Sec Math 3 - Unit 10 Test Name: 1) The number of eggs laid per year by a 2) The
particular breed of chicken is normally distributed appro-
of 7.2
with a mean of 225 and a standard deviation of
pound
10 eggs. Draw the bell curve labeling the mean
select
and the 3 standard deviations
above or below the mean,
What percent of chickens lay
between 215 and 245 eggs in
a year?
G

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.
