Send help please, i struggled with these kinds of questions minutes ago!

  5 +4(n -1)

Step-by-step explanation:

The wording "the same number of sticks is added each time" tells you this is an arithmetic sequence. To find the rule, you need to know ...

The form of the rule for the n-th term of an arithmetic sequence is ...

  an = a1 +d(n -1) . . . . . . a1 = first term; d = common difference

For a1 = 5 and d = 4, your rule for the n-th pattern is ...

  sticks in n-th pattern = 5 +4(n -1)

This can be simplified to 1 +4n.

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
