The function that represents surviving people are X = 2m - d
Given that there are m married couples and d of the 2m of these couples have died, the total people that remain is expressed as:
Total people remaining = Total married couple - those that died
Total married couple = 2m
Total people that died = d
Taking the difference to get the remaining people;
Total people remaining = 2m - d
Hence the function that represents surviving people are X = 2m - d

Answer:
D Multiply equation B by 5 and equation A by 4 and add the results together
Answer:
(5x + 6) (x + 7)
Step By Step Explanation:
Use the sum form to the product.
5
1. D - Since it's random, everyone has an equal chance of being picked
2. B - Since the people are already registered voters it would be easier to get a response from them. Plus, picking ever 10th person makes it random.
3. false - a fair question wouldn't make assumptions about the population
4. B - "Don't you think" causes the answerer to be pushed towards saying yes

Answer:
(x1 + x4)/2 = 4
Step-by-step explanation:
(x1 + x2+ x3 + x4)/4 = 5 mean
x1 , x2 , x3 , x4
median (x2+x3)/2 = 6
(x2+x3) = 12
The smallest integer is x1, the largest integer x2.
The mean of the largest and smallest of the integers is (x1 + x2)/2.
(x1 + x2+ x3 + x4)/4 = 5
x1 + x2+ x3 + x4 = 20
x1 + 12 + x4 = 20
x1 + x4 = 20 - 12
x1 + x4 = 8
(x1 + x4)/2 = 8/2
(x1 + x4)/2 = 4
