Answer:

3 : 2

Step-by-step explanation:

We are asked to calculate as a ratio 9 nickels to 3 dimes reduced to lowest terms.  

One nickel means $0.05 and one dime means $0.10.

So, 9 nickels is equal to $(0.05 × 9) = $0.45

And 3 dimes is equal to $(0.10 × 3) = $0.30

Therefore, the ratio will become 0.45 : 0.30 ≡ 3 : 2 (Answer)

The test scores of 40 students are listed below. Find P85.
SIZIF [17.4K]

Answer:

Option A (89).

Step-by-step explanation:

Percentile is a statistic in which the an element at a certain percentage position is determined. To calculate the percentiles accurately, it is important that the data is present in the ascending order. Percentile is an important concept in data analysis. Interestingly, 50th percentile is the median of the data. The difference between the 75th and the 25th percentile is the interquartile range. To find the 85th percentile of the data, calculate 85% of 40, which is the number of elements in the data set. 40 * 85/100 = 34. The number on the 34th position is the 85th percentile of the data. It can be observed that 89 is on the 34th position. Therefore, Option A is the answer!!!
