Answer:
148
Step-by-step explanation:
3p + 85 +2p -10 =180
5p+75=180
5p=105
p=21
3p+85
3(21)+85=148
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
Answer:
C
Step-by-step explanation:
The answer is C, its like finding x and then use the x to find the y and you got it
