Answer:
47.5
Step-by-step explanation:
Answer:
61/125 or 0.488
Step-by-step explanation:
Total = 5×5×5 = 125
Numbers with no 4 = 4×4×4 = 64
Atleast one 4= 125-64 = 61
P(atleast one 4) = 61/125 or 0.488
10/12 = 5/6 is your answer
Answer:
x = 65 , y = 64
Step-by-step explanation:
y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is
y - 16 + 2y + 4 = 180
3y - 12 = 180 ( add 12 to both sides )
3y = 192 ( divide both sides by 3 )
y = 64
then
2y + 4 = 2(64) + 4 = 128 + 4 = 132
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2y + 4 is an exterior angle of the triangle , then
x + 67 = 132 ( subtract 67 from both sides )
x = 65
