If I have line segmants with the measurements 3in, 5 in and 8 in; can I make a triangle?

Dimas [21]

Answer:

Equilateral Triangle

Side a = 1

Side b = 1

Side c = 1

Angle ∠A = 60° = 1.0472 rad = π/3

Angle ∠B = 60° = 1.0472 rad = π/3

Angle ∠C = 60° = 1.0472 rad = π/3

C=60°B=60°A=60°b=1a=1c=1

Area = 0.43301

Perimeter p = 3

Semiperimeter s = 1.5

Height ha = 0.86603

Height hb = 0.86603

Height hc = 0.86603

Median ma = 0.86603

Median mb = 0.86603

Median mc = 0.86603

Inradius r = 0.28868

Circumradius R = 0.57735

Vertex coordinates: A[0, 0] B[1, 0] C[0.5, 0.86603]

Centroid: [0.5, 0.28868]

Inscribed Circle Center: [0.5, 0.28868]

Circumscribed Circle Center: [0.5, 0.28868]

Four diners have ordered a platter of desserts. The platter holds 8 chocolate chip cookies and 4 slices of chocolate cheesecake.

Furkat [3]

Answer:

$P(Y>1 \cap Y$

And we can find this probability like this:

$P(Y>1 \cap Y$

And we can replace the values and we got:

$P(Y>1 \cap Y$

Step-by-step explanation:

For this case we define the random variable Y as: the number of slices of cheesecake left on the platter after the first serving. And we have the following distribution for Y:

Y | 0 1 2 3 4

P(Y) | 0.005 0.114 0.429 0.381 0.071

And we want to find the following probability:

$P(Y>1 \cap Y$

And we can find this probability like this:

$P(Y>1 \cap Y$

And we can replace the values and we got:

$P(Y>1 \cap Y$
