Answer:

2x + 1/2 sq. ft

Step-by-step explanation:

Surface area = 2(lw+wh+lh)

Given

length l = x ft

width w = 1/2 ft

height h = 1/2ft

Substitute

Surface area = 2(x(1/2)+(1/2)(1/2)+x(1/2))

Surface area = 2(x/2+1/4+x/2)

Surface area = 2(2x/2 + 1/4)

Surface area = 2(x + 1/4)

Surface area = 2x + 2/4

Surface area = 2x + 1/2 sq. ft

Alla [95]

Answer:

Probability of no one picking up a defective product = 571 / 1540

Step-by-step explanation:

Total number of items = 22

non-defective items = 22-3 = 19

Probability of all three picking up non-defective products

= 19/22 * 18/21 * 17/20

= 969/1540

Probability of at least one picking up a defective product

= 1 - 969/1540

= 571/1540

(=0.371, approx.)
