Answer:
There is enough evidence to support the claim that the percentage of residents who favor annexation is more than 47%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1000
p = 47% = 0.47
Alpha, α = 0.05
First, we design the null and the alternate hypothesis
This is a one-tailed(right) test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.0056
Since the p-value is lower than the significance level, we fail to accept the null hypothesis and accept the alternate hypothesis.
Thus. the percentage of residents who favor annexation is more than 47%.
Thus, there is enough evidence to support the claim that the percentage of residents who favor annexation is more than 47%.

Step-by-step explanation:
The height is 5 cm
Explanation:
The formula for volume is v = lwh. (L is length, w is width, and h is height." Since we know the volume, the length, and the width, we can substitute those numbers in.
240 = (12)(4)h
Now we will solve this equation
1) Simplify the right side : multiply 4 x 12
240 = 48h
2) Since we want one h instead of 48, we divide 48 by both sides of the equation
240/48 = 48h/48
5 = h
Therefore, the height is 5 cm
