Answer:
a. 2,440 km
b.
Step-by-step explanation:
a. Diameter of Mercury =
Radius of Mercury = ½ of its diameter =
Radius of Mercury =
To convert the radius to ordinary number, multiply 2.44 by 1,000.
Radius of Mercury as an ordinary number =
b. Mass of Jupiter =
Mass of Saturn =
Difference between mass of Jupiter and mass of Saturn = (subtract 5.68 from 1.898 = 5.68. we would retain the largest exponent, which is raised to the lower of 27.)
The probability that the reaction time for this density function is at most 2.5 seconds is equal to 0.9.
<h3>What is a density function?</h3>A density function can be defined as a type of function which is used to represent the density of a continuous random variable that lies within a specific range.
<h3>How to calculate the probability that reaction time is at most 2.5 seconds?</h3>P(X ≤ 2.5) = Fx(2.5)
Fx(2.5) = 3/2 - 3/2(2.5)
Fx(2.5) = 3/2 - 3/5
Fx(2.5) = 0.9.
