Answer:
x = 10 and BD = 74
Step-by-step explanation:
AE and CE are equal, so we can set those 2 values equal to each other to find x.
3x + 7 = 37
3x = 30
x = 10
BD will be equal to AE + CE because that is a property of the rectangle.
So AE + CE = 37 + 37 = 74.
BD = 74
The answer is 10 Mark brainiest please
Using the z-distribution, as we have a proportion, the 95% confidence interval is (0.2316, 0.3112).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
- is the sample proportion.
In this problem, we have a 95% confidence level, hence, z is the value of Z that has a p-value of , so the critical value is z = 1.96.
We also consider that 130 out of the 479 season ticket holders spent $1000 or more at the previous two home football games, hence:
Hence the bounds of the interval are found as follows:
The 95% confidence interval is (0.2316, 0.3112).
