Answer:
Step-by-step explanation:
There are 14 triangles. The strategy used is looking at the paper for triangles.
Answer:
24, -38, 62, -100
Step-by-step explanation:
The recursive formula is a_n = a_(n-2) - a_(n-1)
so. we try this 4 times after the -14 term
a_3 = -4 = 2 - 6 = a_1 - a_2
...
a_6 = a_4 - a_5 = 10 - (-14) = 24
a_7 = a_5 - a_6 = -14 - (24) = -38
a_8 = a_6 - a_7 = 24 - (-38) = 62
a_9 = a_7 - a_8 = -38 - 62 = -100
a_10 = a_8 - a_9 = 62 - (-100) = 162
13.9%.
7.2 x 10^9 = 7,200,000,000.
Since 1 billion = 1,000,000,000 out of these 7,200,000,000 do not have access to clean water, we find the percent by taking:
1,000,000,000/7,200,000,000 = 10/72 = 13.9%
Answer: c
Step-by-step explanation:
C is the only that gave us a single outcome so it’s a simple event
