what theorem can be used to find segment lengths in a triangle with a segment drawn parallel to a side of the triangle?

The probability that at least one person receives exactly one aces in their 52 cards is 4/52= 1/13

We define the following events:

A: person A receives exactly two aces in their five cards.

B: person B receives exactly two aces in their five cards.

C: person C receives exactly two aces in their five cards.

We need to calculate P(A∪B∪C). According to the principle of inclusion and exclusion:

P(A∪B∪C)= P(A)+P(B)+P(C)-P(A∩B)-P(A∩C)-P(B∩C)+P(A∩B∩C)

Total outcomes is equal to  because there 52 cards and we select 5 of them.

The probability of each event is given by:

P(A)=P(B)=P(C)===0.0399

where the possible outcomes are 2 aces and 3 of the other cards.

Then, the intersections of the events mean that one player gets 2 aces and the other gets 2 aces too.

P(A∩B)=P(B∩C)=P(A∩C)==0.0001

Finally,

P(A∩B∩C)=0 because it is not possible that the three events occur at the same time due to there are only 4 aces.

P(A∪B∪C)= 0.0399+0.0399+0.0399-0.0001-0.0001-0.0001+0

P(A∪B∪C)=0.1194

The probability that at least one person receives exactly two aces in their five cards is 0.1194.

Sarah's new total cost will be $1,685.73 including 15% gratuity.

To find the new total cost, we can first calculate the cost of shipping, which is 2% of the total cost of the computer repair.

Shipping = 2% * 1,444.50 = 28.89

We can then subtract the shipping cost from the original total cost to find the cost of the computer repair, excluding shipping.

Computer repair cost (excluding shipping) = 1,444.50 - 28.89 = 1,415.61

Now we can add the 15% gratuity to the cost of the computer repair, excluding shipping:

Gratuity = 15% * 1,415.61 = 212.34

Finally, we can add the gratuity and shipping cost back to the original cost of the computer repair to find the new total cost:

New total cost = 1,444.50 + 28.89 + 212.34 = $1,685.73

So, Sarah's new total cost will be $1,685.73 including 15% gratuity.

Answer: 16

Step-by-step explanation:

First, calm down.

The area of the trapezoid cannot be found in a straightforward way.

Instead, what we need to do here is divide the trapezoid into two parts, a right triangle and a trapezoid.

Finding the area of the right triangle is easy. You just need to multiply the sides and divide it by 2.

Area of right triangle = 5*4/2 = 10

Next, you need to find the area of the trapezoid.

Area of trapezoid(small) = (2+1)*4/2 = 6

All you need to do now is add the area of these two together, and you get 16.

Answer:

A = 16 units²

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between the parallel sides b₁ and b₋₂

here h = 4 , b₁ = 6 and b₂ = 2

A = [tex]\frac{1}{2}[/tex] × 4 × (6 + 2) = 2 × 8 = 16 units²

$38,400

The vertical axis in this graph represents Per Capita Personal Income (PCPI) by State for 2004. The number given to us is $52,000, and the other number given is $20,000. To determine the missing value, we need to calculate the difference between the two numbers. We do this by subtracting $20,000 from $52,000.

$52,000 - $20,000 = $32,000

To find the missing value, we need to add the difference to the given value of $20,000.

$20,000 + $32,000 = $52,000

The final function after transformations, is [tex]f(x +8) = \sqrt[3]{x+8} - 3[/tex]

The technique of altering an existing graph or graphed equation to create a different version of the following graph is known as graph transformation. The modification of algebraic equations is a typical form of algebraic problems. Sometimes graphs are translated, or moved about the xy-plane; sometimes they are stretched, rotated, inverted, or a combination of these transformations.

Now, there are 2 different transformations applied to the function here.

First Transformation:

[tex]f(x) = \sqrt[3]{x}[/tex] is translated 3 units in the negative y direction.

After transformation, the function is [tex]f(x) = \sqrt[3]{x} - 3[/tex].

Second Transformation:

The function [tex]f(x) = \sqrt[3]{x} - 3[/tex] is translated 8 units in the negative x direction.

After transformation, the function is [tex]f(x +8) = \sqrt[3]{x+8} - 3[/tex].

a. To prove the product property for logarithms using a base of 3 and solutions of 3, 9, 27, 81, and 243, we can start with the equation: log3(xy) = log3x + log3y

Let's say we want to find log3(81 * 27)
We know that log3(81) = 4, and log3(27) = 3
So, log3(81 * 27) = log3(81) + log3(27) = 4 + 3 = 7

We can verify this by using the fact that we know the solution of log3(81*27) is 243, and 3^7 = 243.

b. To prove the quotient property for logarithms using a base of 3 and solutions of 3, 9, 27, 81, and 243, we can start with the equation: log3(x/y) = log3x - log3y

Let's say we want to find log3(81 / 27)
We know that log3(81) = 4, and log3(27) = 3
So, log3(81 / 27) = log3(81) - log3(27) = 4 - 3 = 1

We can verify this by using the fact that we know the solution of log3(81/27) is 9, and 3^1 = 9.

c. To prove the power property for logarithms using a base of 3 and solutions of 3, 9, 27, 81, and 243, we can start with the equation: log3(x^n) = n*log3x

Let's say we want to find log3(81^3)
We know that log3(81) = 4
So, log3(81^3) = 3 * log3(81) = 3 * 4 = 12

We can verify this by using the fact that we know the solution of log3(81^3) is 243, and 3^12 = 243.

In all the above examples, we can see that the properties are upheld, and we can use the log3(y) values of 3, 9, 27, 81, and 243 to prove the Product, Quotient and Power property of logarithms with base 3.

The common ratio that Yui should use in her recursive formula is 1.05. This is because each month's total is 5% greater than the previous month's total, which can be represented as 1 + (0.05) = 1.05.

The function f(x) = 4x/(x-16) has vertical asymptotes at x = 16.

To see this, we can factor the denominator:

f(x) = 4x/(x-16) = 4x/x - 16

As x approaches 16 from the left or right, the denominator x-16 approaches 0, but the numerator 4x does not. This means that the function approaches infinity or negative infinity as x approaches 16, indicating a vertical asymptote at x = 16.

To find the end behavior of the function, we can look at the behavior of the function as x approaches positive or negative infinity. We can see that f(x) = 4x/(x-16)

As x increases without bound, x-16 increases without bound. This means that the denominator becomes larger and larger, making the function approach 0 as x approaches positive infinity.

As x decreases without bound, x-16 decreases without bound as well, this means that the denominator becomes smaller and smaller, making the function approach 0 as x approaches negative infinity.

Therefore, the function has a vertical asymptote at x = 16 and approaches 0 as x approaches positive and negative infinity.

The absolute value inequality for the hearing range of each animal is mod(e - 6008) ≤ 5992 and mod(m - 46000) ≤ 45000, respectively.

An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative. You can write an absolute value inequality as a compound inequality. This holds true for all absolute value inequalities. You can replace > above with ≥ and < with ≤.

To solve absolute-value inequalities, first, we must drop the absolute-value bars and restate the inequality in one of two ways, depending on the case.

According to the question,

The elephant can hear: 16 ≤ e ≤ 12000

The avg hearing = (12000 + 16)/2 = 6008

Tolerance = 12000 - 6008 = 5992

Therefore, the value absolute value inequality for the hearing of the elephant is mod(e - 6008) ≤ 5992.

Similarly,

The mouse can hear: 1000 ≤ e ≤ 91000

The avg hearing = (12000 + 91000)/2 = 46000

Tolerance = 46000 - 1000 = 45000

Hence, the value absolute value inequality for the hearing of the mouse is mod(m - 46000) ≤ 45000.

Answer: We can use the formula for the sum of an arithmetic series to find the number of pages in the Funny Book. The formula is:

S = n/2 (2a + (n-1)d)

Where S is the sum of the series, n is the number of terms, a is the first term, and d is the common difference.

In this case, the series is the page numbers, a = 1, d = 1, and we know that there is no page numbered "21" but the page numbered "20" is there.

The number of pages numbered 20 is 20, and the number of pages numbered 19 is 19. So n = 20 + 19 = 39

By substituting the values into the formula

S = 39/2 (2*1 + (39-1)1) = 3920 = 780

The greatest number of pages that the Funny Book can have if it contains a page numbered 20 but not any that are numbered 21 is 780.

The system of equations for this problem is defined by these two equations presented as follows:

The first equation can be simplified as follows:

y = 3x - 27 = 3(x - 9).

Hence, substituting y = 3(x - 9) into the second equation, the solution for x can be obtained as follows:

x - 3(x - 9)/3 = 9.

x - x + 9 = 9
