y_1)²)

The solution to the inequality is option B: b ≤ 1 (7/10).

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The inequality equation is 7/2 ≥ b + 9/5.

Write the inequality in standard form -

7/2 = b + 9/5

Simplify the equation -

b = 7/2 - 9/5

b = (35-18) / 10

b = 17 / 10

b = 1 (7/10)

Apply the inequality symbol -

b ≤  1 (7/10)

Therefore, the solution is 1 (7/10).

The matrix M that represents the linear transformation T that maps the triangle P into a new triangle of area 38 is given by M = [1/33 -4/99; 8/33 10/99].

The task is to find a matrix M that represents a linear transformation T which maps the triangle P, defined by the vertices A=[2,1], B=[8,7], and C=[13,3], into a new triangle of area 38.

We can start by computing the area of the triangle P using the formula for the area of a triangle given its vertices:

Area(P) = 1/2 |(B-A) x (C-A)|,

where x denotes the cross product and |.| denotes the magnitude. Substituting the values, we get:

Area(P) = 1/2 |[6,6] x [11,2]| = 1/2 |(-66,66)| = 33.

To find the matrix M, we need to determine how the transformation T maps the vertices of P. Let T(A)=[a,b], T(B)=[c,d], and T(C)=[e,f]. Then, we can set up a system of linear equations based on the fact that the transformation T is linear:

[T(A)] = M [2 1]^T

[T(B)] = M [8 7]^T

[T(C)] = M [13 3]^T

Expanding this system and using the fact that the transformation T maps P into a triangle of area 38, we get:

a(7-3) + c(3-1) + e(1-7) = 38

b(13-3) + d(2-13) + f(8-1) = 38

Solving for a,b,c,d,e, and f, we obtain:

M = [1/33 -4/99; 8/33 10/99]

Therefore, the matrix M that represents the linear transformation T that maps the triangle P into a new triangle of area 38 is given by M = [1/33 -4/99; 8/33 10/99].

Step-by-step explanation:

Let's solve for c.

2.57c+4.98f=12.69

Step 1: Add -4.98f to both sides.

2.57c+4.98f+−4.98f=12.69+−4.98f

2.57c=−4.98f+12.69

Step 2: Divide both sides by 2.57.

2.57c/2.57=-4.98f+12.69/2.57

c=-1.937743f+4.937743

The expected value of y is (D.) 35.5.

The expected value of a discrete random variable is found by multiplying each value of the variable by its corresponding probability and then summing these products. In this case, the probability distribution of y is given in the table.

To find the expected value of y, we need to calculate the sum of the products of each value of y and its corresponding probability.

y * probability = y * P(y)

The expected value of y is E(y) = 100.10 + 200.25 + 300.05 + 400.30 + 500.20 + 600.10
