Answer:

3√3

Step-by-step explanation:

The area of a trapezoid is calculated by multiplying the sum of bases by 2 and that divided by 2

(2 + 4) ÷ 2 × √3 = 3√3

If P(C)=.29, P(D)=.47 and P(C and )= 0, are the events C and D mutually exclusive? Find P(C or D)

abruzzese [7]

Answer:

Step-by-step explanation:

note : P(C or D) = P(C)+P(D) - P(C and )

P(C or D) =0.29+0.47- 0

P(C or D) = 0.76

1.) (-18, -20) (18, 16)

m= 1

2.) (-7, 14) (-11, 4)

m= 5/2

3.) (-5, -4) (3, 9)

m= 13/8

4.) (13, -8) (-9, -1)

What is the slope of a line parallel to the line whose equation is x-6y = 42. Fully reduce your answer.

Maksim231197 [3]

The slop would be 1/6.

you put it into slope intercept form (y=mx+b). parallel lines always have the same slope.

in the blanks below. Find the slope of the line passing through the points (-9, 2) and (9,2). slope:

user100 [1]

I will assume that we are trying to find the slope between (-9,2) and (9, 2)

The slope's equation ⇒ $\frac{y2-y1}{x2-x1}$

Let's set the variables:

(x1, y1) --> (-9, 2)

(x2, y2) --> (9, 2)

Now let's plug them in:

$Slope = \frac{2-2}{9--9} =\frac{0}{18} =0$

Thus the slope of the line is 0.

Hope that helps!
