The number of chips of different colors in Vicky's bag is shown below:

5 blue chips
11 pink chips
9 white chips
Vicky takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Vicky takes out a blue chip in both draws? (5 points)

5 over 25 multiplied by 5 over 25 equals 25 over 625
5 over 25 multiplied by 5 over 25 equals 25 over 625
5 over 25 multiplied by 4 over 24 equals 20 over 600
5 over 25 plus 4 over 24 equals 220 over 600

Alicia rolls two fair number cubes numbered from 1 to 6. She first defines the sample space, as shown below:

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)
(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)
(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)
(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)

Based on the sample space, what is the probability of getting a total of 7? (5 points)

There are 4 cards with a picture of a rose and 3 cards with a picture of a daisy. Fiji keeps all the cards face down on the table with the pictures hidden and mixes them up. She then turns over one card and finds the picture of a rose on it. She removes this card from the table and turns over another card without looking. What is the probability that the card that Fiji turns over has a rose on it? (5 points)

Evaluate 8x2 + 9x βˆ’ 1 2x3 + 3x2 βˆ’ 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 βˆ’ 2x = x(2x2 + 3x βˆ’ 2) = x(2x βˆ’ 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x βˆ’ 1 x(2x βˆ’ 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x βˆ’ 1)(x + 2), obtaining 8x2 + 9x βˆ’ 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x βˆ’ 1).
