An urn contains 20 marbles of which 15 are red and 5 are Blue. suppose you randomly choose a marblem, not its color and return it to the urn. you continue this until you have picked a total of 4 blue marbles. What is the probability tha you get an equal number of Red and Blue marbles.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
