A six-sided die is rolled in a trial. What are the chances that the outcome is 2 or more?

To have the outcome of 2 or more, we can roll out a 2,3,4,5 or 6.

So, the chance of getting the outcome is 2 or more is 5/6

And, 5/6 is pretty much likely to happen. (around 80% or so)

A lamina with constant density rho(x, y) = rho occupies the given region. Find the moments of inertia Ix and Iy and the radii of

jenyasd209 [6]

Answer:

Ix = Iy = $\frac{ρπR^{4} }{16}$

Radius of gyration x = y = $\frac{R}{4}$

Step-by-step explanation:

Given: A lamina with constant density ρ(x, y) = ρ occupies the given region x2 + y2 ≤ a2 in the first quadrant.

Mass of disk = ρπR2

Moment of inertia about its perpendicular axis is $\frac{MR^{2} }{2}$ . Moment of inertia of quarter disk about its perpendicular is $\frac{MR^{2} }{8}$ .

Now using perpendicular axis theorem, Ix = Iy = $\frac{MR^{2} }{16}$ = $\frac{ρπR^{4} }{16}$ .

For Radius of gyration K, equate MK2 = MR2/16, K= R/4.

Which is greater .75 or 7/8

soldier1979 [14.2K]

Answer:

.75 < 7/8

Step-by-step explanation:

Lets change the decimal to a fraction

.75 = 75/100

Divide the top and bottom by 25

75/100 = 3/4

Multiply by 2/2

3/4*2/2 = 6/8

6/8 < 7/8

so .75 < 7/8
