In this case, the proportion (79%) only applies to the sample of 481 consumers and thus it is a statistic because it represents the sample.

The distinction between a parameter and a statistic is that a parameter refers to a sample property, but a statistic is referred to as a population distribution characteristic.

For instance, a population mean is a parameter, but a sample mean is a statistic.

Although we can use it to draw conclusions about the population, in this case, the proportion (79%) only applies to the sample of 481 consumers and is thus only a statistic.

Step-by-step explanation:

The number of distinct prime factors are 17

The term prime factors in math is defined as a method to find the prime factors of a given number and it can be said a composite number.

As per the definition of prime factor here we have know that a and b have 7 prime factors in common.

Then it can be written as a*b has 28 prime factors

And here we also know that the number of prime factors of a or b that are not common to both is 21

Here we have also know that a has less prime factors than b so at most 10 of these 21 extra prime factors belong to a

Then the  the most prime factors that  a  can have is calculated as

The probability of getting exactly 8 girls out of 11 births is 21.9%.

The binomial probability formula is used to calculate the probability of getting a certain number of successes (in this case, girls) out of a fixed number of trials (in this case, 11 births).

The first part of the formula (11 choose 8) is the number of ways to choose 8 girls out of 11 births, which is 330.

i.e;    (11 choose 8) * (0.5)^8 * (0.5)^3 = 330

The second part of the formula (0.5)^8 represents the probability of getting 8 girls out of 11 births assuming each birth has a probability of 0.5 of being a girl.

The third part of the formula (0.5)^3 represents the probability of getting 3 boys out of 11 births assuming each birth has a probability of 0.5 of being a boy.

i.e; (11 choose 8) * (0.5)^8 * (0.5)^3 = 330 * 0.00390625 * 0.125 = 0.21875

When we multiply all of these values together we get the final probability of getting exactly 8 girls out of 11 births, which is approximately 0.21875 or about 21.9%.

Therefore, the probability of getting exactly 8 girls out of 11 births is given by the binomial probability formula: (11 choose 8) * (0.5)^8 * (0.5)^3 = 330 * 0.00390625 * 0.125 = 0.21875 or about 21.9%.

Answer: The function that models the relationship between the number of games played (n) and the number of credits remaining on the card (C(n)) is C(n) = 5n.

Step-by-step explanation: This function can be derived by realizing that each game costs 5 credits to play, so as the number of games played (n) increases, the number of credits remaining on the card (C(n)) decreases by 5 for each game played.

For example, if Shivani played 16 games before her card ran out of credits, we can substitute n = 16 into the function to find that C(16) = 5(16) = 80 credits. This means that her card had 80 credits on it before she started playing games.

To plot points on the graph, we can select a few different values of n and substitute them into the function to find the corresponding values of C(n). Here are a few examples:

When n = 0, C(n) = 5(0) = 0. This represents the case when Shivani has not played any games yet and has no remaining credits on her card.

When n = 8, C(n) = 5(8) = 40. This represents the case when Shivani has played 8 games and has 40 credits remaining on her card.

When n = 16, C(n) = 5(16) = 80. This represents the case when Shivani has played 16 games and her card has no remaining credits.

We can plot these points on the graph and label them (0,0), (8,40), (16,0) respectively.

Note that the y-intercept is (0,0) and the x-intercept is (16,0)

Graph:

n C(n)

0 0

8 40

16 0

The graph is a straight line starting from (0,0) and going down till (16,0) with a slope of -5.

What is the right triangle?

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle, i.e. two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle.

Given that the angles of a triangle are 30-60-90.

The smallest angle is always opposite the shortest side, and vice versa. The longest side is also opposite the largest angle, and vice versa.

The opposite side of angle 30 is the shortest side of the triangle.

The opposite side of angle 90 is the longest side of the triangle.

Sine law:

a/sin A = b/ sin B =c/sin C

a is the opposite side of angle A, b is the opposite side of angle B, c is the opposite side of angle C.

Assume that the length of the longest side is a.

Applying sine law in the given triangle:

6√10/sin 30 = a/sin 90

6√10/(1/2)= a/1

a = 12√10

Step-by-step explanation:

Given expression:

[tex]\left[2-\left|-\dfrac{1}{4}-2\left(-\dfrac{3}{5}\right)\right|\right] \div (-6)[/tex]

Carry out the operations inside the absolute value bars (following the order of operations):

[tex]\implies \left[2-\left|-\dfrac{1}{4}+\dfrac{6}{5}\right|\right] \div (-6)[/tex]

[tex]\implies \left[2-\left|\dfrac{19}{20}\right|\right] \div (-6)[/tex]

As the fraction inside the absolute value bars is already positive, we can simply remove the bars:

[tex]\implies \left[2-\dfrac{19}{20}\right] \div (-6)[/tex]

Rewrite 2 as 40/20 and carry out the subtraction inside the square brackets:

[tex]\implies \left[\dfrac{40}{20}-\dfrac{19}{20}\right] \div (-6)[/tex]

[tex]\implies \left[\dfrac{40-19}{20}\right] \div (-6)[/tex]

[tex]\implies \left[\dfrac{21}{20}\right] \div (-6)[/tex]

Rewrite -6 as a fraction:

[tex]\implies \dfrac{21}{20} \div -\dfrac{6}{1}[/tex]

When dividing fractions, multiply the first fraction by the reciprocal of the  second fraction:

[tex]\implies \dfrac{21}{20} \times-\dfrac{1}{6}[/tex]

[tex]\implies \dfrac{21 \times (-1)}{20 \times 6}[/tex]

[tex]\implies -\dfrac{21}{120}[/tex]

Reduce the fraction to its simplest form by dividing the numerator and denominator by the highest common factor, 3:

Compared to a 95% confidence interval, a 99% confidence interval will be wider.

A confidence interval is a range of values that is likely to contain the true population mean, with a certain level of confidence.

The level of confidence is usually represented as a percentage, such as 95% or 99%. The higher the level of confidence, the wider the confidence interval will be. This is because a higher level of confidence means that the researcher wants to be more certain that the true population mean falls within the interval, so they will make the interval wider to increase the chances of this happening.

Answer: Vera's starting salary at the company was $53600.

Step-by-step explanation:

We can start by using the following proportion:

(Current salary) / (Starting salary) = (Percent increase) / 100

So we can write:

67,000 / Starting salary = 125 / 100

To find the starting salary we can cross-multiply and divide:

67,000 = (125 * Starting salary) / 100

67,000 * 100 = 125 * Starting salary

67,000 * 100 = 125 * Starting salary

67,000,000 = 125 * Starting salary

Starting salary = 67,000,000 / 125

The area of the rectangle ABEF = 2sa = 2ss/(2*tan(180/8)) = s^2/(tan(180/8)).

What is an octagon?

An octagon is a polygon with eight straight sides and eight angles. It is a closed two-dimensional shape with eight sides of equal length. A regular octagon is an octagon in which all sides and angles are equal.

When it comes to the area of a regular octagon, the area of a regular polygon can be calculated using the formula

A = (ns^2)/(4tan(180/n)) where A is the area, n is the number of sides and s is the length of each side.

In case of a regular octagon, the area of an octagon is (8s^2)/(4tan(180/8))

A rectangle ABEF is made up of two congruent sides with the length of the side of the octagon, and two congruent sides with the length of the apothem of the octagon.

An apothem of a regular polygon is the distance from the center of the polygon to the midpoint of any side. The apothem of a regular octagon can be calculated by using the formula

a = s/(2*tan(180/8)) where a is the apothem and s is the side of the octagon.

Hence, the area of the rectangle ABEF = 2sa = 2ss/(2*tan(180/8)) = s^2/(tan(180/8)).

An altitude of a triangle is a line segment that extends perpendicularly from one of its vertices to the side opposite that vertex. A triangle with an angle larger than 90° is said to have an obtuse angle. The heights of the vertices of the acute angles of an obtuse triangle reside outside of the triangle due to the way the triangle is constructed.
