Problem 5 (4+4+4=12) We roll two fair 6-sided dice. Each one of the 36 possible outcomes is assumed to be equally likely. 1) Fin

d the probability that doubles (i.e., having an equal number on the two dice) were rolled. 2) Given that the roll resulted in a sum of 4 or less, find the conditional probability that doubles were rolled. 3) Given that the two dice land on different numbers, find the conditional probability that at least one die is a 1.

1 2 3 Step-by-step explanation: Generally, during the roll of two fair 6-sided dice, the doubles result in (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6). Therefore, the total for doubles is N = 6. The outcome of rolling two fair 6-sided dice yields n = 36. Thus, the probability of rolling doubles (matching numbers on both dice) is calculated mathematically. When rolling two fair dice, outcomes that sum to 4 or less are (1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (3, 1). Observing this, we see two doubles present. Consequently, the conditional probability of rolling doubles is represented mathematically. Lastly, when rolling the two fair dice, outcomes that show different numbers result in L = 30, while outcomes where at least one die shows a 1 give W = 10. Hence, the conditional probability of having at least one die show a 1 is presented mathematically.

The yearly cost in dollars, y, for a member at a video game arcade based on total game tokens purchased, x, is y =y equals Start
Leona [12618]

Response:

y = \frac{1}{5}x

Step-by-step explanation:

Given data:

Annual cost for members: y = \frac{1}{10}x + 6

Required:

Calculate the yearly expense for non-members

From the context, we infer that:

A non-member pays $0.20 per game;

Annual cost can be determined using the formula;

y = Amount * Number of Games

Where:

Amount = $0.2, Number of Games = x

y = 0.20 * x

Convert 0.2 to a fraction:

y = \frac{2}{10} * x

Divide the numerator and denominator by 2:

y = \frac{1}{5} * x

y = \frac{1}{5}x

Therefore, the yearly expense for non-members is

y = \frac{1}{5}x

I need to know how to factor 16a4-b4
babunello [11817]
This represents a difference of squares:

(16a^4 - b^4)

= (4a^2 + b^2)(4a^2 - b^2)

Furthermore, the second bracket can be simplified as it is also a difference of two squares:

(4a^2 + b^2)(4a^2 - b^2)

= (4a^2 + b^2)(2a - b)(2a + b)
