Answer:

40.9 ft.

Step-by-step explanation:

We know all the side lengths needed:

8 + (10*2) + 8.9 +4 = 40.9

So then you just add them!

To divide the complex numbers (2 - 4i) by (5 - 7i), we can use the concept of multiplying by the conjugate of the denominator to simplify the expression.

The conjugate of the denominator (5 - 7i) is (5 + 7i). To simplify the division, we multiply both the numerator and denominator by the conjugate:

[(2 - 4i) * (5 + 7i)] / [(5 - 7i) * (5 + 7i)]

Expanding the numerator and denominator, we get:

[(10 + 14i - 20i - 28i^2)] / [(25 - 49i^2)]

Simplifying further, we have:

[(10 - 6i - 28i^2)] / [(25 + 49)]

Since i^2 is equal to -1, we can substitute -1 for i^2:

[(10 - 6i - 28(-1))] / [25 + 49]

Simplifying the expression, we get:

[(10 - 6i + 28)] / [74]

Combining like terms, we have:

(38 - 6i) / 74

Now, we can simplify the expression by dividing both the real and imaginary parts by 2:

38/74 - (6/74)i

In standard form, the result is:

19/37 - (3/37)i

Pilar needs to deposit $2841.68 at the end of each quarter at 4% per year compounded quarterly to obtain the required amount of $2500 in three years.

Calculate the Future Value of the Deposit

To calculate the amount Pilar needs to deposit each quarter, we will first need to calculate the future value of the deposit. The future value is the amount of money she will have at the end of the three years, which is $2500.

We can use the formula FV = PV × (1 + i)ⁿ, where FV is the future value, PV is the present value (in this case, the amount she is depositing each quarter), i is the interest rate (4% per year compounded quarterly), and n is the number of quarters (12 quarters in three years).

FV = 2500

2500 = PV × (1 + 0.04/4)¹²

Calculate the Present Value

To calculate the present value, we will need to rearrange the equation to solve for PV.

PV = 2500 / (1 + 0.04/4)¹²

PV = $236.84

Calculate the Total Amount to be Deposited

Finally, we can calculate the total amount Pilar needs to deposit each quarter by multiplying the present value by the number of quarters.

Total Amount = PV × n

Total Amount = 236.84 × 12

Total Amount = $2841.68

Pilar must therefore deposit $2841.68 at the end of each quarter at a rate of 4% annually compounded quarterly in order to reach the necessary $2500 in three years.

(a) Expected number of repairs per year is 0.33 (b) Standard deviation of number of repairs per year is 0.749, (c) The mean and standard deviation of annual expense are $136.55 and $26.217 respectively.

Standard deviation is a measure in statistics which measures the amount of deviation a set of data has with respect to their mean.

(a) Expected number of repairs for the freezer per year is the sum of the product of number of repairs to their probability.

E(Repairs) = (0 × 0.80) + (1 × 0.11) + (2 × 0.05) + (3 × 0.04)

                 = 0.33

(b) Standard deviation of number of repairs per year can be calculated as,

SD(Repairs) = \(\sqrt{[(0 - 0.33)^{2}(0.8)]+[(1-0.33)^{2}(0.11)] + [(2-0.33)^{2}(0.05)]+[(3-0.33)^{2}(0.04)] }\)

= √ (0.5611)

= 0.749

(c) Mean of the restaurant's annual expense with service contract is,

Mean = Expected cost = $125 + ($35 × 0.33) = $136.55

Standard deviation of the restaurant's annual expense with service contract is,

SD = \(\sqrt{35^{2}(0.5611) }\) = 35 × 0.759 = 26.217

Hence the expected number of repairs is 0.33, standard deviation of number of repairs is 0.749, mean and standard deviation of annual expense is $136.55 and $26.217 respectively.

The steps to condensing the expressions
2loga(4)+3loga(X-4)loga(4)

Log(x+3)+log(x-3) is given below.

To condense the   expressions, we can apply the  properties of logarithms. Here are the condensed forms of the given expressions.

2loga (4) + 3loga(X - 4) - loga 4 )  

By using the product and quotient rules of logarithms, we can simplify this expression as follows

2 loga( 4) + 3 loga( X-4) - log a(4)

= loga(4 ²) + loga((X-4)³) -  loga (4) = loga (16 ) + loga((X-4)³) - loga (4)

Combining the logarithms  using the power rule and quotient rule we have

= loga(16(X-4)³/4)

log(x+3) + log (x-3)

By using the product rule of logarithms, we can combine these logarithms

log (x +3) +log (x - 3) = log ((x +3 )(x -3 ))

Simplifying further, we get

= log (x² - 9 )

So this means that the condensed forms of the given expressions are

2loga( 4) + 3loga(X -4) - loga (4) = loga(16 (X-4) ³/4)

log (x+ 3) + log(x- 3) = log(x² - 9)

Babysitting Saves +$20/week

We are still needing $93 dollars to buy the pen, so, if she earns $20 peer week, then she should work:

$93 = 20 $/week * number of weeks

Calling x to the number of weeks and turning this into an inequality:

12 + 20x ≥ 105

Subtracting -12 to both sides:

20x ≥ 105-12

Simplifying:

20x ≥ 93

Step-by-step explanation:

The two stores at points A and C would serve the residents of Miniville, providing them access to essential goods and services, with residents in the middle mile having the flexibility to choose between the two stores.

If one store is located at point A and the other store is located at point C, it means that the stores are located at the extremes of the 3-mile stretch of Lake Shore Drive in Miniville. Point B would be the midpoint between points A and C.

Given that the 300 residents of Miniville are evenly distributed along the 3 miles of shoreline on the lake, it implies that there are approximately 100 residents per mile.

Therefore, the store located at point A would serve the residents living in the westernmost mile of Lake Shore Drive, while the store located at point C would serve the residents living in the easternmost mile of Lake Shore Drive.

The residents living in the middle mile, between points A and C, would have the option to shop at either store, depending on their preference or convenience.

Answer:

D is the correct answer

Step-by-step explanation:

After solving the system of equation we will get

x = 5y/2 +1  

y = 2/5- 2x/5

First equation is written

−2x+5y=−2

Subtract 5y from both sides.

−2x =−2−5y

The equation is in standard form.

−2x=−5y−2

Divide both sides by −2.

-2x/-2 = -5y-2/ -2

Dividing by −2 undoes the multiplication by −2.

x= −5y-2/-2

​Divide  −2−5y  by −2.

so

x= 5y/2 + 1

Now the second equation is

4x−10y=4

Add 4x to both sides

-10y = 4-4x

The equation is in standard form.

Divide both sides by 10

-10y/10= 4-4x/10

Dividing by 10 undoes the multiplication by 10.

y= 4-4x/10

Divide 4-4x by 10.

so

y= 2/5- 2x/5

Events A and C as well as events B and D are independent.

Two events A and B are independent if the occurrence or non-occurrence of one event does not affect the probability of the other event.

In the given events, it is not explicitly mentioned how the events are related. However, based on typical assumptions about burrito ingredients and customer preferences, we can make some assumptions:

Assuming that the choice of meat (chicken or carne asada) and the choice of beans (black beans or pinto beans) are independent of each other, we can conclude that events A (The burrito is a chicken burrito) and C (The customer requested black beans) are independent. The choice of chicken meat in the burrito does not affect the probability of the customer requesting black beans.

Similarly, events B (The burrito is a carne asada burrito) and D (The customer requested pinto beans) are independent. The choice of carne asada meat in the burrito does not affect the probability of the customer requesting pinto beans.

So, based on these assumptions, events A and C as well as events B and D are independent.

Answer:

The surface area of the sphere is approximately equal to 379.9 square centimetres.

Step-by-step explanation:

The surface are a of a sphere with respect to radius is 4πr².  We're given the diameter, of 11 cm, so we know that the radius is 5.5 cm.

With that we can find the surface area:

\(a = 4\pi r^2\\a = 4\pi (5.5cm)^2\\a = 4\pi \times 30.25cm^2\\a = \pi \times 121cm^2\\a \approx 3.14 \times 121cm^2\\a \approx 379.9cm^2\)

We can see that 7 is the total that is most likely to result, since it has the highest number of possible ways to roll it (6).


1) To find the probability of rolling a 10, we need to determine how many ways we can roll a 10 and then divide that by the total number of possible outcomes.

To roll a 10, we can get a 4 on one dice and a 6 on the other, or a 5 on one dice and a 5 on the other. So there are 2 ways to roll a 10.

The total number of possible outcomes is 6 x 6 = 36, since each dice has 6 possible outcomes.

Therefore, the probability of rolling a 10 is 2/36, which can be simplified to 1/18.

To find the probability of rolling higher than 10, we need to determine how many ways we can roll a total of 11, 12, or 13, and then divide that by the total number of possible outcomes.

To roll an 11, we can get a 5 on one dice and a 6 on the other, or a 6 on one dice and a 5 on the other. To roll a 12, we can get a 6 on both dice. To roll a 13, we can get a 6 on one dice and a 6 on the other.

So there are 4 ways to roll higher than 10.

Therefore, the probability of rolling higher than 10 is 4/36, which can be simplified to 1/9.

2) To find the probability of rolling an odd number, we need to determine how many ways we can roll an odd number and then divide that by the total number of possible outcomes.

To roll an odd number, we can get a 1, 3, or 5 on one dice and any number on the other dice, or we can get a 2, 4, or 6 on one dice and a 1, 3, or 5 on the other dice.

So there are 18 ways to roll an odd number.

Therefore, the probability of rolling an odd number is 18/36, which can be simplified to 1/2.

3) To find the total that is most likely to result, we need to determine which total has the most possible ways to roll it.

We can create a table to show how many ways we can roll each total:

Total | Number of Ways

2 | 1

3 | 2

4 | 3

5 | 4

6 | 5

7 | 6

8 | 5

9 | 4

The number of different towers with a height of 8 cubes can the child build with 2 red cubes, 3 blue cubes, and 4 green cubes is 312.

To solve this problem, we can use the formula for the number of ways to arrange n objects with k of one type, m of another type, etc. Specifically, the formula of combination  is:

(n-1)! / (k! * m! * ...)

In this case, we have 8 cubes total, with 2 red, 3 blue, and 4 green. So applying the formula, we get:

(8-1)! / (2! * 3! * 4!) = 7! / (2! * 3! * 4!)

= (7*6/2) * (5*4*3/6) * (4*3*2*1/24)

= 21 * 20 * 1

= 420

However, we have to remember that we are leaving out one cube. This means that for each tower we counted, there is actually a corresponding tower that is identical except for the color of the cube that was left out. So we need to divide by 3 (since there are 3 choices for which cube to leave out). This gives us:
