Find EF in parallelogram CDEF.

Ne4ueva [31]

Answer:

Step-by-step explanation:

EF = CD

FC = DE These equal lines are properties of a parallelogram.

2y = 3y - 17 Add 17 to both sides

2y + 17 = 3y Subtract 2y from both sides.

2y-2y+17 =3y-2y

y = 17

CD = y + 43

CD = 17+43

CD = 60

Since CD = 60 then FE = 60

A 12-sided die is rolled. The set of equally likely outcomes is {1,2,3,4,5,6,7,8,9,10,11,12}. Find the probability of rolling

vfiekz [6]

Answer:

Probability of rolling a number greater than 2 = 5/6

Step-by-step explanation:

Given:

Number;

1,2,3,4,5,6,7,8,9,10,11,12

Find:

Probability of rolling a number greater than 2

Computation:

Number greater than 2 = 10

Probability of rolling a number greater than 2 = Number greater than 2 / Total number

Probability of rolling a number greater than 2 = 10 /12

Probability of rolling a number greater than 2 = 5/6
