Answer:

Ta có: P ( A ) P ( B ) = 0 , 12 . Vì P ( A B ) = 0 , 2 ≠ 0 , 12 = P ( A ) P ( B )

nên hai biến cố A và B không độc lập với nhau.

Can you guys help me with number 6 and 7??????

Sergio039 [100]

The formula to find area would be length times height times width. In number six, the prism is 12 cm in length, 9 cm wide, and 5 cm high. So your equation would be 12 x 5 x 9. Your answer would be 540 cm squared.

Don't know about number seven, though

Find the area A of polygon CDEFGH with the given vertices. C(0,5), D(2,5), E(2,3), F(3,2), G(-1,2), H(0,3)

enot [183]

Answer:

The area of the polygon CDEFGH is 7

Step-by-step explanation:

Area of a Polygon

The area of a polygon is generally calculated as the sum of the smaller areas that form its full shape, give each partial area has a known shape, like a square, rectangle, triangle, circle, etc.

The six points given in the question are plotted in the image below. They form a polygon whose area can be divided into two smaller shapes:

The area CDHE is a square of length side 2. Area of a square:

$A1=L^2$

The area HEFG is a trapezoid with bases lengths 4 and 2, and height 1. Area of a trapezoid:

$\displaystyle A2=\frac{b1+b2}{2}h$

Calculate both areas:

$A1=2^2=4$

$\displaystyle A2=\frac{2+4}{2}\cdot 1=3$

Total Area=4+3=7

The area of the polygon CDEFGH is 7

The given line passes through the points (0, −3) and (2, 3).

Fed [463]

If the 2 lines are parallel, their slopes are the same.

The slope of both is
3+3
m = ---------- = 3
2 - 0

If the new line passes through the point (−1, −1), then the equation in point slope form is:

y+1 = 3(x+1).
