<em>I would say that your answer is </em><em>44</em>
1.5 minutes = 90 second
The probability density function is

so the probability of interest is


9x-7x= 2x
because both are x's now u cant add nor subtract anything to Y so just leave it alone but u can add 6+14
2x+8y=20
We simply divide the mass of Saturn with the mass of Earth.
5.686 x 10^26 / 6.04 x 10^21
The rule of significant figures when dividing numbers is that the least amount significant figures must be used in the quotient.
Therefore, Saturn is 9.41 x 10^4 times heavier than Earth.
