Answer:
1) m = negative StartFraction 10 over 4 EndFraction
2) m = negative five-halves
3) m = 
Step-by-step explanation:
<u>The given equation is:</u>
=> 
Subtracting 3/4 to both sides
=> m =
=> m = 
=> m = 
Answer:
n + 1 = 24 million x 1.15
Step-by-step explanation:
The sales is increased 15 percent, so every year 24million is multiplyed with 1.15 to get the result... so yea
Answer:
C. Different sample proportions would result each time, but for either sample size, they would be centered (have their mean) at the true population proportion.
Step-by-step explanation:
From the given information;
A political polling agency wants to take a random sample of registered voters and ask whether or not they will vote for a certain candidate.
A random sample is usually an outcome of any experiment that cannot be predicted before the result.
SO;
One plan is to select 400 voters, another plan is to select 1,600 voters
If the study were conducted repeatedly (selecting different samples of people each time);
Different sample proportions would result each time, but for either sample size, they would be centered (have their mean) at the true population proportion. This is because a sample proportion deals with random experiments that cannot be predicted in advance and they are quite known to be centered about the population proportion.
