Answer:

Reject the null hypothesis.

Step-by-step explanation:

n1 = 16

n2 = 21

S.V1 = 5.8

S.V2 = 2.4

\alpha = 0.05

H_{0} = Population Variance 1 ≤  Population Variance 2

H_{a} = Population Variance 1 >  Population Variance 2

Test statistic value = 5.8 / 2.4 = 2.417

Degrees of freedom is n - 1

15 and 20

Critical value is F_{0.05} = 2.2

2.417 > 2.2

we reject the null hypothesis as the critical value is greater than the test statistic.

Two types of barrel units were in use in the 1920s in the united states. the apple barrel had a legally set volume of 7056 cubic
r-ruslan [8.4K]
1.) 7,056 * 41 = 289,296 (apple barrel volume * no. of barrels sold)
     5,826 * 41 = 238,866 (cranberry barrel volume * no. of barrels sold)

2.) Subtract cranberry barrel volume from apple barrel volume
    289,296 - 238,866 = 50,430 cubic inches

3.) Convert 50,430 cubic inches to liters
     50,430 = 826.39 liters or 826.40 liters (rounded off)

4.) Therefore, 826.40 liters is the discrepancy in the shipment volume.

myrzilka [38]

Answer:

19 days

Step-by-step explanation:

1 - Make an equation with the variables provided.

150 + 200 + 12.50x = 587.50

2 - Simplify both sides.

350 + 12.50x = 587.50

3 - Subtract 350 from both sides.

12.50x = 237.50

4 - Divide by 12.50 to find your x variable.

x = 19 days

Brainliest would be appreaciated! :-)

Explain what terms and degrees are and how. How are they used to classify polynomials? Also explain why this polynomial (4x2y +
user100 [1]
When a polynomial has more than one variable, we need to look at each term. Terms are separated by + or - signs. Find the degree of each term by adding the exponents of each variable in it. <span>The degree of the polynomial is found by looking at the term with the highest exponent on its variables.
</span>
Polynomials can be classified in two different ways - by the number of terms and by their degree. A monomial is an expression with a single term. It is a real number, a variable, or the product of real numbers and variables. A polynomial is a monomial or the sum or difference of monomials. A polynomial can be arranged in ascending order, in which the degree of each term is at least as large as the degree of the preceding term, or in descending order, in which the degree of each term is no larger than the degree of the preceding term. 

The polynomial (4x^2y + 5xy) is classified as a 3rd degree binomial, because the monomial 4x^2y has degree equal to 3 and the monomial 5xy has degree equal to 2. The highest degree is 3, therefore the polynomial (4x^2y + 5xy) is classified as a 3rd degree polynomial. Since polynomial <span><span> (4x^2y + 5xy)</span> has two terms, then it is classified as binomial.</span>
