Question

Alden is registering for classes next semester. He uses the Quantitative Reasoning Process to decide between two teachers, Dr. Alvarez, and Dr. Bareno . He speaks to 18 friends that previously took the course from Dr. Alvarez and also speaks to 16 friends that took it from Dr. Bareno. Eight of his friends said they highly recommend Dr. Alvarez. Eleven of his friends highly recommend Dr. Bareno.

Based on Alden's minimal study, what percent of students "highly recommend" Dr. Alvarez?

Answer 1

To find the percentage of students who highly recommend Dr. Alvarez, you divide 8 (the number of friends who recommended him) by 18 (total friends who took his class) and then multiply by 100, resulting in approximately 44.44%.

Step-by-step explanation:

To calculate the percentage of students who highly recommend Dr. Alvarez, we divide the number of friends who recommended him by the total number of friends who took the class with him and then multiply the result by 100 to get the percentage.

Step-by-Step Calculation:

Number of friends recommending Dr. Alvarez: 8
Total number of friends who took Dr. Alvarez's class: 18

Percentage recommending Dr. Alvarez = (Number of friends recommending Dr. Alvarez / Total number of friends who took Dr. Alvarez's class) × 100

Percentage recommending Dr. Alvarez = (8 / 18) × 100

Percentage recommending Dr. Alvarez = 0.4444... × 100

Percentage recommending Dr. Alvarez = 44.44% (approximately)

Therefore, about 44.44% of students highly recommend Dr. Alvarez based on Alden's minimal study.
