Answer:

280

Step-by-step explanation:

The formula for the area of a triangle is A=h*b÷2 so, we multiply 28*20 = 560, then we divide 560 ÷ 2 = 280, therefore, 280 is our answer

Find the value of this expression if x=9 x2 + 6 / x - 6

GREYUIT [131]

Answer:

87/3

Step-by-step explanation:

Here we are given the expression:

$\frac{x^{2}+6}{x-6}$

Now we have to find the value of this expression when x equals 9.

So plugging the value of x as -9 in the given expression:

$\frac{x^{2}+6}{x-6}$

$=\frac{(9)^{2}+6}{9-6}$

=87/3

So on evaluating we get the value of expression as 87/3.

Bob is asked to construct a probability model for rolling a pair of fair dice. He lists the outcomes as 2, 3, 4, 5, 6, 7, 8,

vichka [17]

Answer and Step-by-step explanation:

For 2 dice, we have 36 possibles outcomes:

D₁ = {1,2,3,4,5,6}

D₂ = {1,2,3,4,5,6}

U = ({1,1};{1,2};{1,3};...;{2,1};{2,2};...;{6,6})

This way, it's 6 for D₁ and 6 for D₂, 6.6 = 36

The possible 3 that might appear when rolling a pair of dice would be

{1,2} and {2,1}, so, 2.

The probability of rolling 3 is 2/36 = 1/18
