The area of figure is 272.52 square units.

The given figure consist:

A parallelogram of,

length = 12

width   = 18

Since we know that,

Area of parallelogram  = length x width

                                      = 12 x 18

                                      = 216 square units

And it consist of a semicircle of,

radius = 12/2

          = 6

Since we know that,

Area of semicircle is = πr²/2

                                  = 3.14 x 6 x 6/2

                                  = 56.52 square units

Thus,

The area of figure is sum of both areas,

⇒ 216 + 56.52

Hence, area is

⇒ 272.52 square units

the sample space of two-digit numbers using the digits 9, 4, 5, and 8 consists of 16 possible outcomes, and we can list all these outcomes in a table as shown above.

How to solve the question?

To create a sample space of two-digit numbers using the digits 9, 4, 5, and 8, we need to consider all possible combinations of these digits. We can list all possible outcomes in a table where each digit represents a column and each combination represents a row.

The first digit can be any of the four digits, and the second digit can also be any of the four digits, including the same digit as the first. Therefore, the total number of outcomes is 4 x 4 = 16.

Here is the sample space of two-digit numbers using the digits 9, 4, 5, and 8:

         9    4   5     8

9 99 94 95 98

4 49 44 45 48

5 59 54 55 58

8 89 84 85 88

As shown in the table, the first digit can be any of the four digits, and the second digit can also be any of the four digits. For example, the first row shows that the possible two-digit numbers starting with 9 are 99, 94, 95, and 98. Similarly, the second row shows that the possible two-digit numbers starting with 4 are 49, 44, 45, and 48, and so on.

In conclusion, the sample space of two-digit numbers using the digits 9, 4, 5, and 8 consists of 16 possible outcomes, and we can list all these outcomes in a table as shown above.

Answer:

I think it would be written like this: 11-(5*k)

Step-by-step explanation:

The main answer is that the infinite number of types of matter arises from the unique combinations of elements and their arrangements in terms of composition and geometry.

While the number of elements is limited, their combinations and arrangements allow for an infinite number of types of matter. Elements can combine in different ratios and configurations, forming various compounds and structures with distinct properties.

Additionally, the arrangement of atoms within a molecule or the spatial arrangement of molecules within a material can create different types of matter. These factors, along with the possibility of isotopes and different states of matter, contribute to the vast diversity and infinite types of matter despite the limited number of elements.

The equation of the line in form y=mx+c is y = -3x + 1 and y = 2x - 1

We can find the equation of the line using the values of x and y

We know that for a straight line

m = y₂ -y₁/x₂-x₁

Let us take values x = -4, y= 17 and x= -3 y =13.

m = 17-13/ -4+3

m = -4

Now putting the value in the equation of the line.

y =mx + c

17 = (-4). -4 + c

17 = 16 + c

c = 1

Hence the equation of the line

y = -3x + 1

We know that for a straight line

m = y₂ -y₁/x₂-x₁

Let us take values x = -4, y= 17 and x= -3 y =13.

m = -5 +1 / -2-0

m = 2

Now putting the value in the equation of line.

y =mx + c

-5 = (2). -2 + c

-5 = -4 + c

c = -1

Compute for the sum of the given numbers in each set.

Divide the sum computed in step 1 by the total number of values in each set (count the values).

The resulting quotient is the mean of the respective set of numbers.

A. Computing for the Mean of a Sample

Given Mean 3, 4, 9, 11, 5

To find the mean of the given set, we need to compute the sum first.

Answer:

Step-by-step explanation:

1) if Peter's sum is p and Jacky's is j, then the ratio 5:2 in the condition can be written j/p=5/2;

2) the phrase 'after Jacky gave 15 dolls to Peter, they have an equal number of dolls' can be written as j-15=p;

3) using the two above it is possible to make up the system of two equations:

\(\left \{ {{\frac{j}{p} =5/2} \atop {j-15=p}} \right. \ = > \ \left \{ {{j=2.5p} \atop {j-15=p}} \right. \ = > \ \left \{ {{j=25} \atop {p=10}} \right.\)

4) finally, the have together 10+25=35 doll-s.

Jacky and Peter had a total of 70 dolls altogether.

A equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the number of Jack doll and y represent Peter doll, hence:

x - 15 = y + 15  (1)

Also:

(5/7)(x + y) = x   (2)

From both equations:

x = 50, y = 20

The correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

To calculate the probability of a cash flow being between $16,000 and $19,000, we can use the standard deviation and assume a normal distribution.

We are given that the average cash flow is $14,000 with a standard deviation of $5,000. These values are necessary to calculate the probability.

The probability of a cash flow falling within a certain range can be determined by converting the values to z-scores, which represent the number of standard deviations away from the mean.

First, we calculate the z-score for $16,000 using the formula: z = (x - μ) / σ, where x is the cash flow value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get z1 = (16,000 - 14,000) / 5,000.

z1 = 2,000 / 5,000 = 0.4.

Next, we calculate the z-score for $19,000: z2 = (19,000 - 14,000) / 5,000.

z2 = 5,000 / 5,000 = 1.

Now that we have the z-scores, we can use a standard normal distribution table or calculator to find the corresponding probabilities.

Subtracting the probability corresponding to the lower z-score from the probability corresponding to the higher z-score will give us the probability of the cash flow falling between $16,000 and $19,000.

Looking up the z-scores in a standard normal distribution table or using a calculator, we find the probability for z1 is 0.6554 and the probability for z2 is 0.8413.

Therefore, the probability of the cash flow being between $16,000 and $19,000 is 0.8413 - 0.6554 = 0.1859, which is approximately 18.59%.

So, the correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

The given statement "Lambda and r are related; specifically the natural log of lambda is equal to r." is False because lambda and r are not necessarily related in such a way.

Lambda and r are both parameters that can be used to model exponential decay or growth, but they have different interpretations and units of measurement.

Lambda, denoted as λ, is the decay constant or the rate at which a quantity decreases over time in an exponential decay model. It has units of inverse time (e.g., per second, per year). The natural logarithm of λ is not equal to r, but rather to the negative of the decay rate: ln(λ) = -k, where k is the decay rate.

On the other hand, r is the growth rate or the rate at which a quantity increases over time in an exponential growth model. It has units of inverse time (e.g., per second, per year) like lambda. The natural logarithm of the base of the exponential growth function is equal to r: ln(b) = r, where b is the base of the exponential function.

Answer:

1. x = 2.6

2. 7x + 1

Step-by-step explanation:

1. If 4.75x = 12.35, what is the value of x?

The equation is 4.75x = 12.35

The value of x can be determined by dividing both sides of the equation by 4.75

4.75x / 4.75 = 12.35 / 4.75

x = 2.6

2. What is 3x + 2 + 4x - 1 after combining like terms

Combining terms with variable x and constant terms (without any variable)

3x + 2 + 4x - 1

3x + 4x + 2 - 1

7x + 1

Answer:

See below.

Step-by-step explanation:

A. The angles 7 & 8 are vertically oppostie angles (V.O.A) & since they share the same vertex caused by the intersection of lines C & D, they'll have the same angle too.

B. Special angles caused by the intersection of lines C & D will have the same value as they are V.O.As & share the same vertex. Hence, to solve for y, the equation will be =》 5y - 29 = 3y + 19

C. Solving for y,

5y - 29 = 3y + 19

5y - 3y = 19 + 29

2y = 48

y = 48/2

y = 24

Since, angle 7 & 5y - 29 are linear pairs,

angle 7 = 180 - (5(24) - 29)

angle 7 = 180 - (120 - 29)

angle 7 = 180 - 91

angle 7 = 89°

Similarly, angle 8 & 3y + 19 are linear pairs,

angle 8 = 180 - (3(24) + 19)

angle 8 = 180 - (72 + 19)

angle 8 = 180 - (91)

angle 8 = 89°

•°• Hence, we also proved that angle 8 & 7 are V.O.As.

The whole = The total number of responses for the competition = 48

The percentage = 78% = The part/(The whole) × 100

The part = The missing information

To find the part, we substitute the values of the whole, and the percentage into the given following equation
