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:
(c+2) > 6
Step-by-step explanation:
exceeds means greater than...
Y = |x - 3|You need an equation so that you need to add 3 to get the same value. Changing from 'x' to 'x - 3' requires a value (of the second expression) that is 3 larger than the entry in the first expression.
Answer:
Step-by-step explanation:
First, subtract 58% from 100% to get 42%. That means $210 is 42% of this man's income.
Then, convert 42% into a fraction. This would be 21/50. Find the reciprocal of that, which is 50/21.
Now, multiply 50/21 by 210 to get the answer.
(50 * 210)/21
Multiply 50 by 210 to get 10500.
10500/21
(105/21) * 100 is the same as 10500/21.
Divide 105 by 21 to get 5.
5 * 100
Multiply 5 by 100 to get 500.
The man has a $500 income.
Answer:
ABCD ≅ A'B'C'D'
Step-by-step explanation:
When a figure is rotated, its orientation stays the same. This means that the pre-image and the image are labeled in the same direction. Therefore, ABCD ≅ A'B'C'D'
