A series of terms is referred to as a geometric progression if each next term is produced by multiplying each previous term by a fixed amount. (GP), whereas the common ratio is the name given to the constant value. In the case of the GP 2, 4, 8, 16, 32, 64, for instance, the common ratio is 2.

The phrase that comes after the previous one in the GP, having a common ratio of r = l/[r(n-1)]. S=a/(1 - r), where 0 r 1, is the sum of infinite, or the sum of a GP with infinite terms.

A number progression is said to as a geometric progression if any two consecutive terms is always same.

Hence we have a=3,n=9,r=2

Now [tex]t=ar^n^-^![/tex]

=[tex]3*2^9^-^1[/tex]

=[tex]3*2^8[/tex]

=3×256

=768

∴ The ninth term of the G.P. is 768.

What are the arithmetic calculations?

Arithmetic is the branch of mathematics that deals with basic operations such as addition, subtraction, multiplication, and division, and their properties and applications. Arithmetic calculations are mathematical operations that involve one or more numbers and result in a numerical answer. These operations can be performed using mental arithmetic, pencil, and paper, or with the help of a calculator.

Let the number be x. We can write the given expression as:

6(x - 2) = x - 42

Expanding the left side:

6x - 12 = x - 42

Solving for x:

5x = 30

x = 6

Therefore, the number is 6.

Answer:

After 100 days, the amount of the substance will decrease to half its original value, so Yo/2 = 5 mg. The half-life of a substance is the time it takes for half of it to decay or disappear. So, every 100 days, the amount of the substance will be halved until there is none left.

Question is not clear.

Let's call the number of words Trei spelled correctly "x". Then, the number of words she spelled incorrectly is 100 - 60 = 40 words.

Therefore, the ratio of correctly spelled words to incorrectly spelled words is x to 40.

To find the number of words she spelled correctly for each word she spelled wrong, we can simplify the ratio by dividing both values by the greatest common factor:

x / 40 = x / (2 * 20) = x / 2 * 20 / 2 = x / 20.

So for every word Trei spelled incorrectly, she spelled 20 / 1 = 20 words correctly.

(the tail points right on the number line), the mean is higher than the median.

What is median?

The value of the middle observation found after the data are arranged in ascending order is referred to as the median of the data. In many cases, it is challenging to take all of the facts into account when representing something, and in these cases, median is helpful. The median is one of the simples to compute statistical summary metrics. The median is also known as the place average since it uses the data that is in the center of a sequence to determine its value.

Every student learns one of the fundamental principles of statistics, which is that in a skewed distribution, the mean is closer to the tail, in around the second week of introductory statistics.

Every student learns one of the fundamental principles of statistics, which is that in a skewed distribution, the mean is closer to the tail, in around the second week of introduction to statistics. Therefore, the mean is greater than the median in a right-skewed distribution (where the tail points directly to the right on the number line).

Hence, (the tail points right on the number line), the mean is higher than the median.

Step-by-step explanation:

a) The probability that Stephen wins can be estimated by dividing the number of times he wins by the total number of matches:

P(Stephen wins) = 11/27 = 0.407 (or 40.7%)

b) The probability that Natasha wins can be estimated by subtracting the probability of Stephen winning from 1:

P(Natasha wins) = 1 - P(Stephen wins) = 1 - 0.407 = 0.593 (or 59.3%)

The correct form of the equation can be written as y = 35/6 x + 2

We have to know that the equation have been given to us in the point that we have as; y - 5/7 = 5x - 6/6. We would then have to multiply both sides with the LCM of the equations and then we have that;

42(y - 5/7) = 42(5x - 6)/6

6(y - 5) = 7(5x - 6)

6y - 30 = 35x - 42

Collecting the like terms we have that;

6y - 35 x = -42 + 30

6y - 35x = -12

6y = 35x + 12

y = 35/6 x + 12/6

y = 35/6 x + 2

The number of subsets for R { -15 , -13 , -11 , -9 , -7 , -5 , -3 , -1 } is given by the equation A = 255 subsets

The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

Let the relation set be represented as R

Now , the set R = { x|||xis an odd, negative integer and x>−16 }

The number of elements in the set R is given by

R = { -15 , -13 , -11 , -9 , -7 , -5 , -3 , -1 }

So , the number of elements n = 8 elements

The number of subsets of any arbitrary set  is equal to 2ⁿ

This means that the number of proper subsets (which is the number of subset minus the set itself, for finite subsets) is equal to 2ⁿ-1

So , the number of subsets for R = 2⁸ - 1 = 255 subsets

Hence , the solution set is  { -15 , -13 , -11 , -9 , -7 , -5 , -3 , -1 }
