Answer:

k = -2

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

3.2k - 4.3 = 12.6k + 14.5

Step 2: Subtract 3.2k on both sides

-4.3 = 9.4k + 14.5

Step 3: Subtract 14.5 on both sides

-18.8 = 9.4k

Step 4: Divide both sides by 9.4

k = -2

Percentage change = 10%

We can use the formula:

Percent change = \(\frac{New-Old}{Old}\) x 100

Percent change = \(\frac{77-70}{70}\)x100

Percent change = \(\frac{7}{70}\) x 100

Percent change = 0.1 x 100

Percent change = 10%

Step-by-step explanation:

An inequality that represents Alicia’s possible age is x < 8.

For given question,

let x represent Alicia's age.

Amy is eight years older than twice her cousin Alicia’s age.

So, Amy's age would be 2x + 8

The sum of their ages is less than 32.

We write above statement in mathematical expression.

sum of their ages = (2x + 8) + x

                             = 3x + 8

The sum of their ages is less than 32.

We use the symbol < for 'less than'

So, the mathematical expression form of given statement would be,

(3x + 8) < 32

So, we get an inequality 3x + 8 < 32

⇒ 3x < 32 - 8

⇒ 3x < 24

⇒ x < 24/3

⇒ x < 8

Therefore, an inequality that represents Alicia’s possible age is x < 8.

The polygon shape that possesses the bigger area from the two given is: Hexagon

Polygons are defined as closed shapes that are two-dimensional. They possess straight sides and have the same number of sides as they have angles. Polygons have names that relate to how many sides they have.

A hexagon has more sides than a pentagon.

A hexagon is a polygon that has six sides and a pentagon is a polygon that has five sides.

Now, the more sides the polygon has, the more area it covers inside the circle as it will obviously be wider.

Thus, we can infer that the hexagon will have a bigger area.

Mu X is a statistical concept used to measure the difference between two means.

It is calculated by subtracting the mean of one group from the mean of another group. Mu X is often used to compare the means of two or more groups, or to compare the means of two subgroups within a group. It can also be used to measure the relative size of a group's mean compared to the grand mean or the size of a group's mean compared to the mean of another group. Mu X is a useful tool for distinguishing between true and false differences between two means. It is also useful for understanding the relative importance of different factors in a study. Mu X is sometimes referred to as the difference in means or the mean difference, and it is an important concept in inferential statistics.

Answer:

Step-by-step explanation:

The slope-intercept form of an equation for the line of fit shown in the scatter plot is; C. y=1.13x-2233.63

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

We can observe that the line of best fit on this scatters plot passes through points (1997, 13) and (2005, 22).

Using the slope formula,

⇒ slope = (22 - 13)/(2005 - 1997)

⇒ slope = (9)/8

Also, the slope-intercept form of an equation for the line of fit shown in the scatter plot is;

y - 13 = (9)/8(x - 1997)

y = 1.13x  -2233.63

Therefore, the slope-intercept form of an equation is y = 1.13x  -2233.63

Step-by-step explanation:

make sure to line up the decimal to each other to make sure the decimal is in the right place

The initial pressure of N2 and H2 gas in the vessel before being heated (before the reaction) is approximately 1.1864 atm.

The initial pressure of the N2 and H2 gas in the vessel can be calculated using the ideal gas law equation, which is:

PV = nRT

Where:

P is the pressure in atm V is the volume in liters n is the number of moles

R is the ideal gas constant (0.0821 L·atm/mol·K)

T is the temperature in Kelvin

To find the initial pressure of N2 and H2 gas, we need to calculate the total number of moles of gas present in the vessel.

Volume (V) = 25.0 L

Moles of N2 (n1) = 25.0 mol

Moles of H2 (n2) = 35.0 mol

Temperature (T) = 298 K

First, we need to calculate the total number of moles of gas present in the vessel:

Total moles of gas (ntotal) = moles of N2 + moles of H2

ntotal = n1 + n2

ntotal = 25.0 mol + 35.0 mol

ntotal = 60.0 mol

Next, we can substitute the values into the ideal gas law equation to calculate the initial pressure (P)

: PV = nRT P * V = n * R * T

P = (n * R * T) / V

Substituting the given values: P = (60.0 mol * 0.0821 L·atm/mol·K * 298 K) / 25.0 L

Now, we can calculate the initial pressure: P = 1.1864 atm

Therefore, the initial pressure of N2 and H2 gas in the vessel before being heated (before the reaction) is approximately 1.1864 atm. Please note that the answer may vary depending on the number of significant figures used during calculations.

The probability that the mean lifespan from the sample of 999 houseflies  is less than 242424 days is almost zero

Standardize the sample mean lifespan and find the corresponding probability using the standard normal distribution.

The formula for the standardized sample mean is:

z = (X - μ) / (σ / √n)

Where:

X = sample mean lifespan = 242424 days

μ = population mean lifespan = 262626 days

σ = population standard deviation = 121212 days

n = sample size = 999

Substituting the values in the formula, we get:

z = (242424 - 262626) / (121212 / √999) ≈ -10.33

The corresponding probability can be found using a standard normal distribution table or calculator. Alternatively, we can use the formula:

P(z < -10.33) ≈ 0

This means that the probability of obtaining a sample mean lifespan of 242424 days or less, assuming a population mean of 262626 days and a population standard deviation of 121212 days, is extremely low (almost 0).

The index of openness is a metric that measures the ratio of a country's total trade (exports plus imports) to its gross domestic product (GDP).

It is a measure of how much a country is open to international trade. If country X has imports valued at $2.9 trillion, exports valued at $1.5 trillion, and GDP valued at $9.8 trillion, the index of openness for country X can be calculated as follows: Index of openness = (Imports + Exports) / GDP Substituting the values for country X.

We get: Index of openness = ($2.9 trillion + $1.5 trillion) / $9.8 trillion Index of openness = $4.4 trillion / $9.8 trillion Index of openness = 0.45Therefore, the index of openness for country X is 0.45 when rounded to two decimal places.

We want to find the value of k given that the area of the region R is 36. To do this, we need to find the limits of integration and set up the integral for finding the area of the region R. The answer is (B) 3.

Since R is in the fourth quadrant and is enclosed by the x-axis and the curve Y = X^2 - 2KX, we can find the limits of integration by setting Y = 0 and solving for X:

0 = X^2 - 2KX
X(X - 2K) = 0
X = 0 or X = 2K

So the limits of integration are from X = 0 to X = 2K.

Now we can set up the integral for finding the area of the region R:

∫[0,2K] (X^2 - 2KX) dX

Integrating this expression gives:

[(1/3)X^3 - KX^2] evaluated at 0 and 2K

Plugging in the limits of integration and simplifying, we get:

(8/3)K^3 - 4K^3

Simplifying this expression, we get:

(2/3)K^3 = 36

Solving for K, we get:

K^3 = 54

Taking the cube root of both sides, we get:

K = 3

Therefore, the answer is (B) 3.

To find the value of k, follow these steps:

1. Determine the x-intercepts of the curve Y = X^2 - 2KX by setting Y = 0.
0 = X^2 - 2KX
X(X - 2K) = 0
The x-intercepts are X = 0 and X = 2K.

2. As we are looking for the area in the fourth quadrant, the integral bounds are from 0 to 2K.

3. Set up the integral for the area:
Area = ∫(X^2 - 2KX) dx, from 0 to 2K

4. Evaluate the integral:
Area = (X^3/3 - KX^2) | from 0 to 2K
= [(8K^3/3 - 4K^3) - (0)]
= 8K^3/3 - 4K^3
= (4K^3/3)

5. Set the area equal to 36 and solve for k:
36 = (4K^3/3)
9 = K^3
k = 3^(1/3) ≈ 2.08

The closest value from the given options is (A) 2.
