Area of room: 7 x 6.5 = 45.5 sq. M.
Area of rug: 22/7 x 1.75^2 = 9.625 sq. M.
Area of loot not covered: 45.5 - 9.625 = 35.875 sq. M. ( round answer if needed)

Answer:
y=4
Step-by-step explanation:
-4y+8=4(2y-2)-2(-16+8y)
or -4y+8=8y-8+32-16y
-4y-8y+16y=-8+32-8
4y=16
y=4
Answer:
P(1 |F) = 10/17
Step-by-step explanation:
Let events
1 = restaurant 1
2 = restaurant 2
F = full-time worker chosen
P = part-time worken chosen
P(1 and F) = 1/2 * 10/16 = 5/16
P(2 and F) = 1/2 * 7/16 = 7/32
P( (1 or 2) and F ) = P(F) = 5/16+7/32 = 17/32
P(1 | F) Probability of choosing restaurant 1 given a full-time was chosen
= P(1 and F) / P(F)
= 5/16 / (17/32)
= 5/16 * 32/17
= 10 / 17
