Answer:
40,000
Step-by-step explanation:
refer to attached.
the number 4 is found in the Ten Thousands (10,000) place
hence the number 4 has the value of
4 x 10,000
= 40,000
P(TTTTT)=P(T)^5 and P(T)=1/2 so
P(TTTTT)=(1/2)^5
P(TTTTT)=1/32
Answer:
900
Step-by-step explanation:
Margin of error = critical value × standard error
The margin of error is given to be 0.05.
At 99.5% confidence, the critical value is z = 3.
The standard error for a proportion is √(pq/n). Since p is not given, we will assume p = 0.5.
0.05 = 3 √(0.5 × 0.5 / n)
n = 900
Answer:
65
Step-by-step explanation:
78-13=65 or c
Answer:
5, 15, 45 and 135
Step-by-step explanation:
Given the recursive function;
an = 3a(n-1)
If a1 = 5
a2 = 3a1
a2 = 3(5)
a2 = 15
For a3;
a3 = 3a2
a3 = 3(15)
a3 = 45
For a4;
a4 = 3a3
a4 = 3(45)
a4 = 135
Hence the first four terms are 5, 15, 45 and 135
