Answer:Depending on how high u do it either by 0,25,50 or 0,50,100
Step-by-step explanation:
Answer:
<u>The radius of the cylinder and sphere is 2.48 cm and the volume of the sphere is 64 cm³</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Volume of a cylinder = π * r² * h
π * r² * h = 48
r² * h = 48/3.1416
r² * h = 15.28
r = 2.48 cm, h = 2.48 cm
Now, we can calculate the volume of the sphere this way:
Volume of the sphere = 4/3 * π * r³
Volume of the sphere = 4/3 * π * 2.48³
Volume of the sphere = 4/3 * π * 15.28
Volume of the sphere = 1.33 * 3.1416 * 15.28
<u>Volume of the sphere = 64 cm³</u>
Answer:
7 and 8 because 52 is between 49 and 64
Step-by-step explanation:
'll use the binomial approach. We need to calculate the probabilities that 9, 10 or 11
<span>people have brown eyes. The probability that any one person has brown eyes is 0.8, </span>
<span>so the probability that they don't is 1 - 0.8 = 0.2. So the appropriate binomial terms are </span>
<span>(11 C 9)(0.8)^9*(0.2)^2 + (11 C 10)(0.8)^10*(0.2)^1 + (11 C 11)(0.8)^11*(0.2)^0 = </span>
<span>0.2953 + 0.2362 + 0.0859 = 0.6174, or about 61.7 %. Since this is over 50%, it </span>
<span>is more likely than not that 9 of 11 randomly chosen people have brown eyes, at </span>
<span>least in this region. </span>
<span>Note that (n C r) = n!/((n-r)!*r!). So (11 C 9) = 55, (11 C 10) = 11 and (11 C 0) = 1.</span>
1: -4/1
2: 1/2
3: 1/4
4: -4/1
I hope those r the correct answers
