A) In which day did the learners do the fewest questions? B) Determine the total number of questions worked out in the week. C) Determine the mean number of questions. Solve the inequality: 3(1+x) < 5

Here are the solutions to the problems: 1. Bar Graph Analysis a) In which day did the learners do the fewest questions? Step 1: Read the number of sums done for each day from the bar graph. • Monday: 20 sums • Tuesday: 18 sums • Wednesday: 20 sums • Thursday: 28 sums • Friday: 24 sums Step 2: Identify the day with the minimum number of sums. The minimum is 18, which occurred on Tuesday. The learners did the fewest questions on Tuesday. b) Determine the total number of questions worked out in the week. Step 1: Sum the number of questions from each day. Total = 20 + 18 + 20 + 28 + 24 Step 2: Calculate the sum. Total = 110 The total number of questions worked out in the week is 110. c) Determine the mean number of questions. Step 1: Use the total number of questions from part (b) and the number of days (5). Mean = Total number of questionsNumber of days Step 2: Substitute the values and calculate the mean. Mean = (110)/(5) Mean = 22 The mean number of questions is 22. 2. Solve the inequality 3(1+x) < 5x - 13 Step 1: Distribute the 3 on the left side of the inequality. 3 + 3x < 5x - 13 Step 2: Subtract 3x from both sides of the inequality. 3 < 5x - 3x - 13 3 < 2x - 13 Step 3: Add 13 to both sides of the inequality. 3 + 13 < 2x 16 < 2x Step 4: Divide both sides by 2. (16)/(2) < x 8 < x The solution to the inequality is x > 8. 3. Probability Kombo has six numbers: 4, 7, 9, 11, 21, 23. Find the probability that the number picked is a prime number. Step 1: Identify the total number of possible outcomes. There are 6 numbers in the set. Step 2: Identify the prime numbers in the given set. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. • 4 is not prime (4 = 2 × 2) • 7 is prime • 9 is not prime (9 = 3 × 3) • 11 is prime • 21 is not prime (21 = 3 × 7) • 23 is prime The prime numbers in the set are 7, 11, and 23. There are 3 prime numbers. Step 3: Calculate the probability. P(prime number) = Number of prime numbersTotal number of numbers P(prime number) = (3)/(6) P(prime number) = (1)/(2) The probability that the number picked is a prime number is (1)/(2). 4. Simplify 6a - 2b + 7a - 4b + 2 Step 1: Group the like terms together. (6a + 7a) + (-2b - 4b) + 2 Step 2: Combine the like terms. (6+7)a + (-2-4)b + 2 13a - 6b + 2 The simplified expression is 13a - 6b + 2. Send me the next one 📸
