P(hemoglobin level between 9 and 11) = P(age between 25 and 35 years)..
If you can't read it, I'll do my best to translate:
Z) 10^2 + 5^2 = 125
√125 = 11.18 = Z
Y) tan-1(5/10) = 26.57°
90 + 26.57 = 116.57
180 - 116.57 = 63.43°
5 ÷ sin(63.43) = 8.88 = Y
X) 11.18^2 + 8.88^2 = 203.8468
√203.8468 = 14.28
14.28 - 10 = 4.28 = x
All numbers are rounded to 2 decimal places, if you need any explanations for why I did something then just let me know :)
I hope this helps!
Hi!
length = l = 2 * width = 2 * w
Area = l * w = l * 2 * l = 2 * l^2
2 * l^2 = 72
l^2 = 72/2 = 36
l = square root of 36
l = 6
l = 2 * w => w = l/2 = 6/2 = 3
Perimeter = 2 * l + 2 * w = 2 * 6 + 2 * 3 = 12 + 6 = 18 feet
Hope this helps!
Answer:
x = 3/4 or x = 0.75
Step-by-step explanation:
y=2x²-3x+4
y'=4x-3 = 0
x = 3/4 .... answer
or
x = - b/2a ...y=ax²+bx+c
x = - (-3)/(2*2) = 3/4
We can see that
lies just before 0,
lies between 2 and 3m and
lies between 4 and 5. So, we have
![-1 < a < 0,\quad 2 < b < 3,\quad 4 < c < 5](https://tex.z-dn.net/?f=%20-1%20%3C%20a%20%3C%200%2C%5Cquad%202%20%3C%20b%20%3C%203%2C%5Cquad%204%20%3C%20c%20%3C%205%20)
In particular, this implies that
![-1+4 < a+c < 0+5 \iff 3 < a+c < 5](https://tex.z-dn.net/?f=%20-1%2B4%20%3C%20a%2Bc%20%3C%200%2B5%20%5Ciff%203%20%3C%20a%2Bc%20%3C%205%20)
So, the correct order would be
![-2,\ b,\ a+c](https://tex.z-dn.net/?f=%20-2%2C%5C%20b%2C%5C%20a%2Bc%20)
