Answer:
B, an = 4n - 9
Step-by-step explanation:
The sequence is for every time the exponent on a goes up one, the number that it equals to goes up by 4. So to find the nth term, we at 4 to n. I hope this helped! :)
0.1 0.2 because its only sum of only 0.3
To Solve MAD or the mean absolute deviation what you need to do is get the Mean so lets say you have the numbers 20,35,18,34,60,82,10, and 29 add them up to get 228. next divide by the amount of numbers 228/8 = 36 now to get the mean absolute deviation get the difference of each number, but some will be negative so we will turn them to positive Like so.
20-36=-16 turn to positive 16
36-35=1
36-18=18
36-34=2
60-34=24
82-34=46
36-10=26
and 36-29=7
you add up these numbers to get 140 then divide them by the numbers 140/8=17.5
<span>so 17.5 is your mean absolute deviation.</span>
Answer:
y = 7x + 4? - 7 7
Step-by-step explanation:
90% off means is is selling for 10% of the original price.
Multiply original price by 10%
107 x 0.01 = $10.70
It is selling for $10.70
