Answer:
It's false
All quadrilaterals are also rhombus, <u>False</u>
9880 different possibilities are there in Sally's new combination option second 9880 is correct.
<h3>What is permutation and combination?</h3>
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Total unique numbers consists in a Sally locker = 3
From the digits 0 to 39
Total numbers = 40
Apply combination formula:
= C(40, 3)
= 40!/(3!37!)
= 9880
Thus, 9880 different possibilities are there in Sally's new combination option second 9880 is correct.

Answer:
B.)
Step-by-step explanation:
that is a characteristic of a maximum value parabola.
Answer:
False
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = -
, hence
y = -
x + c ← is the partial equation
to find c substitute (- 3, 5) into the partial equation
5 =
+ c ⇒ c = 
y = -
x +
← equation of line
