Total marbles = 14 + 14 = 28
Total purple marbles = 14

P(Purple) = 14/28 = 1/2
⇒ It is equally likely to draw a purple marble or a blue marble.

Answer: (A)

It is neither likely or unlikely to pull a purple marble because there is an even number of blue and purple marbles.

The height of a right circular cylinder is 1.5 times the radius of the base. What is the ratio of the total surface area to the
Naily [24]

Let r represent the radius of cylinder.

We have been given that the height of a right circular cylinder is 1.5 times the radius of the base. So the height of the cylinder would be 1.5r.

We will use lateral surface area of pyramid to solve our given problem.

LSA=2\pi r h, where,

LSA = Lateral surface area of pyramid,

r = Radius,

h = height.

Upon substituting our given values in above formula, we will get:

LSA=2\pi r\cdot (1.5)r  

Now we will find the total surface area of cylinder.

TSA=2\pi r(r+h)

TSA=2\pi r(r+1.5r)

TSA=2\pi r(2.5r)

\frac{TSA}{LSA}=\frac{2\pi r(2.5r)}{2\pi r(1.5r)}

\frac{TSA}{LSA}=\frac{2.5r}{1.5r}

\frac{TSA}{LSA}=\frac{25}{15}

\frac{TSA}{LSA}=\frac{5}{3}

Therefore, the ratio of total surface area to lateral surface area is 5:3.

What is 5x+3y=-15 slope intercept form
muminat
Slope intercept form is y = mx + b
All we really have to do is rearrange our equation!
Subtract 5x from both sides
3y= -5x - 15 is your slope intercept form.
