Slope intercept form: y = mx + b

first distribute the 4 to both x and -3
4(x) = 4x
4(-3) = -12

y + 2 = 4x - 12

subtract 2 from both sides to isolate the y

y + 2 (-2) = 4x - 12 (-2)

y = 4x - 14

y = 4x - 14 is your answer

hope this helps

The answer would be

y = 4x -14


y +2 = 4(x-3)

y+2 = 4x -12

y  = 4x -12 -2

y  = 4x -14    (slope intercept form)

Find the coordinates of the midpoint M of the segment with the given endpoints. Then find the distance between the two points. R
MrRa [10]
Question 1. Midpoint

Answer: M(-2,4)

Explanation:

1) The coordinates of the midpoint, M (x,y) between two points (x₁,y₁) and (x₂, y₂) are:

x = (x₁ + x₂) / 2 and y = (y₁ + y₂) / 2

2) Replacing the coordinates of the given points P (-4, 1) and Q (0,7) you get:

x = (- 4 + 0) / 2 = - 2, and
y = (1 + 7) / 2 = 4

So, the answer is M (-2,4)


Question 2: The distance between the two midpoints is:

Answer: 7.21


Explanation:

1) Use the formula of distance, which is an application of Pythagora's theorem:

d² = (x₂ - x₁)² + (y₂ - y₁)²

2) Substitute values:

d² = (0 - (-4))² + (7 - 1)² = 4² + 6² = 16 + 36 = 52 ⇒ d = √52 ≈ 7.21

g European roulette. The game of European roulette involves spinning a wheel with 37 slots: 18 red, 18 black, and 1 green. A bal
butalik [34]

Answer:

The expected value and standard deviation of your total winnings are -$0.081 and $3 respectively.

Step-by-step explanation:

We are given that the game of European roulette involves spinning a wheel with 37 slots: 18 red, 18 black, and 1 green.

Gamblers can place bets on red or black. If the ball lands on their color, they double their money. If it lands on another color, they lose their money.

Let the probability of the ball landing on red slot = \frac{18}{37}

The probability of the ball landing on black slot = \frac{18}{37}

The probability of the ball landing on green slot = \frac{1}{37}

Now, it is stated that Gambler can place bets only on the red or black slot, so;

The probability of winning the bet will be = \frac{18}{37}

and the probability of losing the bet will be = \frac{18}{37}+\frac{1}{37}

                                                                        = \frac{19}{37}

If the gambler wins he gets $3 and if he loses he will get -$3.

So, the expected value of gambler's total winnings is given by;

E(X) = \sum X \times P(X)

        = \$3 \times \frac{18}{37} + (-\$3 \times \frac{19}{37})

        = \$3 \times (-\frac{1}{37})  = -$0.081

Now, the standard deviation of gambler's total winnings is given by;

S.D.(X) = \sqrt{(\sum X^{2}  \times P(X))-(\sum X \times P(X))^{2} }

So, E(X^{2})=\sum X^{2}  \times P(X)

                 = \$3^{2}  \times \frac{18}{37} + (-\$3^{2}  \times \frac{19}{37})

                 = \$9 \times (\frac{18}{37}+\frac{19}{37})  = $9

Now, S.D.(X) = \sqrt{\$9-(-\$0.081)^{2} }

                     = \sqrt{8.993}  = $2.99 ≈ $3

Hence, the expected value and standard deviation of your total winnings are -$0.081 and $3 respectively.
