Hello!

Experimental probability is the probability in relation to the data that has been collected. In this example, adding up the times spun we get 18 times spun. Where red was spun 6 times, this is 1/3 of what was done.

Our answer is B) 1/3.

Hope this helped!

A line whose equation is 3/2y =3x-6 is parallel to a line with a general equation ax+by+c=0 passing through the points (3,2) . F

lana66690 [7]

Answer:

$\frac{1}{6} x+3y+\frac{13}{2}$ or x + 18y + 39

Step-by-step explanation:

$\frac{3}{2} y$ = $3x-6$

→ First multiply everything by 2 to get rid of the fraction

3y = 6x - 12

→ We want to find the equation that's parallel to this line and passes through (3 , 2). The first thing we know about parallel lines is that the gradient is the negative reciprocal so,

$3y = -\frac{1}{6} x+c$

→ Now we substitute in the values (3 , 2)

$6 =- \frac{1}{2}+c$

→ Add $\frac{1}{2}$ to both sides to isolate c

$\frac{13}{2} =c$

So the equation of the line that is parallel to $\frac{3}{2} y$ = $3x-6$ is $3y =- \frac{1}{6} x+\frac{13}{2}$ but we are not finished we are asked to but the equation in the format

ax + by + c = 0 so,

$3y =- \frac{1}{6} x+\frac{13}{2}$

Rearrange

$\frac{1}{6} x+3y+\frac{13}{2}$

If the question want's the answer in whole numbers then multiply everything by 6

x + 18y + 39

How do I graph a inequality

kakasveta [241]

There are three steps:1)Rearrange the equation so "y" is on the left and everything else on the right.
2)Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
3)Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

Solve for x assuming that the lines are tangent to the circle.

olya-2409 [2.1K]

Answer:

x = 5

Step-by-step explanation:

Tangents from a specific point are equal in length.

3x - 7 = 18 - 2x

5x - 7 = 18

5x = 25

x = 5
