Answer:

5 /36

Step-by-step explanation:

Sample space :

Number of faces^number of dice = 6^2 = 36

Sum of 8 on a roll of 2 dies :

Probability = required outcome / Total possible outcomes

Required outcome = number of times a sum of 8 is obtained on a roll of 2 dies = 5

Total possible outcomes = sample space = 36

P(obtaining a sum of 8) = 5 /36

5x^(-2)-17x^(-1)+6<br> i’m so confused pls help<br> will give brainliest

laila [671]

It's a quadratic equation in disguise. If you let $y=x^{-1}$ , then $y^2=x^{-2}$ , and we can rewrite the equation as

$5y^2-17y+6=0$

Solve for $y$ however you like; we get $y=\dfrac25$ and $y=3$ .

But we want to solve for $x$ , so we have

$y=x^{-1}=\dfrac25\implies x=\dfrac52$

$y=x^{-1}=3\implies x=\dfrac13$

Geometry Question: BK bisects angle ABC and M angle ABK=28.3 degrees. Find M angle KBC and M angle ABC.

Nookie1986 [14]

Answer:

$ABK = 28.3$

Step-by-step explanation:

Given

$ABK = 28.3$

Required

Determine KBC

Since BK is a bisector of ABC at B,

this implies that:

$ABK = KBC$

Substitute 28.3 for ABK

$28.3 = ABK$

Reorder

$ABK = 28.3$

Solve a Quadratic EquationUse the following equation to answer the questions:3x2 - 8x + 1 = 314 1 pointWhat is the discriminant?

emmainna [20.7K]

Δ=88

1) Using the Quadratic Equation to Solve

3x²-8x+1=3

3x²-8x+1-3=3-3

3x² -8x -2=0

2)Let's find the discriminant

Δ= (-8)²-4(3)(-2)

Δ=64 -4(3)(-2)

Δ=88
