Part A:
Given that 18% of the population is left handed, in a sample of 6 customers, we expect to see 0.18 x 6 = 1.08 lefties.
Part B:
Given that the proportion of lefties is 18% or 0.18 and the proportion of non-lefties is 100 - 18 = 82% or 0.82.
Since the sample size is 6, the sample standard deviation is given by:
Answer:1.16 is the answer
Step-by-step explanation:

18.8 ft 6.266667 yd
19.8 ft 6.6 yd
20.8 ft 6.933333 yd
21.8 ft 7.266667 yd
22.8 ft 7.6 yd
23.8 ft 7.933333 yd
24.8 ft 8.266667 yd
So this is area and perimeter. you have to add and subtract
Answer:
A
Step-by-step explanation:
We know million has 6 zeros.
So, 1 million would be written as:
1,000,000
Similarly, 27 million would be written as:
27,000,000
We know writing a number in scientific notation would make this a decimal in 1 decimal place, so we would select "2.7" as the base of the scientific number.
Now, how many places to the right do we need to go (in 2.7) to make it 27,000,000?
Counting, we see: 7 places
So, power of 10 would be "7", thus we can write:

Answer choice A is right
Answer:

Step-by-step explanation:
These are the terms of an arithmetic sequence with n th term
= a + (n - 1)d
where a is the first term and d the common difference
d = 25 - 20 = 30 - 25 = 5 and a = 20, hence
= 20 + 5(n - 1) = 20 + 5n - 5 = 5n + 15 ← n th term formula
