An expression is shown below. (x^3/4)(x^2/3)

1 answer:

3 0

For all exponents, (a^n a^m) = a^(n+m)
apply same rules (X^3X^2)/(4*3)
Combine powers. (X^3X^2)/4*3 = X^(3+2)/4*3
X^5/12

Suppose customers in a certain queue are served one at a time sequentially, that the time for each individual customer is Expone

alexandr402 [8]

Answer:

The shape and rate parameters are $\frac{1}{12}$ and $3$ .

Step-by-step explanation:

Let X = service time for each individual.

The average service time is, β = 12 minutes.

The random variable follows an Exponential distribution with parameter, $\lambda=\frac{1}{\beta}=\frac{1}{12}$ .

The service time for the next 3 customers is,

Z = X₁ + X₂ + X₃

All the X $_{i}$ 's are independent Exponential random variable.

The sum of independent Exponential random variables is known as a Gamma or Erlang random variable.

The random variable Z follows a Gamma distribution with parameters (α, n).

The parameters are:

$\alpha =\lambda=\frac{1}{12}\\n=3$

Thus, the shape and rate parameters are $\frac{1}{12}$ and $3$ .

Answer:

d. 15 square yard

Step-by-step explanation:

$area \: of \: shape \\ = \frac{1}{2} \times base \times height \\ \\ = \frac{1}{2} \times 10 \times 3 \\ \\ = \frac{1}{2} \times 30 \\ \\ = 15 \: {yd}^{2}$

Choose one of the factors of x^3 + 343.

Debora [2.8K]

First, note that $343=7^3.$ Then use the formula for the sum of perfect cubes:

$a^3+b^3=(a+b)(a^2-ab+b^2).$

Therefore,

$x^3 + 343=x^3+7^3=(x+7)(x^2-7x+49).$

The quadratic trinomial $x^2-7x+49$ couldn't be factored anymore, so the expression $x^3 + 343$ has two factors $x+7$ and $x^2-7x+49.$

Answer: correct choice is A.
