Answer:
29.8 units
Step-by-step explanation:
To answer, allow the width of the frame to be represented by x. The dimensions of the frame should then be, 11+2x and 6+2x. Subtracting the area of the inside of the frame from the area of the outside should be able to give us 18 cm². The equation,
(11 + 2x)(6 + 2x) - (11)(6) = 18
The value of x from the equation is equal to 0.5. Thus, the width of the frame should be 0.5 cm.
Step-by-step explanation:
P(heads) = ½, and P(tails) = ½
a) P(5 heads) = (½)⁵ = ¹/₃₂
b) P(5 tails) = (½)⁵ = ¹/₃₂
c) P(at least 1 head) = 1 − P(all tails) = ³¹/₃₂
