13. Sarah practiced her flute every day for a week just long enough to drive her mom nuts. Her practice times were: 37, 42, 38, 46, 51, 35, 37. What was the mode for her practice times? *
A. 37 B. 46 C. 51

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

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.
