Answer:
%62.5
Step-by-step explanation:
Im pretty sure you jsut divide 5/8 and then multiply by 100 to get a percent
5/8=.625
.625*100=62.5
%62.5
Answer:
![P(X\geq 20)= P(X=20)+P(X=21)+P(X=22)+P(X=23)+P(X=24)+P(X=25)](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%2020%29%3D%20P%28X%3D20%29%2BP%28X%3D21%29%2BP%28X%3D22%29%2BP%28X%3D23%29%2BP%28X%3D24%29%2BP%28X%3D25%29)
And replacing using the mass function we got:
And adding the values we got:
![P(X\geq 20) = 0.8381](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%2020%29%20%3D%200.8381)
Step-by-step explanation:
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:
![P(X\geq 20)= P(X=20)+P(X=21)+P(X=22)+P(X=23)+P(X=24)+P(X=25)](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%2020%29%3D%20P%28X%3D20%29%2BP%28X%3D21%29%2BP%28X%3D22%29%2BP%28X%3D23%29%2BP%28X%3D24%29%2BP%28X%3D25%29)
And replacing using the mass function we got:

Answer:
1) 225
2) 2304
Step-by-step explanation:
1)
Use geometric mean of legs
![x = \sqrt{(16+9)^2 * 9^2} = \sqrt{25^2 * 9^2} = 25 * 9 = 225](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B%2816%2B9%29%5E2%20%2A%209%5E2%7D%20%3D%20%5Csqrt%7B25%5E2%20%2A%209%5E2%7D%20%20%3D%2025%20%2A%209%20%3D%20225)
2)
Use geometric mean of altitude
![x = \sqrt{(100-36)^2 * 36^2} = \sqrt{64^2 * 36^2} = 64 * 36 = 2304](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B%28100-36%29%5E2%20%2A%2036%5E2%7D%20%3D%20%5Csqrt%7B64%5E2%20%2A%2036%5E2%7D%20%3D%2064%20%2A%2036%20%3D%202304)
Answer:
48
Step-by-step explanation:
-2(1)^2(3(1)^2 – 7(1) + 10)
-2^2(3^2 – 7 + 10)
4(9 - 7 + 10)
4(12)
