To help students improve their reading, a school district decides to implement a reading program. it is to be administered to the bottom 10% of the students in the district, based on the scores on a reading achievement exam. if the average score for the students in the district is 117.6, find the cutoff score that will make a student eligible for the program. the standard deviation is 23. assume the variable is normally distributed. round value calculations to 2 decimal places and final answer to the nearest whole number

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.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
