D is the correct answer. To solve this use the Multiplication Rule for Independent events. Multipy P(A) times P(B) and if they equal P(A and B), then the probability is independent. If it does not equal P(A and B) then it is not independent.

Given parallelogram ABCD, solve for x
kumpel [21]

Answer:

x=5

Step-by-step explanation:

Set your equation up as following:

6x-10=3x+5

move the 3x to the left side by substracting

3x-10=5

now add 10 to the right side

3x=15

Divide 15 by 3 to isolate x

x=15/3

x=5

A sector with an area of 30(pi) cm^2 has a radius of 10 cm.
Karolina [17]

Answer:

  108°

Step-by-step explanation:

The area of a sector is given by the formula ...

  A = (1/2)r²θ . . . . . where θ is in radians

Solving for θ, we find ...

  θ = 2A/r²

For your given sector, the central angle is ...

  θ = 2(30π cm²)/(10 cm)² = 0.6π . . . . radians

π radians is 180°, so the central angle in degrees is ...

  θ = (0.6)(180°) = 108°

The central angle measure of the sector is 108°.

A line through (4,-2) with slope -3
GalinKa [24]

Answer: y = -3x + 10

Step-by-step explanation:

Using the formula for finding the equation of line ;

y - y_{1} = m ( x - x_{1} )

x_{1} = 4

y_{1}  = -2

m = -3

Substituting into the formula , we have

y - (-2) = - 3 ( x - 4 )

y + 2 = -3x + 12

writing the equation of the line in slope - intercept form , this means that we must make y the subject of the formula , that is

y = -3x + 12 - 2

y = -3x + 10

Can y’all help me?
Tasya [4]

Answer:

402.1 in^2

Step-by-step explanation:

Find the area of the circle with the 18 in. radius first.

Formula for a circle is πr^2

So the area of the circle with the 8 in. radius is 1017.9 in^2

Now do the same for the 14 in. radius circle.

The area for the 14 in. radius circle is 615.8

Now subtract:

1017.9 - 615.8 =

402.1 in^2

hope this helped!
