The height of an object can be represented as a function of time.
It takes the rocket 25 seconds to hit the ground
The height function is given as:
When the rocket hits the ground, we have:
h(t) = 0
So, the height function becomes
Rewrite as:
Divide both sides by 16t
Hence, it takes the rocket 25 seconds to hit the ground

Answer:
42
Step-by-step explanation:
I would guess that Saul had 42 belts before because 42-34 is 8
Answer:
Step-by-step explanation:
The confidence interval gives a range of values that could contain the population mean.
Confidence interval is written as
Sample mean ± margin of error
Confidence interval does not express probability.
Given that the sample mean home price for city A is $189500 and the sample mean home price for city B is $185000, the difference in the sample mean home prices for both cities is
189500 - 185000 = $4500
Since the margin of error for 95% confidence interval for the difference in average home price between the two cities (A-B) to be $3400, then
The upper limit of the confidence interval is
4500 + 3400 = $7900
The lower limit of the confidence interval is
4500 - 3400 = $1100
Therefore, the correct conclusion is
Beatrice can be 95% confident that the average home price is between $1100 and $7900 more in city A than in city B.
