Answer:
T is time, so replace t with 2 seconds and solve:
-16(2)^2 + 48(2)
-16(4) + 96
-64 + 96 = 32
The ball is 32 feet high in 2 seconds
Explanation:
The confidence interval and the interpretation of it is; CI = (0.34, 0.40) which means that the 95% confidence interval for the proportion of all people in the United States who would indicate that their favorite sport to watch on television is American football is (0.34, 0.40).
<h3>What is the confidence interval?</h3>
We are given;
Sample proportion; p = 37% = 0.37
Sample size; n = 1000
The confidence interval for the population proportion, is given by the formula;
CI = p ± z√[(p(1 - p)/n)]
z for Confidence level of 95% is z = 1.96.
Thus;
CI = 0.37 ± 1.96√[(0.37(1 - 0.37)/1000)]
CI = 0.37 ± 0.03
CI = (0.34, 0.40)
Thus, the 95% confidence interval for the proportion of all people in the United States who would indicate that their favorite sport to watch on television is American football is (0.34, 0.40).

The description on the graph is: (c) after 30 seconds, she turned it down to low for 30 seconds. She turned it back to high for 60 seconds, then turned it off.
From the complete question, we have the following highlights
- The graph has three horizontal lines
- One of the lines is on the x-axis
- The other lines represent high and low, and they have intervals of 30 and 60 seconds, respectively
Hence, the description on the graph is:
- After 30 seconds, she turned it down to low for 30 seconds.
- She turned it back to high for 60 seconds, then turned it off.
