What is the value of minus 6 x cubed minus y squared minus 3 x y if if x = -2 and y = 4

Oksi-84 [34.3K]

Well, "minus 6 x cubed minus y squared minus 3 x y" translates to:

$-6x^{2} -y^{2} -3xy$

Then, if we insert the values for x and y, we get:

$-6(-2)^{2} -(4)^{2} -3(-2)(4)$

When we distribute and multiply:

$144-16-24$

And once we combine like terms:

In a jar, there is a green, a blue, and a red marble. You draw (with replacement) a marble from the jar until you get the green

denpristay [2]

Answer:

The value is $P( X = m ) = (\frac{2}{3} )^{m-1 } * \frac{1}{3}$

Step-by-step explanation:

From question we are told that

The number of types of marbles present jar is n = 3

Generally the probability of drawing a green marble is

$P(g) = \frac{1}{3}$

Generally the probability of drawing a marble that is not green is

$P(g') = 1 - \frac{1}{3} = \frac{2}{3}$

From the question we are told that there will be continuous drawing of marbles from the jar (in such a way that after each marble is drawn it is being replaced) until a green marble drawn

Let m be the number of times marbles has been drawn when a green marble was gotten

it then means that for m - 1 times the marbles where drawn a green marble was not obtain.

Generally the probability drawing m times is mathematically is mathematically represented as

$P( X = m ) = (P(g'))^{m-1 } * P(g)$

=> $P( X = m ) = (\frac{2}{3} )^{m-1 } * \frac{1}{3}$

Determine the 10th term 0.1,0.5,2.5

ivann1987 [24]

Find the pattern first which is multiply by 5. This problem is geometric sequence so you have to use this formula to find the 10th term:
An=AR^n-1
A(10)=0.1(5)^(10-1)
A(10)=195312.5
