Volume formula: length x height x width
2 1/2 x 2 1/2 x 5 = 31 1/4
Answer:
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
These bounds are dependent of the sample mean and of the margin of error.
The lower bound is the sample mean subtracted by the margin of error, while the upper bound is the margin of error added to the sample mean.
The confidence interval is likely to contain the true value of the population parameter.
In this question:
Sample mean: 48%
Margin of error: 4%
48 - 4 = 44%
48 + 4 = 52%
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Given:
100m = distance
120s = time
Asked:
Speed = ?
Formula:
Speed = d/t
Solution:
Speed = 100m/120s
Speed = 0.83333333333
Speed = 0.83m/s
Final Answer:
The speed of the sailboat is 0.83m/s
100cm2 that is the answer I got
1/2 - 3/11
Set both denominators (bottom numbers) to 22, so multiply the numerator of 1/2 by 11, and multiply the numerator of 3/11 by 2.
1/2 is now 11/22
3/11 is now 6/22
So, our new question is now : 11/22 - 6/22
Because the denominators are the same, all you have to do is simplify the top numbers.
So, 11-6 = 5
Therefore, your answer is 5/22
~Hope I helped!~
