To add the two expressions, we can write it as:
4.6x-3 + (-5.3x+9)
We can distribute the plus sign (which means just drop the parenthesis in this case):
4.6x-3-5.3x+9
Now, we can simplify by combining like terms:
-0.7x+6
Answer:
Probability that student has a good grade = 0.525
Step-by-step explanation:
Given
Chances of earning a good grade when assignments are done on time = 0.80
Chances of earning a good grade when assignments are finished during class or late = 0.30
Chances of earning a good grade when assignments are not done at all = 0.05
% of students who completed assignment on time = 0.50
% of students who completed assignment during class = 0.40
% of students who did not completed assignment at all = 0.10
Probability that student has a good grade
= (0.80 *0.50) + (0.30*0.40) + (0.05*0.10)
= 0.525
