Answer:

As the sucrose concentration is higher in the solution, the water in the balloon, where the sucrose is less concentrated, will tend to leave and try to dilute the outer solution until both sucrose concentrations are equal. But as the water leaves the balloon, the concentration inside will increase, so it will flow outside until both concentrations are equal and not until the outer concentration is similar to the initial concentration in the balloon.

A line passes through the point (-6,3) and a slope of 5/2

ycow [4]

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point on a line

We have

$(-6,\ 3)\to x_1=-6,\ y_1=3,\ m=\dfrac{5}{2}$

Substitute:

$y-3=\dfrac{5}{2}(x-(-6))\\\\y-3=\dfrac{5}{2}(x+6)$

Convert to the slope-intercept form

$y=mx+b$

m - slope

b - y-intercept

$y-3=\dfrac{5}{2}(x+6)$ use the distributive property

$y-3=\dfrac{5}{2}x+\dfrac{5}{2\!\!\!\!\diagup_1}\cdot6\!\!\!\!\diagup^3$

$y-3=\dfrac{5}{2}x+15$ add 3 to both sides

$y=\dfrac{5}{2}x+18$

Convert to the standard form:

$Ax+By=C$

$y=\dfrac{5}{2}x+18$ multiply both sides by 2

$2y=5x+36$ subtract 5x from both sides

$-5x+2y=36$ change the signs

$5x-2y=-36$

15 15 15 5 14 17 8 12 what are the means and median

liq [111]

Answer:

Step-by-step explanation:

Means=15

Median=15

5,8,12,14,15,15,15,17

cross them out until you get to the middle and the middle will be median when there's add them together then divide by 2

14+15=29

29÷2=14.5

A player pays $1 to play a game where three fair dice are rolled. If three 6s are obtained the player wins $500, and otherwise t

Ugo [173]

The chance to win = 1 : 6³ = 1 / 216

To win $500, the player needs to pay $216 on average.
500/ 216 = 2.31
$2.31 win and $1 cost per game gives $1.31 net win.
