Answer:
The time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.
Step-by-step explanation:
The function for the height of the bottle rocket (in feet), <em>t</em> seconds after it is launched is:
Compute the value of <em>t</em> as follows:
Thus, the time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.
So with these equations we need to find the y-intercept and the slope because:
y = mx+b
y = f(×)
b = y-intercept
m = slope (slope = rise/run, rise over run)
rise is y-axis
run is x-axis
The y-intercept is (0,-2)
So now we know that one of the answers must have -2 in it
b = -2
m= rise/run = -2/3
The answer is:
y = mx+b
y = f(×)
b = y-intercept
m = slope (slope = rise/run, rise over run)
rise is y-axis
run is x-axis
The y-intercept is (0,-2)
So now we know that one of the answers must have -2 in it
b = -2
m= rise/run = -2/3
The answer is:
Answer: 271.
Step-by-step explanation:
When the prior population proportion of success is not available, then the formula to find the sample size is given by :-
Given : Significance level :
By using the standard normal distribution table ,
Critical value :
Margin of error :
Then , the required minimum sample size will be :-
Hence, the required minimum sample size is 271.
