A flower bed contains 52 roses and 48 tulips. Two flowers have wilted, what is the probability that the flower is a tulip.

Sergio [31]2 years ago

First, I add 52 to 48 to get the total amount of flowers.  52 + 48 = 100.  Out of those 100, there are 48 tulips.  If one flower wilted, the probability of it being a tulip would be 48/100, or 0.48.  If a second flower wilted (with only 99 flowers left, and only 47 tulips left), the probability of it being a tulip is 47/99 or 0.474747...  To get the probability of both of those being tulips, multiply the two together.  48/100 * 47/99 = 2256/9900 (then, simplify to 376/1650)

I hope this helps! Can I have Brainliest? :)

Zamir needs to determine the height of the building
Svetach [21]

Answer:

Height of the building = 115.4 ft.

Step-by-step explanation:

Height of building = AB + 46.4 + CD + 30.5

By applying Pythagoras theorem in ΔABP,

(26)² = (10)²+ (AB)²

676 - 100 = AB²

AB² = 576

AB = 24 ft

By applying sine rule in ΔCDE,

cos(60°) = \frac{CD}{CE}

CD = CE × \frac{1}{2}

CD = \frac{29}{2}

CD = 14.5 ft

Total Height = 24 + 46.4 + 14.5 + 30.5

                     = 115.4 ft

Find the directional derivative of the function at the given point in the direction of the vector v. f(x, y, z) = xyz , (3, 3, 9
Anna [14]

The derivative of f(x,y,z) in the direction of a vector \mathbf u is

\nabla_{\mathbf u}f=\nabla f\cdot\dfrac{\mathbf u}{\|\mathbf u\|}

With f(x,y,z)=xyz, we get

\nabla f=(yz,xz,xy)

and \mathbf u=(-1,-2,2),

\|\mathbf u\|=\sqrt{(-1)^2+(-2)^2+2^2}=3

Then

\nabla_{(-1,-2,2)}f(3,3,9)=(27,27,9)\cdot\dfrac{(-1,-2,2)}3=-21
