Answer:

x=24

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

4x-2 + 3x+14= 180

Combine like terms

7x +12 =180

Subtract 12 from each side

7x+12-12 = 180-12

7x = 168

Divide each side by 7

7x/7 = 168/7

x =24

Answer:

x = 24

Step-by-step explanation:

This is going to be a different type of equation. These are supplementary angles, meaning that the sum of the two angles is = to 180. All you have to do is to combine the two equations and set it = to 180.

Set up you equation like this:

4x - 2 + 3x + 14 = 180

Combine like terms:

4x + 3x = 180 + 2 - 14

7x = 168

x = 24

Suppose that 1/2 of all cars sold at a Nissan dealer in a given year are Altimas, 1/3 are Maximas, and the rest are Sentras. Sup
IRINA_888 [86]

Answer:

(1) Not conditional, 5/8

(2) Not conditional, 1/12

(3) Conditional, 1/18

Step-by-step explanation:

Fraction of cars sold

Altima = 1/2

Maxima = 1/3

Sentra = 1 - (1/2 + 1/3) = 1 - 5/6 = (6 - 5)/6 = 1/6

Fraction of cars sold with moon roof

Altima = 3/4 × 1/2 = 3/8

Maxima = 1/2 × 1/3 = 1/6

Sentra = 1/2 × 1/6 = 1/12

(1) Probability (a randomly selected car has a moon roof) = 3/8 + 1/6 + 1/12 = (9+4+2)/24 = 15/24 = 5/8

(2) Probability (a randomly selected car has a moon roof given it is Sentra) = 1/12

(3) Probability (a randomly selected car is a Maxima if it has a moon roof) = 1/3 × 1/6 = 1/18

A conditional probability uses if (as a condition) in making statements or asking questions

An unconditional probability makes statement or ask question without the use of condition (if)
