Answer:

Step-by-step explanation:

Count the number of sections.

... 12!

Now count the number of sections with a label of 5.

... 3!

So the probability of getting a 5 with one spin is $\frac{3}{12}$ or 25%.

Now we can calculate the probability of getting a 5 with 150 spins.

$P(5)=0.25*150$

$P(5)=37.5$

The closest answer is 40.

Answer:

C) 40 times

Step-by-step explanation:

Out of the 12 parts, 3 of those are labeled 5.

That means that there is a 3/12 = 1/4 chance that you will land on it when you spin the spinner.

Out of 150 spins, if you get 5 on about 1/4 of them, about 150 * 1/4 = 37.5 ≈ 40 times will yield 5.

Write an equation of the line containing the point (3,5) and perpendicular to the line 4x-3y=5

ICE Princess25 [194]

Answer:

Step-by-step explanation:

In order to write the equation of the line perpendicular to the given line, we first have to know what the slope of the given line is, and there's no way to tell by looking at it in its current form, which is standard. We need to solve that equation for y to determine the slope of that line. Solving for y:

$-3y=-4x+5$ and

3y = 4x - 5 (just change all the signs so our y term isn't negative anymore...yes, you're "allowed" to do that!) and

$y=\frac{4}{3}x-\frac{5}{3}$ So we can see now that the slope of this line is 4/3. That means that the perpendicular slope is -3/4. Passing through the given point (3, 5):
