The probability distribution for X is given below:

Probability of no even number, (X = 0)= 1/2

Probability of one even number, (X = 1) = 1/2

Probability of two even numbers, (X = 2) = 1/8

The probability distribution for X is found as follows:

The probability that an even number is not selected i.e. X = O

P(X = 0) =  (2/4 * 2/4) + (2/4 * 2/4)

P(X = 0) = 1/2

The probability that an even number is selected once i.e. X = 1

P(X = 1) =  (2/4 * 2/4) + (2/4 * 2/4)

P(X = 1) = 1/2

The probability that an even number is selected twice i.e. X = 2

P(X = 2) = 2/4 * 2/4

P(X = 2) = 1/8

In the equation c + a = d + r, a = d + r - c

An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.

Given the equation in the question:

c + a = d + r

To solve for a in the equation c + a = d + r, we need to isolate a on one side of the equation by performing the same operation on both sides of the equation.

c + a = d + r

First, we can simplify the right side of the equation by subtracting c from both sides of the equation:

c + a = d + r

c + a - c  = d + r - c

Simplify

a + c - c  = d + r - c

a = d + r - c

Therefore, the solving for a as the subject of the formula is a = d + r - c.

Answer: The slope of the ramp is defined as the rise over the run, where the rise is the height of the step (2 feet) and the run is the horizontal distance from the bottom of the ramp to the step (7.0 feet). However, since the ramp is not straight but inclined, we need to use the length of the ramp (7.3 feet) to calculate the actual horizontal distance it covers.

Therefore, the run of the ramp is the square root of the difference between the length of the ramp squared and the height of the step squared:

run = sqrt(7.3^2 - 2^2) = sqrt(52.29 - 4) = sqrt(48.29) ≈ 6.95 feet

Now we can calculate the slope of the ramp:

slope = rise / run = 2 / 6.95 = 0.2885 ≈ 2/7

Therefore, the slope of the ramp is approximately 2/7.

The media personality's argument is flawed because they are basing their conclusion on a single year's data and ignoring the overall trend of increasing global temperatures. To counter this argument, one can make the following points:

1. While it is true that the annual increase in temperature may be less than the margin of error, the trend of increasing temperatures over several decades cannot be ignored. The margin of error is a statistical concept that takes into account the uncertainty in the measurement, but it does not negate the overall trend.

2. Global temperature records show that the Earth's temperature has been steadily rising over the past century, with the 10 warmest years on record occurring since 2005. This trend cannot be explained by natural variability alone and is consistent with the effects of human-caused climate change.

3. The consequences of rising global temperatures, such as melting glaciers, rising sea levels, and more frequent extreme weather events, are already being felt around the world. Ignoring this trend could have devastating consequences for future generations.

In summary, the media personality's argument is based on a flawed understanding of statistics and ignores the overall trend of increasing global temperatures. The best counterargument is to highlight the overwhelming evidence of climate change and its potential consequences.

Answer: this is hard

Step-by-step explanation:

The complete table for the time it takes to empty the barrel for the given rates is attached below. The value of constant k is 60.

To solve the problem, we can use the formula for inverse variation

time = k/leaking rate

where k is a constant of proportionality. We can find k by using the information given in the problem

30 = k/2

Solving for k, we get:

k = 60

Now we can use this value of k to fill in the table

Leaking rate (gallons per minute)                Time to empty (minutes)

      2                                                                           30

      1                                                                            60

      0.5                                                                        120

      0.25                                                                     240

      0.1                                                                        600

As the leaking rate decreases, the time to empty the barrel increases, because the liquid is leaking out more slowly.

The equation of each of the line are as follows;

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

Since the equation of this line is parallel to the line x + 2y = 4, the slope is given by;

Slope, m = -0.5

y - y₁ = m(x - x₁)

y + 3.5 = -0.5(x - 1)

y = -0.5x - 3

Since the equation of this line is perpendicular to the line 5x + 2y + 2 = 0, the slope is given by;

Slope, m = -5/2

m₁ × m₂ = -1

-5/2 × m₂ = -1

Slope, m₂ = 2/5

y - y₁ = m(x - x₁)

y - 2 = 2/5(x + 5)

y = 2x/5 + 4

Since the equation of this line passes through the origin (0, 0) and parallel to the line 4x - 5y = 10, the slope is given by;

Slope, m = 4/5

y - y₁ = m(x - x₁)

y - 0 = 4/5(x - 0)

Since the equation of this line is perpendicular to the line 3x - y = 4 and cuts the x-axis at -1, the slope is given by;

Slope, m = 3

m₁ × m₂ = -1

3 × m₂ = -1

Slope, m₂ = -1/3

y - y₁ = m(x - x₁)

y - 0 = -1/3(x + 1)

y = -1/3(x) - 1/3

Since the line is perpendicular to the y-axis and passes through the point (-3, 5), the equation is given by;

y = 5.

Answer:

The size depends on their dimensions

Answer:

C. Their size depends on their dimensions

Locations in space or on a 2D flat surface are called points. Consider a house's address or even longitude and latitude coordinates. These places have no width, length, or height. A point has no dimensions. There are infinitely few points. They only seem to have a size because without it, the locations of the points wouldn't be visible.

This is why choices A B and D can be ruled out. Only choice C is true.

Answer:

254.3 ft^2

Step-by-step explanation:

First, let’s find the area of the entire circle. The area for a circle is 3.14 * radius^2

3.14*18^2 = 1017.36

Now, notice how the angle marked is 90 degrees, that means that this section of the circle is 90/360 (360 is the angle of a circle), or 1/4 of a whole circle. Now we can multiply 1/4 by the area to find 1/4 of the whole circle.

1017.36*1/4 = 254.34

We can solve this inequality for x as follows:

3 - 3x ≤ 4x + 7

Subtract 4x from both sides:

3 - 7x ≤ 7

Subtract 3 from both sides:

-7x ≤ 4

Divide both sides by -7, remembering to reverse the inequality since we are dividing by a negative number:

x ≥ -4/7

Therefore, the solution to the inequality is:

x ≥ -4/7

The method that results in a random sample of the population is D) randomly selecting 100 residents paying real estate taxes, using the town's list of taxpayers and a random number generator.

A random sample is one in which each member of the population has an equal chance of being selected for the survey. Option D satisfies this requirement because it uses a random selection process and targets the specific population of interest (residents paying real estate taxes).

Option A does not result in a random sample because it only includes people who happen to enter Town Hall over the course of one month, which may not be representative of the entire population.

Option B only targets parents of soccer players and may not be representative of the entire population.

Option C also does not result in a random sample because it only includes people entering a specific supermarket on the east side of town, which may not be representative of the entire population.

Being Male and driving to work are independent events.

P(Drive | Male) = P(Drive)

Hence, Blank 1 is 'independent event' and Blank 2 is '='.

Probability of being male is,

P(Being male) = 0.54

Probability of driving to work is,

P(Driving to work) = 0.5

Probability of being male and driving to work is,

P(Being male and driving work) = 0.27

The volume of the prism in cubic inches is 4/9 cubic in if each cube in the prism measures 1/3 inch on one side.

Hence, the correct option is A.

If each cube in the prism measures 1/3 inch on one side, then the volume of one cube is (1/3)³ = 1/27 cubic inches.

To find the volume of the prism, we need to know how many cubes are in the prism. Let's assume the prism has dimensions of length L, width W, and height H, all measured in units of cubes. Then, the total number of cubes in the prism is L × W × H.

Therefore, the volume of the prism in cubic inches is

Volume = (L × W × H) × (1/27) cubic inches

From the given figure, we can find

L = 3 inch

W = 2 inch

H = 2 inch

Substitute the values in formula to find the volume

= (3 × 2 × 2) × (1/27) cubic inches

= 4/9 cubic inches

Hence, the correct option is A.

The surface area of the square pyramid using given dimensions is given by option a.  3,456m².

In the square pyramid,

Using Pythagoras theorem,

Height of the square pyramid is equal to,

In a right angled triangle,

Base = 18m

Hypotenuse = 30m

⇒ height =  24m

Dimensions of square pyramid are,

Base edge 'b' = 36m

height of the pyramid 'h' = 24m

Surface area of square Pyramid = b² + 2b√(b²/4) + h²

Substitute the values we have,

⇒Surface area of square Pyramid

= 36² + 2(36)√((36)²/4) + (24)²

Answer: (B)

Step-by-step explanation:

To determine which point is a solution to the system of inequalities, we must test each point to see if it satisfies both inequalities. Starting from point A, we plug in its coordinates (2, 9) into both inequalities. However, it does not satisfy y < 1 over 2x − 2. We then move on to point B, which has coordinates (3, 0). Plugging this into both inequalities, we find that it satisfies both of them. Therefore, the point that is a solution to the system of inequalities is point B.
