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%.
Is the answer 44 feet wide? What I did was draw a rectangle an label both widths as 6, that equals 12. Then I subtracted 12 from 96 and got 84 and in order to only get one side length I divided it by 2 and got 42. Next I added 2 to that because the width of one side took up one foot and so did the other side so yeah. I'm just guessing.
By looking at the diagram, we see that angle C is 45 degrees, angle A is 90 degrees, and angle B is unknown
Given that the sum of all the triangle's angle is 180 degrees, angle B is also 45 degrees
This means that we have a 45-45-90 triangle, which has some special properties as shown in the diagram I uploaded.
Thus <u>BC in the simplest term is </u>
Hope that helps!
Answer:x= 0.5,−3
Step-by-step explanation:
12 stamps increased by 125%; find the new amount.
The answer to this is 27.
12 x 2 = 24
12 ÷ 4 = 3
<span>24 + 3 = 27</span>
