Answer:
I KNOW IT I HAD IT LAST YEAR
Step-by-step explanation:
Answer: The point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
Step-by-step explanation:
Let be the sample mean .
We know that the confidence interval for population mean is given by :-
, where E is the margin of error .
Given : Lower bound of the confidence interval = 0.226
Upper bound of the confidence interval =0.604
i.e.
Adding (1) from (2), we get
From (2),
Hence, the point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
Answer:1
Step-by-step explanation:
Both are whole numbers,so 1 is an answer,
18/1=18
21/1=21
4a) The length of WY is congruent to the length of WX so set them equal and solve for n.
5n - 2 = 2n + 7; add 2 to both sides
5n = 2n + 9; subtract 2n from both sides
3n = 9; divide both sides by 3
n = 3; substitute 3 in for the value of n
2(3) + 7 = WY
6 + 7 = WY
13 = WY
4b) First find the value of KN by using the pythagorean theorem (a² + b² = c²) so the value of KN is 17² = 14² + KN² or √19
Then you can use that value to find the value of NL using pythagorean theorem again. 17² = √19² + NL² or √270.
To find OL, divide √270 by 2 to get approximately 8.22
Hope this helps!!
***I actually just realized that the measure of NL is 14 and 1/2 of 14 is 7 so 7 is probably more accurate***
Answer:
$84
Step-by-step explanation:
720x30=21600
21600/100=216
216=markdown (as a number instead of a percentage)
Now subtract that like this
720-216=504
504= sale price
Then do this
504-420=84
<em><u>Therefore it is $84</u></em>
