Combine like terms. So that means combine the X's and combine the regular numbers.
- add 2x to 8x
- combine +15 -5
- then add 11 to that
- once you're done, find X by dividing 10x by whatever you have after the = sign
Volume of a ball = (4/3)πr³
When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
Difference = 24416.64 - 7234.56 = 17182.08 cm³
the volume of air in the larger ball is <span>17182.08 cm³ greater than smaller ball </span>
(c/ b * 0) is just (c/0) and you cannot divide by 0
Y ~ Po (λ)
P(Y < 2) = P(Y ≤ 1) = 0.04
Plug into the pdf for Po(λ), and solve for λ
After that, use your answer to find P(Y > 5)
