A number is selected at random from the set (2, 3, 4, ... 10). Which eventby definition, covers the entire sample space of this experiment?
A.
The number is greater than 2.
OB.
The number is not divisible by 5.
C.
The number is even or less than 12.
OD. The number is neither prime nor composite.
E.
The square root of the number is less than 3.

C

Step-by-step explanation:

A doesn't include the term "2"

B doesn't include "5" or "10"

D doesn't include "10"

SO... it's C

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
