Mutiply 5.8 times 1.6 and you will get 9.28
Answer:
24.6 < μ < 27.2
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 25.9 - 1.3 = 24.6 pounds.
The upper end of the interval is the sample mean added to M. So it is 25.9 + 1.3 = 27.2 pounds.
So the correct answer is:
24.6 < μ < 27.2
Answer:14pi and 43.98 (2dp)
Step-by-step explanation:
circumference =2xpixr
radius = 14 divide by2 =7
2x pi x 7=14pi
14pi =43.98229715
=43.98 (2dp)
I don't know if you have to do this on a graph, or just on a blank space. But, noncollinear means, "not on the same line". So, if you were to draw four points in a blank spot on a piece of paper, just draw four points in random places, making sure they aren't all directly in line with eachother. For a graph, use points like: (-6,2), (5,7), (8,3), and (1,-3). Notice that none of them have the same x or y coordinates, so they can't possibly be collinear.
The statement H(30) = H(25) + 5 means that, "when Amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old"
<h3><u>Solution:</u></h3>
Given that,
Baby Amelia's parents measure her height every month
It is given that H(t) models Amelia's height (in centimeters) when she was "t" months old
Given statement is H(30) = H(25) + 5
So, we can say that H(30) = Amelia's height when she was 30 months old
H(25) = Amelia's height when she was 25 months old
So H(30) = H(25) + 5 means that,
Height of Amelia when she was 30 months old is 5 centimeter more than Amelia height when she was 25 years old
Or we can say that,
When Amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old
