Answer:

(x² + 4x + 2)(2x² + 3x - 4) equals 2x⁴ + 11x³ + 12x² - 10x - 8

Step-by-step explanation:

(x² + 4x + 2)(2x² + 3x - 4)

Multiply each term in the first parentheses into the expression in the second parentheses.

2x⁴ + 3x³ - 4x² + 8x³ + 12x² - 16x + 4x² + 6x - 8

Combine like terms.

2x⁴ + 11x³ + 12x² - 10x - 8

So, your answer would be letter choice B.

Answer: B

Step-by-step explanation:

(x^2+4x+2) (2x^2+3x-4)

= x^2 (2x^2+3x-4) + 4x (2x^2+3x-4) +

2 (2x^2+3x-4)

= 2x^4 + 3x3 - 4x^2 + 8x^3 + 12x^2 - 16x + 4x^2 + 6x - 8

= 2x^4 + 11x^3 + 12x^2 - 10x - 8

Suppose each of 12 players rolls a pair of dice 3 times. Find the probability that at least 4 of the players will roll doubles a

polet [3.4K]

Answer:

Our answer is 0.8172

Step-by-step explanation:

P(doubles on a single roll of pair of dice) =(6/36) =1/6

therefore P(in 3 rolls of pair of dice at least one doubles)=1-P(none of roll shows a double)

=1-(1-1/6)3 =91/216

for 12 players this follows binomial distribution with parameter n=12 and p=91/216

probability that at least 4 of the players will get “doubles” at least once =P(X>=4)

=1-(P(X<=3)

=1-((₁₂ C0)×(91/216)⁰(125/216)¹²+(₁₂ C1)×(91/216)¹(125/216)¹¹+(₁₂ C2)×(91/216)²(125/216)¹⁰+(₁₂ C3)×(91/216)³(125/216)⁹)

=1-0.1828

=0.8172

Determine the graph of the sinusoid with amplitude of 4 and period of 2π/3

DiKsa [7]

Answer:

Option b.

y = 4 sin (3x)

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.

Please see the attached image below, to find more information about the graph

The period is

T = 2π/3

This means the frequency in radians is

W = 2π/T = 3

The equation is either:

y = 4 cos(3x)

y = 4 sin (3x)

The correct answer is

Option b.

y = 4 sin (3x)
