calculate the total volume to determine the amount that equals 20%. To find 20%, note that 20% is equal to 1/5. Hence, vcone = 1/3(hpir^2), and multiplying by 1/5 gives vcone = 1/15(hpir^2). From the given parameters, with d = 4.8, it follows that d/2 = r. Calculating, 4.8/2 yields r = 2.4. Considering the height h = 10, we can determine V to be 1/15(10pi(2.4^2)), which results in V = 1/15(10pi(5.76)) leading to V = 1/15(57.6pi), hence V = 3.84pi. Converted, this is 12.0637 cubic inches, representing 20% of the vase. With a rate of 0.5 cubic inches per minute, using the relationship 0.5 times t = 12.0637 and dividing by 0.5 gives t = 24.1237, approximately 24 minutes. Step-by-step explanation:

<span>The outcome = probability of choosing exactly 2, 3, 4, or 5 passing plays. The probability of selecting exactly two passing plays is given by: (8C2)*(9*8)* (15*14*13*12*11*10) /(26*28*.....19) where: 8C2 represents the combinations of choosing two from 8 and probability that the first passing play is selected = 9/26 probability that the second passing play is chosen = 10/25, and so forth you can similarly calculate the other three scenarios and sum them to find the total probability.</span>
