The difference between a frequency histogram and a relative frequency histogram is that the relative frequency histogram indicates:. A) counts on the vertical (y)axis, whereas a frequency histogram indicates percentages.
B) counts on the horizontal (x)axis, whereas a frequency histogram indicates percentages.
C) percentage of observations on the horizontal (x)axis, whereas a frequency histogram indicates counts.
D) percentage of observations on the vertical (y)axis, whereas a frequency histogram indicates counts.

d. percentage of observations on the vertical (y) axis, whereas a frequency histogram indicates counts.

Step-by-step explanation:

A frequency histogram is a graph showing the frequency for the occurrence of an outcome in a data set. A frequency histogram is used to organize data thereby making the data easy to comprehend.

A frequency histogram is a graph that shows how the number of times a particular thing happens, and this is shown in percentages.

Fir an histogram, the horizontal axis is a number line that contains classes of uniform length while the frequency or count is represented on the vertical axis.

The difference between a frequency histogram and a relative frequency histogram is that the relative frequency histogram indicates percentage of observations on the vertical (y) axis, whereas a frequency histogram indicates counts.

Therefore, option d is correct.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
