Answer:

LM = 40

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{LM}{LO}[/tex] = [tex]\frac{LN}{LP}[/tex] ( substitute values )

[tex]\frac{LM}{5}[/tex] = [tex]\frac{14+2}{2}[/tex] = [tex]\frac{16}{2}[/tex] = 8 ( multiply both sides by 5 )

What is probability?

In playing cards, it can be used to predict the likelihood of a certain outcome or to make decisions based on the probability of certain events occurring.

(a) The probability of the questions being history, literature, and science in that order is 5/18 x 6/17 x 7/16, which is 0.04.

(b) The probability of all three questions being literature questions is 6/18 x 5/17 x 4/16, which is 0.024.

(c) The probability of the first question being science, the second history, and the third science is 7/18 x 5/17 x 7/16, which is 0.05.

The probabilities of each of these scenarios can be calculated by multiplying the probabilities of drawing each of the three cards in the desired order.

For the first scenario, the probability of drawing a history question is 5/18, the probability of drawing a literature question is 6/17 (since there is one fewer card), and the probability of drawing a science question is 7/16 (since there are two fewer cards).

Multiplying these together gives us the probability of the questions being history, literature, and science in that order, which is 0.0771.

Answers

After answering the presented question, we can conclude that angles  m/CQW = 180° - 125° - 50° => m/CQW = 5° Therefore, m/CQW = 5°.

what are angles?

An angle is a shape in Euclidean geometry that is made up of two rays that meet at a point in the middle known as the angle's vertex. Two rays may combine to form an angle in the plane where they are located. When two planes collide, an angle is generated. They are referred to as dihedral angles. An angle in plane geometry is a possible configuration of two radiations or lines that express a termination. The word "angle" comes from the Latin word "angulus," which meaning "horn." The vertex is the place where the two rays, also known as the angle's sides, meet.

The measure of an inscribed angle is half the measure of its intercepted arc, according to the inscribed angle theorem.

Because C and Q are on the same diameter MQ, m/CQM = 90°. As a result, the intercepted arc CZQ measures 180° - 90° = 90°.

Similarly, because W and Q are on the CW diameter, we have m/CWQ = 90°. As a result, the intercepted arc WVQ measures 180° - 90° = 90°.

m/CQW = 180° - m/CVQ - m/ZVW

m/CQW = 180° - 125° - 50°

m/CQW = 5°

Therefore, m/CQW = 5°.

There is a 1.8% probability that a customer will buy clothes, shoes, AND jewelry.

This statement is false. The probability that a customer buys clothes, shoes, and jewelry is not given

How to solve the problem ?

Let's denote the event that a customer buys clothes by C, the event that a customer buys jewelry by J, and the event that a customer buys shoes by S. We are given that the probabilities of these events are independent. Therefore, the probability of a customer buying clothes and shoes, denoted by C and S, is simply the product of the probabilities of buying clothes and buying shoes, which is 0.6 × 0.3 = 0.18. Similarly, the probability of a customer not buying shoes and buying jewelry, denoted by S' and J, is simply the product of the probabilities of not buying shoes and buying jewelry, which is 0.7 × 0.1 = 0.07.

Using these probabilities, we can now check the statements:

There is a 15% probability that a customer buys NO clothes, NO shoes, and NO jewelry.

This statement is true. The probability that a customer buys none of these items is simply the complement of the probability that the customer buys at least one of them. Using the inclusion-exclusion principle, we have:

P(C ∪ J ∪ S) = P(C) + P(J) + P(S) - P(C ∩ J) - P(C ∩ S) - P(J ∩ S) + P(C ∩ J ∩ S)

P(C ∪ J ∪ S) = 0.6 + 0.1 + 0.3 - 0 - 0.18 - 0 + P(C ∩ J ∩ S)

P(C ∪ J ∪ S) = 0.52 + P(C ∩ J ∩ S)

Therefore, the probability that a customer buys none of these items is:

P((C ∪ J ∪ S)') = 1 - P(C ∪ J ∪ S) = 0.48 - P(C ∩ J ∩ S)

We are not given the value of P(C ∩ J ∩ S), but we know that it cannot be negative. Therefore, the maximum value of P((C ∪ J ∪ S)') is 0.48, which corresponds to the case where P(C ∩ J ∩ S) = 0. In this case, the probability that a customer buys none of these items is 0.48, which is 15% of 1.

There is a 70% probability that a customer does NOT buy shoes.

This statement is true. The probability that a customer does not buy shoes is simply the complement of the probability that the customer buys shoes, which is 0.3. Therefore, the probability that a customer does not buy shoes is 1 - 0.3 = 0.7, which is 70% of 1.

There is an 8.5% chance that a customer buys jewelry.

This statement is false. The probability that a customer buys jewelry is not given directly. However, we can use the information about the probability of not buying shoes and buying jewelry to find it. We have:

P(S' ∩ J) = P(S') × P(J) = 0.7 × 0.1 = 0.07

Therefore, the probability that a customer buys jewelry is:

P(J) = P(S' ∩ J) + P(S ∩ J) = 0.07 + 0 = 0.07

This is 7% of 1, not 8.5%.

There is a 1.8% probability that a customer will buy clothes, shoes, AND jewelry.

you can make one of the following investments:

Option 1: $50 initial investment with an average annual growth rate of 9% starting at age 30

Option 2: $50 initial investment with an average annual growth rate of 8% starting at age 20

Option 3: $100 initial investment with an average annual growth rate of 7% starting at age 25 ​

Answers

Based on these calculations, Option 3 yields the highest future value at age 35.

How to solve

To compare the investment options at different ages, we can use the future value formula:

FV = PV * (1 + r)^t

where:

FV = future value of the investment

PV = present value or initial investment

r = annual growth rate (as a decimal)

t = number of years the investment grows

Here are the general equations for each option:

Option 1: FV1 = 50 * (1 + 0.09)^(t - 10)Option 2: FV2 = 50 * (1 + 0.08)^tOption 3: FV3 = 100 * (1 + 0.07)^(t - 5)

To compare the options at ages 20, 25, 30, and 35, calculate the future value for each option at those ages by plugging in the corresponding value of t.

Age 20:

FV1 = N/A (Option 1 hasn't started yet)

FV2 = 50 * (1 + 0.08)^0 = $50

FV3 = N/A (Option 3 hasn't started yet)

Age 25:

FV1 = N/A (Option 1 hasn't started yet)

FV2 = 50 * (1 + 0.08)^5 ≈ $73.86

FV3 = 100 * (1 + 0.07)^0 = $100

Age 30:

FV1 = 50 * (1 + 0.09)^0 = $50

FV2 = 50 * (1 + 0.08)^10 ≈ $107.95

FV3 = 100 * (1 + 0.07)^5 ≈ $140.26

Age 35:

FV1 = 50 * (1 + 0.09)^5 ≈ $77.16

FV2 = 50 * (1 + 0.08)^15 ≈ $157.46

FV3 = 100 * (1 + 0.07)^10 ≈ $196.72

1. Find a common denominator for 1/3 and 1/12 by dividing each whole into the same number of equal parts.

Answers

Answer: To find a common denominator for 1/3 and 1/12, we need to divide each whole into the same number of equal parts. The denominator of 1/3 represents three equal parts, so we can divide the whole into three parts. The denominator of 1/12 represents twelve equal parts, so we can divide the whole into twelve parts.

The smallest number of parts that both 3 and 12 divide into evenly is 12. So, we can represent 1/3 as 4/12 by dividing each of the three equal parts into four smaller equal parts. And we can represent 1/12 as 1/12 by dividing each of the twelve equal parts into one smaller equal part.

Therefore, a common denominator for 1/3 and 1/12 is 12, and we can rewrite the fractions as:

Required length of HF, angle H, angle F are 12.05 unit, 44.2°, 80.5° respectively.

How to find the length of the third side of a triangle when length of two sides are already given?

To find the length of the third side, HF, we can use the Law of Cosines, which states that:

c² = a² + b² - 2ab cos(C)

where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

In this case, we have:

HF² = HG² + GF² - 2HG × GF × cos(HGF)

HF² = 7² + 13² - 2 × 7 × 13 × cos(136°)

HF² = 49 + 169 - 182cos(136°)

HF² ≈ 145.35

Taking the square root of both sides,

HF ≈ 12.05

So the length of the third side, HF, is approximately 12.05 units.

To find the angles, we can use the Law of Sines, which states that,

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides opposite angles A, B, and C, respectively.

In this case, we know the lengths of HG, GF, and HF, so we can find the angles H and F,

sin(H) / 7 = sin(136°) / 12.05

sin(H) ≈ 0.689

H ≈ 44.2°

sin(F) / 13 = sin(136°) / 12.05

sin(F) ≈ 0.992

F ≈ 80.5°

Therefore, the length of HF is approximately 12.05 units, the angle H is approximately 44.2°, and the angle F is approximately 80.5°.

Find the value of each variable in the parallelogram. Round your answers to the nearest tenth, if necessary. G a = (46) K (3a +19) b H 56°​

Answers

The value of every variable in the parallelogram is: a = 9 HK = 27.0 GK = 46 G = 63.5°

What do you mean by Parallelogram ?

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.These shapes include squares, rectangles, rhombuses, and rhomboids. All of these shapes have four sides, four corners, and four angles

We know that sides of a parallelogram are parallel and congruent, as opposite angle

According to question  that GA equals HK, as:

46 is equal to 3a plus 19 When we subtract 19 from both sides, we get:

27 x 3a is the result of dividing both sides by 3:

we know that opposite angles in a parallelogram are congruent, we can use a = 9. Since angle H is 56 degrees, angle K must also be 56 degrees. The length of side HK can be determined using the Law of Cosines:

HK2 = GA2 + GK2 - 2(GA)(GK)cos(H) When we substitute the values we are familiar with, we obtain:

After solving the equation we obtain: HK2 = 462 + (3a + 19)2 - 2(46)(3a + 19)cos(56°).

HK2 = 2112 + 9a2 + 342a - 2764cos(56°) HK2 = 2112 + 9(9)2 + 342(9) - 2764cos(56°) HK2  732.4 By taking the square root of both sides, we obtain the following results:

∵ GA = 46, we can use the parallelogram's opposite sides being congruent to determine the length of side GK: HK  27.0

Then, we can use the Law of Cosines to determine the angle G's measurement:

cos(G) = (HK2 + GA2 - GK2) / (2(HK)(GA)) Using the values we are familiar with, we get,

cos(G) = (27.02 + 462 - 462) / (2(27.0)(46)) cos(G)  0.465 Using the inverse cosine, we get the following:

G ≈ 63.5°

Hence, the worth of every variable in the parallelogram is:

a = 9 HK = 27.0 GK = 46 G = 63.5°

Suppose he got dilates the rectangle shown below with the center of dilation at 0,0 and a scale factor of 2, and then translates the figure 1 unit to the left. What will be the coordinates of the vertices of the similar figure that results

Answers

The vertices of the similar figure that results from the dilation and translation will be A'' = (2a - 1, 2b), B'' = (2c - 1, 2b), C'' = (2c - 1, 2d), and D'' = (2a - 1, 2d).

Assume that the rectangle's four vertices are A, B, C, and D, with the corresponding coordinates being (a, b), (c, b), (c, d), and (a, d).

First, enlarge the rectangle.

We must multiply the coordinates of each vertex by the scale factor of two in order to enlarge the rectangle. We can apply the following formulas because the centre of dilation is at (0, 0):

Old x-coordinate + 2 equals the new x-coordinate

Old y-coordinate + 2 times the new y-coordinate

Therefore, following dilation, the new coordinates for the vertices will be: A' = (2a, 2b)

B' = (2c, 2b)

C' = (2c, 2d)

D' = (2a, 2d)

Translate the Figure in Step 2

The x-coordinate of each vertex must be reduced by one in order to translate the figure one unit to the left. Therefore, following translation, the vertices' new coordinates will be: A' = (2a - 1, 2b)

B'' = (2c - 1, 2b)

C'' = (2c - 1, 2d)

D'' = (2a - 1, 2d)

As a result, A'' = (2a - 1, 2b), B'' = (2c - 1, 2b), C'' = (2c - 1, 2d), and D'' = (2c - 1, 2d) will be the vertices of the similar figure that comes from the dilation and translation. (2a - 1, 2d).

Paula wants to retire. She has an account that has $250,000. It is earning an APR of 5.63%. What is the monthly yield on the account for a 20-year period?

(Please round your answer to the nearest dollar.)

Answers

Paula's account will earn a total of $282,546.60 in interest over the next 20 years, in addition to her initial investment of $250,000.

The monthly yield on Paula's account can be calculated using the following formula:

Monthly Yield = (Account Balance x Annual Percentage Rate) ÷ (12 x 100)

Monthly Yield = (250,000 x 5.63) ÷ (12 x 100) = $1,177.29

So, Paula's account will earn a monthly yield of $1,177.29 for the next 20 years. To calculate the total amount earned over the 20-year period, we can multiply the monthly yield by the number of months in 20 years (i.e., 240):

Total Earnings = Monthly Yield x Number of Months

Total Earnings = $1,177.29 x 240

Total Earnings = $282,546.60

Given the polynomial 3x3 − 4x2 + 9x − 12, rewrite the polynomial as a product of binomials.

(x2 + 3)(3x + 4)
(x2 + 3)(3x − 4)
(x2 − 3)(3x + 4)
(x2 − 3)(3x − 4)

Answers

Answer:

(x^2+3)(3x-4)

Step-by-step explanation:

To answer this question we can employ a technique called factor by grouping. This strategy has us factor out values from the first two numbers and last two numbers to simplify the expression.

3x^3-4x^2+9x-12

x^2(3x-4)+3(3x-4)

(x^2+3)(3x-4)

Therefore, the answer is the second option.

Suppose you wish to invest money safely and are trying to decide between stock options in two companies. The average rates of return are the same for both companies but, one company has a much larger standard deviation of its rates of return. a. Which company should you invest in? The company with the smaller standard deviation The company with the larger standard deviation b. Why is this the better choice?

Answers

Answer:

If the average rates of return are the same for both companies, but one company has a much larger standard deviation of its rates of return. You should invest in a company with a smaller standard deviation.

This is the better choice because a larger standard deviation means that the company's returns are more variable, which implies more risk. While higher risk can result in higher returns, it can also result in significant losses. Investing in a company with a smaller standard deviation of its rates of return will likely result in a more stable return on investment and therefore be a safer investment.

In general, investors should consider both the average and variability returns when making investment decisions. While higher average returns are desirable, they may not be worth the additional risk if the variability of returns is too high.

The diameter of a circle is 8 kilometers. What is the circle's area? Use 3.14 for ​. square kilometers

Answers

Answer:

The formula for area of a circle is A = π r²

Step-by-step explanation:

We have the diameter of the circle (8 kilometers) which gives us enough information to find the area of this cicle. We can find the radius from the dimeter (by using the simple formula r=d/2) the radius is always half of the diameter. So 8 km/2= 4 kilmeters so the radius is 4 kilometers.

now that we have the radius we can solve this problem

π×4²= 50.24

what I did was that I multiplied 3.14× than i got 50.24

since you want your answer in square km the answer would be 50.24²Kilometers

i hope this helps :)

z varies directly as √√x and inversely as y. If: = 179 when x=25 and y= 7, find zifx = 64 and y = 4. (Round off your answer to the nearest hundredth.)
z=

Answers

We know that z varies directly as √√x and inversely as y, which can be written as:

z = k(√√x)/y

where k is the constant of proportionality.

To find the value of k, we can use the values given when x = 25 and y = 7:

179 = k(√√25)/7

179 = k(5/7)

k = (179*7)/5

k = 250.6

Now we can use this value of k to find z when x = 64 and y = 4:

z = 250.6(√√64)/4

z = 250.6(2)/4

z = 125.3

Therefore, z ≈ 125.3 when x = 64 and y = 4.

Consider the following system of two linear equations:

3y + 2x = 15
x – y = 0

Select the graph that correctly displays this system of equations and point of intersection.

Answers

The answer is x = 3 y=3. This can be solved by reorganising the equation 2x + 3y = 15, x-y=0.

What is Multiplication Zero Property?

This property is true for all real numbers, including integers, fractions, decimals, and any other real number. The Multiplication Zero Property states that the product of any number and zero is equal to zero.

Reorganising the equation:

2x + 3y = 15

x-y=0

To find the solution, multiply both parts of the equation by a multiplier, as in 2x+3y=15.

2(x-y)=0 x 2

Utilize the multiplicative distributional rule.

2x+3y=15

2x-2y=0 x 2

Application of the Multiplication Zero Property

2x+3y=15

2x-2y=0

Separate the two formulas: 2x+3y-(2x-2y)=15-0

2x+3y-2x+2y=15

Take the parentheses off

3+2=15

Expressions combined: 5y=5

Multiply both sides of the equation by the value of the variable: y = 15/5

Take out the joining piece. y=3

Substitute 0 for 2x-2x-2x in one of the computations.

2x-6=0 is used to determine the product.

In the calculation, 6 should be shifted to the left: 2x=6

Add the variable's value to both ends of the equation, then subtract it:

x = 6/2

Take out the intermediary: 2 = 3

The  answer is x = 3 y=3.
