Answer:
Kindly check explanation
Step-by-step explanation:
Total number of coin flips = 50
Number of times both coins landed head up = 20.
Hence probability of having two heads :
Probability = required outcome / Total possible outcomes
P(both heads up) = 20/50
Comparing 20/50 to 50%
We convert 20/50 to percentage :
(20/50) × 100%
0.4 × 100% = 40%
20/50 is equivalent to 40%
Hence, 40% is less than 50%
Answer:-
Step-by-step explanation:
1-5 marbles are blue you assign them a number and there is 1 red one and he is assign #6
6. K=4
7. N=11
8. C=2
9. R=7
10. R=4
11. Y=1
12. R=7
13. N=7
Fit Fast: a set feet per class => y = Ax
Stepping Up: a monthly fee plus an additioal fee per class => h = Bx + C
You can discard the second and the fourth systems because they do not have the form established from the statement.
The first system produce an obvious result given that is represents an option that is always better than the other 5.5x will be lower than 7.5x + 10 for any positive value of x, and so there is no need to make any comparission.
The third system is
y = 7.5x and y = 5.5x + 10 which need to be solved to determine when one rate is more convenient than the other.
Answer: y = 7.5x and y = 5..5x + 10
