damaskus [11]

Answer:

- \frac{1}{2}

Step-by-step explanation:

Given

\frac{x^2y^8}{x^7y^6}

= \frac{y^{(8-6)} }{x^{(7-2)} }

= \frac{y^2}{x^5} , substitute values

= \frac{4^2}{(-2)^{5} }

= \frac{16}{-32}

= - \frac{1}{2}

A single die is rolled twice. Find the probability of rolling an oddnumber the first time and a number greater than 2 the second
harkovskaia [24]

Answer:

1/3.

Step-by-step explanation:

The 2 events are independent so we multiply the 2 probabilities.

Prob(rolling an odd number) = 3/6 = 1/2.

Prob(rolling a number greater than 2) = 4/6 = 2/3.

The required probability = 1/2 * 2/3

= 2/6

= 1/3.

PLEASE HELP!!!!<br><br> f(x)= {____for____<br> {____for____
hammer [34]

9514 1404 393

Answer:

  f(x)=\left\{\begin{array}{ccc}3&\text{for}&-5\le x < 0\\1-x&\text{for}&0

Step-by-step explanation:

The left section is defined at x = -5, but not at x = 0, so the interval for that definition is -5 ≤ x < 0. The function value on that interval is constant: 3.

The right section is defined a x = 5, but not at x = 0, so the interval for that definition is 0 < x ≤ 5. That section is a straight line with a slope of -1 and a y-intercept of 1. The function value on that interval can be written -x+1.

Then the piecewise definition is ...

  f(x) = {3, for -5 ≤ x < 0; -x+1, for 0 < x ≤ 5}
