Mass of freight train: 9.98 • 106
= 1057.88 kg
mass of aircraft carrier: 7.3 • 107
= 781.1 kg
difference: 1057.88 - 781.1
= 276.78 kg
= 2.7678 x 10^2
Answer: x=0
Step-by-step explanation:

The corrects answers are B and D for this one.
Since you divide the same side for both the the rectangles on both parts and if the division statements are equaled, then they are similar.
For example;
Answer B.
50 / 10 = 5
and
30 / 6 = 5
Answer D.
7.5 / 2.5 = 3
and
4.5 / 1.5 = 3
Since they both equal the same for both of the rectangles for the answers individually, they are similar polygon rectangles.
Hope this helps!

Answer:
Required Probability = 0.605
Step-by-step explanation:
Let Probability of people actually having predisposition, P(PD) = 0.03
Probability of people not having predisposition, P(PD') = 1 - 0.03 = 0.97
Let PR = event that result are positive
Probability that the test is positive when a person actually has the predisposition, P(PR/PD) = 0.99
Probability that the test is positive when a person actually does not have the predisposition, P(PR/PD') = 1 - 0.98 = 0.02
So, probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition = P(PD/PR)
Using Bayes' Theorem to calculate above probability;
P(PD/PR) =
=
=
= 0.605 .
