I NEED SERIOUS HELP PLEASE WITH PROBABILITY

erastova [34]

Since its a six sided die the probability for rolling a single number ( like six or four) is always going to be 1/6.

and since the dice has the numbers 1, 2, 3, 4, 5 and 6 on it the probability for the even and the odd numbers are the same the even being 2, 4, 6 and odd being 1, 3, 5. the probability is 3/6 or simplified 1/2.

jok3333 [9.3K]

For 5 taccos 2 cups cheese is needed.

So 10 taccos is 2*(5 taccos)=2*2 cups cheese =4cups

$\begin{gathered} As\text{ 5 taccos=2cup cheese} \\ 1\text{ tacco=}\frac{2}{5}\text{cup cheese} \\ As\text{5 taccos=2cup cheese} \\ 1\text{ cup cheese=}\frac{5}{2}\text{taccos} \\ So\text{ 10 tacco=10}\ast\frac{2}{5}\text{cup cheese=2}\cdot2=4\text{cups} \\ 10\text{ cup cheese =10}\ast\frac{5}{2}\text{tacco}=5\ast5=25tac\cos \end{gathered}$ $35\text{ taccos}=35\ast\frac{2}{5}=7\cdot2=14\text{ cup cheese}$ $24\text{ cup cheese=}24\ast\frac{5}{2}=12\ast5=60tac\cos$

So to convert taccos to cups of cheese multiply by 2/5 and from cups of cheese to taccos multiply by 5/2.

The height after t seconds of an object projected upward with an initial velocity of 48 feet per second from a 210-foot tower ca

svetlana [45]

Given:

The height h of an object after t seconds is

$h=-16t^2+48t+210$

The height of a neighboring 50-foot tall building is modeled by the equation h=50.

The time (t) when the object will be at the same height as the building is found to be t = –2 and t = 5.

To find:

The statement which describes the validity of these solutions.

Solution:

We have,

$h=-16t^2+48t+210$

Here, t is the time in seconds.

For t=-2,

$h=-16(2)^2+48(-2)+210$

$h=-64-96+210$

$h=50$

For t=5,

$h=-16(5)^2+48(5)+210$

$h=-400+240+210$

$h=50$

So, the value of h is 50 at t=-2 and t=5.

We know that time is always positive so it cannot be negative value. It means t=-2 is not possible.

The solution t = 5 is the only valid solution to this system since time cannot be negative.

Therefore, the correct option is C.
