Answer:
Option C, 1/35
Step-by-step explanation:
Given
Proportion of town that has blue eyes = 1/5 = 0.2
Proportion of town that has brown eyes = 1/7
The probability of choosing either a blue eye or a brown eye person is
Probability of blue eye individual * Probability of brown eye individual
= 1/5 * 1/7 = 1/35
Hence, option C is correct
Y=2w-6 that's the best answer I think
<u>Answer:</u>
Two co planar lines that are perpendicular to the same line are always PARALLEL. So option A is correct.
<u>Explanation:</u>
Given:
- They are perpendicular to the same line
To find:
whether they are parallel or not and choose the correct option from the given options.
Solution:
Now, we know that, slopes of perpendicular lines is -1
Then,
similarly
Now, as both lines are perpendicular to same line, then, we have to equate above both of them.
Then, 
1st line slope = 2nd line slope
Here, slopes of two lines are equal.
Hence, Two coplanar lines that are perpendicular to the same line are always parallel. So option A is correct.
Answer: A simple random sample
Step-by-step explanation:
Simple random sampling refers to the probability sampling whereby the researcher chooses selects a subset of participants from the population.
In this case, every member has an equal chance of being chosen. Since anyone could mail in a response or use the paper's Web site to respond, then it's a simple random sampling.
Solve for 4x + 8y = 32
x = 8 - 2y
Substitute x= 8 - 2y into 5x + 10y = 40
40 = 40
Since 40 = 40 is redundant information, this is dependent system
