Hello :
the nth term ( general term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d , A1 : the first terme
A1 = 5 and : d = 1 - 5 = - 4 n = 21
A21 = 5 + (21 -1)(-4)
A21 = 5 - 80 = -75

Answer:
7/9
Step-by-step explanation:
P(blue) = 2:7
This means there are 2 blue parts for every 7 nonblue parts. So 9 parts total! 2:7, then, should be thought of as 2/9.
P(not blue) = 1 - 2/9
= 7/9
Think about it: there must be a total probability of 1, so the probability of <em>not</em> getting blue must be 7/9.
Answer:
(-4, -3), (4, -1), (8, 0), (12, 1)
Step-by-step explanation:
The x- and corresponding y-values are listed in the table. Put each pair in parentheses, <em>x-value first</em>. (That is an <em>ordered pair</em>.)
(x, y) = (-4, -3) . . . . from the first table entry
(x, y) = (4, -1) . . . . from the second table entry
(x, y) = (8, 0) . . . . from the third table entry
(x, y) = (12, 1) . . . . from the last table entry
Answer:
9 boxes
Step-by-step explanation:
Since 1 ft= 12 inches then with diameter of 12 ft, radius becomes 6 ft and converted to inches it's 6*12=72 in
Area of 1 tile= 9*9=81
Number of tiles= 
Number of boxes= 202/25=8.08 boxes hence 9 boxes
