A right skewed distribution means that the majority of the data falls to the left of the mean, with a long tail to the right. This can also be called a positive skew.

In this type of distribution, the median is typically less than the mean, and the mode is even smaller than the median. This type of distribution is common in data sets that have a lower bound but no upper bound, such as income or age.

The opposite of a right skewed distribution is a left skewed distribution, where the majority of the data falls to the right of the mean with a long tail to the left.

In a right-skewed distribution, the mean is typically greater than the median and the mode. This is because the mean is influenced by the values in the long tail on the right-hand side of the distribution, which pull the mean in that direction.

The median and mode, on the other hand, are less affected by the extreme values in the tail and are therefore more representative of the central tendency of the distribution.

Examples of right-skewed distributions include the distribution of income, where a few individuals have very high incomes that create a long tail on the right-hand side, and the distribution of test scores, where a few high-performing students may create a similar tail.

Right-skewed distributions are common in many natural and social phenomena, and understanding their properties is important for statistical analysis and modeling.

The sequence is an = 8(one half)n − 1, and the average rate of change from n = 1 to n = 3 is -3.

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
The sequence graphed below is a geometric sequence with the first term a1 = 8 and the common ratio r = 1/2. The sequence can be expressed as:

an = 8(1/2)^(n-1)

To find the average rate of change from n = 1 to n = 3, we need to calculate the difference between the third term and the first term, and then divide by 2 (since there are two terms between n = 1 and n = 3):

an = 8(1/2)ⁿ⁻¹

a₁ = 8(1/2)¹⁻¹ = 8

a₃ = 8(1/2)³⁻¹) = 2

Average rate of change from n = 1 to n = 3:

= (a₃ - a₁) / (3 - 1)

= (2 - 8) / 2

= -3

Therefore, the sequence is an = 8(one half)n − 1, and the average rate of change from n = 1 to n = 3 is -3.

Answer:

What is the distance between the two control stations on the earth's surface?

To find the distance between the two control stations, we can use the law of cosines. Let's call the distance between the control stations "d". Then, using the information that the angle of separation between the two stations is 10°:

d^2 = 2 * 3963^2 - 2 * 3963^2 * cos(10°)

d = sqrt(2 * 3963^2 - 2 * 3963^2 * cos(10°))

Using a calculator, we find that d = approximately 5657 miles. Rounding to the nearest whole number, the distance between the two control stations is 5657 miles.

What is the height of the satellite above the surface of the earth?

To find the height of the satellite, we can use the law of sines. Let's call the height of the satellite "h". Then, using the information that the distance between the two control stations is d:

h / sin(10°) = d / 2

h = d / 2 * sin(10°)

Using the value of d from the previous question, and a calculator, we find that h = approximately 22,795 miles. Rounding to the nearest whole number, the height of the satellite above the surface of the earth is 22,795 miles.

There are 50 calories per cup of popcorn and 16 per ounce of soda.

A solution to an equation is a number that can be substituted for the variable to provide a true number statement.

Let's represent x be the number of calories per cup of popcorn

And let's represent y be the number of calories per ounce of soda.

The two equations are based on the given details:

2x + 7y = 212 ....(i)

1x + 11y = 226 ....(ii)

From equation (ii), we have

x + 11y = 226

x = 226 - 11y

Substitute the value of x = 226 - 11y in equation (i), and solve for y:

y = 16

Substitute the value of y = 16 in equation (ii), and we get

x = 50

Step-by-step explanation:

Answer: y in terms of x is y = 5x + 5.

Step-by-step explanation:

Since the graph of y^3 against x is a straight line passing through the points (1,5) and (6,15), it means that y^3 can be modeled as a linear equation in terms of x.

Let's call the slope of the line m and the y-intercept b. We can find the values of m and b using the two points (1,5) and (6,15).

Using the point-slope form of a linear equation, we can write:

y - 5 = m(x - 1)

Substituting (6,15) into the equation:

15 - 5 = m(6 - 1)

So, m = 5.

Next, we can use the slope-intercept form of a linear equation to write y in terms of x:

y = mx + b

Substituting the values of m and b:

y = 5x + 5

So, y in terms of x is y = 5x + 5.

The angles m∠1and m∠2 can be classified as vertical angles, while the angles m∠3 and m∠4 is not a linear pair, neither are they vertical or adjacent angles.

Angles are classified as a linear pair if they are formed by the intersection of two lines making them a pair of adjacent angles.

Vertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.

Two angles are said to be adjacent when they share a common vertex and one common side. Two adjacent angles sum up to 180°.

From observation, angles m∠1and m∠2 can be classified as vertical angles as they are vertically opposite each other.

But angles m∠3 and m∠4 cannot be classified as any of the three defined classes of angles.

The height of the cylindrical concrete pillar is approximately 153.2 centimeters.

Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:

[tex]V = a\times b \times c \: \: unit^3[/tex]

We are given that;

Length of prism=8.8cm

Height=4.4cm

Volume=271.04 cubic centimeters.

Now,

We can use the formula for the volume of a cylinder to find the height of the pillar. The formula for the volume of a cylinder is:

V = πr^2h

where V is the volume, r is the radius, and h is the height.

First, we need to find the radius of the pillar. The diameter of the pillar is given as 10 centimeters, so the radius is half of that:

r = 10/2 = 5 centimeters

Now we can substitute the given volume and radius into the formula and solve for the height:

12,042 = π(5)^2h

Divide both sides by π(5)^2:

h = 12,042 / (π(5)^2)

h ≈ 153.2 centimeters (rounded to one decimal place)

Therefore, by the given volume the answer will be 153.2 centimeters.

Step-by-step explanation:

45×50/100 gives you the answer using BODMAS

There are 1000 cubic centimetres in a litre (cm3). This is so because one cubic centimetre (cc) equals one millilitre (ml), and one litre (l) equals 1000 ml.

1000 ml make up 1 litre (L).

ml (millilitres) = cm3

1000 ml = 1000 cm3

1 L = 1000 cm3

One litre is equal to one thousand cubic centimetres (cm3). This is because one cubic centimetre is equivalent to one millilitre (ml), and one litre is equal to 1000 millilitres (ml). The subsequent actions can be conducted in order to calculate this. Initially, one litre (L) equals one thousand millilitres (ml). Second, one cubic centimetre is equivalent to one millilitre (cm3). Thus, one millilitre is equivalent to one hundred cubic centimetres. Last but not least, one litre equals one thousand cubic centimetres, or 1 L = 1000 cm3. Anybody wishing to translate between the two different volume measures will find this information valuable. For instance, if a recipe calls for a certain amount of an ingredient in litres, it is simple to convert that amount to cubic centimetres if necessary.

If a first time homebuyer is given the choice of two loans: loan a: 390,000, 15 year-fixed, 4 discount points. The amount the hole buyer save in total by choosing loan is:  b) 11,427.

To compare the total cost of each loan, we need to calculate the total payments made over the life of the loan.

For loan A, the monthly payment is $3,509.71 and the loan term is 15 years, so the total payments would be:

Total payments = monthly payment x number of months

Total payments = $3,509.71 x (15 x 12)

Total payments = $631 747.8

However, loan A also has a 4-point discount, which means the borrower paid 4% of the loan amount upfront to reduce the interest rate.

Discount points = loan amount x discount rate

Discount points = $390,000 x 0.04

Discount points = $15,600

To calculate the total cost of loan A, we need to add the discount points to the total payments:

Total cost of loan A = total payments + discount points

Total cost of loan A = $631 747.80 + $15,600

Total cost of loan A = $647,347.80

For loan B, the monthly payment is $3,659.86 and the loan term is 15 years, so the total payments would be:

Total payments = monthly payment x number of months

Total payments = $3,659.86 x (15 x 12)

Total payments = $658,774.5

To calculate the total cost of loan B, we simply add the total payments:

Total cost of loan B = total payments

Total cost of loan B =  $658,774.5

Therefore, the total amount saved by choosing loan A over loan B is:

Savings = total cost of loan B - total cost of loan A

Savings = $658,774.5 - $647,347.80

Savings = $11,427
