Answer:
305
Step-by-step explanation:
We are adding 3 each time
5+3 = 8
8+3 = 11
The formula for an arithmetic sequence is
an = a1+d(n-1) where a1 is the first term and d is the common difference
an = 5+3(n-1)
We want the 101 term
a101 = 5 +3(101-1)
= 5+3(100)
= 5+300
= 305
Answer:
Mean = sum of all elements/number of elements
= (7.5 + 10.5 + 5 + 4.5 + 3.5 + 7.5 + 4 + 10 + 7.5 + 5)/10
= 6.5
=> Option C is correct
Hope this helps!

Answer:
Step-by-step explanation:
Givens
Lake Eyre (Austrialia) = 15 meters below sea level = - 15
Pensacola (Florida) = + 12 metes above sea level
Solution
Distance between = Pensacola - Lake Eyre
Distance between = 12 - - 15
Distance between = 27
Answer
27 meters.
Answer:
x = -18/83
Step-by-step explanation:
8(9x+3)=3(2-5x)+4x
72x + 24 = 6 - 15x + 4x
72x + 15x - 4x = 6 - 24
83x = -18
x = -18/83
