A dice has 6 sides. All sides have an equal chance of being rolled. The probability of rolling any number on the dice is 1/6. So you take 96 and find 1/6 of it and you do 96 divides by 6. Your answer is 16. Therefore, Adam is expected to roll a 4, 16 times.

Nastasia [14]

Answer:

Step-by-step explanation:

· To provide some context, for an employee who earns $4,000 in each bi-weekly pay period in September through December, approximately $2,200 of Social Security taxes would be deferred.

Convert the polar equation to rectangular form and identify the graph. Support your answer by sketching the graph. Show and expl
Nadusha1986 [10]

The polar equation r = - 4 · cos θ is equivalent to the equation of the circle (x + 2)² + y² = 2², whose radius is 2 and center is (h, k) = (- 2, 0).

<h3>How to transform a polar expression into its rectangular form</h3>

Polar and rectangular forms are related by this relation: (x, y) → (r · cos θ, r · sin θ), where r is the radial distance with respect to the origin and θ is the angle in standard position. We can use this fact to change the given expression into its rectangular form:

r = - 4 · (x / r)

r² = - 4 · x

x² + y² = - 4 · x

y² = - (x² + 4 · x)

y² - 4 = - (x² + 4 · x + 4)

y² - 4 = - (x + 2)²

(x + 2)² + y² = 4

(x + 2)² + y² = 2²

In a nutshell, the polar equation r = - 4 · cos θ is equivalent to the equation of the circle (x + 2)² + y² = 2², whose radius is 2 and center is (h, k) = (- 2, 0).
