BY using the inequality,
(67 + 65 + 64 + 88 + 2x)/5 ≥ 73,
we find the score she must make on final exam to pass the courses with an average of 73 or higher is x>=80.
What is inequality?An inequality is a mathematical statement that shows that one quantity is greater than or less than another quantity.
What is average?The average, or mean, of a set of numbers is a measure of the central tendency of the set.
This inequality states that the average of Shureka's scores on the four tests and the final exam must be greater than or equal to 73 in order for her to pass the course. Solving for x, we find that x ≥ 80.
The meaning of the answer to part (a) is that Shureka must make a score of 80 or higher on the final exam in order to pass the course with an average of 73 or higher. In other words, if Shureka makes a score of 80 or higher on the final exam, her average score on the five tests will be 73 or higher, which is the minimum required to pass the course. If she makes a score lower than 80 on the final exam, her average score will be less than 73, and she will not pass the course.

2ox - 5y = 10
2x + 5y = 12
22x = 22 Divide both sides by 22
x = 1
Substiture in 1 for x in either of the two original equations
2x +5y = 12
2(1) + 5y = 12
2 + 5y = 12 Subtract 2 from both sides
5y = 10 Divide both sides by 5
y = 2

The sampling distribution refers to the distribution of the sample mean (X-bar) computed from a set of n independent, normal random variables (X1,...,Xn).
The sampling distribution is a theoretical distribution that describes how the sample mean would vary if you were to take multiple samples from the population and compute the sample mean for each sample. It is based on the assumption that the X1,...,Xn are independently and normally distributed with a common mean and variance.
The sampling distribution is important because it allows us to make inferences about the population mean based on the sample mean. By understanding the properties of the sampling distribution, we can calculate confidence intervals and perform hypothesis tests to determine whether the sample mean is significantly different from the population mean.
In contrast, the distribution on the individual random variables (X1,...,Xn) is the distribution of the individual observations in the sample. The distribution on the means of the individual random variables (Xi) is the distribution of the mean of each individual random variable.
The frequency distribution obtained from a set of n experimental data values is the distribution of the observed data values in the sample.

Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the three angles are x, y and z.
x+ y + z = 180............(E3)
The sum of the measures of the second and third angles is three times the measure of the first angle.
So, y+ z = 3x

If a sample consists of 600 test scores, 516 of them would be at or below the 86th percentile. If a sample consists of 600 test scores, 228 of them would be at or above the 62th percentile.
What is percentile?A percentile is a score that compares a specific score to the scores of the other members of a group. It displays the proportion of other scores that a given score outperformed. For instance, if you have a test score of 75 and are placed in the 85th percentile, it signifies that your score is greater than those of 85% of other test takers.
Given that,
In general, 70 % of the values in a data set lie at or below the 70th percentile.
20 % of the values in a data set lie at or above the 20th percentile.
Generally percentile defines the percentage of a data set that is below or at a value that is being considered.
Hence the percentage of the values of a data set that lies below or at the 16th percentile is 16%
Also the values of a data set that lies below or at the 24th percentile is 24%
Given a sample of 600 test scores , the number of test scores that will be at or below the 86th percentile is 86% of 600 which is mathematically represented as:
K = [tex]\frac{86}{100}[/tex] × 600
K = 516 test scores
Given a sample of 600 test scores , the number number of test scores that will be above the 62 th percentile is (100 - 62 = 38 )% of 600 which is mathematically represented as:
a = [tex]\frac{38}{100}[/tex] × 600

So, we have the following representation
y = -4x + 4
Also, from the question;
We have the following points
The point is given as
Point = (-1, -5) i.e. (x, y) = (-1, -5)
The equation of a line can be represented as
y = mx + c
Where
Slope = m
By comparing the equations, we have the following
m = -4
This means that the slope is -4
The slopes of parallel lines have the same values
This means that the slope of the other line is -4
The equation of the line is then calculated as
y = m(x - x₁) + y₁
Where
m = -4
(x₁, y₁) = (-1, -5)
So, we have
y = -4(x + 1) - 5

The expression 12x + 8 represents the preimeter of a square. Write 12x+ 8 as a product. Then tell what expressions represents one side of the square.
Answer:
(3+2)
Step-by-step explanation:
Perimeter of a square = 4L
L is the length of one side of the square
Given the expression 12 + 8 that represents the perimeter of a square, factoring out 4 from both terms;
12 + 8
= (4*3)+(4*2)
= 4(3+2)
Comparing with 4L
4L = 4(3+2)
Divide both sides by 4
4L/4 = 4(3+2)/4
L = (3+2)
Hence the expression that represents one side of the square is (3+2).
Hope this helps!!! :)

A linear function would best fit the data because as x increases, the y values change by an approximate constant. The rate of change of this function is approximately 8950 people a year.
How to classify a function as linear or exponential?To classify a function as linear or exponential, we have to check whether the differences or the quotients between consecutive terms are constant, as follows:
Constant differences -> Linear function.Constant quotient -> Exponential functions.The differences for the consecutive terms in the table are given as follows:
75,232 - 66,237 = 8,995.66,237 - 57,332 = 8,905.57,332 - 48,391 = 8,941.The ratios for the table are given as follows:
77,252/66,237 = 1.166.66,237/57,332 = 1.155.57,332/48,391 = 1.185.The differences have less variation then the ratios, then a linear function best models this data, with an slope of approximately (8995 + 8905 + 8941)/3 = 8947, which is the mean of these differences.
(rounded to 8950).

Find how long it takes $2500 to double if it is invested at 6% interest compounded semiannually. Use the formula A=P(1+r/n) to solve the compound interest problem.
It will take approximately years.
(Do not round until the final answer. Then round to the nearest tenth as needed.)
The total years taken to double the money according to Compounding will be 12.5 years.
What is compound interest?
Compound interest is that the interest on savings calculated on each the initial principal and therefore the accumulated interest from previous periods.
Main body:
Given :
rate = 6%
amount = $2500
Total amount = $5000
Compounded semi -anually,
so formula becomes,
Total amount = amount (1+r/200)^2t
T = [tex]A (1+\frac{r/2}{100})^{2t}[/tex])
5000 = 2500 (1+3/100)^2t
2 = [tex](1+0.03)^{2t}[/tex]
2 = [tex]1.03^{2t}[/tex]
taking log on both sides
log 2 = 2t *log 1.03
0.3/0.012 = 2t
t = 12.5 years
Hence the time taken to double the money is 12.5 years.
