This is a geometric sequence with a common ratio of 2
an = a1 * r^(n - 1)
n = term to find = 21
a1 = first term = 0.05
r = common ratio = 2
now we sub
a21 = 0.05 * 2^(21 - 1)
a21 = 0.05 * 2^20
a21 = 0.05 * 1048576
a21 = 52428.80 <==== after working 21 days

Answer:
22% probability the student is a junior.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes:
The table says that:
There are 4 + 6 + 2 + 2 + 3 + 4 + 6 + 6 + 3 = 36 total students.
2 + 6 = 8 are juniors.
If a student is selected at random, find the probability the student is a junior.
8/36 = 0.2222 = 22.22%
Rounding to the nearest whole percent, 22% probability the student is a junior.
Answer:
The correct option is C) 5, 5/2
The sequence given is:
80, 40, 20, 10, _____, ______
If we look at the given numbers, it appears that every next number is obtained by dividing the previous number of 2.
Like 40 is obtained by dividing 80 by 2
Similarly:
Therefore, the complete sequence is:
80, 40, 20, 10, 5, 5/2
Hence the correct option is C) 5, 5/2
Answer:
62 degrees
Step-by-step explanation:
X and 28 degrees are on a 90 degree corner, 28 degrees needs to be subtracted from 90 degrees to get the value of x so, 90 - 28 = 62 degrees
