The average change in sales income per month is $ 3 million.
What is average change and how is it assessed?
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function. A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.
Given, for 3 months, the average change in the company's sales
= $ 9 million
Also, for x months, the average change in the company's sales
= $ (9x/3) million
Therefore, for one month, the average change in the company's sales
= $ (9*1/3) million = $ 3 million
Thus, the average change in sales income per month is $ 3 million.

Based on the ratios of water consumed to the fruit juice consumed, the missing figures in the completed table would be:
24 water : 28 gallons of fruit juice 18 water : 21 gallons of fruit juice How to find the ratios?The ratio of water gallons consumed to fruit juice gallons is equivalent which means that at their simplest, they will always have the ratio of 6 : 7 as is the case in the 5th grade.
The missing ratio for Juice in 6th grade is:
= (Water gallons x Juice gallons in 5th grade) / water gallons in 5th grade
= (24 x 7) / 6

According to the factor theorem, if "a" is any real integer and "f(x)" is a polynomial of degree n larger than or equal to 1, then (x - a) is a factor of f(x) if f(a) = 0.Finding the polynomials' n roots and factoring them are two of their principal applications.
Calculate p(x(*r(x)?
The factorization of 62 + 17x + 5 by dividing the middle word can be used as an illustration of the factor theorem.In this example, two numbers, "p" and "q," can be discovered in such a way that p + q = 17 and pq = 6 x 5 = 30.One can then obtain the factors after that. A factor of | A | is (x - a) if each member of matrix A is a polynomial in x and | A | vanishes for x = a.When p(x) is divided by xc, the result is p if p(x) is a polynomial of degree 1 or higher and c is a real number (c).For some polynomial q, p(x)=(xc)q(x) if xc is a factor of polynomial p.Consequently, p(c)=(cc)q(c)=0, indicating that c is a polynomial zero.
I This theorem comes in very handy when we need to determine the determinant's value in "factors" form.

sat scores have a mean of 500 and standard deviation of 200. act scores have a mean of 20 and a standard deviation of 5. suppose that student a has an sat score of 600, and student b has an act score of 25. using z-scores, which student had a better college entrance exam score?
‘B’ had a better college entrance exam score due to the higher value of Z-Score.
The Z-score of an observation is the number of standard deviations it falls above or below the mean. Standard deviation is a statistic that is used to measure the dispersion of a dataset relative to its mean and is calculated by doing the square root of the variance.
[tex]Z=\frac{(observation-mean)}{standard deviation}[/tex]
By putting the values as given in the question,We get,
A's score is (600 - 500) / 200 = 0.5 standard deviation i.e. above the mean.
B's score is (25 - 20) / 5 = 1 standard deviations i.e. above the mean.

When the team plays at home, they win 83 % of their games.
When they play away from home, they win 26 % of their games.
find the probability the team wins with explanation
Based on the percentage of games played at home by the team, and the percentage win rate, the probability that the team wins is 63.05%
How to find the probability the team wins?First, find the probability that the team wins playing at home:
= Percentage win rate at home x Percentage played at home
= 83% x 65%
= 53.95%
Then find the probability of winning away:
= Percentage win rate away x Percentage played away
= 26% x (1 - 65%)
= 9.1%
The probability the team wins is:
= 53.95 + 9.1
= 63.05%
