The correct option is (a)

As x ⇒ ∞, f(x) ⇒ -∞ and As x ⇒ -∞, f(x) ⇒ ∞.

What is Polynomial function ?

The terms poly and nomial combine to form the word polynomial. We can define polynomials as "algebraic expressions with many terms" because "poly" means many and "nomial" denotes the term.

Given : f(x)= -2x^3 +3x^2 +2x -1

In order to determine the end behavior of the polynomial function, we are required to check the highest degree of the polynomial and the coefficient of the term which has highest degree.

Here, The highest degree of the polynomial is 3 and the coefficient of the term which has highest degree is -2.

Since, the coefficient is negative, the graph will move right down which means as x ⇒ ∞, f(x) ⇒ -∞.

Similarly, the degree is odd which states that the sign will be opposite of what the coefficient has. So,  As x ⇒ -∞, f(x) ⇒ ∞.

Hence, As x ⇒ ∞, f(x) ⇒ -∞ and As x ⇒ -∞, f(x) ⇒ ∞.

The regression line is yˆ = 4 + 1.891x , the coefficient of determination of two variables or the fraction of the variation in y that can be explained by the variation in the values of x is 0.51..

Here the fitted regression equation of y on x is

yˆ = 4 + 1.891x ---(*)

where, x --> Independent variable

yˆ --> predicted value of the dependent variable

Now, b₁ = slope cofficient = 1.891 ~ 1.91

(estimated from least squares method)

We have given that,

Standard deviations for X = 1.34 = sₓ say

Standard deviations for Y = 3.6 = sᵧ say

we know, b₁ = r₀( sₓ/sᵧ ) where ro is corr(X,Y)

=> 1.91 = r₀ (3.6/1.34)

=> 1.91×1.34/ 3.6 = r₀

=> r₀ = 0.71944

Defining, R² = cofficient of determination of two variables = Proportion of variation in Y , explained by the variation in the value of X, through the regression model.

= (r₀)² = (0.71944)² = 0.505442

R² = 0.505442 ~ 0.51 (in two decimals)

The cost per ounce is $0.156

An ounce is a unit of weight and mass in the Imperial and United States customary systems of measurement. It is commonly used to measure the weight of precious metals such as gold, silver, and platinum. In the US, the ounce is equal to 28.35 grams. The ounce is also used to measure the weight of food items, liquids, and other substances. In the UK, the ounce is equal to 28.4 grams. The ounce is also used to measure the weight of postage stamps, coins, and other small items. The ounce can also be used to measure the volume of a liquid. One fluid ounce is equal to 29.57 milliliters. A dry ounce is equal to 28.35 grams. An ounce is also one-sixteenth of a pound.

Solution:

1 pound is equal to 16 ounce

6 pounds of coffee = 6 x 16 = 96 ounce

So take $14.99 and divided it into 96

the cost of per ounce is equal to 14.99 / 96 = 0.156

Using statistics we know that the mean value is 5.6 years, and the standard error is 0.4478.

The gathering, characterization, analysis, and drawing of inferences from quantitative data are all tasks that fall under the purview of statistics, a subfield of applied mathematics.

Probability theory, linear algebra, and differential and integral calculus play major roles in the mathematical theories underlying statistics.

So, we have:

μ = 5.6

σ = 1.9

n =  18

Figuring out each sample's mean:

Therefore, the population means itself serves as the best estimator of the sample mean.

μₓ = μ = 5.6

The sample mean is 5.6 years as a result.

Estimating the standard deviation:

By using the formula:

Standard error = σ/√n

Given that the samples are of size n = 18 and the standard deviation is = 1.9:

Standard error = 1.9/√18 = 0.4478

Therefore, using statistics we know that the mean value is 5.6 years, and the standard error is 0.4478.

The accumulated value of an investment of $4,000 at 5% compounded semiannually for 8 years is $5,938.02.

When you add the interest you have already earned back into your principal balance, you are earning compound interest, which increases your profits.

Compound interest, also known as interest on principal and interest, is the practise of adding interest to the principal amount of a loan or deposit.

Given:

Investment amount= $4000

Rate of Interest, R= 5%

Time= 8 years semiannually

So, r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P[tex](1 + r/n)^{nt[/tex]

A = 4,000.00[tex](1 + 0.05/2)^{(2)(8)[/tex]

A = 4,000.00[tex](1 + 0.025)^{(16)[/tex]
