The question is asking to calculate the value of P if they are 1873 teenager are randomly surveyed and 297 of them had moderate to severe sleep disorder and base on my calculation, I would say that the value of P would be 6.31, I hope you are satisfied with my answer and feel free to ask for more
Answer:
(-12, -10)
Step-by-step explanation:
Midpoint M is the average of endpoints A and B:
M = (A +B)/2
2M = A + B . . . . . . multiply by 2; next, subtract A
B = 2M - A . . . . . . the missing endpoint can be found this way
B = 2(-8, 0) -(-4, 10) = (2(-8)+4, 2(0)-10) = (-12, -10)
OK. I did it, and I have the solution.

The length of the deck is (5 + 2x) .
The width of the deck is (4 + 2x) .
If the deck didn't have that big hole in the middle where the pool is,
then its area would be
(5 + 2x) · (4 + 2x) .
When you multiply that all out, you get Area = 4x² + 18x + 20
and the question tells us that the area of the whole big rectangle is 90 yds² .
So we can write
4x² + 18x + 20 = 90 .
Subtract 90 from each side: 4x² + 18x - 70 = 0
Divide each side by 2 : 2x² + 9x - 35 = 0
You can use the quadratic equation to solve that and find out that
x = 2.5 yards, and that's what the question is asking you.

That makes the deck 10 yds high and 9 yds wide.
Total area of the whole big rectangle, (deck + pool ), = 90 yds².
Answer:
She will need 10 full tablets and two thirds of a tablet
Step-by-step explanation:
First we will find how many tablets ana needs for one day:
In each day ana needs 40x2 mg of medicine, they come in tablets of 15 mg. In one day, she needs 80 / 15 = 5 and 1/3 of a tablet.
In two days, she needs double that amount. (5 and 1/3) x 2 = 10 and 2/3
