Answer: 296

Step-by-step explanation: explicit rule formula for an arithmetic sequence:

a_n = a_1 +(n-1)(d)

20-14= 6

d= 6

a_1 = 8

a_n = 8 + (n-1)(6)

= 8+6n-6

a_n= 6n+2

substitute to find answer:

a_49= 6(49) +2

= 294+2

=296

Which is the equation for AD?<br> -6x+y=6<br> x+y=6<br> -x+y=6<br> 6x+6y=6

romanna [79]

So we have the points (-5,1) for A and (0,6) for D. By using y=mx+b we can determine that y=x+6 which also can be rewritten as -x+y=6.

What can you conclude from a box plot where the length of the left box and whisker is the same as the length of the right box an

Norma-Jean [14]

Answer/Step-by-step explanation:

The length of the boxes and whiskers of a box plot tells us more about the spread the data being represented is and as well as the shape of the spread.

Invariably, if the length of the left box and left whiskers is of the same length as the right box and right whiskers, this implies that the distribution of the data point is close to being symmetric, or approximately symmetrical.
