Answer:

1998

Step-by-step explanation:

Final answer:

The phrase '9 more than the product of 51 and a number t' translates to the mathematical expression 51t + 9.

Explanation:

The question is asking for an expression representing '9 more than the product of 51 and a number t'. In mathematical terms, this can be expressed as: 51t + 9 .The key step here is understanding that 'the product of 51 and a number t' refers to multiplication: 51 multiplied by t (which can be written as 51t). Then, '9 more than' this product means simply adding 9 to that solution. So, the entire translating phrase becomes 51t + 9, which is the equivalent mathematical expression.

Answer: The percentile that corresponds to an age of 36 years old in the given data set is approximately 22.22%.

Step-by-step explanation:

To find the percentile that corresponds to an age of 36 years old in a data set representing the ages of 36 executives, we can use the following steps:

Step 1: Arrange the data set in ascending order.

- Let's assume the data set is as follows (in ascending order): 28, 30, 31, 32, 33, 34, 35, 36, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63.

Step 2: Calculate the rank of the given age.

- The rank is the position of the given age within the data set.

- In this case, the given age is 36 years old, and its rank is 8 because it is the 8th value in the data set.

Step 3: Calculate the percentile using the rank and the total number of data points.

- The percentile can be calculated using the following formula:

Percentile = (Rank / Total number of data points) x 100

- In this case, the total number of data points is 36 (since there are 36 executives' ages in the data set).

- Plugging in the values, we get:

Percentile = (8 / 36) x 100

Percentile ≈ 22.22 (rounded to two decimal places)
