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.

Unsurprisingly, the general rule can be applied more broadly than the specific rule, which is the difference between the two. The specific rule is only applicable to dependent events; it applies to both independent and dependent events.

What is the main rule for multiplying?

Multiplication Rule The likelihood that both events A and B will occur if events A and B originate from the same sample space is equal to the probability that A will occur times the probability that B will occur provided that A has already occurred.

What is the rule for multiplying independent events?

The multiplication rule for independent events is the sixth rule of probability. P(A and B) = P(A) * P if A and B are two INDEPENDENT events (B).

                              P(A and B) = P(A) * P(B) is a special multiplication rule that is only applicable when the two occurrences are independent of one another. To put it another way, it only functions if the probability of one occurrence does not change for the other.

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.

Step-by-step explanation:

You want to identify an expression that can be factored by grouping.

This method of factoring involves grouping terms that have a common factor, then factoring that out. If the entire expression can be factored by grouping, then the result of this first round of factoring is expressions that also have a common factor.

One expression that can be factored by grouping is ...

  pr +ps +qr +qs

  = p(r +s) +q(r +s) . . . . . . . each pair of terms is factored

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].

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

Answer:

Step-by-step explanation:

a) Pour factoriser 3x + 6, vous devez trouver deux nombres qui ajoutés donnent 6 et qui multipliés donnent 3x. Les deux nombres sont 3 et 2, donc vous obtiendrez : 3x + 6 = 3(x + 2).

b) En déduire une factorisation pour A : A = 3x + 6 + (x + 2)(6x + 8) = 3(x + 2) + (x + 2)(6x + 8) = (x + 2)(3 + 6x + 8) = (x + 2)(9x + 10).

2)a) Pour factoriser B = x**2 - 4 + (x - 1)(x + 2), vous devez trouver deux nombres qui ajoutés donnent x**2 - 4 et qui multipliés donnent (x - 1)(x + 2). Les deux nombres sont x - 1 et x + 2, donc vous obtiendrez : x**2 - 4 + (x - 1)(x + 2) = (x - 1)(x + 2).

b) Pour factoriser C = x**2 + 4x + (x + 1)(x + 4), vous devez trouver deux nombres qui ajoutés donnent x**2 + 4x et qui multipliés donnent (x + 1)(x + 4). Les deux nombres sont x + 1 et x + 4, donc vous obtiendrez : x**2 + 4x + (x + 1)(x + 4) = (x + 1)(x + 4).

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.

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:

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

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.

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

Answer:

a. The area of the square is 25 feet x 25 feet = 625 square feet.

b. To find the percent of points that landed in the pond, we divide the number of points that landed in the pond by the total number of points generated and multiply by 100.

3,200 points / 5,000 points = 0.64

0.64 x 100 = 64%

so 64% of the points landed in the pond.

c. To find the area of the pond, we multiply the proportion of points that landed in the pond by the area of the square.

64% of the points landed in the pond = 0.64

Area of the pond = 0.64 x 625 square feet = 400 square feet. So, the area of the pond, to the nearest square foot, is 400 square feet.

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.
