Answer:
9
Step-by-step explanation:
After 81 passengers get off, only 9 passengers remain on the train of the original 90.
Answer: 43
To get the answer to this question you have to place the numbers form least to greatest and you can cross off numbers on each end until you reach the middle in this case the middle number is 43 so that’s your median
<span> The surface area of a curve y = f(x) generated by revolving about the x-axis on the interval [a,b]
= 2π*∫y*√(1 + (dy/dx)² dx from a to b
In this problem:
dy/dx = 3x²/4
The surface area generated by revolving the curve y = x^3/4 on the interval [0,1] about the x-axis:
= 2π*∫(x^3/4)*√(1 + 9x^4/16) dx from 0 to 1
= π/8*∫x^3*√(16 +9x^4) dx from 0 to 1
u = 16 + 9x^4
du/36 = x^3 dx
= π/288*∫√u du from 16 to 25
= π/288[2/3*u^(3/2) eval. from 16 to 25]
= π/288[250/3 - 128/3]
= π/288[122/3] = 61π/432 </span>
Answer:
The total number of ways to give the answer of the question is 16777216.
Step-by-step explanation:
Total number of questions = 24
The number of possibilities so that the answer is given is only 2. It is either true or false.
So, the total number of ways to complete the test is
