A jar contains two red marbles, three green marbles, ten white marbles and no other marbles. two marbles are randomly drawn from
neonofarm [45]
Since there are only 2/15 red marbles in the jar, to draw the first marble it would be a 2/15 chance, the next draw would only have 14 marbles, and only 1 red marble, giving you a 1/14 chance. Then you would just need to multiply those two together giving you 2/210, which you can simplify to 1/110

At a concession stand, five hot dog(s) and two hamburger(s) cost $11.75; two hot dog(s) and five hamburger(s) cost $11.00. Find
serg [7]

Answer:

x:hot dogs

y: hamburger

5x + 2y = 11.75

2x + 5y = 11.00

10x + 4y = 23.50

-10x - 25y = -55.00

-21y = -31.50

y = $1.50 each hamburger

2x + 5(1.50)= 11.00

2x + 7.50 = 11.00

2x = $3.50

x = $1.75 each hot dog

Find the equation of the line. A. Y=-3/2x+1 B. Y=-2/3x-1 C. Y=2/3x+1 D. Y=3/2x-1. PLEASE HURRY!!!!!!!!​
galben [10]

Answer:

y = \frac{2}{3} x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (3, 3) ← 2 points on the line

m = \frac{3-1}{3-0} = \frac{2}{3}

Note the line crosses the y- axis at (0, 1) ⇒ c = 1

y = \frac{2}{3} x + 1 ← equation of line
