Y ~ Po (λ)

P(Y < 2) = P(Y ≤ 1) = 0.04

Plug into the pdf for Po(λ), and solve for λ

After that, use your answer to find P(Y > 5)

You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as

Margaret [11]

Answer:

5/162

Step-by-step explanation:

There's a 5/9 chance that you spin an odd and a 1/2 chance you get heads and a 1/9 chance you get a 3 on the spinner multiply the fractions together and get 5/162.

Surface area of a cylinder. (see attached image please)

Zolol [24]

Answer:

$\large{ \tt{❃ \: EXPLANATION}} :$

Firstly you need to remember the formula to find out surface area of a cylinder - Surface area of a cylinder = 2πr ( r + h ) where r is the radius of a circular face and h is the height of the cylinder.

We're provided : Diameter of cylinder = 12 which means radius ( r ) = 6 cm [ Radius is the half of diameter ] & Height ( h ) = 25 cm & we know pi ( π ) = 22/7.

$\large{ \tt{❁ \: LET'S \: SOLVE}} :$

$\large{\boxed{ \tt{☄TOTAL \: SURFACE \: AREA \: OF\: CYLINDER= 2\pi \: r \: ( \: r + h)}}}$

- Plug the values & then simplify !

$\large{↦2 \times \frac{22}{7} \times 6(6 + 25) }$

$\large{↦2 \times \frac{22}{7} \times 6 \times 31}$

$\boxed{\large{↦1169.14 \: \tt{ {cm}^{2} }}}$

Hence , The surface area of given cylinder is 1169.14 cm²

PLEASE HELP WILL MARK BRAINLIEST!!

Arturiano [62]

Answer:

Yes.

Step-by-step explanation:

Though x and y can be achieved in a system of equations. The equation

x (t)=0.0411905(t^2)+(-0.164619)t+28.0114

And

y (t)=-0.024127(t^2)+(-0.591143)t+(-87.4403)

Are not system of equations but rather two different models of equations. Nevertheless

To find t in the first equation, x(t) has to be equal to zero.

When the t is substituted in the second equation, t will completely disappear. Given the value of y(t) and vice versa.
