Take 87-63 = 24, which is the difference of the 2 hours. Divide this by two to get the hourly rate, which is $12.
We can now set up the equation as follows:
4(12) + x = 63
6(12) + x = 87
Now solve for each:
4(12) + x =63
48 + x = 63
x = $15
6(12) + x = $87
72 + x = 87
x = $15
Therefore, the Flat Fee = $15 and the Hourly rate = $12
Answer: just do 9 times 5.63
Step-by-step explanation:
Answer: D) 0.438 < p < 0.505
Step-by-step explanation:
We know that the confidence interval for population proportion is given by :-
, where n= sample size
= Sample proportion.
z* = critical value.
Given : A survey of 865 voters in one state reveals that 408 favor approval of an issue before the legislature.
i.e. n= 865
Two-tailed critical avlue for 95% confidence interval : z* = 1.96
Then, the 95 % confidence interval for the true proportion of all voters in the state who favor approval will be :-
Thus, the required 95% confidence interval : (0.438, 0.505)
Hence, the correct answer is D) 0.438 < p < 0.505
