determine the base of a parallelogram with height 6
feet and area 15 square feet.

Answers

To determine the base of a parallelogram, we can use the formula for the area of a parallelogram, which is A = b*h, where A is the area, b is the base, and h is the height.

We are given the height (h) and the area (A), so we can rearrange the formula to solve for the base (b):
b = A/h

Substituting the given values for A and h:
b = 15/6

Simplifying:
b = 2.5

Therefore, the base of the parallelogram is 2.5 feet.

Consider two dice-throwing experiments. Find the probabilities
of the following events.
Let X = sum of the two dice:
P (X = 5)
P( 2 ≤ X ≤ 6)
P(X = 5 or X = 10

Answers

So the probabilities of the given events are:

P(X = 5) = 1/9
P(2 ≤ X ≤ 6) = 5/12
P(X = 5 or X = 10) = 7/36

To find the probabilities of the given events, we need to consider all the possible outcomes of the two dice-throwing experiments and the number of favorable outcomes for each event.

There are 6 possible outcomes for each die, so the total number of possible outcomes for the two dice is 6 × 6 = 36.

For the event X = 5, the favorable outcomes are (1, 4), (2, 3), (3, 2), and (4, 1). So the probability of this event is P(X = 5) = 4/36 = 1/9.

For the event 2 ≤ X ≤ 6, the favorable outcomes are (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (2, 1), (2, 2), (2, 3), (2, 4), (3, 1), (3, 2), (3, 3), (4, 1), (4, 2), and (5, 1). So the probability of this event is P(2 ≤ X ≤ 6) = 15/36 = 5/12.

For the event X = 5 or X = 10, the favorable outcomes are (1, 4), (2, 3), (3, 2), (4, 1), (4, 6), (5, 5), and (6, 4). So the probability of this event is P(X = 5 or X = 10) = 7/36.

B.{-1/3+(-10)}+{7+2/3+5
C.{-1/3+7+(-10)}+(5+2/3)
D.{5+(-1/3)+(-10)}+(2/3+7)

Answers

Option D, {5+(-1/3)+(-10)}+(2/3+7), would be easier to simplify if we use the commutative property.

What is the commutative property, and how can it be used to simplify expressions?

The commutative property is a property of addition and multiplication that allows us to change the order of the numbers being added or multiplied without changing the result.

That is, [tex]a + b = b + a[/tex] and [tex]a \times b = b \times a[/tex].

To simplify expressions, we can use the commutative property to rearrange the order of the terms in a way that makes the arithmetic easier to perform.

Find the expression:

We are given the expression -1/3-10+7+2/3+5, and we want to know which option would be easier to simplify using the commutative property.

Option D, {5+(-1/3)+(-10)}+(2/3+7), would be easier to simplify using the commutative property because we can group the terms that have like terms together. Specifically, we can group the negative terms together and the positive terms together:

{5+(-1/3)+(-10)}+(2/3+7) = {(5)+[(-1/3)+(-10)]}+{(2/3)+7}

Now we can simplify each group separately. For the first group, we can add the terms inside the brackets using the commutative property:

{-1/3+(-10)} = -10 - 1/3 = -31/3

For the second group, we can add the terms directly:

{2/3+7} = 2/3 + 21/3 = 23/3

Substituting these results back into the original expression, we get:

-1/3-10+7+2/3+5 = -31/3 + 23/3 + 5

Now we can add the terms directly to get:

-31/3 + 23/3 + 5 = -8/3 + 5 = 7/3

Therefore, the expression simplifies to 7/3.

A certain rectangular tarp covers 200 square meters. Its width is 5
meters. How long is the tarp?

Answers

The length of the tarp with an area of 200 square meters is 40 meters.

What is the length of the tarp?

The area of a rectangle is expressed as;

Area = length × width

Given that;

Area = 200 square metersWidth =  5metersLength = ?

When a rectangular tarp has an area of 200 square meters and a width of 5 meters, we can use the above formula to find the length of the tarp.

Plug these values into the formula and solve for the length:

Area = length × width

200 = Length x 5

To solve for Length, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 5:

200/5 = Length

This simplifies to:

40 = L

L = 40

By answering the supplied question, we may infer that the response is slope As a result, the equation's y-intercept is equal to -8.

what is slope?

A line's slope determines how steep it is. The gradient is mathematically expressed as gradient overflow. By dividing the vertical change (run) between two spots by the height change (rise) between the same two locations, the slope is determined. The equation for a straight line, y = mx + b, is written as a curve form of an expression. When the slope is m, b is b, and the line's y-intercept is located (0, b). For instance, the y-intercept and slope of the equation y = 3x - 7 (0, 7). The location of the y-intercept is where the slope of the path is m, b is b, and (0, b).

The slope of the line is represented by the coefficient of x in the equation Y = -6x - 8.

As a result, the equation's slope is -6.

Answers

After 3 years and 9 months, the copier is worth $30,750. After 5 years, the salvage value of the copier is $35,000. The domain of the function is 0 <= t <= 5.

a. To find the value of the copier after 3 years and 9 months, we need to plug in the value of t into the function V(t). Since 3 years and 9 months is equivalent to 3.75 years, we plug in 3.75 for t:
V(3.75) = 3400(3.75) + 18000
V(3.75) = 12750 + 18000
V(3.75) = 30750
Therefore, the copier is worth $30,750 after 3 years and 9 months.

b. To find the salvage value of the copier after 5 years, we need to plug in 5 for t into the function V(t):
V(5) = 3400(5) + 18000
V(5) = 17000 + 18000
V(5) = 35000
Therefore, after 5 years, the salvage value of the copier is $35,000.

c. The domain of this function is the set of all possible values of t. Since the function is defined for the first 5 years of use, the domain is 0 <= t <= 5.

Determine at what value (s) of m will the given quadratic equation have a repeated solution. 3x^(2)+4mx+m=0

Answers

The values of m that will result in a repeated solution for 3x^(2)+4mx+m=0  are m = 0 and m = 3/4.

The given quadratic equation is 3x^(2)+4mx+m=0. In order to find the value(s) of m that will result in a repeated solution, we need to use the discriminant of the quadratic formula.

The discriminant of the quadratic formula is given by b^(2)-4ac, where a, b, and c are the coefficients of the quadratic equation.

In the given equation, a = 3, b = 4m, and c = m.

Plugging these values into the discriminant, we get:

(4m)^(2)-4(3)(m) = 16m^(2)-12m = 0

A repeated solution occurs when the discriminant is equal to 0. So, we need to solve the equation 16m^(2)-12m = 0 for m.

Factoring out a common factor of 4m, we get:

4m(4m-3) = 0

This gives us two possible values for m:

4m = 0 or 4m-3 = 0

Solving for m, we get:

m = 0 or m = 3/4

Therefore, the values of m that will result in a repeated solution for the given quadratic equation are m = 0 and m = 3/4.

the coordinates of the vertices of △RST are R(−3, −1) , S(−1, −1) , and T(−4, −5) . The coordinates of the vertices of △R′S′T′ are R′(3, −3) , S′(3, −1) , and T′(−1, −4) . What is the sequence of transformations that maps △RST to △R′S′T′?

Answers

The sequence of transformations that maps △RST to △R′S′T′ is a translation of 6 units to the right and 2 units down, followed by a reflection across the y-axis, and finally a rotation of 90 degrees counterclockwise about the origin.

What is the sequence of transformation?

In mathematics, a sequence of transformations refers to a series of geometric transformations performed on a shape to create a new shape. These transformations can include translations, rotations, reflections, and dilations.

The sequence of transformations is the order in which the transformations are performed. The order matters because different sequences of transformations can lead to different final shapes.

For example, to transform a triangle into a new position, we might first perform a translation to move the triangle to a new location, then perform a rotation to change its orientation, and finally perform a reflection to flip the triangle across a line. The sequence of transformations in this case is translation-rotation-reflection.

Sequences of transformations are used in geometry to analyze and describe shapes and to solve problems related to symmetry, congruence, and similarity. They are also used in computer graphics and animation to create 2D and 3D shapes that can be moved and transformed on a screen.

To map △RST to △R′S′T′, we need to perform a sequence of transformations that includes translations, rotations, reflections, and/or dilations. Here's one possible sequence of transformations:

Translation: We can translate △RST by 6 units to the right and 2 units down to get a new triangle that has R at (3, -3), S at (5, -3), and T at (2, -7).

Reflection: We can reflect the translated triangle across the y-axis to get a new triangle that has R′ at (-3, -3), S′ at (-5, -3), and T′ at (-2, -7).

Rotation: We can rotate the reflected triangle 90 degrees counterclockwise about the origin to get a new triangle that has R′ at (3, -3), S′ at (3, -1), and T′ at (-1, -4).

Therefore, the sequence of transformations that maps △RST to △R′S′T′ is a translation of 6 units to the right and 2 units down, followed by a reflection across the y-axis, and finally a rotation of 90 degrees counterclockwise about the origin.

Kind of confused on this one.

Answers

Answer: (-6, 4)

Explanation: If you were to plot all of those only 3 of them would line up to make it a more positive association. (-6,4) would be an outlier not making the line more of a positive association

(fyi apologies if the explanation doesn’t make sense, im horrible at explaining things)

Exercise V (4×5=20 points )
True or False? Explain clearly. 1. Every matrix with ones down the main diagonal is invertible. 2. Let A,B,M be square matrices of the same size. If B=M−1AM, then detB=detA. 3. Suppose that a matrix A satisfies the equation A2=A. Then det A=0. 4. If A and B are invertible n×n matrices, then A is invertible and the inverse of AB is B−1A−1

Answers

The inverse of AB is B−1A−1

1. True. Every square matrix with ones down the main diagonal has an inverse, since the diagonal elements are all non-zero.
2. False. Generally, the determinant of B does not necessarily equal the determinant of A, even when B is a product of A and other matrices.
3. True. If a matrix A satisfies the equation A2=A, then its determinant is 0, since A=A2 implies detA=det(A2)=detA×detA=detA2=0.
4. True. If A and B are both invertible n×n matrices, then AB is also invertible, and the inverse of AB is B−1A−1.

One hypothesis suggests that natural selection favored a dominant sporophyte over the haploid gametophyte because the sporophyte allowed for a greater level of genetic diversity. Suppose a recessive allele arises in a plant in an environment where it is mildly disadvantageous. The same allele provides a significant advantage to the plant in a slightly different environment. Explain why such a recessive allele is more likely to persist in a fern than a moss. Hint: think about the basic genetics that you learned in Bio 101 and recessive vs dominant alleles and their effects on phenotype.

What was the impact of the prison reform? Procter & Gamble (P&G) is the worlds largest consumer products company. Some of its category-defining brands include Ivory soap, Tide detergent, Crest toothpaste, and Pampers diapers. Among its many offerings, P&G has more than 20 consumer brands in its lineup that achieve over 66.8 billion dollars or three (3) trillion pesos in 2018. P&Gs iconic brands are a result of a clearly formulated and effectively implemented company strategy. The company pursues a strategy which attempts to create higher perceived value for its customers than its competitors by delivering products with unique features and attributes. Creating higher perceived value generally goes along with higher product costs due to greater innovation efforts and promotion expenses, among other things. Successful differentiators are able to command a premium price for their products, but they must also control their costs. In addition, the company was able to achieve its market leader position through its top management commitment that collaborates even with the lower-level managers in the company.In recent years, however, P&Gs strategic position has weakened considerably and seems to be losing rather than winning. P&G lost market share in key "product-country combinations," including beauty in the United States and oral care in China, amid an overall lackluster performance in many emerging economies. As a consequence, profits have declined. P&G posted a sustained competitive advantage in recent years; its stock market valuation has fallen, while its competitors Unilever, Colgate-Palmolive, and Kimberly-Clark posted strong gains. Many wonders when P&G will play to win again.Answer the following questions: (3 items x 10 points)1. Which phase in the evolution of strategic management is present in the given case?2. Which type of strategy is being employed by P&G based on the given case study?3. How will P&G regain its market position based on the concept of competitive advantage?
