User: Perform the modular arithmetic operation. -12 (mod 5) A. 1 B. 2 C. 0 D. 3 Weegy: 2w - 2 = -12, 2w=-10, w=-5 User: Use the simple interest formula to find the missing value. Rates are annual rates. Assume 360 days per year and 30 days per month. p = ?, r = 4.5%, t = 10 days, i = $26.68 A. p = $21,344.00 B. p = $711.47 C. p = $7114.67 D. p = $21,670.09 Weegy: The answer is A. p = $21,344.0 The formula is 26.68 * 36) / 0.045 = 21 344 User: Write as a decimal. 249.4% A. 24.94 B. 24,940 C. 249.4 D. 2.494 Weegy: 249.4% = D.2.494 User: Solve the problem.

Three noncollinear points determine a triangle. How many triangles can be formed with 8 points, no three of which are collinear? A. 56 B. 24 C. 336 D. 6720
Weegy: I take it that's "no three of which are collinear." I also assume that "can be formed" ought to have been 'are determined by," because any triangle is actually composed of infinite points. This is equivalent to asking how many different [ combinations of 3 points we can select from the 8 possibilities, because each combination determines a different triangle. C(8,3) = 8! / (5! 3!) = 8*7*6 / (3*2*1) = 56 triangles. ] User: If 5 apples in a barrel of 25 apples are rotten, what is the expected number of rotten apples in a sample of 2 apples? A. 0.4 B. 1 C. 0.63 D. 0.33 Weegy: The answer is: Given the initial condition, the probability of an apple being rotten is 5/25 or 1/5, so 1/5*2=2/5, but of course you can not have 2/5 of a rotten apple, so you should round up to 1 apple. User: Find the probability. A die is rolled 20 times and the number of twos that come up is tallied. Find the probability of getting exactly five twos. A. 0.129 B. 0.921 C. 0.003 D. 0.083 Weegy: The answer is A. 0.129. The formula is: P(Five 2s) = (20C5) [(1/6)^5] [(5/6)^15] = 15504*0.000128601*0.064905472 = 0.129410292 User: How many ways can the letters in the word "WISCONSIN" be arranged? A. 38,572 B. 45,360 C. 69,620 D. 362,880 Weegy: The answer is B. 45,360 The formula is 9 letters i repeats twice n repeats twice s repeats twice User: A die is rolled 20 times and the number of twos that come up is tallied. Find the probability of getting exactly four twos. A. 0.202 B. 0.075 C. 0.101 D. 0.083 Weegy: 0.202 is the final answer. It's A. User: How would you find the empirical probability of getting a red card, if you are choosing a card from an ordinary deck of 52 cards? A. Choose a card from a deck of 52 cards many times and then find the relative frequency of red cards.

Two marbles are drawn without replacement from a box with 3 white, 2 green, 2 red, and 1 blue marble. Find the probability. The second marble is white given the first marble is blue.
Weegy: First marble is white: 3/(1+3+2+2)=3/8 For the second to be blue: 1/(1+3+2+2-1)=1/7 User: How would you find the empirical probability of getting a red card, if you are choosing a card from an ordinary deck of 52 cards? A. Choose a card from a deck of 52 cards many times and then find the relative frequency of red cards. This would be done by dividing the number of times a red card has occurred by the total number of times a card was chosen. B. Choose a card from a deck of 52 cards 2 times and then find the relative frequency of red cards. This would be done by dividing the number of times a red card has occurred by 2. C. The empirical probability cannot be determined. D. Choose a card from a deck of 52 cards 52 times and then find the relative frequency of red cards. This would be done by dividing the number of times a red card has occurred by 52. Weegy: D. Choose a card from a deck of 52 cards 52 times and then find the relative frequency of red cards. This would be done by dividing the number of times a red card has occurred by 52.
