Given the algebraic expression 3x⁴ - 5x + 2, each of following represents:

An algebraic expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables, numerical quantities (constants), accompanied with the use of different mathematical operations.

In Mathematics, a coefficient simply refers to a constant quantity or numerical value (number or numeral) that is typically placed before the variable in an algebraic expression.

In conclusion, an exponent is an operation that raises a numerical value or quantity to the power of another and it is generally written as bⁿ.

Answer:

Step-by-step explanation:

False inequality, so no solutions.

\(40 = k(10) \div {4}^{2} \)

\( \frac{40}{10} = \frac{k(10) \div {4}^{2} }{10} \)

\(4 = k \div {4}^{2} \)

\(4 \times {4}^{2} = k \div {4}^{2} \times {4}^{2} \)

\(64 = k\)

//

\(216 = k {(3)}^{2}(12)\)

\( \frac{216}{ {(3)}^{2}(12) } = \frac{k {(3)}^{2}(12) }{ {(3)}^{2}(12)} \)

\(2 = k\)

//

\(72 = k {(2}^{2}) {(3}^{2})\)

\( \frac{72}{ {(2}^{2}) {(3}^{2}) } = \frac{k {(2}^{2}) {(3}^{2} ) }{ {(2}^{2}) {(3}^{2}) } \)

\(2 = k\)

//

\(90 = k(15)(2)\)

\( \frac{90}{(15)(2)} = \frac{k(15)(2)}{(15)(2)} \)

\(3 = k\)

//

\(10 = k(2)\)

\( \frac{10}{(2)} = \frac{k(2)}{(2)} \)

\(5 = k\)

//

Okay, it's pretty much the same process. That's all I can do. good luck!

The correct option regarding the skewness of the distribution is given by:

This is a skewed-left distribution, because the mean is less than the median.

If the mean is greater than the median, the distribution is right-skewed, also called positively skewed. Otherwise, if the median is greater than the mean, the distribution is left-skewed, also called negatively skewed.

In this problem, we have that:

Answer:

x = 3.

Step-by-step explanation:

log4 (3x - 1) = log4 (x + 5)  Since they are both logs to the base 4:

3x - 1 = x + 5

2x = 6

x = 3.

On solving the logarithmic equation, we find that x = 3.

A logarithmic equation is an equation that involves the logarithm of an expression containing a variable.

\(log_{4}(3x-1) = log_{4}(x+5)\\\\3x-1 = x+5\\\\3x-x=5+1\\\\ 2x=6\\\\x=3\)

A variable without a clear operational definition can greatly impact the accuracy and reliability of statistics performed on it. To ensure accurate and meaningful results, it is important to have clear, well-defined variables in any research study.

The lack of a clear definition can lead to inconsistencies in data collection, making it difficult to accurately interpret and analyze the results.

Step 1: When a variable has no clear operational definition, researchers may measure or interpret it in different ways, leading to inconsistencies in data collection.

Step 2: These inconsistencies can affect the reliability and validity of the collected data, which in turn impacts the accuracy of the statistical analysis performed.

Step 3: As a result, the findings from such analyses may not accurately represent the true relationships or patterns within the sample or the population, leading to incorrect conclusions.

The probability of the sample mean being less than 76.5 tons is only 0.00588, which is a very small probability. Therefore, it is more likely that the loader has slipped out of adjustment.

The given data indicates that the mean weight of coal loaded in each car is 77 tons and the standard deviation is 0.9 ton. We have to find the probability that one car chosen at random will have less than 76.5 tons of coal.Using the z-score formula, we have:z = (x - μ)/σz = (76.5 - 77) / 0.9 = -0.5556Now, using the z-score table, we find that the probability of a z-score being less than -0.5556 is 0.2912.Therefore, the probability that one car chosen at random will have less than 76.5 tons of coal is approximately 0.2912.b) As per the central limit theorem, the sample mean is normally distributed, so we can use the standard normal distribution formula to find the probability that 47 cars chosen at random will have a mean load weight x of less than 76.5 tons of coal.

The formula is:z = (x - μ) / (σ / √n)where, x = 76.5 tons, μ = 77 tons, σ = 0.9 tons, n = 47 carsNow, putting the values in the formula, we get:z = (76.5 - 77) / (0.9 / √47)z = -2.511Now, using the z-score table, we get:P(z < -2.511) = 0.00588Therefore, the probability that 47 cars chosen at random will have a mean load weight x of less than 76.5 tons of coal is approximately 0.00588.c) If the weight of coal in one car was less than 76.5 tons, it would not be reasonable to suspect that the loader had slipped out of adjustment, as the standard deviation is 0.9 ton, which means there will always be some variability in the weights of coal loaded into each car, even if the loader is properly adjusted.If the weight of coal in 47 cars selected at random had an average x of less than 76.5 tons, it would be reasonable to suspect that the loader had slipped out of adjustment because the probability of such deviation occurring randomly is very small. This is because the probability of the sample mean being less than 76.5 tons is only 0.00588, which is a very small probability. Therefore, it is more likely that the loader has slipped out of adjustment.

When you do this you see that x corresponds to c on the first triangle.

The 3 angles in a triangle = 180.

Find c by subtracting A and B from 180

C = 180- 29-63 = 88
