expeople1 [14]

Answer:

$Y=(\frac{4}{7}) x+2$

Step-by-step explanation:

$Y=mx+b$

$M=\frac{x2-x1}{y2-y1}$

$M=\frac{0-(-4)}{-10-3}$

$M=\frac{-4}{-7}$

$Y=(\frac{4}{7}) x+2$

Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four e

Alexxx [7]

Answer:

0.25

Step-by-step explanation:

This is the question on conditional probability

Let A - the quadrilateral has four right angles

B - the quadrilateral has four equal side lengths

Required probability = P(B/A)

By definition of continuous probability

$P(B/A) = \frac{P(AB)}{P(A)}$

$P(AB) = \frac{2}{20} =0.10$

P(A) = $\frac{8}{20} =0.4$

Hence given probability = $\frac{0.1}{0.4} =0.25$

Find the surface area of the regular pentagonal pyramid.

mr_godi [17]

Area of each side triangle is 1/2*8*15 = 60. There are 5 of them so the triangles have surface area 300. the pentagon's area 1/2*apothegm*sidelength*sides = 1/2*5.5*8*5 = 110. The total area is therefore 300+110 = 410
