Answer:

B. Division

Step-by-step explanation:

Subtraction is closed for polynomials subtracting two polynomials will result in another polynomial. Same goes with multiplication. However, if you divide polynomials, you are able to get a result that is not always a polynomial. Therefore, division is the answer.

A right rectangular prism has a volume of 470.40 cm³. The length of the solid is 6.4 cm and the width is 9.8 cm.

Bogdan [553]

V = l * w * h
470.40 = 6.4 * 9.8 * h
Multiply the length and width on the right side of the equation.

470.40 = 62.72 * h
Divide both sides by 62.72
7.5 cm = h

CHECK
V = l * w * h
V = 6.4 * 9.8 * 7.5
V = 470.4 cm^3

The answer is 5*x^4 evaluates to Multiply the exponent of x by 4giving The answer is x^4 evaluates to Multiply and 6 Multiply and 1 The just gets copied along. The answer is 6*x^4 evaluates to Multiply the exponent of x by 2giving The answer is x^2 evaluates to Multiply and 3 Multiply and 1 The just gets copied along. The answer is 3*x^2 evaluates to 6*x^4-3*x^2 evaluates to The answer is 6*x^4-3*x^2+7 evaluates to Multiply by we multiply by each term in term by term. This is the distributive property of multiplication. Multiply and Multiply the and Multiply and Combine the and by adding the exponents, and keeping the x, to get The answer is × = Multiply and Multiply the and Multiply and Combine the and by adding the exponents, and keeping the x, to get The answer is × = Multiply and 7 Multiply and 1 The just gets copied along.

3. Suppose the mystery bag had resulted in the following number of red chips. Using the simulated sampling distributions found e

Vinvika [58]

Answer:

a) 0.172

b) 0.167

c) 0.1404

Step-by-step explanation:

Margin of error, E = $2\times\sqrt{\frac{p(1-p)}{n}}$

here,

p = probability of the event

n = sample size

a) n = 30

p = 10 ÷ 30 = 0.333

Therefore,

E = $2\times\sqrt{\frac{0.333(1-0.333)}{30}}$

= 2 × 0.0861

= 0.172

b) n = 30

p = 21 ÷ 30 = 0.7

Therefore,

E = $2\times\sqrt{\frac{0.7(1-0.7)}{30}}$

= 2 × 0.0836

= 0.167

c) n = 30

p = 22 ÷ 50 = 0.44

Therefore,

E = $2\times\sqrt{\frac{0.44(1-0.44)}{50}}$

= 2 × 0.0702

= 0.1404
