Given that P(B|A)=0.86 and P(A)=0.43, what is P(B AND A)? Round to three decimal places.

Answers

Answer 1

Answer:

Step-by-step explanation:

P(B|A)=[P(A and B)]/[P(A)]

0.86=[P(A and B)]/0.43

P(A and B)=0.86×0.43=0.3698≈0.340

Answers

Step-by-step explanation:

The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write

[tex](8x + 28) + (4x - 7) = 180 \Rightarrow 12x + 21 = 180[/tex]

or

[tex]x = 13.25[/tex]

Also, note that the angle (4x - 7) and [tex]\angle{TQS}[/tex] are vertical angles, which means that they are equal to each other. Therefore,

[tex]\angle{TQS} = 4x - 7 = 4(13.25) - 7 = 46°[/tex]

x = 68°, find the measures of angles 1, 2, and 3.

Answers

Answer:

[tex] < 1 = 112 \degree\\ < 2 = 68 \degree \: \\ < 3 = 112 \degree[/tex]

Step-by-step explanation:

As the vertically opposite angles are equal,

[tex]x = < 2 \\ x = 68 \\ so \\ < 2 = 68 \degree[/tex]

As the angles in a straight line is added up to 180°

[tex] < 1 + < 2 = 180 \\ < 1 + 68 = 180 \\ < 1 = 112 \degree[/tex]

Also,

[tex] < 2 + < 3 = 180 \\ 68 + < 3 = 180 \\ < 3 = 112 \degree[/tex]

y=-3x+18

Step-by-step explanation:

since they gave us two points, we can find the slope: (y_2 - y_1)/(x_2 - x_1) -> (6-3)/(4-5)=(3)/(-1)=-3 so the slope is -3. now we have [tex]y=-3x+b[/tex]. next we have to find b. to do this just plug a point into the equation: 3= -3*5 +b, 3=-15+b, b=18. so now we have y=-3x+18

Answers

Answer:

Solve equation [2] for the variable y

[2] y = -2x + 1

// Plug this in for variable y in equation [1]

[1] (-2x+1) + 4x = -3

[1] 2x = -4

// Solve equation [1] for the variable x

[1] 2x = - 4

[1] x = - 2

// By now we know this much :

y = -2x+1

x = -2

// Use the x value to solve for y

y = -2(-2)+1 = 5

Solution :

{y,x} = {5,-2}
